I also sometimes forget tools I have added myself into OpenJUMP ;-)So, here is the result of the "difference" between your two layers (computation time > 1h).I replaced the legacy "difference" operator of the erase tool by a method of the new overlayng package https://locationtech.github.io/jts/j
Funny, I have made the feature request and certainly tested and used that tool
myself some 5 years ago 😊

Hi Michaël,
I had not noticed the erase tool but I am happy to know that it exists.
I reduced the precision to 8 decimal places and just discarded the invalid
geometries. However, I get still a similar error
found non-noded intersection between LINESTRING ( 130.83397613647227
-0.01215176729437
Jukka,Indeed, I have added a tool which does exacly what you describe in Tools > Edit Geometry > Erase a layer from a mask, but unfortunately, it suffers from the same robustness problem. It should also be possible from Tools > Analysis > Geometry Functions... (Difference) after transforming one
Hi,
Sorry, I knew that Overlay worked and meant really the Polygon overlay.
I have seen the non-noded intersection exceptions even before. They stop the
whole process and I have been thinking that from users perspective it might be
good to have an option to skip the errors and get at least some
Jukka,I could successfully run overlay, but not polygon overlay.I think there maybe a solution with JTS snaprounding code, but there is no easyway to use it from OpenJUMP (to my knowledge, node-lines is the only plugin to use a snap-rounding approach, but for a reason, I could not use it with a v
