Digital Topographic Map (DTM) is a digital model of the terrain recorded on a machine-readable medium in an established structure and codes, in the projection, grid, coordinate system, and heights adopted for the map, with accuracy and content corresponding to a specific topographic map scale.

DTMs are created in scales of 1:10000, 1:25000, 1:50000, 1:100000, 1:200000, 1:500000, 1:1 000 000, and formed as arrays of digital cartographic information (multiple objects of DTM) covering areas of territory, limited by the frames of sheets of corresponding topographic maps of the same scale.

What is it used for:

Digital Topographic Maps of scales 1:10,000 and 1:25,000:

Purposes and objectives of creating Digital Topographic Maps (DTM)

The main purposes of creating digital topographic maps are:

  • Graphic representation of spatial relationships and distributions;
  • Improving the ability to analyze, process, and display geoinformation data;
  • Automation of mapping and cartographic analysis in management systems;
  • Obtaining expert decisions in graphic form in real-time and separate time modes.

The main objective of creating (updating) a digital topographic map is to produce cartographic products that closely correspond to the actual state of the terrain, created in accordance with current regulatory and technical documents and the Technical Task.

Digital topographic maps are used in:

  • In agriculture - for land use planning and land accounting in areas of intensive agriculture, as a basis for detailed soil surveys and erosion control measures, etc.
  • In land reclamation - for preparing projects of land reclamation and conducting surveys for irrigation and drainage of lands;
  • In geological exploration - for detailed prospecting and exploration works, for ties during geological and geophysical surveys;
  • In the development of oil and gas fields - for preparing plans of the developed area, projects for the arrangement and location of wells, tying various engineering objects, etc.;
  • In hydraulic engineering - for selecting the site of a hydro unit and developing projects for reservoirs in flat areas, for surveys of canals and designing protective structures.
The basis for creating/updating maps also includes requirements for surveying works in the development of mineral deposits, construction of mining enterprises, and use of subsoil for other purposes. The creation and updating of digital cartographic bases of various scales are required to bring their content in line with the current state of the terrain. Topographic maps at a scale of 1:25,000 are actively used starting from the stage of designing the field. These maps allow designing roads and major structures. Existing objects, elements of hydrography, and vegetation that may hinder work can be accurately determined. Maps at a scale of 1:25,000 are also used to tie various engineering objects, to form the route of a pipeline, and to determine the placement of a well network in the area of interest. The maps at a scale of 1:25,000 show objects such as industrial enterprises, mines, quarries, drilling rigs, oil and gas wells and fields, oil and gas pipelines, fuel depots, etc. However, maps at a scale of 1:25,000 are not sufficient for designing and constructing infrastructure facilities at deposits. For the design and construction of infrastructure facilities at deposits, topographic maps at a scale of 1:10,000 are used. The accuracy of these maps allows for precise tying of structures on the ground and distribution of all roads, both motor and pedestrian. During the development, arrangement, and operation of oil and gas fields, continuous construction, reconstruction, and dismantling of production facilities and engineering communications are carried out. Therefore, there is a need to update topographic maps (plans) reflecting existing and planned facilities. DTMs of scales 1:50,000, 1:100,000, and 1:200,000 are intended for studying and evaluating the terrain, for measurements and calculations during the design and construction of military engineering structures and facilities, and for preparation, management, and determination of coordinates for starting positions in military units. DTMs of scales 1:500,000 and 1:1,000,000 are intended for studying and evaluating the general nature of the terrain for operational planning and are also used in aviation as aeronautical charts.

Advantages of using Remote Sensing Data (RSD)

  • Archival data is already available to the operator;
  • Ordering new data does not require any approvals from competent authorities;
  • Satellite imagery does not require on-site visits, unlike aerial imagery and UAV-based imaging.

Digital Topographic Maps are electronic representations of geographical features, capturing elevation, landforms, and other natural or man-made details. Unlike traditional paper maps, digital versions can be viewed on electronic devices, allowing for dynamic updates, zooming, and interactive features.
Elevation in Digital Topographic Maps is often depicted using contour lines, which connect points of equal elevation. This information is crucial for applications such as geographic analysis, land planning, and infrastructure development, as it provides a comprehensive understanding of the terrain.
GIS technology is instrumental in creating and utilizing Digital Topographic Maps. It enables the integration of various spatial data layers, facilitates analysis, and allows for the dynamic creation of maps. GIS enhances the functionality of Digital Topographic Maps for applications like urban planning, environmental monitoring, and natural resource management.
Digital Topographic Maps are vital in disaster preparedness and response by providing accurate and up-to-date information about the affected areas. Emergency responders use these maps to plan evacuation routes, identify high-risk zones, and coordinate relief efforts, aiding in efficient and effective disaster management.
Users can interact with Digital Topographic Maps through various means, including zooming, panning, and toggling layers. Additionally, the integration of GPS technology allows users to determine their precise location on the map in real-time. These interactive features enhance user engagement and provide personalized, on-demand access to geographic information.
