Buffering over a certain distance

IrshadJamal — Wed, 02 Feb 2011 01:22:31 GMT

Dear GISers,

I am trying to figure out how to buffer a feature (River) by certain intervals, (0-50m, 50-100m, 100-250m, 250-500m and greater than 500m)

I am able to use the multiple ring buffer tool in ArcGIS 9.3 to buffer the first 4 criteria, but how do I handle a distance greater than 500m?

Thanks very much.

did you rule out putting in a value that you know would extend beyond the extents of your input layer?...then clip to your extents to limit the excess?

Hi Dan,

Thanks for your kind response. I do have about 13 different input layers that belong to a study area. The objective of the exercise is to assign criteria scores (1-100) depending on distance from the themes.

I guess I could find out the theme with the greatest extent and use that value as a basis for the other themes and then clip out the excess.

Warm regards,
