LANDSAT 7 satellite is equipped with Enhanced Thematic Mapper Plus (ETM+), the successor of TM. The observation bands are essentially the same seven bands as TM, and the newly added panchromatic band 8, with a high resolution of 15m was added Landsat 7 ist ein am 15. April 1999 gestarteter Erdbeobachtungssatellit der US-amerikanischen Luft- und Raumfahrtbehörde NASA. Der Satellit ist die siebte Ausführung in der Reihe der Landsat -Satelliten. Er ist mit dem multispektralen Sensor ETM+ ausgestattet, dessen Auflösung seit 2003 wegen eines Mechanikproblems stark eingeschränkt ist 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) Newly acquired Landsat 7 ETM+ SLC-off images with less than 20 percent cloud cover are automatically processed and made available for immediate download, while all remaining Landsat 7 ETM+ scenes can be processed upon request. Once the requested scenes are processed, an email notification is sent to the customer with instructions for downloading

Landsat 7 ETM+ SLC-off data refers to all Landsat 7 images collected after May 31, 2003, when the Scan Line Corrector (SLC) failed. These products have data gaps, but are still useful and maintain the same radiometric and geometric corrections as data collected prior to the SLC failure 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 7 was designed to last for five years, and has the capacity to collect and transmit up to 532 images per day. It is in a polar, sun-synchronous orbit, meaning it scans across the entire Earth's surface. With an altitude of 705 km, it takes 232 orbits, or 16 days, to do so If you have Landsat-7 ETM+ then you are likely to encounter striping caused by the failure of the scan line corrector (SLC) in 2003. The SLC failure introduced major striping in ETM+ imagery. So what can we do about this (using ENVI)? I have tested three approaches to solve the problem

The ETM+ produces approximately 3.8 gigabits of data for each scene The ETM+ adds a 60 m resolution thermal band, replacing the 120 m band on ETM/TM (band Number 6). ETM+ data therefore cover the visible, Near Infra-Red (NIR), shortwave, and Thermal Infra-Red (TIR) spectral bands of the electromagnetic spectrum.

Search, browse, and order capability for most of these datasets will be migrated to USGS systems in the near future. Landsat-7 ETM + pixels were considered cloudy if they were labeled as cloudy in either the ACCA or the decision tree cloud masks. This ensured a generous cloud definition (Roy et al., 2010) but meant that cloud-free pixels were sometimes flagged as cloudy and discarded. Similarly, a generous Landsat-8 OLI cloud pixel definition was used and OLI pixels were considered cloudy if they were. Common Landsat Band Combinations Here are some common RGB band combinations (color composites): 3,2,1 RGB This color composite is as close to true color that we can get with a Landsat ETM image. It is also useful for studying aquatic habitats. The downside of this set of bands is that they tend to produce a hazy image. 4,3,2, RGB This has similar qualities to the image with bands 3,2,1 however.

Landsat7_ETM_Plus_C1. Landsat 7 Enhanced Thematic Mapper Plus (ETM+) Collection 1 V1 . Abstract: The Landsat Enhanced Thematic Mapper Plus (ETM+) is a sensor carried onboard the Landsat 7 satellite and has acquired images of the Earth nearly continuously since July 1999, with a 16-day repeat cycle. Landsat ETM+ image data consist of eight spectral bands (band designations), with a spatial. The Landsat-5 TM and Landsat-7 ETM + SR products, derived from the on-demand processing Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS), require periodic evaluation to check the data consistency. Two evaluation approaches are presented in this paper. The first approach used the Aerosol Robotic Network (AERONET) data set for the period 2000 to 2013 over 489 sites with 3600. The Landsat 7 ETM+ SLC-Off composite product is generated by replacing the missing data of a primary SLC-Off scene with pixel values derived from one or more co-registered, histogram-matched fill scenes(s). Figure 3. Histogram matching technique failed due to cloud. If the images chosen to generate the composite product contain transient data such as clouds, snow cover or fires, the histogram. The data used by the researchers came from the Landsat satellites and covered the 10-year period from 1978-1988. The latest mission in the Landsat series - Landsat 7 - is part of NASA's Earth Science Enterprise (ESE) and is being built to continue the flow of global change information to users worldwide

The low crown closure (11-40%) class was not classified successfully in Landsat 7 ETM image due to small area coverage (2.1 ha, 0.03% of the landscape).
