Transcription

1 COWASH Training Quantum GIS 1 QUANTUM GIS GUIDE FOR WASH FACILITY DATA COLLECTORS AND -MANAGERS Quantum GIS (QGIS) is widely used open source GIS software which usage is very similar to GIS-software market leader ArcGIS. This guide teaches the basics of QGIS and demonstrates how to check if the collected WASH facility points are correctly positioned inside the target woreda/kebele boundaries. Training is conducted using the Amhara region s Yilmana Densa woreda s database as an example. Data is originally downloaded from National WASH-inventory database (NWI M&E MIS) and it has then been prepared for GIS-use in a way that is learned in OpenOffice CALC- and Excel trainings.

2 COWASH Training Quantum GIS 2 FREQUENTLY USED TERMS Vector-file Raster-file Shapefile Layer Attribute table TOC REQUIREMENTS Scalable, computer generated data type Data type for images like aerial photographs, scanned maps, satellite images etc Format of saved vector file. Generally used in GIS software. Either point-, line- or polygon type. When the data is imported to GIS-software, it is referred as layer in TOC Layer s information in table-format Table of Content. Layers toolset normally on the left side of the screen showing all the layers used on the map - Minimum system requirements: Computer with Windows XP or newer, 1GB of RAM, 1.6GHz processor. - Database-file prepared for QGIS (Instructions to do the preparations can be found in OpenOffice-trainings). There is a test-file from Yilmana Densa for training in the Original DATA-folder. - Shapefiles of woreda- and kebele borders. Data can be found in training package. If you are creating maps, data sources has to be mentioned in the map. Data sources are: Woreda borders, roads, towns: EMA Kebele borders: CSA WASH facilities: NWI, your woreda s water office Important! All data is government s property. Publishing of the maps without permission is prohibited. INSTALLING QGIS QGIS is an open source GIS-software which has an active developer base. With QGIS user can visualize, manage, edit and analyze data as well as compose printable maps. Many of the tools in QGIS are similar to ones in ArcGIS so the skills learned with QGIS can easily be transferred to ArcGIS and vice versa. There is installation file for QGIS in QGIS Training-folder. It is either for 32 or 64 bit depending on your operating system. You can check the amount of bits in your Windows as follows: Computers running Windows XP Click Start, right-click My Computer, and then click Properties. If "x64 Edition" is listed under System, you re running the 64-bit version of Windows XP. If you don t see "x64 Edition" listed under System, you re running the 32-bit version of Windows XP. The edition of Windows XP you're running is displayed under System near the top of the window. Computers running Windows Vista or Windows 7 Click the Start button Picture of the Start button, right-click Computer, and then click Properties. If "64-bit Operating System" is listed next to System type, you re running the 64-bit version of Windows Vista or Windows 7. If "32-bit Operating System" is listed next to System type, you re running the 32-bit version of Windows Vista or Windows 7. The edition of Windows Vista or Windows 7 you're running is displayed under Windows edition near the top of the window. Install the correct QGIS, by double clicking installing package. Follow the instructions. After the installation is finished you can delete all the other new shortcuts from your desktop except QGIS Desktop X.X.X. PREPARATIONS

3 COWASH Training Quantum GIS 3 Always save your original data separately from your work files. When you start to work, copy the needed original data for your work. This prevents you from losing any original data in case of mistakes or errors. There is a QGIS-Data-folder in Training-Quantum GIS -folder. This will be the storage for all GIS-data used in training. HOW TO ORGANIZE THE TOOLS Launch QGIS by clicking QGIS Desktop -icon in your desktop. You can also find the software in Start -> All Programs -> QGIS Version -> QGIS Desktop X.X.X Click the grey area of toolset bar with your right mouse button (Image 1) and check only toolsets marked in Image 2. You can also move the toolsets freely to where you want from the toolset handle in the top- or left side of the toolset. Image 1. First arrow showing the gray area and second one toolset handle Image 2. Selecting the correct toolsets for the work

