LocalCoordinateSystemSetter
Tags all features with the local coordinate system defined by the specified parameters. It does not reproject features, or otherwise modify their geometry.
You should use this transformer if you know the feature belongs to a certain local coordinate system, but it is not tagged. This can happen if the feature is read from a format that does not store coordinate system information.
Parameters
Choose the local projection from the drop-down list based on whether preservation of distances or areas will be more important during subsequent reprojections. Choices are:
- AZMED (Lambert Azimuthal Equidistant)
- AZMEA (Lambert Azimuthal Equal Area)
Choose the units of the features that will be entering the transformer.
Specify the coordinate system of the origin point. The created local coordinate system will be based on the datum of the origin coordinate system.
Specify the point that corresponds to 0,0 for the features that will be entering the transformer. Origin points within 0.5 degree of the North or South Pole will be rejected.
Usage Notes
Local coordinate systems have the following limitation:
- Z is not considered, so areas or distances are best preserved for geometry at an ellipsoid height of 0 meters.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
