Digitized data about the surrounding space is used to create automated cartographic and geographic information systems.
Compared to traditional paper maps, electronic models have the following advantages:
- the ability to dynamically change the topography and location of various objects;
- quick terrain scaling;
- higher accuracy and absence of distortions;
- possibility of digital marking and instantaneous search for the necessary object;
- automatic routing and control over deviations from the selected course;
- possibility of transferring digital maps via Internet.
Electronic maps are not subject to wear and tear, they can be stored in computer memory and on stationary carriers. Digital cartography and three-dimensional modeling serve as an important source of information in the design, repair and reconstruction of buildings, as well as various infrastructure facilities. The data contained in electronic maps are used to solve the following tasks:
- evaluation of soil conditions and geological exploration;
- modeling natural and man-made emergencies;
- drawing up cadastre plans and taking inventories of land resources;
- creation of atlases, albums and encyclopedias;
- construction of visibility zones and determination of places of confident radiolocation;
- geomarketing;
- optimization of logistics of enterprises and transport companies.
Digital maps are actively exploited by tourists, sportsmen and travelers. Electronic cartographic information is used when searching for missing people and planning rescue operations.
