GPS

If your tablet or other device has GPS capabilities then the map can track your location. Use the

button on the right edge of the screen to control this. When you click this button the system will zoom to and highlight your location on the map.

GPS Status
For more details select "GPS Status" from the main menu. This will display a screen showing additional details such as error messages and the uncertainty of your current location.

Datum Correction
By default, Diamond Maps assumes your GPS is broadcasting WGS84 Lat/Lon coordiantes. This is the case with most GPS devices. However, some GPS devices broadcast NAD83 coordinates. This is usually the case if you are using a higher precision device that uses RTK correction. If this is the case, go to the GPS Status item on the menu and change the source coordinates to NAD83. The correction amounts to about a 3ft shift for most of North America.

Status Color
When the GPS is in ON the background color of the button will indicate the status. Green indicates that the GPS has a fix on you with an uncertainty of less than 200 meters. Red indicates no fix.

Uncertainty
A translucent yellow circle will be shown surrounding your location indicating the uncertainty of the GPS fix. The smaller the circle the more precisely your location is known.

Import GPS Data
On a related note, if you have a GPS device that you have used to collect data points you might be able to import that data into the map. See Import GPX.

"User Denied Loation"
If you get the error message 'User Denied Location' that indicates a permissions issue. click here for troubleshooting instructions.

Marking Points With GPS
See Draw New Features for instructions on how to get the most from your GPS/GNSS device when marking points on the map.

Moving Existing Points To Align With GPS Location
If you have some existing features on your map that were marked by hand and you now want to use a GPS to correct their location, see Move To GPS option on Feature Form's Action Menu.