4 COWASH Training Quantum GIS 4 SELECTING THE CORRECT COORDINATE SYSTEM FOR YOUR PROJECT Coordinates are essential part of mapping. When the data is projected in GIS-software, the program has to be told which coordinate system the data is using. If there is wrong coordinate system used the map will not project correctly. In Ethiopia commonly used coordinate system is Adindan UTM. UTM projection is divided to different zones when major part of Ethiopia situates to zone N37 (Image 3). The letter (P, N) indicates the Y-coordinate distance from Equator. GPS-device recognizes the zone automatically. Image 3. UTM zones in Ethiopia Select the Adindan 37 N coordinate reference system (CRS) for your map. From the bottom right corner of the screen click the CRS status button (Image 4). Image 4. Button for adjusting the coordinate system

5 COWASH Training Quantum GIS 5 From the opening window check the Enable on the fly CRS transformation -check box. Write Adindan to Filterfield to find the correct CRS and select it from the Coordinate reference systems of the world -section (Image 5) Image 5. How to select the coordinate system in CRS-menu Latitude/longitude coordinates (degrees) can be converted to coordinates in meters. The mathematic formula is not in the scope of this training course, but you can find converter for example from the webpage: ADDING NEW VECTOR DATA Maps consists of different kinds of data which are stacked upon each other as layers. In this exercise we are adding woreda boundaries -data to the map. This file includes the areas of all the woredas in Ethiopia in the year 2007 (CSA). Click "Add Vector Layer" -tool in your "Manage Layers"-toolset (Image 6). Image 6. Selecting the Add Vector Layer -tool from the Manage Layers toolset You can also use tools from the top menu bar: Layer -> Add Vector Layer... Click "Browse" button (Image 7) and locate the "Eth_woredas.shp" -shapefile in the QGIS DATA/Shapefiles -folder in Training Quantum GIS-folder.

6 COWASH Training Quantum GIS 6 Image 7. Click Browse to select the place for saving the file Be sure to select the shapefile-type (.shp) file. The other files are additional files needed by GIS-software (Image 8) Image 8. Selecting the correct file type It is good to select ESRI Shapefiles (*.shp *.SHP) as a default to help selecting only shapefiles in future. After selecting the file, click Open-button. You will see all the woredas in Ethiopia accordingly to the year Same process is always used to add more data to the map. Raster files, like satellite images or ortho-photographs are added with Add Raster Layer button next to Add Vector Layer button.

7 COWASH Training Quantum GIS 7 BASIC OPERATIONS ZOOMING THE VIEW AND MOVING THE MAP Zoom your map using mouse roll or Zoom In-, Zoom Out-, Zoom to Selection- and Zoom Full tools (Image 9) Image 9. Different zooming-buttons Get familiar with tools in Map Navigation-toolset (Image 10). Try Zoom In -tool dragging a square around desired area with left mouse button pressed down. Try moving the map by keeping the mouse roll pressed down. If you don t have mouse, use Pan Map-tool. Test also right clicking the layer s name in TOC and selecting Zoom to Layer Extent. Image 10. Map Navigation toolset with "Pan Map" tool selected You can turn the layers visible or non-visible by checking the checkbox on and off in Layers-menu (Image 11 Image 11. Changing the visibility of the layers between On and Off EXERCISE 1 Add the Amhara_kebeles.shp file to the map using the same process which was used for Eth_woredas -file. ATTRIBUTE TABLE Attribute table shows the data of the layer in table-format. For example woreda s WASH-facility Excel-database will be managed in GIS-software as an attribute table. To find the woreda according to name, right click the layer name in the Layers-menu and from the opening menu select Open Attribute Table (Image 12). Image 12. How to open the attribute table

