AgConvertZonesToShapefile Task
This task converts an ENVIAgZones object to a shapefile.
This task requires a separate license for the ENVI Crop Science Module; contact your sales representative for more information.
Example
; Start the application
e = ENVI()
; Open a DEM file
File = Filepath('FieldDEM.dat', $
Subdir=['data','crop_science'], $
Root_Dir=e.Root_Dir)
Raster = e.OpenRaster(File)
; Create management zones
Task = ENVITask('AgCreateZones')
Task.INPUT_RASTER = Raster
Task.MINIMUM_AREA = 2023
Task.NUMBER_OF_APPLICATION_CATEGORIES = 4
Task.Execute
; Convert the zones object to a shapefile
shapefileTask = ENVITask('AgConvertZonesToShapefile')
shapefileTask.INPUT_ZONES = Task.OUTPUT_ZONES
shapefileTask.Execute
Syntax
Result = ENVITask('AgConvertZonesToShapefile')
