GISMapTransform

Synopsis

provides a convenient user interface (UI) to the GISMeshProject module.

Input Port

in1	Mesh	A mesh field (any form) that contains data to pass through map transform
in2	Mesh	A mesh field (any form) that contains data to pass through map transform
in3	Mesh	A mesh field (any form) that contains data to pass through map transform
in4	Mesh	A mesh field (any form) that contains data to pass through map transform

Parameters

Map Transform	UIlist	Select required map transformation.
Center of Projection	UIdial	Select 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.

Output Port

Transform	string	The selected transform
GlobalRadius	double	The selected global radius
baseLat	double	The selected base latitude
baseLon	double	The selected base longitude
firstPar	double	The selected first parallel
secondPar	double	The selected second parallel
out1	Mesh	The mesh field resulting from applying the requested map transformation to in1
out2	Mesh	The mesh field resulting from applying the requested map transformation to in2
out3	Mesh	The mesh field resulting from applying the requested map transformation to in3
out4	Mesh	The mesh field resulting from applying the requested map transformation to in4

Description

GISMapTransform provides a convenient user interface (UI) around the GISMeshProject module. It allows up to four independent Mesh data fields containing meshs of data (in (x,y,z)_format) to be processed by the same map transformation request. In this manner, this single macro can be used to perform a consistent map transformation between all of the input ports. For a complete description of the various map transformation, please see GISProjection .

Input

in1

The input must be a field containing any type of mesh data field. The mesh is used as input to a GISMeshProject module. There is no connection between this input port or any of the other input ports in this macro.

in2

The input must be a field containing any type of mesh data field. The mesh is used as input to a GISMeshProject module. There is no connection between this input port or any of the other input ports in this macro.

in3

The input must be a field containing any type of mesh data field. The mesh is used as input to a GISMeshProject module. There is no connection between this input port or any of the other input ports in this macro.

in4

The input must be a field containing any type of mesh data field. The mesh is used as input to a GISMeshProject 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

These widgets are derived from the corresponding input ports on the GISProjection_module. Please See GISProjection for the precise meaning and values for these widgets.

Output Port

Transform
GlobalRadius
baseLat
baseLon
firstPar
secondPar

These output ports are pass-through ports that correspond to the settings on the widgets in the UI panel. This information is made available to the outside world, so the settings can be preserved from one GIS module to another.

out1

This is a Mesh data field containing the results of performing the requested map transformation on input mesh in1.

out2

This is a Mesh data field containing the results of performing the requested map transformation on input mesh in2.

out3

This is a Mesh data field containing the results of performing the requested map transformation on input mesh in3.

out4

This is a Mesh data field containing the results of performing the requested map transformation on input mesh in4.