8 COWASH Training Quantum GIS 8 Click the W_NAME_NEW headline of the last column from the top row of the attribute table. This will sort the woredas into alphabetical order according to their newer names (Image 13). Yilmana Densa-woreda is split from Adet-woreda after the year when the data was released (CSA 2007). For this reason Adet is used for mapping in this exercise. Select your woreda from the list by clicking the row-number 595 on the left (Image 13). Minimize the attribute table and see the woreda (Adet = Yilmana Densa) selected on the map. Image 13. Listing the woredas alphabetically and selecting one woreda CREATING A NEW SHAPEFILE FROM SELECTION Woreda- and kebele maps are large in size which slows down the usage of the software considerably. In this exercise we will select only the areas what we need. This allows better usability since the amount of data what computer has to calculate is reduced. Check that you have Eth_woredas -layer active in your Layers-menu. If you have Amhara_kebeles-layer in the TOC you can remove it for now by right-clicking its name in TOC and selecting Remove from the opening drop-down menu. Select the Adet (Yilmana_Densa)- and the surrounding woredas with Select Features by area or single click tool (Image 14) Image 14. Selecting selection tool You can select multiple woredas by keeping Control (CTRL) key pressed down from your keyboard (Image 15). Image 15. Multiple woredas selected

9 COWASH Training Quantum GIS 9 You can also draw a square around the woreda by keeping left mouse button pressed down with Select Feature(s) - tool. Change the selection tool from the tool s submenu by clicking the small arrow next to the tool. Try also the other selection methods. After you have selected all the surrounding woredas around your study woreda, click the title of your Eth_woredas layer in the Layers-TOC with right mouse button and from the opening menu, select Save As (Image 16) Image 16. Saving selected area as a new shapefile Give a distinctive name to your new shapefile. In this exercise woreda_selection is used. Click Browse button (Image 17). Search the folder where you want to save your new shapefile. In training we use QGIS-DATA-folder.

10 COWASH Training Quantum GIS 10 Image 17. Saving selection Remember to check the Save only selected features and Add saved file to map checkboxes. First assures that you are only saving the area you selected and latter automatically adds new created layer to the map. After clicking Ok, new shapefile is created. Now you can remove the original Eth_woredas layer from the map by right clicking the name of the layer in TOC (Layers-menu) and selecting Remove. Next remove the selection to be able to do new selection. Click Deselect Features from All Layers -tool which is on the right side of the Select Single Feature tool in toolbar (Image 14) EXERCISE 2 Do the same process to Amhara_kebeles-layer that we did for the Eth_woredas-layer. Select all kebeles in the Yilmana Densa (Adet) woreda. Make sure all the kebeles inside the woreda are selected when you are creating the new shapefile. It doesn t matter if there are some kebeles selected also from the neighboring woredas. Remember that you can check the layers visible and non-visible with the checkbox next to layer name (Image 11) to help in making the selection. Make sure you are making the selection to correct layer! You are selecting kebeles, not woredas now so the respective layer needs to be active in the TOC

11 COWASH Training Quantum GIS 11 CLIPPING DATA To make the map more informative add the road- and town data to the map. Add first the Eth_road.shp -shapefile in a same way as was done in section Adding new vector data (Image 6). These files are also too large for our purposes so we will reduce the size of the files according to the area of woreda_selection layer. For this we don t need to make the selection ourselves but we learn to use Clip-tool instead. From the top bar, select Vector -> Geoprocessing Tools -> Clip (Image 18) Image 18. Launching the Clip-tool From the Clip-window, select first the layer which is going to be clipped (Eth_roads) as Input vector layer. Then select the layer which is going to be used as a clipping area (woreda_selection) as Clip layer. Next select the folder where you want to save the file by clicking Browse-button and then give a name to your new clipped road-shapefile. In the exercise QGIS-DATA-folder and the name Roads_clip are used (Image 19). Be sure to check the Add result to canvas checkbox which will automatically add the new layer to map. Image 19. Selecting settings for clipping

