the shape_file is freespace.zip
Hi,
I can't test the script because some files with the shapefile are missing (.shx, .dbf and .prj files)
Cheers,
Patrick

Sorry, all in this zip. freespace_allinone.zip e
Hi,
I tested with GAMA 1.8.2 and we have the same issue... but I am not sure that it is possible to fix this issue as the skeletonization depends on the triangulation: the differences are due to rounding problems in the floats (slight difference in the coordinates). There is not much we can do about it.
Note that if we define a not null value for the tolerances of triangulation and of clipping, the results are similar in all cases: skeletons <- (skeletonize(last(geoshape ),0.1,0.1));
Cheers,
Patrick

I think that there is nothing we can do automatically here. The arguments to skeletonize
are largely enough to cover this error. I'm closing the issue then, but feel free to open a new one in https://github.com/gama-platform/gama2/issues
Describe the bug 1.8.1, with the same geometry, use skeletonize to this geometry,but the result is different when changing the world shape.
To Reproduce Steps to reproduce the behavior:
Expected behavior when I change the shape (500-->1000 ),the skeletonize result should be same.
