[pdal] [filters] Using Crop with a WKT polygon

[GUIMMARA, Sébastien (External)]

Bingo, that was it. I had to duplicate the first point to close the polygon.

Thanks very much,
Sébastien

It doesn't look like the polygon is closed. Does it work if you repeat the first point at the end?

Hello,

I am trying to filter out a dataset using the crop filter, but it produces a PDAL error :

filters.crop : Invalid polygon specification. Must be valid GeoJSON/WKT.

Here is the exact WKT Polygon used in the pipeline :

POLYGON ((110.45675742602 57.4257091225738, 81.1178752491955 28.9292918387268, 106.89682854952 19.694115466231, 143.30641446642 42.4948934905654))

However, when I try to create a geometry from this WKT into GDAL/OGR, the geometry is correct.

Is there something I am missing ?

Sébastien
