Hi Erwan, there are two issues why I can't use H2GIS. *Issue 1: * the license - GPL 3 is not an option for us
*Issue 2: * We are using a binary format which is different to WKB and we don't want to make huge workarounds, which allows us to convert our binary format to a WKB because that's an unnecessary overhead for us which brings us no benefit. In addition our binary format supports more geometry types which are necessary for our application. Am Mittwoch, 4.
