Combine layers, merge and export flatten fields as csv about mapshaper HOT 2 CLOSED

The clip command does not transfer attribute data from the clipping shapes to the target shapes (it sounds like this is what you want to do). You can try the -union command, which takes two target layers and combines them into a single output layer, while retaining attributes from both layers. After running -union, you would use -filter to retain only those shapes that have attributes from both of the input layers. Try running -union target=PLU_0,communes in the web UI console and inspect the result... that may put you on the right track.

@mbloch great thanks this is working as expected !

mapshaper -i communes.shp -i PLU_0.json \
    -union target=PLU_0,communes \
    -filter 'partition != null' \
    -o PLU_0.shp
