I have a line shapefile and a polygon shapefile. I would like to add a field to the line shapefile that specifies which polygons each line feature crosses (comma-separated ID's or another field, for example), and another field that is the count of polygons. Doing the inverse for the polygon layer would also be insightful (how many and which lines intersect each polygon).
Is there an easy way of doing this in ArcGIS Desktop?
