WorldView-2

WorldView-2 is the first high-resolution 8-band multispectral commercial satellite. It was launched in October 2009. Operating at an altitude of 770 kilometers, WorldView-2 provides 46 cm panchromatic resolution and 1.85 meter multispectral resolution.

WorldView-2 has an average revisit time of 1.1 days and is capable of collecting up to 1 million square kilometers of 8-band imagery per day.

The WorldView-2 system, offers incredible accuracy, agility, capacity and spectral diversity, substantially expanding its imagery product offerings to both commercial and government customers.

 

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;
  • iInventory 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;
  • a wide range of tasks in the field of environmental protection.

* - 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.
