Remote Sensing Platforms and Types

Remote Sensing Platforms and Types

In this article one can see remote sensing platforms and types with a comparison between different types of sensors. The tabular comparison is made between satellite sensor, altitude, life, sensor bands, sensor resolution, revisit frequency, capacity and swath width all in one image. After visiting various websites this data has been compiled for those who are new in the field of GIS and should not have to spend much time gathering it.
