The military became a decisive factor in the mapping of the 1800s through the establishment of the Danish General Staff, the introduction of a more detailed measurement system and the ultimate publication of large-scale maps. In addition, the very detailed economic survey was completed with a cadastral map at 1:4,000.

Society’s needs for maps could not be satisfied by these atlases and a number of private cartographers took over the publication of maps for a wider audience, such as the publication of county maps, school maps and, later, city maps for Trap’s topographic descriptions.

The private map publishers utilised the collected material supplemented with their own surveys, which resulted in a series of excellent regional maps of the entire country.

At the end of the century, the country was finally measured in satisfactory quality and with the development of the printing press the maps were now available to everyone.

This paved the way for measuring the Faroe Islands, Iceland and Greenland and for the development of other map products.
