I have a spatial dataset with two major columns:
group_ID. The spatial polygons are represented by each
county_name. Some counties share the same
group_ID, while some counties contain more than one
group_ID: i.e., I want to merge polygons with the same
group_ID into one, and split the polygon which contains many
group_ID (randomly or evenly) into sub-polygons with the same number of
group_ID, and assign the
group_ID feature to each split new sub-polygons.
I am very new to QGIS and spatial in python, is there a way to do both at the same time, or just part of that?
