The spatial expression of an uncertainty for the quality assessment of the digital elevation models
Popis výsledku v původním jazyce
Digital elevation models (DEM) are models that approximate a topographical surface. These models will contain both random and systematic errors that create uncertainty, or unreliability, in elevation measurements. Uncertainty can be defined as a lack ofknowledge about the reliability of a measurement, whereas error is the departure of a measurement from its true value. This error is hardly quantifiable very often and is defined as the difference between reality and a representation of reality. In the other hand, quantifying data uncertainty is an important part of spatial analysis, and researchers are still developing methods to assess, describe and reduce random and systematic DEM uncertainty. The common methods used for the assessment of the accuracy of digital elevation models - DEMs (like root mean square error or mean absolute error) are only global non-spatial measures. Their unquestionable advantages are their easy calculation and interpretation. However, as to environmental ap
