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 Until recently, however, the available large-scale elevation datasets lacked precision and were outdated – some of the most-used data was more than 50 years old.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.
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.
