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...

From Traditional Photogrammetry to UAS

Photogrammetry has changed substantially in the past three decades. When Jeff Yates began in the business 32 years ago, he used a projection system known as a Kelsh two-bucket plotter. “That was four generations ago of photogrammetric systems hardware,” he recalls. “From there, we went to the analog stereo plotter. That was the second big...

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...

Cardinal Systems’ Extraterrestrial Photogrammetry

On Earth, photogrammetrists can normally use man-made objects in their frame—such as a road of known width or a curb of known height—as scales. When none is present, they can insert such “ground truth” as needed—for example, by placing onto surveyed locations targets that will be visible in their images. On other planets in our...

State of: Precision Agriculture

One of the fastest growing areas of application for geospatial technologies, precision agriculture is a way to optimize agricultural production through the application of crop information, advanced technologies, and management practices. Precision farmers map in detail variations in soil chemistry, moisture, and other site-specific conditions, use this information to produce “prescription maps,” then use these...
