WorldView-1

WorldView-1 is a high-capacity, panchromatic imaging system featuring true 50 cm resolution imagery. It was launched in September 2007. 

Operating at an altitude of 496 kilometers, WorldView-1 has an average revisit time of 1.7 days and is capable of collecting over one million square kilometers per day of 50 cm imagery.

The satellite is also equipped with state-of-the-art geolocation accuracy capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection.

Application:

  • mapping and updating of topographic and special maps as well as plans up to the scale 0f 1:2000;
  • the creation of digital terrain models accurate to 1-3 m;
  • inventory and control of construction of transport infrastructure as well as oil and gas production;
  • forest management, inventory and forest condition assessment;
  • inventory of agricultural land, creation of land-use planning, precision agriculture;
  • update of topographic base for general construction plans for perspective urban development and territory planning schemes of municipalities;
  • inventory and monitoring of transport, energy and communications.

* - In remote sensing, ground sample distance (GSD) in a digital photo (such as an orthophoto) of the ground from air or space is the distance between pixel centers measured on the ground. For example, in an image with a one-meter GSD, adjacent pixels image locations are 1 meter apart on the ground. GSD is a measure of one limitation to image resolution, that is, the limitation due to sampling: GSD = (ps*h)/f  where ps - size of pixel, m; h - heigth of imaging, m; f - focal length, m.
