ArcGIS is a complete platform for data management, visualization and analysis. However, sometimes you need to use data from other platforms, but still want to combine it with spatial data and ArcGIS capabilities. Koop is an open-source Javascript engine that is easily extendable to connect ArcGIS with any API. You can use Insights with data from Microstrategy, or spatial analysis with dynamic data from Salesforce. Using Koop, other platforms become an integrated layer with ArcGIS to build StoryMaps, configure a dashboard, perform analysis or mapping, and share privately or as Open Data. In this session we'll walk through building a new adapter with as little as 30 lines of JavaScript and introduce you to the community of developers building other adapters that you can easily re-use.
