I am trying to use the Landscape Vector Overlay function in the LecoS plugin to calculate the amount of various proportions of land cover types (using an ordinary landscape raster) within buffer polygons around individual points (i.e., Landscape Proportions).
When I try to run this I get the following error:
An error has occurred while executing Python code: AttributeError: 'NoneType' object has no attribute 'GetFeatureCount'
I have little to no Python experience so I'm hoping my issue does not involve coding. However, I have not installed anything in Python (because I don't know how) and I realize that might be involved.
I am using QGIS 3.4
I am a pretty basic QGIS user.
I have researched several other options but always end up at a dead end. The LecoS plugin seems like it is designed specifically for what I am trying to accomplish.
