NonGeoreferencedProjection Class
Represents a non-georeferenced projection.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECore assembly)
Syntax
public class NonGeoreferencedProjection : ProjectionRemarks
A non-georeferenced projection is needed when you want to construct a non-georeferenced Crs. There is one predefined Crs.NonGeoreferenced, whose length unit is meter. If you want to construct another such Crs with some other length unit, you must give it a new instance of the NonGeoreferencedProjection, and an arbitrary GeodeticDatum.
You cannot convert coordinates from or to a non-georeferenced Crs. The main use is when you have some geodata expressed in an unknown Crs. If you use the same non-georeferenced Crs for your DataSet and in your View, you can at least look at the geodata. But you cannot locate it relative to other geodata.
A non-georeferenced Crs can also be used for a View showing a vertical profile.
