I am relatively new to GIS.
I need to define small areas (manually draw them out) within a buffer zone around a point. After they are drawn out I need to quantify how much of the buffer zone (1 mile from point) these drawn areas take up in total.
I have a ortho high-res map layer as well as a shapefile from the census. I also have several points geocoded for this project.
Can anyone help with the process of:
- using the edit feature to draw out areas around the geocoded point. I have been able to create polygons but not sure how to create a feature that merges all drawn polygons that I am drawing as one feature.
- seeing how much area these manually drawn areas take up in a buffer zone around the geocoded point.
