Earth observation satellites collect data relevant to a wide range of land resource topics and there are a variety of satellite data that are designed for different purposes. Satellite data are collected, transmitted, stored, and analyzed in digital forms. Satellite data have a broad range of spatial, spectral, radiometric, and temporal characteristics. Commonly used terms are spatial, spectral, radiometric, and temporal resolutions. A general indication of advancement of satellite data is that their resolutions are getting higher over time. Satellite can be used alone, to derive new data, and integrated with other geospatial data sources. While most of commercial satellite data can be purchased from data providers, many governmental satellite data can be downloaded without charge from US government websites.