12 COWASH Training Quantum GIS 12 Now when you have the clipped data of your area you can delete Eth_roads -layer to improve usability of the map Right click the Eth_roads layer s name in Layers-menu -> Remove EXERCISE 3 Add the Towns.shp -shapefile to the map and do the clipping in a same way that was done to Eth_roads using the same woreda_selection as Clip Layer. Name the new file as Towns_clip. After clipping, remove the original Towns -layer to improve usability of the map IMPORTING THE COMMA SEPARATED FILE (CSV) TO QGIS In this exercise the CSV-database file from Yilmana Densa woreda is used. Database has been prepared same way as instructed in OpenOffice Calc-training part Converting the NWI M&E MIS Excel sheet for GIS. Select Add Delimited Text Layer-tool from the Manage Layers -toolset (Image 20). Image 20. Selecting the tool for importing the Excel-file Select Browse... and search the Yilmana Densa.csv file from the QGIS DATA/Database -folder. Image 21. Choosing the correct settings for importing the Excel-file

13 COWASH Training Quantum GIS 13 Check the settings are according to Image 21. You can rename the file if needed. In this exercise yilmana_dens is used. Select CSV (comma separated values) as delimiter since we chose comma when we were saving the file in OpenOffice Calc-exercise. This option tells how the cells are differentiated from each other. When the file is saved in Excel, Excel can separate the cells with semicolons or with commas. For Geometry definition, select GPS - X for the X field and GPS - Y for Y axle. This is crucial step. It defines which columns are used to locate the GPS-point. Important! As a result, the table should look similar to one in the window on bottom of the Image 21. (Each attribute are own their own cells) Click OK After approving the settings in the opening window select the Coordinate Reference System (CRS) for the points. In Selected CRS: select Adinjan / UTM zone 37N. Then click OK. FINALIZING THE MAP It is important that all the features of the map are clearly distinguishable from each other. It is also crucial that the most important information is easily caught by the viewer. In this section some tuning options are practiced. CHANGING THE NAME OF THE LAYER Right click layer s name in Layers-menu. From the opening window, select Rename and do the desired change. This affects only the layer s name in the Layers-menu it doesn t affect the actual file s name in file folder. This is important when finalizing the map. Layer names will be shown in the key (legend) of the map. It is also often beneficial for the usability to have clear, easily understandable names for the layers. ADJUSTING LAYER S COLORS We need to be able to see the kebele-borders under the woreda-borders. The layer which is on top in Layers-menu is the one which is seen. Try changing the order of the layers by dragging and dropping them in the Layers-menu to see the effect. Make sure that woreda-layer is on top of kebele-layer before next phase. Go to the woreda-layer s properties. Right click the layer s name and from the opening menu, select Properties (Image 22)

14 COWASH Training Quantum GIS 14 Image 22. How to reach the properties of the layer Select Style-tab from the left-side menu (Image 23) From Symbol layer type-section select Simple fill (Image 23) Change the color of the woreda borders from the Border-section if needed. Clicking small arrow on the right opens the dropdown menu which allows you to select the color freely with Choose color -option From the Fill-section s dropdown menu, select Transparent fill-option. This will make the area inside the borders invisible Change the Border width to 1,0 millimeter by writing or using small arrows on the right side of the field Image 23. Adjusting the layer's appearance

15 COWASH Training Quantum GIS 15 LABELLING THE LAYER To enable the labels for the map, click the kebele_selection -layer in Layers-menu with right mouse-button (Image 22) and select Properties (as in previous exercise). Select Labels-page from the left-side menu. From the Labels-section (Image 24) check the Label this layer with - checkbox. Select FIRST_RK_N-option from the drop-down menu on the right side of the Label this layer with -text. This column includes the kebele names in the database accordingly to CSA Click Apply-button and OK. Image 24. Selecting the correct column for the labels EXERCISE 4 Do the labelling for Towns_clip -layer in a same way we did for kebele names. In the Towns-clip -layer there is Name-column to use for labelling. CHANGING LABEL TEXT STYLE Next we need to distinguish the town-labels from kebele-labels. Go to Towns_clip -layer s properties and to Labels tab and select from lower left side menu the option Text (Image 25). In Text style section, change the font to Arial Black and size to 10 points. Image 25. Choosing the settings for town names

