3 SprayView AG-NAV Data Processing 1. Typical Initial Operations After finishing the mission and copying the data to a USB key, you can replay the flight by using NavviewW or SprayView program. SprayView is similar to NavviewW for most features. NavviewW can be used for basic flight planning and flight replay. SprayView offers more functions for data analysis, mapping, flight reports and data conversions. This document is intended for both SprayView and NavviewW because most functions are the same in both sofware. However only SprayView will be mentioned as the name of the software. This chapter will help you do the following with SprayView: a) Copy area and flight data files created by an AG-NAV system to your office computer, b) Open an area or project, c) Replay spray data, d) Print out data if you have a printer, and e) Generate a flight report. After finishing a flight, you can use the File Manager to copy the flight data to a USB key, also called thumb drive or USB disk. Notes: For terminology flight data includes spray and flight path, i.e. ferry and turns, data. Spray data consists of Spray On data only. Area data includes spray boundary and everything related to the area, for example exclusion zones, grid lines on spray boundary, key and event logging during the mission, etc For learning SprayView, if you don't have real data on a USB disk, you can use the sample data on your hard disk created when you installed SprayView. When you get more familiar with SprayView, you can do more tasks as required by your job. There are many functions in SprayView that may be helpful for you and clients. You should take advantage of all free seminars provided by AG-NAV to learn more. 3

When done, the cursor will resume to normal pointer icon. 14

15 2. Map Overlay 2.1 Open Map File SprayView supports digital map files in ShapeFile, DXF, MRK, CSV, Bitmap and JPEG formats. The Bitmap and JPEG maps are called raster maps or images. The Shp, DXF, CSV and MRK maps are vector maps. For positional data conversion, SprayView needs to know the Earth datum (ellipsoid) and datum shifts (DX, DY, DZ) of data in the selected map file. For Word Geodetic System 1984 (WGS84) or North American Datum 1983 (NAD83), the datum shifts should be zero. For a local datum, for example NAD27 or CLARKE 1866, the datum shifts must be known. SprayView reads this information from an area (*.no1), a project (*.prj), or the template file ENTRY.NEW. Therefore, before opening a map file, you should open an area/project file first. When overlaying an area with spray data on a map, it is very important to have all geographic (Lat/Long) and UTM coordinate data corresponding to the same Earth datum or Ellipsoid. If the map in a map file corresponds to a different datum, it is needed to apply local shifts to bring the area and data to the right place on the map. To open a map for map overlay or digitizing, do the following: 1) To open an area/project, click Open Area/Project. 2) From the "Open Area (*.no1), Project (*.prj), or entry.new File" dialog, select an area or project file associate with the map for map overlay, or entry.new to create a new area file. If you have spray data and want to overlay data on the map, select the data files. If not, click Cancel to close the Spray Data dialog. Figure 2-1: Open Area 3) Click Open Map. 15

16 4) Select the desired map file, for example TESTAREA.JPG, from the list of files displayed in the "Open Map File" dialog. Always check for the right file extension *.DXF, *.SHP, *.MRK, *.CSV, *.JPG or *.BMP. If the map file is in another folder, select that folder in the "Look in:" box then select the map file. Figure 2-2: Select Map File 5) For a raster map file *.bmp or *.jpg, a registering file is required to georeference the map. SprayView will automatically selects the associate georeferenced or world file (*.pbm or *.jgw). If file not found, SprayView will prompt you to select it as shown below. If everything is OK, the map will be shown on screen. Figure 2-3: Select Registering File 16

17 Figure 2-4: Map Display 2.2 Overlay Data on Map To overlay an area/project and spray data on a map, do the following: a) Open area and map as described in section 2.1. b) Click Go to start the data replay. 17

49 7. Shapefile to AgNav Conversion If you select to use Shapefile in the Guia system, you will have the area and all flight data saved in the Shapefile format. To be able to replay the data in SprayView, you have to convert the data in Shapefile format to AgNav format. Note that in SprayView, a Shape file is considered as a map file. So you can open it as a map. If it has flight data, SprayView will automatically convert it to AgNav file. To convert spray data from Shapefile to AgNav, do the following: 1) Click the button Open Area/Project. 2) Select the ENTRY.NEW file from the list of area and project files. Figure 7. 1: Select ENTRY.NEW 49

