PERSPECTIVES
Digital Terrain Models: GPS or Aerial-Satellite Sensing?

"Both GPS and aerial-satellite sen­sors are used to gen­er­ate data suit­able for cre­at­ing a dig­i­tal ter­rain model (DTM). In the case of GPS, a series of points are mea­sured through tri­an­gu­lat­ing sig­nals orig­i­nat­ing from a series of GPS satel­lites. Alter­na­tively, aerial-satellite plat­forms that include sen­sors, such Lidar, radar or even using pho­togram­me­try tech­niques may also be used to gen­er­ate a DTM. When is it bet­ter to gen­er­ate a DTM from GPS tech­nolo­gies as com­pared to aer­ial or satel­lite sensing?"

Beyond Visualisation: Intelligent City
Planning and Management

3D visualisation models have a variety of applications in geography and urban studies, including site location analysis, emergency facilities planning, design review and marketing. A pressing problem facing many of these models is their general inability to engage the vast majority of their users and the people whose lives they influence in a meaningful and intuitive fashion.

 

Quantifying and Analyzing Farm Sustainability

Researchers at the University of Illinois at Urbana-Champaign have released the Illinois Farm Sustainability Calculator (IFSC), an open-source, spreadsheet-based model capable of quantifying and analyzing various measures of environmental sustainability for any farm in the state of Illinois.

Digital Cities, SDI and the GeoWeb
ron_lake_thumbWhen a domain is relatively new, the terminology is often imprecise, and many different words many be coined and used by different organizations and individuals with none of them realizing that they are talking about essentially the same thing. This is substantially true for the use of Digital City and SDI as applied to urban environments.
REVIEW
Rethinking Maps
thumb-rethinking_maps75Today the discussion surrounding maps and cartography is growing. The Internet is allowing more people in different places to experience map use digitally through a wide variety of devices. This use is creating questions about maps, mapping and cartography. Editors Martin Dodge, Rob Kitchin and Chris Perkins have gathered togather a collection of contributors, each writing about the changing nature of maps, cartography and their use. The book 'Rethinking Maps - New frontiers in cartographic theory' is not only about mapping today, it describes where mapping might be in the future and provides insightful considerations for thinking about the many changes happening in the pursuit of cartography.
INTERVIEW
From Photogrammetry to 3D Digital Earth

thumb_armin_gruen75Photogrammetry continues to evolve and today the study of photogrammetry remains important. Armin Gruen has previously served as Head of the Chair of Photogrammetry at the Institute of Geodesy and Photogrammetry, Federal Institute of Technology (ETH) in Zuerich, Switzerland. V1 Magazine editor Jeff Thurston interviewed him recently to learn about his life long passion of photogrammetry, the beginnings of what would become the CyberCity company and his work as one of the original members of the Board for Digital Earth.
