Landsat etm

The Landsat Enhanced Thematic Mapper (ETM) was introduced with Landsat 7. ETM data cover the visible, near-infrared, shortwave, and thermal infrared spectral bands of the electromagnetic spectrum. The Landsat Project is a joint initiative of the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) Landsat 7 collects data in accordance with the World Wide Reference System 2, which has catalogued the world's land mass into 57,784 scenes, each 183 km wide by 170 km long. The ETM+ produces approximately 3.8 gigabits of data for each scene Landsat ETM. Multispektralbildkombination Für das menschliche Auge sind die unterschiedlichen Merkmale der Erdoberfläche in einem Schwarzweißbild nur schwer zu erkennen. Deshalb ist es hilfreich, drei schwarzweiße Landsatbilder zu einem RGB-Farbbild zu kombinieren. RGB steht für Rot (Kanal 3), Grün (Kanal 2) und Blau (Kanal 1) und beruht auf dem physikalischen Prinzip des additiven. Der US-Satellit Landsat 7 ETM ist der sechste in Betrieb genommene NASA-Erdbeobachtungssatellit seiner Serie (Start von Landsat 6 schlug 1993 fehl). Er ist der letzte dieser Serie von Erdbeobachtungssatelliten, die bis auf das Jahr 1972 zurückgeht. Damit stellt das Landsatsystem die längste durchgehende Beobachtungsreihe der Erdoberfläche

The Landsat 7 ETM+ instrument is designed with the significant exception of the thermal infrared band, where the ground resolution has been improved from 120 to 60 m. The ETM instrument incorporates a new 15 m panchromatic band, as well as a 9-bit analog to digital converter Der Thematic Mapper (TM) ist ein durch die Landsat-4 und -5 Satelliten gestütztes opto-mechanisches System zur Erfassung von Fernerkundungsdaten im Forschungsbereich der Fernerkundung, Enhanced Thematic Mapper (ETM+) die Erweiterung bei Landsat-7 Das Landsat-Programm hat seinen Ursprung in der Zeit der Apollo-Mondlandungsmissionen in den 1960er Jahren, als zum ersten Mal Bilder der Erdoberfläche aus dem Weltraum gemacht wurden. 1965 machte der damalige Direktor der United States Geological Survey (USGS), William Pecora, den Vorschlag, ein Fernerkundungssatelliten-Programm ins Leben zu rufen, um somit Daten über die natürlichen Ressourcen der Erde zu erhalten

Landsat 7 carries the Enhanced Thematic Mapper Plus (ETM+) sensor, an improved version of the Thematic Mapper instruments that were onboard Landsat 4 and Landsat 5. Landsat 7 products are delivered as 8-bit images with 256 grey levels. Descriptions of Landsat 7 band designations and comparisons of all Landsat sensors are available Landsat, Serie amerikanischer Erderkundungssatelliten auf fastpolaren (Inklination i = 99º), MSS, Landsat 6-7: ETM (Enhanced Thematic Mapper). Die Wiederholrate beträgt bei Landsat 1-3 18 Tage, bei Landsat 4-7 durch eine etwas geringere Bahnhöhe 16 Tage. Die operationellen Phasen der einzelnen Landsat-Missionen waren/sind: Landsat 1 23.7.1972-1978 (h = 907 km), Landsat 2 22.1.1975-1983. Band 6 senses thermal (heat) infrared radiation. Landsat can only acquire night scenes in band 6. A TM scene has an Instantaneous Field Of View (IFOV) of 30m x 30m in bands 1-5 and 7 while band 6 has an IFOV of 120m x 120m on the ground Landsat is a satellite imaging program that has been collecting moderate resolution Earth imagery since 1972.

The Landsat 7 ETM+ scenes typically covers 185 x 170 km. A standard full scene is nominally centred on the intersection between a Path and Row (the actual image centre can vary by up to 100m). Each band requires 50MB (uncompressed), and Band 8 requires 200MB (panchromatic band with resolution of 15m opposed to 30m) The Landsat Thematic Mapper (TM) sensor was carried on Landsat 4 and Landsat 5, and created images consisting of six spectral bands with a spatial resolution of 30 meters for Bands 1-5 and 7, and one thermal band (Band 6). The approximate scene size is 170 km north-south and 183 km east-west (106 mi by 114 mi). TM could not resolve individual houses or trees, but it could record areas where.

  1. The Landsat TM, ETM and OLI sensors have a swath width of 185 km and require only 233 paths for complete coverage. MSS and TM scenes share common rows, but in most cases the paths will be different. Because of this difference, MSS scenes are identified using WRS I while TM, ETM and OLI scenes use WRS II path/row designations. The data archive section of the CEO web site uses the WRS II.
  2. The ETM sensor continued the high-resolution Landsat imagery begun with the Thematic Mapper (TM) on Landsats 4 and 5. The ETM consisted of 7 spectral channels (6 with a ground resolution of 30 meters and one (thermal IR) with a ground resolution of 120 meters) plus a panchromatic channel providing a ground resolution of 15 meters. The spacecraft lost contact with ground stations shortly after.

Step 2 Select your data to download in the Data Sets tab. The Datasets tab answers the question: What satellite or aerial imagery are you looking for? The USGS Earth Explorer remote sensing datasets are plentiful: aerial imagery, AVHRR, commercial imagery, digital elevation models, Landsat, LiDAR, MODIS, Radar and more. It depends on the date and time for which Landsat scene you can. On 31 May 2003 the Landsat 7 Enhanced Thematic Mapper (ETM) sensor had a failure of the Scan Line Corrector (SLC). Since that time all Landsat ETM images have had wedge-shaped gaps on both sides of each scene, resulting in approximately 22% data loss Landsat sensors are frequently used to predict forest biomass and carbon storage, mainly because data from the platform are freely downloadable with a long history and moderate spatial resolution [39].
