Hi I think this is a relativly simple question.

ArcMap v9.2.

I have a lot of line data in a shape file that i need to split by a a number of polygons in another shape file. What is the best way to do this?

What I want to end up with is a list of lines in a shapefile that fall into each of the polygons.

Thanks

Sam

Hi Sol,

This doesn't do what i require. Clip just trims the lines by the outermost extent of the polygon.

What I want to do is split the lines where the polygons cross the lines. Whats the right tool?

Thanks

Use the Intersect Geoprocessing tool to achieve what you want.  It will discover the intersections between features from the inputs. This can be useful to discover polygon overlap and line intersections (as points or lines).

I have tried intersect and it works on some of the lines but not all?!

there are still lines that cross polygons that havent been split - why woudl this be?
