You can select only the features that you would like buffered, and then execute the tool. Be sure to use the dropdown to select the input feature. The selection will be honored, and only these features will be buffered.
thanks for replying,JS.
So when I select two adjacent polygons and buffer them with OUTSIDE ONLY. I end up with two buffer strips along the shared edge.
Is there a way to leave the shared edge un-buffered?
(To make this less confusing, what I want to achieve is to decide which of the many polygons contain a given location point, after the polygons are buffered. The problem is that after buffering, there is a overlapping region along the interfaces between adjacent polygons. This region is not desired.)
Hope I made myself clearer this time.
The answer is no. But if you have an Advanced license you could follow up the buffer with the Erase tool using the same input selected polygons and end up with what you want (since you only want outside buffers anyway).
I realized you wont get what you want, since you want the shared boundary projected outside of the polygons in a tangent direction to cut off the outside buffer. Only way to do that is to isolate the shared edge somehow and extend it outward to cut with a knowledge of which side the polygons fell on. Not sure how to do that. I have wanted that ability too, but never figured out how to do it.
The Polygon to Line tool could conceivably do part of this and keep track of which polygon is on which side of the share boundary line, but I am not sure how to extend the line the buffer distance and then cut and remove the unwanted portions with the line.
Am I missing the point? There was no diagram so maybe I am.
Why not dissolve on the selected features before buffering? Then the adjacent boundaries will not be buffered.
Are the adjacent polygons not touching? In that case there are other tools that can jump the gap in the Cartographic Toolset.
eg AggregatePolygons Tool
Thanks for joining in.
For my purpose it is essential to maintain the defining boundary for each polygon in the feature. As every polygon has a unique ID in the attribute table, I feel dissolve will compromise this unique identity, as it is a tool to 'aggregate' features. Am I right?
