Sensor Characteristics

With seven bands of Multispectral (color) imagery, Landsat 5 Thematic Mapper data provides a wealth of information on ground cover and land use beyond what can be seen with the naked eye and over very large areas.

SIME Region of Coverage

 
Landsat SIME's daily imagery acquisitions cover the area within the circle shown on the map.

Orbital Calendar & Path/Row map

The Landsat system provides global coverage between 81 degrees north latitude and 81 degrees south latitude. Each orbital track is described on the ground by a line, called a "Path", running near N-S. Each numbered Path is divided into uniformly sized scenes, which are numbered "Rows" at fixed latitudes. This system of Paths and Rows is called the World Reference System Path/Row Map. To view this map for Landsat 5, go to the Landsat 5 Path/Row map, which shown the scene centres for each Path/Row location in SIME's Landsat 5 region of coverage.

The orbital calendar for Landsat 5 for the year 2000, which shown the Path flown on each day of the year, is available at Orbital calendar

Image Location

Landsat data is identified by the path and row of the location of the client's Area of Interest. These identifiers are determined using the Landsat path/row map. Landsat digital products are available as: Full scenes that cross row boundaries are to be ordered by path/row and a shift, if required (as percentages in multiples of 10). Each 10% shift is equivalent to 17km southwards. For all other products, the co-ordinates of desired area's upper left (NW) corner or center must be provided. These co-ordinates may be provided in deg:min:sec format or in decimal degrees.
