The document discusses the increasing use of JSON and GeoJSON data formats for sharing geographic information across different platforms and devices. It provides examples of how GeoJSON can be used to represent points, lines, and polygons. It also mentions querying Cloudant databases from ArcGIS Online and suggests that GIS capabilities are becoming more widely available through common data standards and APIs.
