I have a point shape file which contains corner points of buildings or houses. How can I create house foot prints for all the corner points in the layer at once. If I use minimum bounding rectangle, it created one big polygon around all the points, I want to have separate minimum bounding rectangle for each set of points in the point layer..!!. I hope you all understood the issue.
Do the points have an attribute that ties together the points of a specific building? For example, all corners of first building have value 1, points from second building have value 2, etc.
Hi Darren,
No these point does not contain any attributes,They are just points with xyz.
Unless the buildings are obviously spread out (i.e. distinct clusters of points), there may not be a way to automatically connect the dots.
You could try running Points to Line which may connect most of the points if they are stored in order. If they do turn out to be in order, and each building has exactly 4 corners, you may be able to script the rectangles in Python (although there is some question whether the points are guaranteed to be read in order).
So how do you know the corners for each build?

Since you have the lidar, I wonder if there if anything in this blog that might help
https://community.esri.com/people/GTaylor-esristaff/blog/2016/06/24/3d-workshop-feature-extraction-t... I think this is written for Pro.
If not, Darren's suggestions might be the best semi automated process. (Points to lines...Gen cleaning up by editing) or, again, if the points are in order....points for each building in groups, you could add a field and give a unique value for each building, then loop thru the groups to make the buildings, either with points to lines or points to polygon.
Do a web search on extracting building footprints and there are many threads on this topic (although most are aerial photos or older tech, not lidar)
