Abstract
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.
Highlights
Digital terrain model (DTM) can be created using photogrammetry, ground-based laser scanning, and ground-based geodetic measurements due to modern technological developments
DTM is a numerical representation in which the topographic surface of all or part of the terrain is attempted to be represented as a mathematical surface with a certain number of points
The model consists of grid cells, each of which has a height value and is equidistant from each other [1]. This surface is attempted to be mathematically represented on a topographic surface based on control points, the three-dimensional coordinates of which are determined
Summary
Digital terrain model (DTM) can be created using photogrammetry (aerial photographs and satellite images), ground-based laser scanning, and ground-based geodetic measurements due to modern technological developments. The model consists of grid cells, each of which has a height value and is equidistant from each other [1] This surface is attempted to be mathematically represented on a topographic surface based on control points, the three-dimensional coordinates of which are determined. Irregular grid (TIN model): a triangulation grid is generated from a group of points with known elevations, taking into account relief inflection lines and exclusion areas (for example, water surfaces, edges of construction sites). In the programs used by surveyors, the most commonly used interpolation method is interpolation based on Delaunay triangulation This method consists in constructing triangles that do not overlap each other, at the vertices of which the control points are located; the length of the triangle edge is set; it is possible to adjust the degree of surface smoothness. The familiar interface is the interface of the AutoCad program, so in the future it will be relied upon
