Buffer Tool - blocky results - arc to chord distances

Discussion created by Mick_C on Apr 27, 2011
Hi,

Im using the "Buffer" geoprocessing tool to generate geodesic buffers around points (ArcMap 10). I'm buffering 200 metre distances (so fairly small).

The problem is that I get really ugly, blocky buffer polygons that have about 30 metres between points giving arc to chord differences of around 1 metre. See attached image.

Using the Buffer Wizard gives far nicer results (around 5 metres between points), however these are not geodesic.

Is it possible to specify the distance between points somehow? I would prefer them to be around 1 - 2 metres. Is there a setting that drives this, such as the precision of the coordinate system, or an environment setting?

Thanks,
-Mick
