Comments
Does your input shape file consist of points?

curse boundary points.shp --output myboundary.shp produces an empty
shapefile with no records.
curse density points.shp --output D:\Temp\myhexagons.shp --edge 100
always ends up returning the following error:

I've played around with the --edge and --count settings, and also run the
command on various point shapefiles, and LAS files, including a point
shapefile generated with the make_shapes.py script.
Is anyone able to get outputs with recent versions of GDAL, or on Windows?
Or maybe I've missed a something basic..

Something must have rotted. This code hasn't been used in this form for quite a while. |
This has really rotted. I took a stab at it and couldn't get it working in 15 minutes of futzing. I would try to use PDAL directly to do this nowadays, as that's where this code has migrated to.

Yes, I tried a shapefile generated from a LAS file, a Python generated one, and a couple more point shapefiles I had to hand all with the same result. I also tried converting to web mercator in case that was an issue (and as used at https://gist.github.com/tmcw/7436261).
Thanks @hobu for investigating and the reply. As far as I can tell the A shame this project is now deprecated - the |
Ignore comment above, the hexagons are available as described at https://pdal.io/en/stable/workshop/exercises/analysis/density/density.html
