Exercise 04 - Upload the Points to your GPS device

Please note that you need to work with a GPS model supported by GeoAgro GIS and  make sure that it's properly connected.


  1. Conntect to your GPS: 
    Click on the ‘Connect to GPS Device' buttonGPS Module. Automatically, GeoAgro GIS will detect if your GPS device is connected

  2. After connecting to the GPS, click on the Upload Objects to GPS Device GPS Module button. GeoAgro GIS will inform that points are being loaded to your GPS device, as in the figure below
