digital terrain model

Retrospective-geographical analysis of lviv city landfill

Aim. An annual increase in the amount of wasteburied at the solid waste landfill has forced the necessity to control activity of such communal and private enterprises and carry out both ecological and engineering performance monitoring. The parameters controlled by engineering monitoring include geometric size of land parcels, size and dynamics of the waste body, control for spreading of sewage disposal, and other numerical parameters which can be obtained by geodesic methods and by means of remote measuring.

The technology of digital terrain model creation on the example of defensive structures "Citadel" (Lviv)

Aim of this work is to create a digital terrain model of defensive structures “Citadel” using archival and modern cartographic data and aerial images. Objectives of the work is to develop technological scheme and describe the method of creation of digital terrain model and configuration of its 3D-visualization. Methods. Contour lines with 2m interval was created using fragment of modern topographic plan of Lviv, namely the area “Citadel” with scale 1: 5000, Altitude matrix was created on its base.
