GISMapInvTransform

Synopsis

MapInvTransform provides a convenient user interface to the GISMeshInvProject module.

Input Port

in, in2, in3, in4

Mesh

A mesh field (any form) that contains data to pass through an inverse map transform.

Parameters

Map Transform	UIlist	Select required map transformation.
Center of Projection	UIdial	elect center of map transformation using a separate latitude and longitude dial.
Global Radius	UIslider	Select the global radius to use for the map transform in meters.
Conic Projection	UIdial	Select the first and second parallels to use parallels for conic map transforms.
Longitude Offset	UIdial	The offset to apply to the projection terminator.

Output Port

out, out2, out3, out4

Mesh+Group

The mesh field that results from applying the requested inverse map transformation to its respective input port; that is in, in2, in3 , in4 .

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

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 Port

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.