50 3) Check the information displayed on screen. Make sure everything is correct and consistent with the spray area. 4) Click Open Map. Figure 7. 2: ENTRY.NEW Information 5) Select the Shape file that contains the information of spray area. The file extension must be.shp, for example testarea2.shp, then click Open. Figure 7. 3: Select Shape File for Area 50

51 6) The area is shown on screen. If the Shape file was generated by Guia, SprayView will create an area file *.no1 automatically. As in the example, the file testarea2.no1 is created. Figure 7. 4: Spray Area in Shape File 7) Select the Shape file for Spray On data. The spray data files are normally in the folder having the same name as that of area Shape file. For example, if the area file is testarea2.shp, the folder name will be testarea2. Figure 7. 5: Select Spray On Data 51

52 8) Highlight and select all the spray on data files. Note that the filenames must have the word spron.shp, for example n spron.shp. When selected, this file will be converted to AgNav data file. If the sproff with the same name exists, for example n sproff.shp, this file will be merged with the spron and all data will be saved to the same AgNav data file. For this example, the AgNav file will be named n t10. By default, the converted n*.t* file is selected automatically. If not, a dialogue will be shown for you to select it. 9) Click Go to replay data. Figure 7. 6: Display Spray On Now you have the area file in *.no1 format and flight data in AgNav format. Next time you can open the area and replay data as usual in SprayView. Note that areas in the shapefile format have at least 3 files for each area: *.shp, *.shx, *.dbf. It may have a *.prj file as well for map projection description. This prj file is not an AgNav project file so do not select them when opening area or project. 52

53 8. AgNav to Shapefile Conversion If you select to use AG-NAV data format in the Guia system, you will have the area files saved in *.no1 files and flight data saved in the AgNav binary format. You can convert area files and flight data into Shapefile for use in ArcView, MapInfo and other GIS software. To convert data, do the following: 1) Click Open Area/Project. 2) Select the desired area file *.no1 or project file *.prj from the list of area and project files. Figure 8-1: Select Area File 3) If flight data files are not selected automatically, select flight data files. Click Open Menu Add Flight Data. 4) Click Go to replay data. 53

57 9. AgNav to KML Conversion KML stands for Keyhole Markup Language which is used to manage 3-D geospatial data in Google Earth. You can use SprayView to convert spray and flight data in an AGNAV file to a KML file for display on Google maps in Google Earth. You can download and install Google Earth from Once you have Google Earth installed in your computer, you can overlay KML files generated by SprayView on Google maps to view the application. If you select Shapefile in the Guia system, you will have to convert Shapefile to AgNav file first, then convert AgNav to KML. To convert AgNav to KML, do the following: 1) Click Open Area/Project. 2) Select the desired area file *.no1 or project file *.prj from the list of area and project files. Figure 9-1: Select Area File 3) If flight data files are not selected automatically, select flight data files. Click Open Menu Add Flight Data. 4) Click Go to replay data. 57

58 Figure 9-2: Replay Flight Path 5) If the data is OK, click Open Menu 6) Select Convert Spray Data AgNav To KML. Note that Convert Spray Data is disabled when no spray data files are selected. Figure 9-3: Select Convert Data To KML 7) Enter the KML filename without extension.kml. By default, the area name is used for KML filename. Figure 9-4: Enter KML Filename 8) Enter the information on the KML Report Settings dialog. The date should be the date when the spray was done. You can select what information to be shown by clicking the square box on each item. 58

59 A checkmark in the box indicates that the item is selected. If Spray Points is checked, each spray record will be saved to the KMZ file as a data point for detail analysis. Figure 9-5: KML Report Settings 9) If you want to save the current information as defaults for future use, click Save Default Info then enter a filename for the settings. If you want to use your own default info saved before, click Load Default Info button then select the settings file. 10) Click Generate KML File to start the conversion. The cursor is changed to hour glass during conversion. It changes to arrow pointer when conversion is done. 11) Note the path and KML/KMZ filename shown in the Conversion done dialogue. Click OK. 59

