Remote sensing acquires and interprets small or large-scale data about the Earth from a distance. Using a wide range of spatial, spectral, temporal, and radiometric scales remote sensing is a large and diverse field for which this Handbook will be the key research reference. Illustrated throughout, an essential resource for the analysis of remotely sensed data, The SAGE Handbook of Remote Sensing provides researchers with a definitive statement of the core concepts and methodologies in the discipline.
Chapter 10: Coarse Spatial Resolution Optical Sensors
Coarse Spatial Resolution Optical Sensors
coarse resolution remote sensing, AVHRR, MODIS, VIIRS.
Previous chapters have discussed remote sensing imaging systems with a pixel dimension measured in meters. In this chapter, we move to coarser systems, where resolution is typically measured in hundreds of meters to kilometers. Coarse resolution sensors are therefore defined here as those with spatial resolutions between 250 m and 5 km. Until recently these were also referred to as ‘moderate’ resolution systems, but this latter term is now used to refer to the Landsat-class of sensors. This chapter focuses solely on land remote sensing, although it is recognized that coarse resolution sensors are also widely used for the study of oceans and atmosphere.
