I need to do a field mapping and i already have the grid (points). I need to put this points in my phone and use my android device to find this points in the field. I won't have any internet connection.
I did this mapping and I succeed on it. To find the points on the field, I created a grid on Qgis and exported the data to an excel table. Then, in the field and with the coordinates, I used the app 'GPS Status' to find the points. The program doesn't show a real-time map like google earth, what can slow down a bit the work, but it's really possible to do a mapping with this method.
