I want to continue to develop our new map application for Azure Cosmos DB. So far, we can run a custom spatial query in Cosmos DB and display the results on a map. I want my users to create a polygon on map and search for data under this polygon. If you are familiar with Zillow, that is how their application lets you look for houses to buy or rent. You select an area, and Zillow application displays all available houses or rental under the area you draw. It is extremely useful and user-friendly search.
