]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. |
Enumeration
| Enumeration | Description |
|---|---|
| AxisDirection | Axis direction defines direction at which axis is pointing. |
| GeocentricAxisesOrder | Represents order of axises in geocentric SRS. |
| GeographicAxisesOrder | Represents order of axises in geographic SRS. |
| ParameterType | Determines type of parameter in Projection. |
| ProjectedAxisesOrder | Represents order of axises in geographic SRS. |
| SpatialReferenceSystemType | Represents type of spatial reference system. |
