Ryan Briones, City of Chicago
This talk will describe the development and implementation of WindyGrid, an online geographic information system, that presents a unified view of City of Chicago operations to improve agency coordination, incident monitoring and response, and to identify trends. In lieu of reviewing numerous and disparate reports, WindyGrid gives key personnel access to 911 and 311 service calls, asset locations, building information, tweets, and other critical information in one place. To enable this, data from siloed City source systems are regularly ETLed into MongoDB. The City’s implementation of MongoDB has been architected to support multiple shards along with three tiers to allow for expanding query access and redundancy.
