Abstract

Abstract. For the last two decades surface information in the form of conventional digital and analogue topographic maps has been being supplemented by new digital geospatial products, also known as 3D models of real objects. It is shown that currently there are no defined standards for 3D scenes construction technologies that could be used by Russian surveying and cartographic enterprises. The issues regarding source data requirements, their capture and transferring to create 3D scenes have not been defined yet. The accuracy issues for 3D video scenes used for measuring purposes can hardly ever be found in publications. Practicability of development, research and implementation of technology for construction of 3D video scenes is substantiated by 3D video scene capability to expand the field of data analysis application for environmental monitoring, urban planning, and managerial decision problems. The technology for construction of 3D video scenes with regard to the specified metric requirements is offered. Technique and methodological background are recommended for this technology used to construct 3D video scenes based on DTM, which were created by satellite and aerial survey data. The results of accuracy estimation of 3D video scenes are presented.

Highlights

Over recent years analogue and digital topographic maps are becoming insufficient for many branches of Russian economy that needs more data on territories
It is proved by a large number of Russian 3D digital city models that are available on different web-sites and in publications. 3D models provide terrain visualization and help on to choose the best solutions for various issues taking into consideration the details of a particular plot
Tools by initial digital elevation model (DEM) and DOM obtained by various means for capture and processing of cartographic data, satellite and aerial imagery, laser scanning data, SAR interferometry, geodetic data, etc. In this case digital models should be converted into 3D GIS environment; - 3D video scenes are constructed in the unified software package beginning from the initial data processing to the end-user product
