Description
GISMapInvTransform provides a convenient user interface around the GISMeshInvProject module. It allows up to four independent mesh data fields containing meshes of data (in (x, y, z) format) to be processed by the same inverse map transformation request. In this manner, this single macro can be used to perform a consistent inverse map transformation between all of the input ports. For a complete description of the various inverse map transformation, please see GISInverseProj .
Input Ports
in, in2, in3, in4
The input must be a field containing a mesh data field containing projection world coordinates. The mesh is used as input to a GISMeshInvProject module. There is no connection between this input port or any of the other input ports in this macro.
Parameters
Map Transform
Center of Projection: Latitude and Longitude
Global Radius
Conic Projection Parallels: First and Second
Longitude Offset
These widgets are derived from the corresponding input ports on the GISInverseProj module. See GISInverseProj for the precise meaning and values for these widgets.
Output Ports
out
This is a mesh data field containing the results of performing the requested inverse map transformation on input mesh in, in2, in3, and in4 respectively. The output data field is in (longitude, latitude, altitude) format, and the longitude is in 0 o to 360 o format. Use GISLonConvert to convert to standard East-West longitude format.
