Issue with EWKT

[Ossi]

What is wrong with ToString() method with DBGeometry (ExtendendWkt)?

Code: Select all

> var geom = Devart.Data.PostgreSql.Entity.Spatials.PgSqlExtendedWktSpatialServices.CreateGeometry("LINESTRING(50027.21876 19769.808585,50030.39452 19797.435555,50035.47266 19821.66406,50039.70704 19836.53906,50045.3164 19853.115235,50057.17188 19880.7441475,50067.86328 19900.7207125,50074.10546 19910.921865,50088.82032 19931.748055,50097.28516 19942.375,50116.76172 19963.2011725,50134.01562 19978.5039075)");

//geometry object is created and all is good.
Console.Out.WriteLine(geom.AsText());

Thank you for your report. We will investigate the issue and notify you.

1. Please use "SRID=0;LINESTRING([...]" instead of "LINESTRING([...]" to fix the issue with ToString().
EWKT = SRID + WKT

2. IsValid doesn't work with WKT / EWKT / WKB.
