ENVIGeoPackageToShapefileTask

This task converts GeoPackage vector files to Shapefile format.

Example


; Start the application
e = ENVI()
 
; Define input file
file = Filepath('simple_sewer_features.gpkg', $
  SUBDIR=['data','geopackage'], ROOT_DIR=e.Root_Dir)
outDir = envi.GetTemporaryFileName('')
vecFeatures = ['s_manhole']
 
; Get the task from the catalog of ENVITasks
Task = ENVITask('GeoPackageToShapefile')
 
; Convert to shapefile
Task.INPUT_URI = file
Task.VECTOR_FEATURES = vecFeatures
Task.Execute
 
; Get the output shapefiles
outputShapefiles = Task.OUTPUT_URI
 
; Open and display shapefiles
view = e.GetView()
FOREACH shapefile, outputShapefiles DO $
  vector = e.OpenVector(shapefile)
  layer = view.CreateLayer(vector)
