Introduction to data type
Satellite data with low and medium resolution are characterized by spatial resolution at about 1 km and hundreds of meters, respectively. These data are obtained solely in a multispectral mode including visible and infrared part of the optical spectrum. Due to the wide swath of these satellites, the data with daily or a-few-day frequency are guaranteed.
The data are suitable for mapping in the scale of about 1:1,000,000.
