Enable option to remove segments from clip #3

Open maptastik opened 3 years ago

maptastik commented 3 years ago

The current workflow has the user draw an area around the closure which is used to clip the trail segments. They are then combined into a single MultiLineString geometry.

There may occur a situation where an open greenway trail segment intersects a closed one. It is very difficult to draw an area around the closed greenway trail without picking up some portion of the open one.

What I suggest is that between the clip step and the dissolve step, the user have the opportunity to remove any segments that they would prefer not be included in the closure.

I think what might need to happen here is that the clip and dissolve steps be separated. A step would be inserted between the clip and dissolve during which the user can remove dangles segments. Once they're done, they can dissolve the remaining features into a single MultiLineString.
