Foreword: This section currently contains about 7,500 registered maps, nautical charts and site plans. In line with the DTM's interest, the focus is on traffic maps. One of the oldest maps in the collection is a collection of very decorative nautical charts, mostly from Europe. They date from the 17th and 18th centuries. The collection of the Museum für Meereskunde includes a number of nautical charts from the period 1860 to about 1920. Finally, there are a number of more modern nautical charts, mainly from the German coasts, which were handed over to us by the Förderverein. So there are many examples for the development of the nautical chart. The early postcards and travel cards were used for traffic on land. This genus is represented by some cards from around 1800. With the increase of private journeys with the development of the railway, the demand for maps for the German and European area also grew. This can be clearly seen from the various railway and travel maps of Central Europe which were published by numerous publishers from the 1940s onwards. The rapid growth of the railway network can be easily tracked on the maps. These maps also clearly show stagecoach connections next to the railway lines until after 1900. The geographical focus of the map collection is on Berlin - Brandenburg - Germany - Central Europe. Thus the German area is well covered with the railway maps. From the "Metzeltin" (railway historian) collection, however, many maps on the subject of railways from overseas have also been added to the DTM collection. In the last half of the last century, another popular type of traffic map appeared: the road map. In the beginning still under the name "Cyclist Card". Later they are called "cyclist and motorist maps" and finally only "car maps". Until the 1930s, many leading petrol distributors, tyre manufacturers and some well-known publishers in Germany had card series for the German-speaking countries in their product range. Examples of map series publishers are Aral/BV, Olex/BP, Standard/Esso, Stellin/Shell, Continental, Ravenstein and Ullstein/BZ. This area is well represented in the DTM portfolio. Examples of almost all series are available, some series are almost complete in single sheets, but rarely available in all editions. With the increase in leisure time and mobility from the beginning of this century, more and more hiking maps appeared. They are increasingly available in the DTM map collection for holiday areas such as Schneekoppe and Harz, but also for trips to the Mark Brandenburg. Particularly numerous Silva and Pharus hiking maps have been preserved. The very exact maps of the Reichsamt für Landesaufnahme in Berlin were very popular for the closer surroundings of Berlin. The series "Karte von Berlin und Umgebung in 12 Blätter" on a scale of 1:50,000 was published from 1901 to about 1943 in several new editions. In the 1930s, a series of maps for water hikers was published covering the Brandenburg and Mecklenburg lakes and waters. Today, this type of map becomes up-to-date again and the older maps are used for information purposes. The urban developments in the Berlin area can also be clearly seen in the city maps. For the period after 1870, plans of Berlin are available at short intervals. The development of local public transport can also always be seen on city maps. However, it can be more directly traced on the maps of the Public Transport Classification Group. A large number of maps from Berlin are also available here. Among the early maps are the Droschken path knives from the period 1880 to 1920. Some maps of the Berliner Straßenbahn Betriebs GmbH and the Hochbahngesellschaft are also available. However, the focus is on the BVG line networks, which have been represented in large numbers in the portfolio since 1930. A collection of about 10,000 nautical charts from the former Institute of Geography, which was taken over by the TU Berlin, is stored and accessible according to the publisher's system. The training in this database takes place as required.
