Creation of a digital map for Sochi city masterplan development in the modern geoinformation system ArcGIS

Abstract

Today, taking into account the development of modern geodetic and cartographic technologies, it is impossible to solve the tasks of territorial planning without using modern geographic information systems. The main tasks of GIS are the search for solutions in the field of rational use of natural resources, territorial sectoral planning, and management of the location of industry, transport, agriculture, energy, and finance. In addition, GIS systems provide control of living conditions of the population, as well as regulate the issues of mapping. The article discusses the application of modern GIS as methods of creating topographic plans. For work on creation of digital terrain models space images are used, which should be accompanied by data of territory interpretation. This allows to make sure the accuracy of information contained in cartographic open databases and to compare it with the current situation on the projected territory. To build a GIS it is necessary to use special integrated programs that allow to create, analyse, edit and present spatial data. The paper examines the process of creating a GIS using ArcGIS programme. The purpose of this paper is to study the process of creating a digital map and database with all the information of common attributes. The developed digital map is the basis for the formation of the master plan of the city. The master plan consists of an explanatory note and a set of drawings. The drawings should be made on a certain scale (1:200 - 1:2000). It is necessary to take into account natural conditions, wind rose, and other data. All objects on the drawings shall be designated with the help of conventional signs established by the relevant regulatory documents. The general plan of the city shall comply with the territorial planning documentation.
