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 parameters (Set, Get): INPUT_ROI, OUTPUT_GEOJSON_URI

Output parameters (Get only): OUTPUT_GEOJSON

Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.

Input Parameters

INPUT_ROI (required)

Specify the ENVI ROIs to convert to GeoJSON. Only geometry-based ROIs are supported; pixel ROIs are not.

OUTPUT_GEOJSON_URI (optional)

Specify a string with the fully-qualified path and filename for the GeoJSON file.

Output Parameters

OUTPUT_GEOJSON

This is a reference to the output GeoJSON object.
