Population Pressures Require More Detailed Data

Details: 27 July 2008 | By Matt Ball | 2238

Elevation is a critical component of any earth observation, and elevation data is frequently used for a wide variety of applications. Until recently, however, the available large-scale elevation datasets lacked precision and were outdated – some of the most-used data was more than 50 years old. Intermap Technologies, one of the companies most actively exploring and taking advantage of new opportunities in the elevation data space, has developed a highly accurate statewide elevation dataset for California leading to innovative developments in land use planning and floodplain mapping.

The Public Enterprise Sachsenforst and the Geodata Infrastructure of the Free State Saxony

Details: 25 June 2008 | By Andreas Hergert | 2535

The Free State of Saxony in Germany has been developing a forest management system that has evolved into the Saxon Forest Geographical Information System (FGIS). The system not only supports forestry but it integrates tightly into the wider Saxony Spatial Data Infrastructure (SDI). Both government agencies and citizens can access the system, sharing information and collaborating together. As a state-of-the-art forest and SDI development, this system is now looking to expand its GIS capabilities in other innovative ways.

Measuring Carbon Footprints in U.S. Forests

Details: 08 June 2008 | By Jessica Wyland | 2923

How do we retrace our ecological footprints? Where will the footprints lead? Scientists at the Woods Hole Research Center (WHRC) are tracking carbon footprints across the globe starting with U.S. forests. One ongoing study, using geographic information system (GIS) technology, is measuring the carbon-rich biomass in heavily wooded areas to indicate the effect that deforestation and land use have on rising carbon levels in our atmosphere.
