  • As part of the Centre for Ecology and Hydrology Land Cover 2007 Pilot Project, a reconnaissance survey was undertaken on 12th May 2006 in a 60 x 60 km area (bounded by Ordnance Survey National Grid Reference X = 400000 to 460000, Y = 095000 to 155000) which included the Network for Calibration and Validation in Earth Observation (NCAVEO) test site. A recording tablet device was used for acquiring ground data for sample points in the defined area. The dataset consists of an ESRI shape file of point data, containing all the points recorded on a tablet device. Each point has a British National Grid X and Y co-ordinate and a class code. The dataset has not been checked or edited yet and a few of the records will be erroneous. The most obvious errors will be two or more points with identical locations but different codes, the final code will be the correct one. Some of the points for Salisbury Plain lie just outside the test area boundaries. A key to abbreviations used for field recording is also included and a list of thematic land cover classes and their codes to aid field reconnaissance, as used for Land Cover Map 2000.

  • This dataset contains level 2 vector formatted data derived from the Centre of Ecology and Hydrology's (CEH) Land Cover Map 2000 (LCM2000) data for the Harwood Forest, UK, NCAVEO calibration/validation (cal/val) test site. The NERC funded Network for Calibration and Validation of EO (NCAVEO) campaign was designed to illustrate and explain the processes involved in cal/val of earth observation data.

  • The reflectance spectra of the spring barley of field Brockley, near Chilbolton was collected as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign. This dataset compromises the data which was collected on the 15th June. Measurements were also taken on the 18th at this location, the dataset record for which is available through linked documentation. Measurements were recorded using an ASD N4406 FieldSpec Pro, measurements having been taken at 5 flags within the field. After the exclusion of noisy bands, the spectra contains 1926 bands, covering the wavelengths 350-1354 nm, 1409-1811 nm and 1952-2496 nm. For further information on the processing of the raw data please see the dataset's metadata pdf in linked documentation. Please note that all raw spectra files collected during the NCAVEO campaign with ASD N4406 have incorrect dates. The laptop computer used with the ASD had the month accidently set to JULY instead of June. The DAY of month and TIME (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are marked with the correct 15-18th June 2006 dates.

  • This dataset contains 25m resolution raster formatted data derived from the Centre of Ecology and Hydrology's (CEH) Land Cover Map 2000 (LCM2000) data for the Barton Bendish, Norfolk, UK, NCAVEO calibration/validation (cal/val) test site. The NERC funded Network for Calibration and Validation of EO (NCAVEO) campaign was designed to illustrate and explain the processes involved in cal/val of earth observation data.

  • This dataset compromises data collected by the Compact High Resolution Imaging Spectrometer (CHRIS) over Chilbolton, 17th June 2006, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data were collected in Mode 1, which has 34 metre pixel size and 62 spectral bands between 411 nm and 997 nm, giving a ground resolution of 34 metres. Surrey Satellite Technology Ltd is the owner of all data directly resulting from in-flight operation of the CHRIS instrument flown on- board the ESA PROBA spacecraft. All publications on the CHRIS instrument or data obtained from the CHRIS development and/or operation should therefore make explicit reference to Surrey Satellite Technology Ltd, the CHRIS instrument and the ESA PROBA mission. The L3b Directory contains data created by Ted Milton from the L1b, after having been destriped and registered to the OS grid. For more information on the structure and format of the data please see the associated metadata PDF for the dataset in linked documentation.

  • This dataset consists of the reflectance spectra which was collected on the 16th-17th June 2006 from three artificial targets deployed at the Chilbolton Facility for Atmospheric and Radio Research (CFARR), as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Experiment. The reflectance data were acquired using an ASD FieldSpec Pro fitted with a contact probe. For further details on each of the data files please see the dataset's metadata document in linked documentation.

  • This dataset includes reflectance spectra of Winter wheat collected from Rickyard field, near Chilbolton, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data was collected on the 18th June, using an ASD N4406 instrument. For information on the data's processing please see the metadata PDF in linked documentation. Please note that all raw spectra files collected during the NCAVEO campaign (labelled ***R_ASD0606**.***) have incorrect dates, indicating them to have been collected in July rather than June. The day of month and time (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are also marked with the correct 15-18th June 2006 dates.

  • This dataset includes reflectance spectra of Winter oats collected from Fairpiece field, near Chilbolton, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data was collected on the 18th June, using an ASD N4406 instrument. For information on the data's processing please see the metadata PDF in linked documentation. Please note that all raw spectra files collected during the NCAVEO campaign (labelled ***R_ASD0606**.***) have incorrect dates, indicating them to have been collected in July rather than June. The day of month and time (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are also marked with the correct 15-18th June 2006 dates.

  • A satellite image taken by the LANDSAT 7 Enhanced Thematic Mapper Plus (ETM+) on the 12th May 2001 (source: Univ Maryland GLCF) has been resized to the study area of the 2006 Field Campaign of the Network for Calibration and Validation of EO data (NCAVEO) in Chilbolton. The image has been exported as geotiff using bands 4,5, and 3 as RGB and its projection converted from UTM to the British National Grid, cell size 28.5m x 28.5m. A image from the Landsat 5 Thematic Mapper has also been resized to the study area (see link to this data's record in linked documentation).

  • This dataset contains 25m resolution raster formatted data derived from the Centre of Ecology and Hydrology's (CEH) Land Cover Map 2000 (LCM2000) data for the Chilbolton, Hampshire, UK, NCAVEO calibration/validation (cal/val) test site. The NERC funded Network for Calibration and Validation of EO (NCAVEO) campaign was designed to illustrate and explain the processes involved in cal/val of earth observation data.