16 COWASH Training Quantum GIS 16 After this select Buffer from the lower left side menu. From the Text buffer section check the Draw text buffercheckbox. This will create white area around the text which will distinguish the text from the background (Image 26). Image 26. Creating a glowing buffer-area around the text Click Apply and OK. ADJUSTING THE SYMBOL FOR THE MAP ITEM It is important to distinguish different layers from each other on a map. For example WASH-facility -symbols needs to be clearly distinguishable from towns. In this exercise the town-symbol is adjusted. Double click Towns_clip -layer s icon in Layers-menu (this is faster way to get to Properties). Then change the appearance of the symbol accordingly to your needs with the options in the Style-tab (Image 27). Image 27. Changing the appearance of the map symbol

17 COWASH Training Quantum GIS 17 USING SAVED STYLES The Eth_roads file includes different kinds of road types. Each type can be formatted separately as was done in previous exercise. Styles can be also saved and used in other layers to fasten the work flow. There is already saved style for Eth_roads in QGIS-DATA/Style folder. Open the properties of roads_clip layer by right clicking the layer s name and from the opening menu select Properties From the left side panel, go to the Style-page (Image 28) and from the bottom of the window, click Load Style - button and locate the Road-style.qml -file in QGIS DATA/Style folder. Double click the file to get it into use. You can now see in the Style-page that the icons for each road type have been changed. Click Apply and OK -buttons. Image 28. Loading the style for the layer Close the window to see the result in the map. EXTRA: CLASSIFYING THE ROAD-FILE This exercise demonstrates how the Road-style which was used in section Using saved styles was done. roads_clip -file consists of several different types of roads but they are all shown with the same thin line with same color. In this section the roads_clip -layer is classified and symbolized accordingly to the road type. Right click roads_clip -layer and select Properties from the opening menu. From the drop-down menu on the top of the Style-tab, select Categorized as classification method (Image 29). Select CLASS as a Column, since in roads_clip - database (attribute table) that column defines the road class. Then click Classify-button which is on the left under the white area with the symbols. Image 29. Selecting the correct classification method Next select correct symbol for each road type from the Symbol-section. Double click the symbol for getting to Symbol selector and create the symbol for the road accordingly to your wishes by changing width and color. You can also select default styles from the list on the bottom right side of the Symbol selector window (Image 30). You can also save the style if needed.

18 COWASH Training Quantum GIS 18 Image 30. Changing the road symbols accordingly to the road type EXCERCISE 5 Follow the instructions from previous chapter and do following exercises A. Classify the Yilmana Densa water point database accordingly to the type of the facility (Source type column). B. Select different symbol for each water point type. C. Save your classification to QGIS-DATA/Style -folder and name it as Waterpoint_style