60 10. Spray Data Display on Google Earth The KML/KMZ files generated by SprayView can be displayed on the 3D maps of Google Earth. First you must have Google Earth installed in your computer. To display a KML file on Google Earth maps, do the following: 1) Select My Computer or run Windows Explorer or File Explorer then go to the folder you have the KML/KMZ file. The output KML file is normally stored in the folder where you have the area file. Figure 10-1: Find KML/KMZ File 2) Select the desired KML or KMZ file *.kmz (double click). As an example, the file testarea.kmz is selected. The area name is testarea. Note that KMZ is the compression of KML file. To save space on your hard drive, SprayView might make the KMZ file instead of KML file. 3) If you have Google Earth installed in your computer, Google Earth will run automatically showing your spray area (red), spray data (pink) and flight path (yellow). 60

61 Figure 10-2: Spray Display on Google Earth s Map 4) Your spray mission is listed in the Temporary Places on the left panel. You can zoom in or zoom out by using the scale bar at the right side of the display to have a better display. You can move the map by holding down the left mouse key and moving the mouse at the same time. Release the mouse button when the map is shown at the desired location. 5) Also at the bottom of the left panel, you see the list of Layers. Google displays the information on the map when it has a check mark. You should check off the Terrain to see your spray area and spray data. Your KML file also has layers to show spray area, spray on and flight path. To view your data layers, click the + button at the left of the area name, for example testarea, to show the layers. 6) By default, all data layers are displayed. You can click on any blue header to see information. For example, by clicking the Spray Area, you will see the area information. Figure 10-3: View Spray Area 61

62 7) Click Spray Report to see the report that you made in SprayView. Figure 10-4: View Spray Report 8) You can explore Google Earth by checking on/off display of layers to see the changes on the map. If Spray Points was selected when generating the KMZ file, you can expand the Spray Points and click at any point on the map to see the spray data. 9) You can view data in 3-D by using the navigation buttons (left, right, up, down with a circle showing N for North). You can add a place mark with a push pin. There are a lot more nice things you can do in Google Earth. Surely you will enjoy learning this software. 62

63 11. Polygon Digitizing in Google Earth From the maps in Google Earth, you can digitize a polygon and save it to a KML file. SprayView can import the KML file and save the polygon as boundary of a spray area in a *.no1 file. To do this, 1) Run Google Earth. 2) Find the map where your spray areas are. 3) Zoom in or out for best view of map. Figure 11-1: Locate Map on Google Earth 4) From the Add menu of Google Earth, select Polygon. The New Polygon dialog box appears and cursor changes to a square icon. You can resize the dialog box to get more space for the map. Make sure your polygon is shown clearly. 63

64 Figure 11-2: Add Polygon 5) Enter the properties of polygon. For polygon or area name, the first 3 characters must be spr followed by a desired name. Do not use a space or special characters. You can use underscore _ or dash -. As an example, we name the area sprtest1. Figure 11-3: Polygon Properties 64

65 Figure 11-4: Enter Polygon Name 6) For Description, you can enter the same as polygon name. 7) As default, the polygon will be painted white on the map. If desired, you can select the color of polygon but this is not necessary. 65

66 Figure 11-5: Enter Color of Polygon 8) Now move the square cursor to the polygon. Click around the outline of polygon to add points. You should click the points in clockwise order. Figure 11-6: Mark Polygon 66

67 9) When done, click the button OK on the dialog box to save the polygon. 10) The new polygon sprtest1 is shown in the Temporary folder in the left panel. 11) To save the polygon to a file, highlight the polygon name sprtest1. 12) Select File Save Save Place As Figure 11-7: Select Polygon to Save Figure 11-8: Save Place As 67

