Abstract
The paper describes the methodology and presents the results of the calculation of the spectral characteristics of the terrain for the territory of the Bolshezemelskaya and Malozemelskaya Tundra (the north of the European part of Russia). There are nine terrain clusters, differing in the topographic dissection pattern. Their geomorphological interpretation is given. Three clusters characterize mountainous and coarsely hilly terrain with the depth of dissection from 150 m and more. The others are low and elevated terrains with much lower depths of dissection (up to 50 m) and different patterns of interposition of landforms.
Highlights
Landform and hydrographic pattern analysis and classification might be produced using the focal terrain characteristics such as topographic position indices [1] or others
Focal variables depend on density and magnitude of dissection for different types of the landforms
We develop the technique of spectral terrain variables or characteristics (STC) computing [2]
Summary
Landform and hydrographic pattern analysis and classification might be produced using the focal terrain characteristics such as topographic position indices [1] or others. Focal variables depend on density and magnitude of dissection for different types of the landforms. We develop the technique of spectral terrain variables or characteristics (STC) computing [2]. These variables are aimed to describe the topographic pattern type by one numeric value. Each spectral characteristic of the terrain characterizes different features of topographic drawing, and together they allow distinguishing the areas with a homogeneous character of the terrain (and possibly its origin)
