I have a shapefile with a number of roughly parallel lines in it, and I want to calculate the spacing between these lines using a number of transects across the map.
How should I go about this? I have a bit of experience writing
arcpy scripts, so would be happy to write some code to do this, I just can't quite work out where to start. My best guess would be to draw the transect as a line, somehow create points where the transect line intersects with any other lines, and then calculate the average distance between the points. Does this seem like a sensible approach? If not, what would you suggest?
Update: I need to be able to do this scriptably (from a Python script using ArcPy), which means I won't have access to functions that are only available from toolbar buttons.
