# This is a script that I use to convert geojson to | |
# features in a file gdb | |
# Step 1. Use the REST page of an ArcGIS Map Service to | |
# get the esri json results of the data you want. | |
# Step 2. I used my EsriJSON to GeoJSON app to convert | |
# the results to geojson. http://esritogeo.herokuapp.com/ | |
# Step 3. In ArcMap, use the python window to create a | |
# python dictionary of your geojson. | |
# Step4. Use the following script to convert that geojson | |
# into featureclasses and then merge them. | |
arcpy.env.workspace = r'C:\WorkSpace\target.gdb' | |
# I'm going to save my features to a list for merge later | |
items = [] | |

# Refer to AsShape docs | |
# http://help.arcgis.com/en/arcgisdesktop/10.0/help/000v/000v00000153000000.htm | |
# AsShape only creates a geometry object, so it's up to you | |
# to use the AddField/Calculate field tools if you want to get the | |
# attribute data across. | |
geom = arcpy.AsShape(g["geometry"]) | |
# Save an id I'll use to calculate my field | |
my_id = str(g["properties"]["ID_FIELD"]) | |

# If someone knows of a more efficient way to do this, I'd love to hear about it. | |
# This script isn't exactly a speed demon. |
