Structure of Export of Regions of the Lower Volga Region and Prospects of Their Industry

The issues of connection of manufacturing industry of the region and the structure of its exports are considered. Features of export of some regions of the Middle and Lower Volga region during the last two years are analyzed. An assessment of the effectiveness of export activities is given. On the example of the Saratov region shows a change in the structure of exports for the period 2013-2017. The question of possibilities of import substitution in the Saratov region is raised.

Studying Linear Erosion by Means of Creating a Refined Digital Elevation Model Based on SRTM (The Khvalynsk District of the Saratov Region as an Example)

This article considers the methodology for constructing a digital elevation model and its derivatives for analyzing the spatial distribution of linear erosion processes using the territory of the Khvalynsky district as an example. The authors propose the creation of a refined terrain model based on SRTM radar data, topographic maps and the interpretation of Earth remote sensing data. The creation technology is described and a comparative analysis of the refined model with the base SRTM is carried out.

The Development of an Algorithm for Constructing the Flood Zones Using Geoinformation Technologies (on the Example of the Medveditsa River Section Near Petrovsk)

The article discusses aspects of developing an algorithm for flood zones modeling using modern geographic information technologies in the area of the river near the town Petrovsk. The integrated approach to the flood zones modeling of different hydrological magnitude is considered. As a result of the developed algorithm application, flood risk areas with different probabilities (1, 5, 25 and 50%) with an indication of the depth of flooding are identified.

Spatial planning at the macro and micro levels: Problems of taxonomy and polarization (on the example of the Volga-Ural macroregion)

The issue of spatial planning includes the subject of taxonomy. It seems that it is necessary to switch to the practice of planning, in addition to the meso-level (subject of the Russian Federation), at two taxonomic levels: the macroregion and the economic microdistrict. To do this, the article identifies the main properties of these formations. On the example of the Volga-Ural macroregion the properties of integrity, complementarity and connectivity are analyzed.
