Is there a way I can update the results of my Buffer analysis? I have a roads FeatureClass, and I've built a buffer for it. I will still make edits to the road FeatureClass. Let's say I add a new segment of road, how can I automatically buffer the new segment without creating a new buffer FeatureClass?

I use ArcGIS 10.1

Thank you for your help.

PS: Apparently when using Geomedia if your information changes in your data source, so does the analysis in the workspace. I want to know if ArcMap can do the same.

Is the buffer distance always the same for each new feature, or is it defined within a column in the roads FC? –  artwork21 Sep 23 '13 at 20:08

The buffering tool creates a new output FeatureClass. What you could do is create a model that you run to create a buffer as a new temporary dataset in the in_memory workspace and then append that to your existing buffer FeatureClass. The assumption behind this approach is that you are creating buffers from NEW features and not features you have edited (e.g. extended an existing polyline).

Thank you for your reply. So the answer is practically no. I first thought maybe "Re run" the tool would be the answer or some other way I don't know. But apparently I have to create a model. Thank you both for clearing that out. –  Ligia Sep 24 '13 at 5:57
