Landsat 7, launched on April 15, 1999, is the latest satellite of the Landsat program. Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud free images.

Your challenge is to identify where each of the (mainly) Landsat images below is located. Hints are given. When you have made your guesses, click here for the answers.
Landsat Data Continuity Mission
Landsat has provided the science community with an important archive of land feature observations. Plans are underway for the next generation of land-observation systems.
LANDSAT
Landsat, the U.S. land remote sensing satellite system, began as an experimental program conducted by the National Aeronautics and Space Administration (NASA).
Landsat TM - Landsat Thematic Mapper. Earth observation satellite with seven bands at 30m spatial resolution (TWS).
Layer - Distinct map theme. Usually a separate GIS file (TWS).
Landsat
A series of satellites that produce images of the earth. The Landsat remote sensing satellite program was developed by NASA (National Aeronautics and Space Administration). Landsat data are provided in .BIL (band interleaved by line) or .

LANDSAT TM
Landsat TM is more advanced multispectral scanner than the MSS system. The spectral resolution encompasses seven bands that range from visible blue to thermal infrared. Included is a Mid Infrared (MIR) band.
Landsat is a system of satellites which scan the earth at a variety of wavelengths. The satellites return information that can be used to inventory and analyze a variety of natural and human resources.
Landsat HSL Composite from Panchromatic Band
A couple of articles ago I outlined how to access Geogratis Landsat 7 data and to combine bands 1, 2 and 5 ( or any three bands between 1 and 7) to produce a 30m true-color RGB composite.
Landsats 1,2, and 3 were decommissioned by 1983. Data acquired during these missions is archived according to their location in the Worldwide Reference System (WRS), which designates each 103 minute orbit within the 18 day orbital cycle as a path, ...

Satellite imagery such as LANDSAT TM and SPOT provide multispectral images of the Earth, some containing seven or more bands.
It was anticipated that analysis of Landsat satellite imagery would be a key ingredient for identifying detailed impacts from the disturbed, abandoned lands. However, an interesting turn of events made the project much more difficult than expected.
Landsat satellites have a Thematic-Mapper (tm) sensor that produces images in many spectral regions, e.g., in the visible range, in the near-infrared, in the mid-infrared, and in the thermal infrared.

Based on Landsat images using ERDAS and vegetation maps, researchers recorded 13 habitats used by wolves in the study site to estimate their total area. They were also able to show potential habitats for wolves.

In 1978, two years after the conference, he started a new career at the USGS headquarters in Reston, Virginia. Snyder's formulas were used to produce maps from the Landsat 4 satellite launched the summer of 1982.
However, given the strategic focus of most assessments, a 30-meter grid-cell size is typically used for modeling. This is consistent with readily available remote-sensing data sources, such as Landsat, ...
