WorldView-1 satellite
WorldView-1, launched on the 18th of September 2007, is the first of DigitalGlobe’s next-generation satellites – the most agile satellites ever flown commercially. The high capacity, panchromatic imaging system features half-meter resolution imagery. Alongside with DigitalGlobe, such companies as Ball Aerospace, Eastman Kodak, ITT Industries and BAE systems took part in the WorldView-1’s development.

Operating at an altitude of 496 km, WorldView-1 has an average revisit time of 1,7 days and can collect over one million sq km per day of half-meter 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.

Products
Basic – Basic products are designed for customers with advanced image processing capabilities. These imagery products, when combined with supplied attitude, ephemeris, and camera model information, are suitable for advanced photogrammetric processing (for example, orthorectification). Each unique image in a Basic Product is processed individually; seamlines will be visible in products requiring multiple images to cover the area of interest.

Standard – Standard Imagery products are suitable for users requiring modest absolute accuracy and/or large area coverage. Users of Standard Imagery products usually possess enough image processing tools and knowledge to manipulate and exploit the imagery for a wide variety of applications.

Orthorectified – Ortho Ready Standard Stereo Imagery products are suitable for customers with a high level of image expertise and software that is capable of ingesting, processing and/or displaying stereo imagery. They are typically used to create Digital Elevation Models (DEMs) or for 3D feature extraction. Customers ordering stereo products who require a small area of interest (AOI) should order the Ortho Ready Standard Stereo Product while customers requiring large area coverage should opt for the Basic Stereo Product.

Basic Stereo Pair – Basic Stereo Pair Imagery products are suitable for customers with a high level of image expertise and who have software that is capable of ingesting, processing, and/or displaying stereo imagery. Basic Stereo Pair Imagery products are typically used to create Digital Elevation Models (DEMs) or for three-dimensional feature extraction. Basic Stereo Pair Imagery products are comprised of one or more pairs of Basic Images with 100% overlap over the customer’s Area of Interest (AOI). Stereo mates are collected on the same satellite orbit and with specific look angles in order to attain imagery appropriate for stereo viewing.
Applications:
  • Creation and update of maps and plans;
  • Creation of DTMs;
  • Engineering survey for construction works of oil and gas facilities;
  • Inventory of forests and forest management;
  • Monitoring of the crops’ state, yield forecasting;
  • Creation of maps for urban planning purposes;
  • Emergency monitoring;
  • Researches.
