For many years 3D models representing the terrain surface are used in various fields of science and engineering. The paper shows and describes the pro-cess of data implementation to the DTM, and reviews methods of creating DTM based on the TIN and GRID meshes. The paper presents methods for creating TIN meshes. It also describes the method of height interpolation in raster models based on the measurement data using various algorithms.

The article describes the results of research into the possibility of the use of spatial data available in the centers of geodetic and cartographic documentation for the modeling and visualization of rural areas, as well as the procedure to be followed from the analysis of spatial data available through their acquisition, ve-rification and processing procedure for modeling and visualization. ...
Modern measurement technologies such as laser scanning provides infor-mation about the reality that surrounds us in the form of point clouds. However, the information about the geometry of the objects stored in this form is often impractical from the point of view of the recipient. Therefore, it is necessary converting point clouds to vector models supported by CAD software. This paper presents the applicability and use some 3D modeling tools available in the software Leica Cyclone, as well as the accuracy of the fitting obtained geometry in the point clouds. ...
Monitoring and diagnostics of hydrotechnical objects provide knowledge about technical condition of the object. The main purpose of the evaluation process is to determine the technical condition at a certain time of use, by defining its stability and security. Technical diagnosis , defined as a set of methods and means to assess the causes, evolution and consequences of given set of technical facility, is a technical system. In the case of dams, monitoring and diagnostics based on active systems, deliberately designed , generating and processing information that are the basis for the assessment of their technical condition . In this article we present the opportunity to enrich the technical monitoring system of water dams by the technology of terrestrial laser scanning (TLS) . Terrestrial laser scanning is a device metrology , which in a non-contact measures the object and saves it in the form of an oriented point cloud . The analysis of the technical system, supported by TLS technology was conducted with regard to water dam in Rożnów. ...
