The main materials and data necessary for the surveyor to conduct topographic and geodetic work include the state geodetic network points and topographic tablets on the survey site. All these data, as well as the aerospace data and other cartographic material, are under the jurisdiction of the Federal Fund (Federal Scientific and Technical Center for Geodesy, Cartography and Spatial Data Infrastructure). This organization is subordinate to the Office of the Russian Federal Register. However, today, when working with the site, there are a number of problems: there are no updates to the cartographic material, coordinates and altitudes for the polygon points of the Fund, the Fund website does not have a common database in open access concerning actual information about the State Geodesy Networks (SGN) points’ state.

Modern document management of topographic production was formed and developed since Soviet times, but with the development of market relations, the number of its participants (customers, manufacturers and consumers) has increased significantly. Thus, the role of the geodesist in the construction industry is expanding significantly. The task of the surveyor is to communicate with all participants of the engineering project: architects, representatives of design organizations, planners, engineers at the construction site, utilities, tenants, representatives of government and others. The purpose of this study was to analyze the production interaction between the customer of the work and the geodesic organizations (the survey executor). The survey by questionnaire, which we conducted, was attended by representatives of design organizations that are engaged in the preparation of project documentation for the construction (reconstruction or overhaul) of buildings and structures of various levels of responsibility, and survey organizations that are engaged in the preparation of technical reports on engineering and geodetic organizations.

The article discusses the construction of a digital terrain model in various programs, which will be used for the vertical planning design. One of the major challenges in this area is the creation of an accurate and realistic surface, which will give an opportunity to create a quality and compliant site. To solve this problem and analyze, a model of the same territory and the same initial data has been built. The paper presents a construction algorithms DTM a method of constructing an irregular grid of heights, graphical implementation and analysis.

The article describes the state of the geocentric coordinate system of the Russian Federation. Current problems of the geodetic coordinate system are described, and a method for solving this problem is proposed.
