Abstract
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.
