ROIToGeoJSON Task
This task converts geometry-based regions of interest (ROIs) to GeoJSON features.
Example
; Start the application
e = ENVI()
; Open an ROI file
File = Filepath('qb_boulder_roi.xml', Subdir=['data'], $
Root_Dir=e.Root_Dir)
rois = e.OpenROI(File)
; Get the task from the catalog of ENVITasks
task = ENVITask('ROIToGeoJSON')
; Define task inputs
task.Input_ROI = rois[2]
outFile = e.GetTemporaryFilename('.json')
task.Output_GeoJSON_URI = outFile
; Run the task
task.Execute
; Display the result
xdisplayfile, outFile
Syntax
Result = ENVITask('ROIToGeoJSON')
Input properties (Set, Get): INPUT_ROI, OUTPUT_GEOJSON_URI
Output properties (Get only): OUTPUT_GEOJSON
Properties marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.