68 13) Enter the KMZ file name. Then click Save. Note that you can also select to save the polygon to a KML file. With the KML file, it s easy to check the content of file if there is a problem. You should know where you save the file. To keep life simple, you should save all files related to Guia or AGNAV system to the AGNAV folder. The advantage is that it s easy to look for it later. Figure 11-9: Save Polygon to KMZ File 14) If you want to make another polygon, repeat steps 2 to ) When all done, exit Google Earth. 68

69 Convert KMZ Files to Spray Area Files 1) Run SprayView. 2) Click Open Area/Project. 3) Select entry.new. Make sure all parameters (Central Meridian, Swath Width, etc..) are correct. 4) Select Open Menu Import Single Conversion (KML/KMZ). 5) Select the desired KML or KMZ file. Figure 11-10: Import Google Earth File Figure 11-11: Select KML/KMZ File 6) If you have more than one polygon in the KML file and want to combine them for spraying together in the Guia, select Yes. If you want to spray all polygons separately, select No. 69

70 Figure 11-12: Combine Multiple Polygons 7) If everything is OK, the polygon or spray area obtained from the KML/KMZ file is shown. Figure 11-13: Check New Area 8) Point the cursor to the center of area and verify if the coordinates of area are correct. The coordinates of cursor are displayed at the bottom of screen. 70

71 Digitizing Exclusion Zones You can digitize exclusion zones from the maps in Google Earth. Follow the procedure to make a spray polygon first and save it to a KML or KMZ file. Then do the following: 1) Run Google Earth and select File Open 2) Select the KML/KMZ file that has the spray polygon, for example sprtest1.kmz. The filename is shown under Temporary Places. 3) Click the filename to show the spray polygon name, i.e. sprtest1. Figure 11-14: Digitize Exclusion Zone 4) Now add a new polygon for an exclusion zone. The procedure is the same as that of digitizing a spray polygon, except that the name of polygon must start with xcl instead of spr. For example, if the spray polygon is named sprtest1, the exclusion zone should be named xcltest1. 71

72 Figure 11-15: Digitize Exclusion Zone Figure 11-16: Enter XCL Name 5) If you have more exclusion zones, just add a new polygon and use the same name for the polygon, i.e. xcltest1. 72

73 6) After finishing all XCL polygons, save them to the KMZ or KML file. To do this, right click on the filename then select Save Place As. Don t change the filename, overwrite it. Figure 11-17: Save Spray Area and Exclusion Zone Now your sprtest1.kmz file has both the spray polygon and exclusion zone. When importing the KML/KMZ in SprayView, the exclusion zone will be saved in a *.xcl file. Figure 11-18: Spray Area and Exclusion Zone 73

74 12. Project (Multiple Areas) Digitizing in Google Earth In the Guia, you can select to spray a single area or multiple areas. Multiple areas can be combined into a project. You can digitize multiple areas in Google Earth and save all polygons to a KML or KMZ file. SprayView can import the KML/KMZ file and generate a project file *.prj for your Guia system. To do this, 1) Run Google Earth. 2) Find the map where your spray areas are. 3) Zoom in or out for best view of map. Figure 12-1: Locate Map on Google Earth 4) From the Add menu of Google Earth, select Polygon. The New Polygon dialog box appears and cursor changes to a square icon. You can resize the dialog box to get more space for the map. Make sure your polygon is shown clearly. 5) Enter the properties of polygon. For polygon or area name, the first 3 characters must be spr followed by a desired name. Do not use a space or special characters. You can use underscore _ or dash -. As an example, we name the area spr_prjtest. 74

75 Figure 12-2: Project Name 6) Now move the square cursor to the polygon. Click around the outline of polygon to add points. You should click the points in clockwise order. 75

76 Figure 12-3: Mark First Polygon 7) When done, click the button OK on the dialog box to save the polygon. 8) The new polygon spr_prjtest is shown in the Temporary Places in the left panel. 9) Save the polygon to a file by highlighting the polygon name. Then select File Save Save Place As 10) Enter the filename or just use the default name, for example spr_prjtest. You can select to save it as a KML or KMZ file. You should know where you save the file. To keep life simple, you should save all files related to the Guia or AGNAV system to the AGNAV folder. 11) After saving, open the file. Select File Open. 76

