RuntimeError: Object: CreateObject cannot create geometry from inputs

DevonCanady — Tue, 31 Oct 2017 15:11:18 GMT

I cannot seem to create a geometry using a list of coordinates. I'm parsing these coordinates from a JSON object, which I have successfully tested, but from the documentation it seems this should work once I have a double to input. Here is another similar example.

import arcpy, json
jsonObj = """{
"points": [
    {
      "Y": 35.631453769591765,
      "X": -97.586939334869385
    },
    {
      "Y": 35.628907432142576,
      "X": -97.587132453918457
    },
    {
      "Y": 35.627703997864323,
      "X": -97.589900493621826
    },
    {
      "Y": 35.630180611005642,
      "X": -97.590758800506592
    },
    {
      "Y": 35.630302695584653,
      "X": -97.5909948348999
    },
    {
      "Y": 35.631453769591765,
      "X": -97.586939334869385
    }
],
"spatialReference": {
    "wkid": 4326
}
}"""
dictionary = json.loads(jsonObj)
#the Polygon method fails whether I input a list of Points or PointGeometries
coordsList = []
for items in dictionary["points"]:
   pt = arcpy.Point(items["X"], items["Y"])
   coordsList.append(arcpy.PointGeometry(pt, arcpy.SpatialReference(4326)))

geometry = arcpy.Polygon(coordsList, arcpy.SpatialReference(4326)) #fails here
# arcpy.CopyFeatures_management(geometry, FILEPATH)

You are close, try this:

import arcpy, json

jsonObj = """{
"points": [
    {
      "Y": 35.631453769591765,
      "X": -97.586939334869385
    },
    {
      "Y": 35.628907432142576,
      "X": -97.587132453918457
    },
    {
      "Y": 35.627703997864323,
      "X": -97.589900493621826
    },
    {
      "Y": 35.630180611005642,
      "X": -97.590758800506592
    },
    {
      "Y": 35.630302695584653,
      "X": -97.5909948348999

    {
      "Y": 35.631453769591765,
      "X": -97.586939334869385
    }
  ],
  "spatialReference": {
    "wkid": 4326
  }
}"""

dictionary = json.loads(jsonObj)
coordsList = arcpy.Array()
for items in dictionary["points"]:
    pt = arcpy.Point(items["X"], items["Y"])
    coordsList.append(pt)
    
geometry = arcpy.Polygon(coordsList, arcpy.SpatialReference(4326))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
