I'm using mapshapers web interface and it looks like I should be able to collapse two layers with
$ help merge-layers Command -merge-layers merge multiple layers into as few layers as possible Options force merge layers with inconsistent data fields name= rename the edited layer(s) target= layer(s) to target (comma-sep. list)
target= attribute isn't working:
$ merge-layers target=bayarea_county,california_places_clipped [merge-layers] Use the target= option to specify multiple layers for merging
I tried putting the list in quotes and got:
$ merge-layers target='"bayarea_county","california_places_clipped"' Missing target: "bayarea_county","california_places_clipped" Available layers:  bayarea_county  california_place_clipped
How do I use
merge-layers in the web interface?
