2 Installation of Quantum GIS 1.8x (Both Mac and Windows based platforms) Installation of Quantum GIS 1.8x (Mac OS Platforms) Installation of Quantum GIS 1.8x (Windows OS based platforms) Go to the following link: 1. Install the Both Frameworks First! eworks/gdal_complete-1.9.dmg 2. Then this one: - eworks/gsl_framework dmg 3. Then Install QGIS from the following site : QGIS dmg Installation of Quantum GIS 1.8x (Windows based platforms) 1. Installation for QGIS 2.01 (32bit) Setup-x86.exe 2. Installation for QGIS 2.01 (64bit) Setup-x86_64.exe 2

3 Installation of Quantum GIS 1.8x (Both Mac and Windows based platforms) Installation of Quantum GIS 1.8x (Mac Platforms) Installation of Quantum GIS 1.8x (Windows based platforms) Some Helpful Mac OS sites : 1. Which Mac OS do I have? - _what_version_mac_os_x_i_have_my_compute r UserGuide-en.pdf Some Helpful Windows OS sites : 1. UserGuide-en.pdf 3

4 Once Installation is Complete (Familiarisation with the QGIS toolbars and Layout) Open QGIS by Selecting the Quantum GIS Desktop (1.8.0) under the Quantum GIS Lisboa folder There may be numerous shortcuts placed on your desktop, you may remove all of them except the underlined above to avoid clutter and confusion.

5 Once Installation is Complete (Familiarisation with the QGIS toolbars and Layout) Familiarise your self by hovering the cursor over each GUI and drop down menu.

7 QGIS Overall Workflow QGIS Project Setup ( create QGIS Project ) Add GIS Vector Data (Wards_2010.shp) Add Tabular Data (SyringeQGIS.csv) Convert.csv to Shapefile (.shp) 9 Analysis 2 : Spatial Join of CityWards and Syringes 7 Analysis 1 : Calculate # of Syringes per Ward 6 Adjust all data for viewing and Save Project. 5 Remove SyringeQGIS.csv file from Project 10 8 Export results to.csv Export results to.csv Label Wards for Display Display Analysis Results by Pie Chart Display Analysis Results by Bar Graph Export Map Display to Image (.jpg,.bmp,.tif ) 7

8 1 QGIS Project Setup ( create QGIS Project ) 2. Select Project Properties 1. First Select the Settings tab 8

9 1 QGIS Project Setup ( create QGIS Project ) 3. Type your Project Title here 4. Ensure this states RELATIVE 5. Select this tab (CRS) and proceed to next page 9

10 1 QGIS Project Setup ( create QGIS Project ) 7. Ensure that this is CHECKED at all times 8. Click APPLY, then OK Next Step 2 > Importing (adding) the City Ward Data to the project. 10

11 2 Add GIS Vector Data (Wards_2010.shp) 1. Click on this GUI to Import your City Ward (Wards_2010.shp) data into QGIS 2. Click on Browse 11

12 2 Add GIS Vector Data (Wards_2010.shp) 3. Navigate to the folder which contains the City Ward Data 4. Ensure that ESRI Shapefiles is selected 5. Click OK 12

13 2 Add GIS Vector Data (Wards_2010.shp) Results should look similar to this ( the colour of the polygons will vary) 13

14 2 Add GIS Vector Data (Wards_2010.shp) One last thing to do is to set the project s coordinate system 6. Highlight and Right Click on the Wards_2010 layer. Click on : > Set Project CRS from Layer At this point, Save your Project Next Step 3 > Importing (adding) the Syringe Data to the project. 14

15 3 Add Tabular Data (SyringeQGIS.csv) 1. Click on this GUI to Import your Syringe (QGISSyringe.csv) data into QGIS 15

16 3 Add Tabular Data (SyringeQGIS.csv) 2. Click on Browse to Locate and select (QGISSyringe.csv) 3. Ensure that Comma is checked 4. Select Longitude for X-Field and Latitude for Y-Field 5. Click OK. 16

17 3 Add Tabular Data (SyringeQGIS.csv) 6. Type WGS84 in the Filter area. 7. Select World Geodetic System 1984 (Authority ID # IGNF : WGS84G). 8. Click OK. 17

18 3 Add Tabular Data (SyringeQGIS.csv) Results should look similar to this ( the colour of the points will vary) At this point, Save your Project Next Step 4 > Converting the.csv file to a shapefile (.shp) for analysis 18

19 4 Convert.csv to Shapefile (.shp) 1. Highlight SyringeQGIS Layer, right click and select Save As. 19

20 4 Convert.csv to Shapefile (.shp) 2. Select ESRI Shapefile. 3. Type SyringeLocations and click Browse. Select the folder in which your data is located. 4. Select Project CRS 5. Check the box for: > Add saved file to map. Click OK Next Step 5 > Removing redundant Files from project. 20

21 5 Remove SyringeQGIS.csv file from Project 1. Highlight SyringeQGIS Layer, right click and select Remove. At this point, Save your Project Next Step 6 > Converting the.csv file to a shapefile (.shp) for analysis 21

22 6 Adjust all data for viewing and Save Project. 1. Double-Click on Square to change how this layer looks. 2. Adjust Colour here. Next Step 7 > Analysis of How Many Syringes are in Each Ward. 22

23 7 Analysis 1 : Calculate # of Syringes per Ward 1. Select the Vector Tab then Analysis Tools, then Points in Polygon. 23

24 7 Analysis 1 : Calculate # of Syringes per Ward 2. Select Wards_2010 for the Polygon Layer 3. Select SyringeLocations for the Point Layer. 4. Browse to your saved data folder and save as SyringesPerWard.shp. Click OK 5. Click Ok and when prompted to add layer to the TOC, Click Yes. 24

25 7 Analysis 1 : Calculate # of Syringes per Ward 6. Right Click on the SyringePerWard Layer and select Open Attribute Table to view results. Next Step 8 > Exporting your Analysis results into a.csv format. 25

26 8 Export results to.csv 7. Right Click on the SyringePerWard Layer and select Save As. 26

27 8 Export results to.csv 8. Select Comma Separated Values and save in a known file location that can be retrieved Next Step 9 > Further Analysis to Spatially Join the Syringe Data to the City Ward data. 27

28 9 Analysis 2 : Spatial Join of CityWards and Syringes 1. Select the Vector Tab then Data Management Tools, then Join Attributes by Location. 28

29 9 Analysis 2 : Spatial Join of CityWards and Syringes 2. Select SyringeLocations as your Target vector Layer. 3. Select Wards_2010 as the Join Vector Layer. 4. Click Browse and name the file > SyringesByWard.shp. Save to an appropriate location. 5. Click Ok and when prompted to add layer to the TOC, Click Yes. At this point, Save your Project 29

30 9 Analysis 2 : Spatial Join of CityWards and Syringes Open the Attribute table and view your results 30

31 10 Export results to.csv 1. Select Comma Separated Values and save in a known file location that can be retrieved 31

32 10 Export results to.csv Open the.csv file in Excel and view your results 32

33 At this point, the analysis is complete. You may do the following procedures to enhance your product for display purposes. 11 Label Wards for Display This procedure will place labels on your map display for a selected layer based on which field you select Display Analysis Results by Pie Chart Display Analysis Results by Bar Graph This procedure will display analysis results in the form of a Pie Chart for a selected layer based on which field you select. This procedure will display analysis results in the form of a Bar Graph for a selected layer based on which field you select. 14 Export Map Display to Image (.jpg,.bmp,.tif ) This procedure will export to a digital image (.jpg,.bmp, etc..) what is displayed in your map window. 33
