Satellite Imagery’s Impact
Above: The highest resolution of commercial satellite imagery is still more than an order of magnitude lower than the highest resolution attainable from aerial platforms. Keystone Aerial Surveys, Inc. developed this digital surface model from 1.75 cm digital imagery taken with a low-altitude flight. The resolution is sufficiently high to enable its use for mapping...
New Markets for Satellite Imagery
In June, the U.S. Department of Commerce, granting a request by DigitalGlobe, gave the company permission to sell its imagery at the best resolutions available from its current constellation. Additionally, six months after its new WorldView-3 satellite is operational, DigitalGlobe will be permitted to sell imagery at a resolution of up to 0.25 meters panchromatic and...
It’s About Time
Australia tech-rebel company Locata is poised to profoundly change the world of positioning, navigation, and timing. In 1994 in Canberra, Australia, accomplished musician and entrepreneur Nunzio Gambale was introduced to a fellow musician, David Small, by Gambale’s cousin who had been giving Small a hand with an interesting experiment. This chance meeting began an amazing partnership in technological development. The scenic capital territory of Australia has its fair...
Satellite Imagery for Precision Agriculture
Precision agriculture consists primarily of using geospatial technologies to map spatial variations in crop and soil conditions and to match inputs—such as water, seed, and fertilizer—to those variations by applying them at variable rates. The link between the spatial variations and the variable rates are zone maps and prescription maps. The former show the difference...
