| Feb 6, 2023 at 22:46 | comment | added | Vince | Then you've got an NP problem on your hands, repeatedly buffering, then removing the intersected area, and testing if it's within some tolerance, using increasing and decreasing distances until you meet your criteria, or hit a maximum of attempts and report failure. | |
| Feb 6, 2023 at 21:34 | comment | added | Colin Guilfoyle | @FelixIP thanks for suggestion - similar issue but not quite what I need. | |
| Feb 6, 2023 at 21:33 | comment | added | Colin Guilfoyle | @Vince with an erase/difference/intersect I cant guarantee the area covered by the buffer will be e.g. 1 km2 since the amount of unsuitable habitat will vary point by point. I dont want the buffer to be a specified radius but a specified area (when unsuitable habitat is accounted for). | |
| Feb 6, 2023 at 21:30 | comment | added | Colin Guilfoyle | @Hornbydd apologies, will try to come up with images. Essentially the buffer shape would be determined by the amount of unsuitable habitat in area around the point - since I want the area covered by the buffer to be fixed, the buffer would grow until it reached that size, depending on the extent of unsuitable habitat close to the points. | |

title as statement
