I have a geometry question using
Fiona and polygons shapefiles with big data(over 700000 features any polygon shapefile).
I want to find the difference between two polygons using shapely (or maybe geopandas?) and I have read this post, I want the difference calculate only in the polygons segments(lines) and not the polygon geometry.
for example if I use code from the post with add more lines the final export difference is a polygon layer,I want the line layer to show me the differences between two polygons.
with the light blue line is the difference.
that because I think is more fast the difference calculator to create lines from polygons.
