One of the most interesting developments in geographic information systems over the past two years has been a renewed dedication to making 3D maps easier to make and view. ArcGIS Pro represents the most significant development in terms of 3D GIS content creation, but thanks to WebGL, there has also been an additional leap forward in online 3D mapping: Cesium, StoryMaps, and the “new” Google Earth – which is entirely in-browser. Given these very recent advances, are we watching the beginning of a shift toward 3D mapping as a delivery system for global information? If so, can a 3D globe do for 3D models what 2D interactive maps have done for digitized historic maps (i.e., assist with discovery)? At Monday's Munch & Mull, we'll discuss where we are with 3D GIS and what this may mean for the field of information science.
