Abstract

Landsat 7 imagery was acquired by the Landmap project from Infoterra. Landsat 7 satellite is equipped with an Enhanced Thematic Mapper Plus (ETM+) instrument, developed by Raytheon Santa Barbara Remote Sensing in Santa Barbara, California. Imagery is available for the whole of the UK from 1999 to 2001 at 15m resolution for the panchromatic and 25m resolution for the band 1-3 and 1-7 GeoTiff images. 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. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

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

File Format:
Data availability and file format
Panchromatic images are available in img format, with all others available in GeoTiff and ecw formats. All three formats can be opened in all earth observation image processing software including open/free software such as Erdas ER viewer or Basic ERS & Envisat (A)ATSR and Meris Toolbox (BEAM). img files are raster image files created by ERDAS IMAGINE that contain one or more layers, called bands, which include multiple image tiles that comprise the image, GeoTiff files are TIFF files which have geographic metadata embedded as tags within the TIFF file (which can then be used to position the image in the correct location and geometry on the screen of a geographic information display) and ecw (Enhanced Compression Wavelet) files are compressed images. Data are archived in the directory structure of region/year/format/data for ease of use, metadata are provided with their respective data files.

Introduction

The Landsat Program is one of the longest running programmes for image acquisition from space, first launched in 1972 the program is managed between the U.S. Geological Survey and NASA. Eight satellites have so far been launched, the most recent being Landsat 8, on February 11th, 2013. Landsat satellite imagery offers a unique resource for global change research and applications in agriculture, geology, forestry, regional planning, education, and national security.

Landsat 7 satellite is equipped with an Enhanced Thematic Mapper Plus (ETM+) instrument, developed by Raytheon Santa Barbara Remote Sensing in Santa Barbara, California. The Landsat 7 spacecraft is about 14 feet long (4.3 meters) and 9 feet (2.8 meters) in diameter. It consists of a spacecraft bus, built by Lockheed Martin Missiles and Space in Valley Forge, Pa., and the Enhanced Thematic Mapper Plus (ETM+) instrument. The ETM+ operates over the following spectral bands:

  • Band 1 (Blue): 0.45 to 0.52µm
  • Band 2 (Green): 0.53 to 0.61µm
  • Band 3 (Red): 0.63 to 0.69µm
  • Band 4 (Near infrared): 0.78 to 0.90µm
  • Band 5 (Mid infrared): 1.55 to 1.75µm
  • Band 6 (Thermal infrared): 10.4 to 12.5µm
  • Band 7 (Mid infrared): 2.09 to 2.35µm
  • Band 8 (Panchromatic – False Colour): 0.52 to 0.9µm
Imagery is available for the whole of the UK from 1999 to 2001 at 15m resolution for the panchromatic and 25m resolution for the band 1-3 and 1-7 images.

Landsat 7 imagery was acquired by the Landmap project from Infoterra. 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. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.


Restricted Data Access

The Landsat 7 data are available to UK academics and students. To apply for access, please

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

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.

Abstract
This computation involved: DETAILS NEEDED - COMPUTATION CREATED FOR SATELLITE COMPOSITE. deployed on Landsat 7. Landsat 7 was launched as a continuation of the Landsat programme on 15th April 1999 and is still operational as of July 2014. A three-axis attitude control subsystem stabilizes the satellite and keeps the instrument pointed toward Earth to within 0.05 degrees. The LANDSAT World-Wide-Reference system catalogues the worlds land mass into 57,784 scenes, each 115 miles (183 kilometres) wide by 106 miles (170 kilometres) long. <div property="cedacat:introduction"> <div class="introduction">Introduction</div> <p>Landsat 7 was launched as a continuation of the Landsat programme on 15th April 1999 and is still operational as of July 2014.
