# 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.

Basic example of taking an output from our server and putting it on a map. As leaflet allows you to add geoJSON directly, we convert it from esri's JSON format to a more standard one.
