Mapping based on open data sources in digital form

Abstract

Mapping based on open data sources in digital form represents a revolution in geoinformatics science and practice. Traditionally, the mapping approach required significant material resources and expertise to create accurate and up-to-date maps. With the development of geographic information systems (GIS) and an increasing number of websites that provide free access to a huge volume of geospatial information, this way of mapping is becoming more and more present. Open data sources, often free or at low cost, support the download or use of global geospatial data. This enabled the spread of geographical knowledge and skills at a much higher level, including individuals, organizations and social communities. Open data sources provide new mapping opportunities, enabling better understanding and solving complex problems in different fields. The paper systematizes knowledge and techniques from this area and, on the example of the Military Geographical Institute, shows the need for both the use and sharing of such data.
