Hello list, Does anyone know of a way to set the numeric precision on a Geometry.ExportToWKT() call ? For the SRS, we are using EPSG:4326 (WGS-84) so the multipolygon coordinates are in latitude/longitude, and most of the coordinate strings seem to carry 15 digits past the decimal point !! For our needs, 7 or 8 digits would be sufficient, so this seems wasteful, especially when the string is stored in a database. I examined the OGR documentation but I don't see any variation of ExportToWKT nor any other means of setting the numeric precision.
I estimate using 7 digits of precision instead of 15 could reduce total storage by about 40%. I realize I could post-process the string produced by ExportToWKT() to reduce all coordinates to the desired precision. But did I miss anything in OGR capabilities ? BTW we are using GDAL/OGR 1.8.0 with C# bindings. Jay Jennings GeoEye, Inc.
