The GetGeoJSON function method returns GeoJSON code that contains bounding box information. Specifically, the GeoJSON code consists of a FeatureCollection of Feature types. See the Bounding Boxes Background topic for details.
This method is part of ENVI Deep Learning, which requires a separate license and installation.
Example
See the example for ENVIBoundingBox.
Syntax
Result = ENVIBoundingBoxSet.GetGeoJSON([, ERROR=value])
Return Value
This function method returns GeoJSON code consisting of a FeatureCollection of Feature types. See the Bounding Boxes Background topic for details.
Arguments
None
Keywords
ERROR (optional)
Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.
When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.
See the Manage Errors topic in ENVI Help for more information on error handling.
EXTENT (optional)
Set this keyword to a two-element array with the x and y dimensions of the image used for labeling. Any bounding boxes that lie beyond these boundaries will be clipped. If you do not specify this keyword, no clipping will occur.
The x and y dimensions always start with 0. Here is one way to ensure zero-based dimensions:
EXTENT=[raster.NCOLUMNS-1, raster.NROWS-1]
