struct CoordTspec

Holds the 3d-coordinate tile-set specifications

Documentation

Holds the 3d-coordinate tile-set specifications.

This structure holds information about the 3D coordinate system that is used to represent the tile data.

Parameters:
systemType - (tspSymbol) currently only tspSpheroid
spheroidName - (tspSymbol) currently only tspNad83 or tspWGS84
equatorialRadius - (double) the equatorial radius of the spheroid (meters). This is usually called 'a' in USGS literature.
polarRadius - (double) the polar radius of the spheroid (meters). This is usually called 'b' in the USGS literature.
geotoLVCS - (float[16]) a 4x4 matrix to transform the geocentric coordinate system to a local coordinate system, or lcs. I.e. a point (x,y,z,1) in the geocentric coordinate system is transformed to the lcs by pre-multiplying with this matrix.
lvcstoGeo - (float[16]) the 4x4 inverse matrix of geotoLVCS.
lcsType - (tspSymbol) tspUtmCoordSystem, tspLvcsCoordSystem, tspNone
originLat - (float) the latitude of the origin (degrees).
originLong - (float) the longiture of the origin (degrees).
localUnitsPerMeter - (float) currently only 1.0
componentNames - (tspSymbolArray) currently only {tspX,tspY,tspZ}
componentUnits - (tspSymbol) currently only tspMeters or tspDegrees
