  • Radar Ortho Suite
    Technical Specifications Radar Ortho Suite The Radar Ortho Suite includes rigorous and rational function models developed to compensate for distortions and produce orthorectified radar images. Distortions caused by the platform (position, velocity, and orientation), the sensor (orientation, integration time, and field of view) the Earth (geoid, ellipsoid, and relief), and the projection (ellipsoid and cartographic) are all taken into account using these models. The models reflect the physical reality of the complete viewing geometry and correct all distortions generated during the image formation. Module Prerequisites The Radar Ortho Suite is an add-on to Geomatica. It requires Geomatica Core or Geomatica Prime as a pre-requisite. Supported Radar Formats The Radar Ortho Suite supports the following radar sensors. • ASAR o ASAR 1B format • COSMO-SkyMed o Level 0 (RAW) o Level 1A (SCS) o Level 1B (DGM) • ERS 1/2(CEOS) o ERS CD provides different levels of processing. We recommend the georeferenced level for images produced in Canada and the PRI level produced by ESA. • Gaofen-3 (GF3) o Level 1A SLC data with an associated RPC model for the following observation modes: . Spotlight [SL] . Ultra-fine stripmap [UFS] . Fine stripmap [FSI] . Wide fine stripmap [FSII] . Quad-pol stripmap [QPSI] . Wide quad-pol stripmap [QPSII] . Wave [WAV] • Huanjing (HJ-1C) o 1C Level 2 format • JERS1 (LGSOWG) o JERS-1 CD provides different levels of processing. We recommend that you use a georeferenced level or equivalent for highest accuracy. OrthoEngine only works for descending order images. • KOMPSAT-5 o L1A SCS_U: Single Look Complex Slant Un-balanced o L1A SCS_B: Single Look Complex Slant Balanced o L1B DSM_U: Detected, Slant Range, Multilook Un-equalized o L1B DSM_U: Detected, Slant Range, Multilook o L1B DGM_B: Detected, Ground projected, Multilook Balanced The information in this document is subject to change without notice and should not be construed as a commitment by PCI Geomatics.

Because the information is captured digitally, computers can be used to process, store, analyze, and distribute the data in a systematic manner. And because the same sensor on the same platform is gathering images for all points on the planet’s surface, these measurements are globally consistent

Bloemer and Quattrochi: Introduction to Remote Sensing: Remote Sensing Satellites EROS A & B EROS (Earth Remote Observation System) A1 was launched in December 2000 as the first constellation of eight high-resolution imaging satellites to be launched between year 2001 and 2005. EROS satellites are high performance, low cost, light, and agile and have been designed for low earth orbit (LEO). The satellites are owned and operated by ImageSat International. This Cyprus-based company was established in 1997 by a consortium of leading satellite, sensor and information management companies and information producers around the world. In February 2001, a couple of months after EROS A1 was launched, ImageSat decided to forgo the production and launch of its planned EROS A2 satellite.
