   @sebastienbourg Thanks for reporting this issue. According to SEDONA-163, Shapefile Reader currently only supports the types marked as `true` below. Geometries that are in other types will be automatically skipped. If you check your log, you should be able to see a number of WARNING log. For POLYGONZ shapefile, I suggest you use GeoPandas to convert it to WKT/WKB.
   
   ```
   	NULL(0, false),
       POINT(1, true),
       POLYLINE(3, true),
       POLYGON(5, true),
       MULTIPOINT(8, true),
       POINTZ(11, false),
       POLYLINEZ(13, false),
       POLYGONZ(15, false),
       MULTIPOINTZ(18, false),
       POINTM(21, false),
       POLYLINEM(23, false),
       POLYGONM(25, false),
       MULTIPOINTM(28, false),
       MULTIPATCH(31, false),
   
   ```