77 Figure 12-4: Open Project File 12) Look for the file you saved before, for example spr_prjtest.kmz. 13) Select Yes to reload the polygon. Figure 12-5: Select KMZ File to Open 77

Then select the project filename. Click Open. Figure 12-15: Open Project in SprayView 41) When being asked to select spray or flight data files, select Cancel for no data. 42) The project is open showing two spray areas and two exclusion zones. 85

86 Figure 12-16: Project in SprayView 43) You can copy this project to a USB key for use in the Guia or AGNAV system. Note that each project has at least one *.prj file and one *.dsp file. If there are exclusion zones, the *.xcl file will be copied as well. 86

87 13. Variable Flow Rates 13.1 Creating a new Variable Flow Rate area When you have need to spray different application rates for different areas, you can use the Variable Flow Rate function in SprayView to set the application rates for the areas. Figure 14-1: Variable Flow Rate Button To access this function, first open a spray area, project, or a map. Figure 14-2: Open Area/Project for Variable Rate Prescription Then click the button on the toolbar. A new window will appear with functions on the left panel. 87

88 Figure 13-2: VFR Panel If you have a variable flow rate prescription (.vfr) file, you can load them by clicking Load Area and selecting the.vfr file that you want to open. To make a new variable rate prescription file, click the Add Area button. The new area VFR1 is shown in the area list. Click the Add Corners button. Your mouse cursor will change into a crosshair. With the map background and/or spray areas, you can define the boundary for each application rate. Move the mouse to the location where you want to make the area then click on the boundary. When you click, you will make a corner for the area. Click around the area or polygon on the map background to make the boundary for the application rate. If you want to delete any corner, click the Delete Corner button. 88

89 Figure 14-3: Make VFR Area Enter Boundary When you are done, click the End button on the left panel. When you end the area, SprayView will show a dialogue for you to enter the desired application rate. Figure 14-4: Make VFR Area - Enter Desired Application Rate 89

90 Enter the application rate and press OK to accept the value. If you want to change the application rate, click the Change AppRate button then enter a new value. Note the VFR area size and material needed to spray this area are shown on the left panel. To make another VFR area, click the Add Area button and repeat the same sequence above. When you finish making all VFR areas, click the Save to File button to save the areas and rates to a file. Enter the prescription filename. The file extension must be.vfr. Then click Save. Figure 14-5: Make VFR Areas Save To File You can then load the.vfr file for viewing by pressing the button and pressing Load Area. Double click the.vfr file you just made. You should now be able to see the variable flow rate areas on the screen. When done, click the button on the Tool bar to close the VFR function. Important note: When you have one or more polygons inside another polygon, the inner polygons must be defined first and then the outer polygon. A problem will happen if you have the outer polygon defined first then inner polygons as shown in this example. There is one polygon inside a bigger polygon. Polygon 1 is the inner and must be defined first. Polygon 2 is the outer and defined after. During flight, Guia will check if the aircraft is found inside polygon 1, it will use the rate defined for polygon 1. If the aircraft is not inside polygon 1, then Guia will check if it is inside polygon 2 or 3. If the aircraft is not inside any polygons, the default rate defined in the Guia will be used. 90

91 13.2 Using a Prescription in Shape File to Create VFR File To make a variable rate file *.vfr from a prescription file *.shp, do the following: 1) Run SprayView. Then Open an area/project, click Open Area/Project. 2) From the "Open Area (*.no1), Project (*.prj), or Entry.New File" dialog, select an area or project file. The best one would be the area you will work on with this vfr file, for example Halton_Poly1.no1. This is used as reference for geodetic info. 3) Click the button VFR. Figure 14-6: Open Area Figure 14-7: VFR Button on the Tool Bar 91

