Create points with uniform distance

GISLearner — Fri, 11 Feb 2022 18:59:13 GMT

I want to create points that are 400 meters apart (both horizontally and vertically) inside a polygon. The polygons are huge so I'm looking for a process that will automatically do that (nothing manual). How to do so in ArcGIS Pro?

Create Fishnet (Data Management)—ArcGIS Pro | Documentation

create a polygon/polyline grid with label points. You probably just want the label points, but you can also convert the fishnet to vertices and remove the duplicates if needed.

It is probably the easiest

I have some tools on github for the slightly more adventurous

You could create a line feature class inside your polygon. If your lines need to be 400 meters apart, use the copy parallel function to get that distance right. Then use the densify too to create vertices every 400 meters along the lines. Then use the feature vertices to points tool to create your points.

I'm not exactly clear on what you mean by vertically and horizontally.

vertically and horizontally. a grid pattern like the label points from fishnet or their vertices

Does this help? Sounds like what you are trying down through step 3.

Would you have any idea why Create Fishnet fails for me? I get the error message: ERROR 000224: Cannot insert features

Also, using the tool Mesh Points from your github, I get the below error. Do you have any idea what I'm missing?

should raise that error, try saving the output to a shorter path.

You are running the tool from the toolbox installed in a path with no spaces? from inside Pro.

Both issues suggest access to arcpy issues and/or path problems to the local file geodatabase
