Aspose.Gis.SpatialReferencing

Aspose.Gis.SpatialReferencing namespace provides classes for working with spatial references (coordinate reference systems).

Classes

ClassDescription
AxisAn axis describes one dimension of SRS.
BursaWolfParametersClass that contains parameters of Bursa-Wolf formula to transform to another datum.
CompoundSpatialReferenceSystemCompound SRS unites two underlying SRS, none of which can be compound.
EllipsoidEllipsoid represents an ellipsoid, which approximates earth.
GeocentricSpatialReferenceSystemGeocentric SRS is 3 dimensional cartesian SRS with origin at earth center.
GeocentricSpatialReferenceSystemParametersParameters to create geocentric SRS. Parameters have reasonable defaults, so you will have to assign only some of them. If you assign null to any parameter, a default value will be used.
GeographicDatumGeographic datum relates longitude and latitude to particular place on earth.
GeographicSpatialReferenceSystemA Geographic SRS is an SRS that is based on longitude and latitude. A Geographic SRS can be two dimensional or three dimensional. If geographic SRS is three dimensional, then it is actually a compound SRS of two dimensional SRS and vertical SRS.
GeographicSpatialReferenceSystemParametersParameters to create geographic SRS. Parameters have reasonable defaults, so you will have to assign only some of them. If you assign null to any parameter, a default value will be used.
IdentifiableObjectRepresents an object that might have EPSG code and name.
IdentifierRepresents an identifier - a reference to external description of an object. If you create a SRS from WKT, Identifier corresponds to “AUTHORITY” keyword.
LocalDatumIndicates method used for measurements in local spatial reference system.
LocalSpatialReferenceSystemLocal SRS related coordinates to some object, not earth.
PrimeMeridianPrimeMeridian represents a meridian at which longitude is defined to be 0.
ProjectedSpatialReferenceSystemProjected SRS is a result of application a projection to geographic SRS. A projected SRS can be two dimensional or three dimensional. If projected SRS is three dimensional, then it is actually a compound SRS of two dimensional projected SRS and one dimensional vertical SRS.
ProjectedSpatialReferenceSystemParametersParameters to create projected SRS. Some of parameters have defaults. Some parameters have reasonable defaults, so you don’t have to assign only them. If you assign null to those parameters, a default value will be used. ProjectionMethodName and Base don’t have defaults - you have to assign some non null value to this properties.
ProjectionRepresents a projection method with parameters, that transforms (longitude, latitude) to (x, y).
SpatialReferenceSystemSpatial reference system maps coordinates to places on Earth. There are different types of SRS, see Type. What’s more, if type of SRS is Geographic or Projected, SRS can be compound or single, see IsCompound.
SpatialReferenceSystemTransformationSpatial reference system transformation transforms geometries from source spatial reference system to target spatial reference system.
TransformationExceptionTransformation exception is thrown when error occurs during transformation of coordinate or during transformation creation.
UnitRepresent measurement unit.
VerticalDatumIndicates method used for vertical measurements.
VerticalSpatialReferenceSystemVertical SRS is a one dimensional SRS that describes height coordinates.
