Downloading USDA NAIP Imagery for FieldX Office:
- Go to https://nrcs.app.box.com/v/naip
- Click on ‘2017,’ then click on your state’s name. If you can’t find it there, go back and click on ‘2016’ and find your state there.
- Then you can download the appropriate file. You will need to find the FIPS code for the county, which is then displayed in the file name. Here is a link to a resource that can be used as a resource for finding the county code.
- A best practice would be to create a ‘Maps’ folder within the FieldX folder on the C: drive, and save the background maps to that folder.
Preparing NAIP Imagery for addition to Office:
- The maps download as a zipped folder. If another name wasn’t given, the folder defaults to have a name that starts out similar to the following: “Ortho_Imagery_NAIP17_”
- Right-click on the zipped folder, and then click ‘Extract All Files.’ A window will open to ‘Choose a Destination for Extracted Files.’ Type a name and select a location for the unzipped folder that is easy to navigate to. Be sure to include the county name in the folder name chosen.
Using the Layer Manager to add background maps:
- To add background maps to the program, navigate to the ‘Field Maps’ tab.
- Select ‘General Tools,’ then ‘Layer Manager.’ This opens the Layer Manager in a new window.
- Click on the ‘Add Layer’ tool.
- In the interface within the new window, navigate to the folder where the NAIP background aerial imagery maps are stored, and then click on the folder.
- The lower half of the window now shows the map files that are recognized by the program.
- Find the .SID file, and click on the check-box in the ‘Select’ column for the file that should be added. This will be the aerial imagery file.
- The Projection Data, including Datum/Grid, Zone, and Map Units usually can be derived from the aerial imagery file and automatically is filled in. Use these steps if it is not filled in:
- Click the drop down menu under Datum/Grid and choose “NAD 83- UTM”
- Identify the UTM zone for your map. If you don’t know it, click on your area with this tool to identify which zone your county map falls in.
- The Map Units are in Meters.
- Click ‘Add Layer.’ The program will open a window to confirm the addition of the layer. Click ‘OK.’
- The background maps for other counties can now be added by repeating steps 1-8 before moving on.
- Click ‘Return’ when all background maps are loaded to return to the Layer Manager.
- Note that these maps are stacked on top of one another, and any of the maps that are solid will block viewing layers underneath them. As such, always confirm that the aerial imagery shown in the lowest rows within the Layer Manager.
- Click ‘Apply,’ to add the maps to Office, then ‘Finish’ to complete the import and view the background maps.
- Finally, click on the blue magnifying glass in the Field Maps tab to zoom to the Base Maps Extent. This adjusts the display so that all of the maps added to FieldX.
