clipping linear tracks

Hi all

I have an issue when trying to clip linear tracking data with a polygon area of interest. The problem is why in some cases, the tracks I am clipping end up with vertices at all linear intersections which is not what I want, and in some cases, I have tracks ending up with millions of vertices. This is easier to see in the following graphics:

Clipped track:

So, my question is how to stop these additional vertices from being added (or is this something inherent in the geoprocessing algorithm and I have to live with it)

I could of course manually edit these tracks but this will be massively time consuming.

Any ideas would be gratefully received, unfortunately I cannot share this data.

Best regards,

Mark

Have you looked at the pairwise tools? Pairwise Intersect—Help | ArcGIS Desktop I haven't worked with these a ton but I recall them giving different output because they work differently from some of the other analysis tools.

Hi Kory,

Many thanks for the suggestion - alas, this still produces vertices where the lines intersect.

Will keep looking for a solution.

Best wishes,

Mark
