ENVIROIToGeoJSONTask

ENVIROIToGeoJSONTask

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
