I am seeking the distance from a point on a linestring, along the linestring ('downstream' from the point) to each and every point of intersection between the linestring and a polygon layer. I would then be processing the results to find the shortest distance to each polygon along the linestring. | |
| Apr 18, 2019 at 7:27 | comment | added | geozelot | are you looking for the (minimum) distance between a linestring (river) and a polygon (site) (if they intersect, distance is 0)? or the distance to the intersection between them, along the linestring (from the start point)? or even the distance along the linestring to the point where a polygon is closest to it? | |

| Apr 17, 2019 at 18:08 | comment | added | ImpactGIS | Thanks for getting back Pieter. I had viewed several solutions all of which appeared to indicate that the distances had to be to points. I was hoping that it may be possible to find the distances to intersections with polygons, so though I would put the question out there. | |