19 COWASH Training Quantum GIS 19 PREPARING THE MAP FOR PRINTING There is a design tool for map printing purposes in QGIS called Print Composer. If you are familiar with ArcGIS, print composer can be compared to switching from Data-View to Layout-View. With Print Composer you can adjust the layout and add north arrow, scale bar, legend etc. for your map. PRINT COMPOSER PREPARATIONS Before you start to compose your map for printing in Print Composer, position the research area carefully in your normal map-screen in a way you would like it to be in the final map. This is important since positioning of the map later in print composer is difficult. From the top menu bar, select Project -> New Print Composer In the opening Composer title -window give a name to your print composer. Yilmana Densa -is used in the exercise. Click OK and the Print Composer window opens. Print composer is now automatically saved in top menu bar s Project menu s Print Composers-submenu. When different tools are used in Print Composer, the options for the tool are available in the Item properties page in the menu on the right. Initial map settings can be done in the Composition-page in the same menu (Image 31). Select A4-paper size from the Paper and quality section s Preset-drop down menu. Image 31. Adjusting the paper settings in Print Composer Next select the orientation accordingly to your woreda s shape. Yilmana Densa is more wide than high so Landscape is used. When your woreda is higher than wide, use Portrait. From the Orientation-section change the orientation if needed (Image 31). If you are printing the map only as softcopy you can select the size more freely. The bigger the physical size the more details you can show in the map. When you are printing the map as hardcopy then the size depends on your printer s capabilities.

20 COWASH Training Quantum GIS 20 If only digital version of the map is needed you can print the map to a file in XPS-format (XML Paper Specification). Then you can also select larger size for the map for better detail. From the Print Composer s top menu bar, select Composer -> Print From the Print-window, select Microsoft XPS Document Writer and check Print to file checkbox. Click Apply when finished. ADDING THE MAP IN PRINT COMPOSER Add your newly created woreda map to the Print Composer. First it might be a good idea to move all toolsets to the top of the screen. You can freely move them from the toolset handle (Image 1). From the Composer Items -toolset, click Add new map tool (Image 32). Image 32. Composer Items toolset with Add new map tool selected Next paint the area from the paper where you want your map to be projected. For example start from top left corner and drag to bottom right corner with your left mouse button pressed down. If you need to move the map contents use the Move item content tool. (Image 33). Image 33. Move item content tool selected

21 COWASH Training Quantum GIS 21 ADDING THE SCALE BAR AND NORTH ARROW IN PRINT COMPOSER Click the Add new scalebar tool in Composer Items toolset. Click a point in your map where you want the scale bar positioned. You can move the item with left mouse button when you move the cursor above it and when the cursor changes to cross of arrows. You can scale the item from the gray boxes on the corners and sides You can lock the layers from the left side Items-tab by checking the layer s name on the list. Locking prevents you accidentally moving or scaling the items Next open the Item Properties tab from the right side menu. Open the Units, Segments and Display sections and adjust the settings accordingly to your wishes. In Image 34 are shown the options which were used in the exercise. Image 34. Item Properties settings used in exercise EXERCISE 6 Add the North Arrow by clicking the Add arrow tool in Composer Items toolset. Click and hold left mouse button on the point in your map where you want the bottom part of the North arrow positioned then drag straight to up from that point and release the mouse button (North is straight up in our map files). You can then adjust the arrow from the Item properties (Image 35).

22 COWASH Training Quantum GIS 22 Image 35. Adjusting North arrow Item properties ADDING THE LEGEND IN PRINT COMPOSER Legend defines what the used symbols mean in the map. Add the legend by clicking the Add new legend tool in Composer Items toolset (Image 36). Image 36. Composer Item-toolset with Add new legend -tool selected Click a point in your map where you want the legend positioned. When the legend is selected open the Item Properties tab on the menu on the right. You can change the position of the item on the legend list with the blue arrows by first selecting the item and then clicking the arrow up or down. You can alter the name with pen & paper icon and delete or add items with and + -signs (Image 37). Image 37. Adjusting the settings for the legend

23 COWASH Training Quantum GIS 23 After the settings are set you are able to print the map. Printing is done similarly as in any other office-software after selecting from the top menu bar Composer -> Print Final map should look more or less similar to one in Image 38. Image 38. Final map of Yilmana Densa -woreda's WASH facilities EXERCISE 7 Print your map as PDF-softcopy and send it to kimmo.koivumaki@gmail.com.

