AsShape
Summary
Converts GeoJSON objects to ArcPy geometry objects. GeoJSON is a geospatial data interchange format for encoding geographic data structures.
Syntax
AsShape (geojson_struct)
Parameter | Explanation | Data Type |
geojson_struct |
The geojson_struct includes type and coordinates. type includes the following strings: Point, LineString, Polygon, MultiPoint, and MultiLineString. | Dictionary |
Data Type | Explanation |
Object |
AsShape returns a geometry object (PointGeometry, Multipoint, Polyline, or Polygon) based on the input GeoJSON object. import arcpy gjPoint = {"type": "Point", "coordinates": [5.0, 5.0]} ptGeometry = arcpy.AsShape(gjPoint) |
Code Sample
Create a PointGeometry object using a GeoJSON object.
import arcpy gjPoint = {"type": "Point", "coordinates": [5.0, 5.0]} ptGeometry = arcpy.AsShape(gjPoint)
Create a Multipoint object using a GeoJSON object.
import arcpy gjMultiPoint = { "type": "MultiPoint", "coordinates": [[5.0, 4.0], [8.0, 7.0]]} multiPoint = arcpy.AsShape(gjMultiPoint)
Create a Polyline object using a GeoJSON object.
import arcpy gjLineString = { "type": "LineString", "coordinates": [[5.0, 4.0], [8.0, 7.0]]} polyLine = arcpy.AsShape(gjLineString)
Create a multipart Polyline object using a GeoJSON object.
import arcpy gjMultiLineString = { "type": "MultiLineString", "coordinates": [ [[5.0, 4.0], [8.0, 7.0]], [[4.0, 5.0], [7.0, 8.0]]]} mpPolyLine = arcpy.AsShape(gjMultiLineString)
Create a Polygon object using a GeoJSON object.
import arcpy gjPolygon = { "type": "Polygon", "coordinates": [ [[10.0, 0.0], [20.0, 0.0], [20.0, 10.0], [10.0, 10.0], [10.0, 0.0]]]} polygon = arcpy.AsShape(gjPolygon)
Create a Polygon object using a GeoJSON object.
import arcpy gjPolygonWithHole = { "type": "Polygon", "coordinates": [ [[10.0, 0.0], [20.0, 0.0], [20.0, 10.0], [10.0, 10.0], [10.0, 0.0]], [[12.0, 2.0], [18.0, 2.0], [18.0, 8.0], [12.0, 8.0], [12.0, 2.0]]]} polygonWithHole = arcpy.AsShape(gjPolygonWithHole)
