In 1918 independent Lithuania territory was covered by maps of former Russian Empire (verst scale maps) and topographical maps of Kaiser Germany, which administrated Lithuania after War World I. Most of German WWI maps were made using maps of Russian Empire. For Lithuanians it was hard to interpret old maps, because these maps were in foregn languages, names of objects were perverted, information on maps were aged. Old maps were used till 1924, when military topographic office (Military Topography section) at General staff was established. In 1929 Topography section grow to the Topography department. It was concluded that basic map will be map in scale 1:25000. Till Second World War it was released 19 original maps and 73 recognized maps. (about 1/6 the territory of Lithuania). It was planned to prepare 823 (with the edge of the occupied Vilnius) or 542 (at the time the current territory of Lithuania) maps in scale M1:25000.
Maps in smaller scale 1:100000 were drawn using maps in scale M1:25000 by generalizing sheets, and where the photo (survey) was not yet done, using German S1:100 000 maps, correcting them according aerophotographical picture or recognition results. Till Second World War it was prepared 44 (+4) maps in scale 1:100000 to cover about 2/3 of the territory of Lithuania.
A third yet smaller scale maps were in 1933 published (in two sheets) in scale 1: 400 000 maps covering all of the ethnographic territory of Lithuania. This map was published in 5 variants.
