The creation of digital thematic soil maps at the regional level (with the map of soil carbon pools in the Usa River basin as an example)

Abstract

A digital map of soil carbon pools was created for the forest–tundra ecotone in the Usa River basin with the use of ERDAS Imagine 2014 and ArcGIS 10.2 software. Supervised classification and thematic interpretation of satellite images and digital terrain models with the use of a georeferenced database on soil profiles were applied. Expert assessment of the natural diversity and representativeness of random samples for different soil groups was performed, and the minimal necessary size of the statistical sample was determined.
