Creating a database of russian toponyms of Baltic states
Abstract
The article considers the issues of creating and using specialized geographical information system database of toponyms which have been renamed in the Baltic states. In addition, the article covers the issues of developing the structure and content of the spatial database of the Baltic states settlements for a detailed study and mapping of changes in their names based on the study of topographic maps of the Baltic States at a scale of 1:1 000 000 (1989) and modern space images.
Global positioning systems for engineering and geodetic surveys
Abstract
The article is devoted to the use of global positioning systems in conducting engineering and geodetic surveys. Based on field geodetic measurements, the accuracy of GPS- definitions of vectors from the starting points of the OMS to the determined points of the reference network (benchmark) was estimated, an engineering-topographic plan of a scale of 1:500 was created.
Map analysis of Tatar settlements on the territory of the republic of Mordovia in 2010
Abstract
The article provides a rationale for the use of GIS packages for creating digital maps. One of the maps created for the time period from 1959 to 2010 is considered in more detail. The results of the map analysis of Tatar settlements in 2010 in the Republic of Mordovia are discussed and the corresponding conclusions are drawn.
Designing and creating a series of demographic maps of territorial entities of Volga Federal district
Abstract
The article discusses the technology of designing and creating a series of maps of the most important demographic indicators – fertility, mortality and natural population growth of the territorial entities of the Volga Federal District of Russia. A brief preliminary analysis of the results of the work done and the created maps is given.
Making annual air temperature maps of the territory of the republic of Mordovia using GIS technologies
Abstract
The article studies the spatial and temporal features of air temperature changes on the territory of the Republic of Mordovia using GIS technologies. As a result, a series of thematic maps has been created. Considering the new maps, it can be concluded that a positive increase in the average annual air temperature was recorded on the territory of the Republic of Mordovia, which indicates a warming trend. The created maps can be used for further climate research.
Usage of GIS technologies for adding river data to database
Abstract
The experience of adding characteristics of the rivers of the Republic of Mordovia to the GIS database based on the reference book "Hydrological Knowledge" is described. When working with linear objects, the functionality of ArcGIS is used. Special attention is paid to assessing the temporal reliability and updating of data.
Internet services for obtaining space information for the territory of the republic of Mordovia
Abstract
Over the decades of the existence of artificial Earth satellites and remote sensing systems, a huge number of images of the Earth's surface have been collected from space. For their interpretation, methods of decoding satellite images were developed, and decoding features of objects on the Earth's surface were identified. Despite this, there are great difficulties in obtaining high-quality space information for a specific territory. In the present paper, an attempt is made to briefly characterize some servers on the Internet for obtaining free space information for conducting a number of courses focused on the use of satellite images.
Use of unmanned water vehicles in mapping and modeling
Abstract
The article discusses the use of unmanned water vehicles, which are becoming more wide-spread at present time, in mapping and modeling. The authors consider some examples of the use of sensors on unmanned water vehicles, based on current technologies, which allow you to do projects that meet modern requirements.
