The design of this application involves quite a few moving parts. Photo metadata information will be extracted using the Python PIL
module. The extracted information will include geographic coordinates. The coordinate information can then be passed to the Esri World Geocoding service as a reverse geocoding operation to obtain the nearest address to the photo. The coordinate and address information can then be written to a local point feature class using the ArcPy Data Access
module. The photos will also be copied to Dropbox so that they can be accessed through a web-based application. The final step in this chapter will be to upload the local file geodatabase to ArcGIS Online where it will be configured alongside the Dropbox photos to display property locations and photos that can be shared in a web application:
Let's get started building the application.
