The document discusses building a GIS SaaS app using MongoDB to provide tools for GIS departments to quickly deploy web maps. The solution indexes GIS points and layers from third party web map services in MongoDB databases to enable fast keyword auto-suggestion and creation of databases on the fly. The app utilizes technologies like MongoDB, JSON.NET, and ASP.NET MVC with only a few lines of code needed for caching and search functionality.
