I have a country borderline KML polygon (one polygon), and I would like to split it in two regions (two polygons).
Let's say, we have German borders in KML, and I would like to split it into East and West Germany, following some regions borderlines. Or split Belgium into two regions. Or Ukraine in Russian and the rest. Or Cyprus in Greek and Turk part etc...
At least, split the polygon in two, then manually adjust the boundaries of each region, if not possible to split by a region polygon.
For Windows, I downloaded QGIS, an I have also Google Earth. I would like to create a custom MyMap (Google My Maps) based on the resulting two polygons.
Say I take Ukraine as a sample. Found the KML here, now, I have to split it in two, following the administrative divisions of some regions. As result, there should be only two polygons from one polygon.
We have the regions of Ukraine, but not really clear how to split the one country's polygon in two.
