Version SLIM – 6 - Disaster Monitoring Constellation (DMC) Software


The Disaster Monitoring Constellation (DMC) consists of Algerian, Nigerian, Turkish, British and Chinese remote sensing satellites constructed by Surrey Satellite Technology Ltd (SSTL) and operated by DMC International Imaging.  The main aim of this constellation is disaster relief under the International Charter for Space and Major Disasters. DMC Earth imagery is used for a variety of civil applications by a variety of governments. Idle imaging capacity is utilized for commercial purposes.

Out of these UK-DMC, Nigeriasat-1, and Alsat-1 have been retired. New Satellite have been launched under DMC-2 constellation named as Nigeriasat-2 and UK-DMC2. The primary imaging payload on-board these satellites is the SLIM-6 class imager built by SSTL UK. The design of the SLIM-6 class imagers  provides a 3 spectral bands. 

The spectral band selection for the DMC spacecrafts was deliberately chosen to be equivalent to that of the SPOT HRV multi-spectral imagers and bands 2, 3 and 4 of the LANDSAT Thematic Mapper.

Previous satellites have used these bands in a multitude of application areas from land-use  classification, crop yield assessments and vegetation stress monitoring, to burn scar mapping, urban growth modeling and insect threat assessment. However, the unique combination of high-swath, medium-spatial resolution and high-temporal resolution of the DMC opens up a new range of application areas: The system is found to be ideal for monitoring the development of fire risk over very short temporal scales using a combination of scene-derived vegetation indices, classification maps and external thermal data.
