Sensors. 2.1 On the Ground, In the Air, In Space. 34. 2.2 Satellite Characteristics. 36. 2.3 Pixel Size, and Scale. 39. 2.4 Spectral Resolution.remotely sensed data with spatial resolutions extending from 0.5 to 25,000m the features occurring in an image in terms of the object or type of land Four types of resolutions are defined for the remote sensing systems. • Spatial resolution. • Spectral resolution. • Temporal resolution. • Radiometric High spectral resolution - hyperspectral - Resolution. Importance to Remote Sensing Can be overcome with proper sensor platform type In remote sensing we refer to four types of resolution: spatial, spectral, radiometric and temporal. ➢ Spatial resolution refers to the size of the The specifications of the platform and the sensor determine the resolutions of the remotely sensed data: spatial, spectral, temporal, and radiometric. Resolutions of Remote Sensing. 1. Spatial (what area and how detailed). 2. Spectral (what colors – bands). 3. Temporal (time of day/season/year). NASA has to address these same types of questions as they design remote sensing satellites. NASA engineers have to balance pixel size and resolution with Resolution of a remote-sensing system is of different types. (1). Spectral Resolution. (2). Spatial Resolution. (3). Temporal Resolution NASA's Applied Remote Sensing Training Program. 22. Remote Sensing – Types of Resolution. • Spatial Resolution. – Smallest spatial measurement. After reading this unit, you should be able to: • discuss the basic concepts and importance of image resolution in remote sensing;. • describe the types of In very broad terms, resolution refers to the ability of a remote sensing system to there are clear trade-offs between different forms of resolution.
