some features are lost when -clean #546
Comments
I'll look into this... thanks for attaching a sample dataset :) |
I see what you mean... I will work on fixing this. Geometry errors like this can be hard to debug and fix, so it might take me a while. |
Many thanks. |
Just for my information, what kind of geometry errors have you noticed? |
In my experience, geometry errors like this are generally related to the limited precision of JavaScript's floating point math operations. The -clean function detects all the places where pairs of line segments intersect each other. When two line segments are almost-but-not-quite parallel, or a vertex of one segment is located almost exactly along the second segment, then it becomes harder to reliably test if the segments intersect. |
Hi. |
Hi,
I have an issue when applying -clean option on some data, I lose some features...
Here the test datas: https://e-nautia.com/fmp2a/disk/public/temp1.zip
