Some of them are contiguous so when I create the buffers there are multiple overlaps. I am trying to derive a division of the buffer so that every park has got just one reasonable (cut) buffer area. Any idea? cheers</P></BODY></HTML> Wed, 13 Jun 2018 21:25:23 GMT https://community.esri.com/t5/data-management-questions/buffer-division/m-p/297691#M17067 NicolasClerici_ 2018-06-13T21:25:23Z Re: BUFFER DIVISION https://community.esri.com/t5/data-management-questions/buffer-division/m-p/297692#M17068 <HTML><HEAD></HEAD><BODY><P>did you try to union or intersect the overlapping buffers…?</P><P>The information that appears in the tables might be what you are looking for</P></BODY></HTML> Wed, 13 Jun 2018 22:04:04 GMT https://community.esri.com/t5/data-management-questions/buffer-division/m-p/297692#M17068 DanPatterson_Retired 2018-06-13T22:04:04Z Re: BUFFER DIVISION https://community.esri.com/t5/data-management-questions/buffer-division/m-p/297693#M17069 <HTML><HEAD></HEAD><BODY><P>The problem is dividing the overlapping portions of the buffers in a a reasonable way. It is a hard geometrical problem. One possible way is to connect intersecting buffer in the dissolved buffer perimeter and get the points (blue in the image), get the intesecting points in the periphery of the parks (red points) and connect a line (with I don't know which instruction) to find a way to cut the buffers (see red lines in the image).
