Fundamentally, temporal data of any type are about dynamic measurement of some system, writes Erik Shepard. In the case of spatiotemporal data, they're about dynamic measurement of a spatial system.
A modern video wall used in a purpose-built application is something to behold. Whether to control a network of high-speed trains or manage an infrastructure of security cameras, today's video wall does it all.
Recognizing the great redevelopment and economic-development potential provided by bringing light rail to downtown Mesa, Ariz., the Mesa City Council directed the planning staff to initiate a plan that includes innovative visualization techniques.
Google Earth, with its high-resolution satellite images, 3-D buildings and road-network data layers, offers a spatial geo-context that's richer in information than ever before for presenting users' own spatial information draped over the Google Earth 3-D globe.
Nigel Waters entered GIS A into a search engine to see what turned up. He then continued until he reached the letter Z. The results proved quite interesting.
Joseph Berry describes a statistical framework for organizing the spatial-statistics toolbox into commonly understood statistical concepts and procedures. But first he clarifies the differences between spatial analysis and statistics.
Continued expansion of BIM from its origins in detailed design and engineering has introduced new users—particularly in the traditional geotechnology space—to the value of infrastructure modeling, which extends the benefits of BIM to a broader set of stakeholders by increasing productivity, reducing costs and enabling better-informed decisions.
Not long ago, geographic visualizations were the domain of specialty companies and software. But now most of the larger geotechnology software companies include built-in visualization packages of their own—created inhouse or permanently added by purchasing visualization companies and their products.
In simpler times, GIS and design worlds were limited to 2-D. It was basic, but it did its job, and everyone was content. But times no longer are as simple, and, with progress, the selection of available "Ds" has proliferated.