92 4) On the left panel, click Load Area Figure 14-8: Load VFR Areas 5) Select your shp file. Click Open. Note that this file should have the prescription in the dbf file, i.e. target application rate is read from the WATER column. 6) Polygons and var rates are shown on the left panel. The last polygon is highlighted for your verification. Figure 14-9: VFR Polygon Display 7) Check the data shown on screen, i.e. polygon boundary and application rate. For example, polygon VFR8 has app rate of lit/ha. 92

93 8) Click another polygon on the left panel to check other polygon. If you want to change the application rate, just click Change AppRate and enter the desired value. 9) When finishing checking all polygons, click Save To File. Figure 14-10: Save VFR 10) Enter the VFR filename. The file extension must be.vfr. By default the filename is the same as your shp filename. 11) Click Save to save the file. 12) Click the button on the Tool bar to close Variable Flow Rate function. 13) Copy the vfr file to a USB key. And copy it to the Guia by using File Manager. 14) Remember to select to Load Variable Rates before you select an area to fly or make a new area. The polygons and var rates will be loaded into memory for use during flight. Note that all polygons that have application rate of 0.0 L/Ha or Gals/Acre won t be saved to the vfr file. These polygons should be created as exclusion zones in the spray areas or projects. When applying variable rates, the way the Guia works is that when receiving new coordinates of aircraft, Guia will check if the a/c is inside any polygon. It starts checking from the first polygon in the list, i.e. VFR1, to the last polygon, i.e. VFR8 in this example. If Guia found the a/c is inside a polygon, it will stop checking and use the app rate assigned to this polygon for flow control. Important note: When you have one or more polygons inside another polygon, the inner polygons must be defined first and then the outer polygon. A problem will happen if you have the outer polygon defined first then inner polygons as shown in this example. There are 2 polygons inside a polygon. Polygon 1 is inner and defined first. This is OK. Polygon 2 is the outer and defined second. Polygon 3 is an inner and defined last. This is NOT good because when a/c is inside polygon 3, Guia will find it inside polygon 2 first so it will stop and use app rate of 20 lit/ha for flow control instead of 30 lit/ha defined for polygon 3. 93

94 Figure 14-11: Polygon Conflict To fix this problem, you can use the button Move Up or Down. Highlight polygon 2, i.e. VFR2, then click the button Down to move it down the list. This will make polygon 3 polygon 2 in the list, and polygon 2 becomes polygon 3. Problem solved. Figure 14-12: Fix Polygon Conflict When you change anything, remember to save the changes to file. Just click Save To File and click Save. Confirm overwriting file if the same file is used. 94

95 14. Ground Mapping If you use the GPS Ground Logger system provided by AG-NAV, you can map a boundary of an area on ground. Figure 14-13: GPS Ground Logger When walking or driving around the area, the Ground Logger will log the path and save it to a micro SD card in the system. You can use SprayView to view the path and digitize the spray areas for your Guia system. To do this, 1) When you are ready to mark boundary, turn on the GPS Ground Logger. 2) Read the Quick Start guide to the Ground Logger available on our website. Figure 14-14: GPS Ground Logger - Buttons Make sure that before you start recording, the device has locked onto satellites and that you have a good signal. Go into Measure and press Start to start recording data. 3) Walk or drive around the boundary. If you want to mark a special point, press the MARK button. 4) When finished mapping, press Save and your area will be saved to a TRL file. 5) If you want to map another area, repeat steps 2-4. Every time you press Save, your area data is saved and you start recording your next area. 6) When all mapping is done, turn off Ground Logger. 7) Attach the USB cable to the Ground Logger and plug the USB cable into the computer. 95

96 8) Run My Computer. Open the Ground Logger drive and open the Area folder. Copy the contents of the Area folder onto a place on your hard drive. 9) Run SprayView. 10) Click Open Area and select the ENTRY.NEW file. Check all information shown on screen. The ENTRY.NEW should have correct Geodetics settings (type of coordinates, ellipsoid, datum shifts, etc..). Figure 14-3: SprayView Check ENTRY.NEW 11) When all data is correct, click OK to accept all settings and continue. 12) Click Open Menu, then Convert Map File, then to SHP then Lat/Long. Select the TRL file. Figure 14-15: Getting to TRL File selection 96
