The DMC constellation of small satellites provided several images to support the 2006 Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Experiment. DMC is a unique sensor because of its combination of wide swath and high spatial resolution. The data was acquired from UK-DMC at 09:42:53 GMT on the 17th June and consists of three multispectral bands (green, red, near infra-red) with a nominal ground resolution of 32 m. The study area forms a very small part of the whole DMC image, which has a swath width of over 640 km. Other DMC data were obtained from satellites in the constellation operated by Algeria and Nigeria. The NigeriaSat-1 and UKDMC images were taken around the time of the campaign and the AlSAT image a month later. These files have not been geometrically referenced and vary in quality and amount of cloud cover.
As part of the 2006 Field Campaign of the Network for Calibration and Validation of EO data (NCAVEO), an Intergraph Z/I Imaging Digital Mapping Camera (DMC) was used to collect data in 4 spectral bands in the visible and near infrared, at a nominal ground resolution of 65cm. The Chilbolton site was flown over on the 9th June 2006 by the Ordnance Survey, resulting in 84 strips captured over the Area of Interest (2048 x 3072) with 60% overlap along the track. The data was orthorectified to the British National Grid using photogrammetric methods.
The optical data collected by Landmap consist of Advanced Near InfraRed Radiometer type 2 (AVNIR-2), Colour InfraRed (CIR), Disaster Monitoring Constellation (DMC), Landsat 4/5, Landsat 7, Near InfraRed (NIR), SPOT (Earth-Observing Satellites) and Topsat data, along with Mediterranean Landsat imagery and Modern and Historical Aerial Photography. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK, part of which was optical aerial and satellite imagery. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.