24 COWASH Training Quantum GIS 24 EXTRA: INSTALLING QGIS PLUGINS (BASIC KNOWLEDGE ON COMPUTERS IS NEEDED) Since QGIS has active developer base there are lots of new tools and features available as plugins. Easiest way of enable plugin is to do it with internet connection. There is lots of information about how to do it in the internet. You can get online help for example from sites: or In this chapter we assume that there is no internet connection available so we install the xytools -plugin manually. Xytools-plugin is for easier using of Excel-files with QGIS. It is originally downloaded from the website: After downloading it was unzipped (right clicked and selected Extract All ). 1. Copy the unzipped xytools -folder from Training package/software/quantum GIS/Plugins/xytools. Note that there is also manual for the usage of the plugin. To see the guide open xytools/docs/index.html. 2. Go to folder C:\Users\YOUR USERNAME HERE\.qgis2\python\plugins\ (in Windows XP there is Documents and settings-folder in between) and paste the xytools-folder there. If there is no such path available. You need to create the python and plugins folders first yourself. Check correct writing! Plugin still needs to be activated before it can be used. 3. Restart Quantum GIS 4. From the top toolbar open Plugins -> Manage and Install Plugins (Image 39) Image 39. Opening the plugin-manager Next QGIS tries to connect to plugin-server which is the easiest way of installing plugins. In this exercise it is assumed that the computer does not have internet connection so click Abort fetching button to skip connection attempt. 5. From the opening list of plugins check the one which is being installed. In this exercise it is XyTools (Image 40) Image 40. Activating the installed plugin

25 COWASH Training Quantum GIS 25 You can now found the XY tools-tool as a last icon in the Digitizing-toolbar (Image 41). If you don t remember how to manage toolbars, check from the chapter How to organize the tools how it was done. Image 41. Icon of the XY tools-plugin in the Digitizing-toolset After installing XY tools-plugin you can import Excel-files (.xsl) to QGIS without need to change them first to CSV-files. Try bringing the Yilmana Densa.xls file to QGIS (NOTE: Excel-file can only include one sheet when using XY tools!) From the top toolbar open Vector -> XY tools -> Open Excel file as attribute table or Point layer (Image 42). Image 42. Opening the Excel-file with XY tools Locate the Excel-sheet in Training-QuantumGIS / QGIS DATA / Yilmana Densa.xls. Next select correct coordinate system (Adindan / UTM zone 37N). In the following ZYTools Coordinate fields window select correct columns for the axels (X: = GPS X, Y: = GPS Y). When the volatile file is in TOC save it as a shapefile as was done in Image 16.

26 COWASH Training Quantum GIS 26 EXTRA: CREATING AND USING KML-FILE IN GOOGLE EARTH AND -MAPS KML-files are generally used in Google s mapping environments. In this section we prepare a file that can be easily used in Google Earth. Right click your woreda s WASH-facility layer in TOC and from the opening menu select Save As From the Save vector layer as -window select first the place where you want to create your file and give it the name with Browse-button. Next change the file format to KML (Keyhole Markup Language file, generally used in online mapping) from Format-section select Keyhole Markup Language [KML] (Image 43). Next change the coordinate reference system to WGS 84 which is generally used in Google Earth. From the CRSsection click the Change-button and find and select WGS 84 (If you don t remember how it was done, you can check the process from the section SELECTING THE CORRECT COORDINATE SYSTEM FOR YOUR PROJECT ). You can also uncheck Add saved file to map option this time since there is no need to show the same data again on the map. Image 43. Creating a KML-file Usage of the KML-file in Google Earth is easy. Launch Google Earth and now you can just drag the KML-file from your file folder to the main screen of the Google Earth. By double clicking the water point icons you can see the data of them. You can also use the KML-file in Google Maps. You have to log in to Google Maps so that you can start My Maps editing mode. Then click Add layer text and from new layer click Import-text (Image 44). Then new windows open where you can drag the KML-file from your file folder. After this all facilities are on Google Map. Image 44. Add layer- and Import-buttons in Google Maps
