GeoPackageToShapefile Task

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)

Syntax

Result = ENVITask('GeoPackageToShapefile')
