DIN 18714-8 − Requirements to Image Quality

Abstract

Photogrammetry and remote sensing provide procedures for deriving geometric and thematic information from image data. A variety of aircraft and space-based sensors are available to capture image data. According to the applications of German remote sensing and photogrammetry users DIN 18740 (DIN = German ISO regulations) defines this standard and specifies the quality requirements on optical remote sensing data. Due to the possibilities of absolute geometric and radiometric calibration digital sensors provide new promising opportunities to create value added products like Digital Elevation Models, land-use maps etc. Such cameras combine the high geometric quality with the radiometric standards of earth observation systems. The determination of the quality of remote sensing data can in principle be distinguished by (spectral) radiometric and geometric aspects. The standard contains different metrics for accuracy issues (spectral, radiometric and geometric accuracy ) and for performance parameters like SNR, MTF . Image artifacts are another topic of the described standard. The paper gives an overview of the current debate and the possibility of standardization.
