Abstract

The Disaster Monitoring Constellation (DMC) is a satellite series built by the Surrey Satellite Technology ltd (SSTL) and run by DMC International Imaging (DMCII). The DMC data archive contains data from the first (DMC-6) and second generation (DMC-6-22) UK satellites (which were part of the DMC), having multitemporal coverage for most parts of the UK for each year since 2007. The Landmap project collected the best available DMC images as a single coverage of most of the UK for each year from 2007 to 2010. The resolution provided by the second generation satellites and first generation satellites is 22m and 32m respectively, with data in green, red and Near InfraRed (NIR) bands collected. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC. The DMC is a constellation of small satellites that was formed by national governments and organisations for coordinating satellite imaging campaigns to assess and mitigate natural disasters with more up to date and timely imagery. The DMC programme started by launching Algeria's satellite "AlSat-1" in the year 2002. This first satellite was soon joined by the satellites of the British National Space Centre, Nigeria and Turkey forming the four satellite constellation. Later, China and Spain also became a part of the DMC mission.

Data lineage:

Data collected and prepared by the Landmap team before a copy of the data were obtained by NEODC directly from Landmap.

File Format:
The data are archived in the directory structure of region/year/format/data. The data are available in GeoTiff format (with GeoTiff world files (.tfw) which are data files that are used to geo-reference images to an appropriate projection scheme) and ecw (Enhanced Compression Wavelet) format. Geotiff files are TIFF files which have geographic metadata embedded as tags within the TIFF file. The geographic metadata can then be used to position the image in the correct location and geometry on the screen of a geographic information display. They can be opened by most Geographic Information Systems (GIS) and Image Processors (IP) such as the freely available Basic ERS & Envisat (A)ATSR and Meris Toolbox (BEAM). The ecw (Enhanced Compression Wavelet) files are compressed images and can also be opened in most image viewing/editing software, including open/free software such as Erdas ER viewer

More Information (under review)


Introduction

The Disaster Monitoring Constellation (DMC) is a satellite series built by the Surrey Satellite Technology ltd (SSTL) and run by DMC International Imaging (DMCII). The DMC data archive contains data from the first (DMC-6) and second generation (DMC-6-22) UK satellites (which were part of the DMC), having multitemporal coverage for most parts of the UK for each year since 2007. The Landmap project collected the best available DMC images as a single coverage of most of the UK for each year from 2007 to 2010. The resolution provided by the second generation satellites and first generation satellites is 22m and 32m respectively.

The DMC is a constellation of small satellites that was formed by national governments and organisations for coordinating satellite imaging campaigns to assess and mitigate natural disasters with more up to date and timely imagery. The DMC programme started by launching Algeria's satellite "AlSat-1" in the year 2002. This first satellite was soon joined by the satellites of British National Space Centre, Nigeria and Turkey forming the four satellite constellation. Later, China and Spain also became a part of the DMC mission.

The radiometers onboard have 2 banks of 3 imagers of the following bands and a spatial resolution of up to 22 or 32m:

  • Green: 0.52 to 0.60µm
  • Red: 0.63 to 0.69µm
  • Near InfraRed (NIR): 0.77 to 0.90µm

Data are available in GeoTiff and ecw (Enhanced Compression Wavelet) formats.


Restricted Data Access

The DMC data are available to UK academics and students. To apply for access, please

  • 1) Register as a CEDA user. If you already are a CEDA (or NEODC or BADC) registered user, skip this step. If you have forgotten your CEDA user ID and/or password, please contact the helpdesk at support@ceda.ac.uk.
  • 2) Apply for access to the Landmap data. Application involves the agreement with the Landmap terms of use.

Data availability and file format

The data are archived in the directory structure of region/year/format/data. The data are available in GeoTiff format (with GeoTiff world files (.tfw) which are data files that are used to geo-reference images to an appropriate projection scheme) and ecw (Enhanced Compression Wavelet) format. Geotiff files are TIFF files which have geographic metadata embedded as tags within the TIFF file.

They can be opened by most Geographic Information Systems (GIS) and Image Processors (IP) such as the freely available Basic ERS & Envisat (A)ATSR and Meris Toolbox (BEAM). The ecw (Enhanced Compression Wavelet) files are compressed images and can also be opened in most image viewing/editing software, including open/free software such as Erdas ER viewer.


Software

Basic ERS & Envisat (A) ATSR and Meris Toolbox (BEAM): BEAM is an open-source toolbox and development platform for viewing, analysing and processing of remote sensing raster data. Originally developed to facilitate the utilisation of image data from Envisat's optical instruments, BEAM now supports a growing number of other raster data formats such as GeoTIFF and NetCDF as well as data formats of other Earth Observation (EO) sensors such as Moderate Resolution Imaging Spectroradiometer (MODIS), Advanced Very High Resolution Radiometer (AVHRR), AVNIR, Polarised Radiation Imaging and Spectroscopy Mission (PRISM) and Compact High Resolution Imaging Spectrometer (CHRIS). Various data and algorithms are supported by dedicated extension plug-ins.

Erdas ER viewer, available free of charge, can be used to open raster image formats such as TIFF, GeoTiff, IMG, ECW, ERS, ALG, DAT and many more, and is capable of handling large file sizes.
