The article shows characteristic of regional features of oilfield’s geoecological risk (with Saratov region as an example). Geoinformation systems (GIS) and mathematical and cartographical models as a tool of their analysis are disclosed possibilities of using

In the real article advantages of application of hybrid-type DEVICE are shown in the operative gone into detail long-term prognostication of elements of weather and the key moments of the use are described hybrid-type DEVICE in the working chart of drafting of such prognosis

The article shows the main problem questions of Land use and development rules of settlements’ territories creation. Problematic aspects of Rules development related of making changes in existing Rules in accordance with the classifier of permitted land use, difficulties in identifying and mapping boundaries of zones with special conditions of use, resolve contentious issues at public hearings are defined.

This article is devoted to questions of digital modeling of river basin area. The basin of the Tereshka River appears as the research object. The author results detailed algorithm of river basin geomodeling by using of computer software (ArcGIS, ESRI) on the basis of the space data (SRTM). Characterizing relief and water flow models are created. As a result watersheds and stream network are delineated.

The article represents results of scientific-innovation educational centre of geoinformational technologies (GIS-centre) activity. Also briefly reports projects realized by GIS-centre concerning of GIS methodology implementation to Povolzhie’ scientific-production and production organizations and lay down general working trends of the Saratov State University new innovation organization – the interregional centre of space monitoring. 

The article provides the experience of joint work of urban ecologists and oncologists in identifying and preventing the thyroid cancer in Saratov. Oncogeographic works were based on the geo-ecological research data, which made possible to determine the most polluted urban landscapes. The medical- geographic analysis was made with the help of using GIS technology. Urban ecological work precedes screening studies. Also, it is the basis of oncological monitoring.

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.

Malignant neoplasms of the lymphatic system, which are characterized by damage to groups of lymph nodes and/or damage to internal organs are called lymphomas. The analysis of statistical data shows that there is incomplete information about the incidence in specific regions. The study of the prevalence of lymphomas, the need to monitor the incidence, and the identification and analysis of possible links between pathology and urban environmental features are an urgent problem.

In the article, in a comparative analysis, for the periods from 1991 to 1998, 2015 and 2022, the issues of the territorial prevalence of basal cell skin cancer in Saratov are considered. The residential areas of patients were studied and mapped taking into account risk factors. The result of the study was an oncoecological analysis of urban landscape sites and the creation of a scheme for the active search for early forms of skin cancer.
