Home » What is a MISR path?
Since the orbits of the Terra platform repeat themselves every 233 revolutions around the Earth, it is natural to name each of these different trajectories or paths. For MISR, the path is the generic name (actually the numeric label) of all orbits that observe the same areas under the same nominal angular conditions. Areas that are close to each other in longitude will be covered by paths with similar numbers. The path number is also included in the file name of MISR products.
The path numbering system uses the Landsat Worldwide Reference System-2 (WRS-2). WRS-2 consists of 233 paths progressing systematically from east to west, and defined such that path 1 crosses the equator at 64.60° west longitude.
