Exercise 02 - Mark your spots

In this exercise, you will mark some locations that you´d like to visit in your farm

1. Make sure the Soils layer is turned on to use soil map units for selecting field visit locations.
   
   
   
2. Make the layer 'GPS Points' Active by clicking on it:
   
   
   
3. Click on the Edit layer objects panel, and select the Add New Object tool.
   
   Enter some sample locations by double clicking on the map area for each point.
   
   
   
4. Assign an identifier to each point in the "GPS points" layer. Go to the "GPS points" layer and select all objects by using the Select by rectangle tool.
