Just starting to get an understanding of the power of JOSM. Can I ask for help with JOSM in this forum?
How can I go about making a filter for a river’s shoreline?
I’ve tried
water AND river
but that just provided the river’s centre line
then I tried the key approach
"type" = "multipolygon" AND "water" = "river" AND "name" = "Grand River"
which provided nothing
Any suggestions?
