when i finished selecting the training dataset, the geometry vector show 0 features.why?does it influence the classification process?
for exzample.the water calss vector ,it shows 0 features in the red part.
you can double click on the vector containers to see if they contain polygons. Maybe your digitized shapes were put into the wrong container. To make sure the correct vector container is used when you digitize do the following:
- create empty containers with this menu, give reasonable names
- Open the layer manager and mark the folder ‘vector data’
- If you now select one of the digitizing tools (e.g. ), you are asked by SNAP each time, which class will be digitized.
- Mark the “vector data” folder again if this window doesn’t pop up.
