How to reproject the coordinate system from WGS84 to UTM?
I’m new to ProjNET and NetTopologySuite, I get some points with Lon/Lat in WGS84, and the distance between two points is not with the unit of meter, so I want to reproject the coordinate system from WGS84 to UTM, here is the code but I found that, after reproject the coordinate, the value of distance_in_meter is wrong.
Is there a.NET port of JTS Topology Suite?
A C#/.NET port of JTS Topology Suite, a Java library for GIS operations, (OpenGIS compliant). Learn more… I am looking for a technique for getting accurate distances between two points in the 3857 projection. I believe solutions exist which transform the coordinates to 4326 and compute the distance from
What is the problem with the polygon in NTS?
I am using NTS in my application and I have two line strings which are as follows: Line String 1: LINESTRING (51055.227410858584 52102.041513978584, 51073.39084032347 52096.46568847251, 51183…. What is the problem with the polygon? Getting a *“found non-noded intersection”* exception error
How to generate srid from UTM text-geographic?
You could use the information here to generate a SRID – basically add the zone number to 32600 (in the north) and 32700 in the south. This works if you can use WGS84 as the geographic coordinate reference system.
What is the return value for geography in PostGIS?
All return values from geography calculations are in meters, so our answer is 9125km. Older versions of PostGIS supported very basic calculations over the sphere using the ST_Distance_Spheroid (point, point, measurement) function.
What kind of spatial type does PostGIS use?
PostGIS provides this functionality through the geography type. Oracle attempts to paper over the differences by transparently doing geographic calculations when the SRID is geographic. SQL Server uses two spatial types, “STGeometry” for Cartesian data and “STGeography” for geographics.
