Hello Ideally using ArcGIS Pro, but if not, then using the latest version of ArcMap: I have received a file with numerous multi-part polygons that have been merged to share a single line of an attribute table. I need the centroids for each part of the polygon - not a single centroid in the middle of all of them which will inevitably be inside none of them (so not this: https://support.esri.com/en-us/knowledge-base/how-to-find-the-centroid-between-multiple-polygon-featu-000018271#:~:text=The%20following%20steps%20describe%20how%20to%20find%20the,configure%20the%20following%20settings..%20Specify%20the%20polygon%20layer.) Is there a way to generate centroids for each part of each polygon, or would I need to unmerge them first? Thank you

I've been asked for (for 430 polygons) Latitude of Easternmost edge of site Decimal degrees The four ‘bounding coordinates’ of the site should be its easternmost, southernmost, westernmost and northernmost point. Longitude of Easternmost edge of site Decimal degrees Latitude of Southernmost edge of site Decimal degrees Longitude of Southernmost edge of site Decimal degrees Latitude of Westernmost edge of site Decimal degrees Longitude of Westernmost edge of site Decimal Degrees Latitude of Northernmost edge of site Decimal degrees Longitude of Northernmost edge of site Decimal degrees

That sounds like exactly what I want - I have 430 polygons, so a model sounds like the way to go. As I've never used SQL or models before, can you point me to a 'Dummies guide to models?" link

Thanks but as above, I need points that are part of the polygon, not the points of a container which (given the irregular shapes of my polygons) are not actually located within the shape

Yes, the "maximum N, S, E and W points"

Hi, same reply, but I couldn't figure out how to turn off "assumed answered" I really appreciate your help, and I may have a fundamental misunderstanding, and am happy to be corrected, but it seems that no - it doesn't. If you assume, for the sake of argument, your shape is diamond, it gives you the bottom left coordinate and the top right coordinate as if someone had drawn a square around your shape, and given you only those two points. So it doesn't give all 4 points, and the 2 points it does give are not actually in the polygon?

Hi all I have ARC 10.2.1. I have a shapefile of polygons, and the I need the maximum N / S / E / W points for each polygon (not the centre point) Is there a way to do this? (I can use the tools etc, but have no knowledge of scripts or anything like that, so I would need some pretty basic instructions if that's what's required) (Geometric attributes / extent only gives 2 max/min extents which do not reflect the actual shape of the polygon, not all 4) Thanks
