Experimental Well-Known Text parser for the Crystal language, compatible with the OGC WKB, PostGIS EWKB and SQL-MM part 3 GIS standards. It's primary goal is to be compatible with spatial databases like PostGIS or SpatiaLite (among others).

Status

Please note that I consider this Shard as a toy to learn about GIS and how to handle binary protocols in Crystal.

If you like it and would like to maintain it, please contact me!
