GPS Pathfinder Office Getting Started Guide 77 4 4. 6. 3 Tutorial Loading the Background Files You can specify one or more background files, such as street maps and aerial photographs, for display in the Map window. These files provide a background for the field data files. There are two types of background files: · · Vector files (or drawings) Raster files (or images) Vector files A vector file loads and transforms into any coordinate system The vector file Streets. dxf has its coordinates stored as Latitude/Longitude (WGS-84), but the coordinate system for the project is currently set to UTM. We will need to specify that this file is set to the Latitude/Longitude coordinate system so that the GPS Pathfinder Office software can automatically transform the file from that coordinate system into UTM. Raster files Raster files must be displayed in the coordinate system to which they are `geo-referenced'. Geo-referencing involves matching the pixels in a raster file to real-world coordinates. All raster files must be geo-referenced before they can be loaded into the GPS Pathfinder Office software. The raster file Aerial. bmp is geo-referenced in the UTM coordinate system, and UTM is the coordinate system for the project. You can load this file without setting the coordinate system. You will load the two background files one at a time so that you can see what each background file looks like individually. 78 GPS Pathfinder Office Getting Started Guide Tutorial 4 To load the background file Streets. dxf: 1. The Load Background Files dialog appears. The following dialog appears: 3. Select the file Streets. dxf and click Open to return to the Load Background Files dialog. The following message appears, reminding you to set the correct coordinate system for the new background files (you will do this in Step 5): GPS Pathfinder Office Getting Started Guide 79 4 Tutorial 4. Click OK to clear the message. The following dialog appears: The check mark to the left of the filename indicates that the file loads when you close the dialog. 80 GPS Pathfinder Office Getting Started Guide Tutorial 4 5. You need to specify that this file is set to the Latitude/Longitude coordinate system, so click Change. The Coordinate System dialog appears: GPS Pathfinder Office Getting Started Guide 81 4 Tutorial a. b. Change the System field to Latitude/Longitude. (The Datum field automatically changes to WGS 1984. ) Click OK to accept the selected coordinate system and zone, and return to the Load Background Files dialog: 6. Click OK to load the background file and close the dialog. 82 GPS Pathfinder Office Getting Started Guide Tutorial 4 The Map window displays the background Streets. dxf file: 7. Start to load the second background file, Aerial. bmp, following Step 1 through Step 4 above. We do not need to change the coordinate system for this file as it is geo-referenced in the UTM coordinate system, which is the coordinate system for this project: GPS Pathfinder Office Getting Started Guide 83 4 Tutorial 8. Click OK to accept the selected coordinate system and to close this dialog. A progress bar appears while the files are loading. When it is finished, the Map window should look like this: 84 GPS Pathfinder Office Getting Started Guide Tutorial 4. 6. 4 4 Configuring the Map Window You can configure the Map window to only show certain information. For example, you can change the symbols or line colors used to display features to make it easier to differentiate between features. You can also hide features in the data file or layers in the background files to make it easier to view the data. [. . . ] expected, and you cannot find the symptom in this Appendix. The "PATH" environment variable is not correctly set. At install time, the "PATH" environment variable is set up to include the location of the DOS utilities. Sometimes it is not possible for the installation setup to automatically make the correct changes. [. . . ]
