| Summary: | Prompt receipt of reliable information about the terrain with sufficient detail is
one of the main tasks in the fields of national economy, territorial development or
research of large territorial units. The multiplicity of error sources in Earth remote
sensing materials is due to a number of factors, and the resulting terrain models
have a certain degree of generalization, which directly affects the correctness of
digital terrain models. This article is devoted to the analysis of existing methods for
estimating errors of open digital terrain models in order to increase their accuracy.
Correct digital elevation models have a high similarity to reality and can be used in
regional studies to determine the morphometric indicators of the territory. |
