The »Spezialkarte der Oesterreichischen-ungarnischen Monarchie« is a topographic map at the scale of 1: 75,000. Topographical maps are the basis of national cartographic information systems, necessary for making other thematic maps and cartographic representations, a tool for defense planning, orientation, etc.

The Spezialkarte der Oesterreichischen-ungarnischen Monarchie at the scale of 1: 75,000 is one of the most exact maps of its time. Due to the development of geodetic techniques and outdated maps available, a new measurement of the Habsburg Monarchy began towards the end of the 19th century - today called "the third military survey". It was carried out between 1869 and 1887. In 1880, the first sheets were made. Ordnance survey maps were used for orientation purposes. They cover the area of 7'30'' latitude and 15' longitude. As they were of high quality, several updated reprints of the maps were published until 1940. The Slovenian territory was covered on 27 sheets.

Topography is the study of the forms and features of land surfaces. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms. Topography as a field of geoscience and planetary science is concerned with local detail in general, including not only relief, but also natural and artificial features, and even local history and culture.

State topographic maps at the scale of 1:50.000 are important elements of national cartographic information systems. They are the basis for other maps and thematic cartographic presentations, an instrument for defense planning and for orientation purposes, etc.

Topographic map of Yugoslavia at the scale of 1: 50,000 for the territory of Slovenia comprises 56 sheets printed from 1950 to 1967.

The Gauss Kruger transverse conformal cylinder projection and the Greenwich starting meridian were used.
