Aspose.Gis.SpatialReferencing

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

Classes

Class Description
Axis An axis describes one dimension of SRS.
BursaWolfParameters Class that contains parameters of Bursa-Wolf formula to transform to another datum.
CompoundSpatialReferenceSystem Compound SRS unites two underlying SRS, none of which can be compound.
Ellipsoid Ellipsoid represents an ellipsoid, which approximates earth.
GeocentricSpatialReferenceSystem Geocentric SRS is 3 dimensional cartesian SRS with origin at earth center.
GeocentricSpatialReferenceSystemParameters Parameters 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.
GeographicDatum Geographic datum relates longitude and latitude to particular place on earth.
GeographicSpatialReferenceSystem A 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.
GeographicSpatialReferenceSystemParameters Parameters 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.
IdentifiableObject Represents an object that might have EPSG code and name.
Identifier Represents an identifier - a reference to external description of an object. If you create a SRS from WKT, Identifier corresponds to “AUTHORITY” keyword.
LocalDatum Indicates method used for measurements in local spatial reference system.
LocalSpatialReferenceSystem Local SRS related coordinates to some object, not earth.
PrimeMeridian PrimeMeridian represents a meridian at which longitude is defined to be 0.
ProjectedSpatialReferenceSystem Projected 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.
ProjectedSpatialReferenceSystemParameters Parameters 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.
Projection Represents a projection method with parameters, that transforms (longitude, latitude) to (x, y).
SpatialReferenceSystem Spatial 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.
SpatialReferenceSystemTransformation Spatial reference system transformation transforms geometries from source spatial reference system to target spatial reference system.
TransformationException Transformation exception is thrown when error occurs during transformation of coordinate or during transformation creation.
Unit Represent measurement unit.
VerticalDatum Indicates method used for vertical measurements.
VerticalSpatialReferenceSystem Vertical SRS is a one dimensional SRS that describes height coordinates.
