Smart Mapping: The new vector map is online

08th August 2022 The new vector-based web map has been launched on August 1st, 2022 with the product name basemap.de Web Vector. Together with the other basemap.de services, these products are official, up-to-date online maps of Germany that can be used free of charge. The strengths of the vector-based web map lie in the flexibility in designing the content and the high-resolution presentation.
At the same time, the new shading service was activated. With basemap.de Web Raster Shading, a Germany-wide shading service for subsequent use in any technical and thematic maps is provided. The service contains oblique shading, a combined shading of oblique and embankment shading as well as a height layer display based on the ATKIS-DGM5 of the surveying authorities of the federal states.
All details about the services can be found on the product web page.
You can use the basemap.de viewer to view the maps, but you can also use them on the go via smart phone, print them out, adapt them and release them for specific sections.

13th May 2017 In the AAA® project, AdV conceived an integrated and coordinated modelling of all geospatial data from the Surveying, Mapping and Cadastre Authorities of Germany and implemented it through its member administrations.

In addition to the current version 6.0.1 of the main document, version 7.0.2 is also available in English.

Guidelines for the nationwide uniform archiving of geographic reference data

1st January 2017 For many years surveying and mapping authorities and the archive authorities of the Laender of Germany are working together with regard to the delivery of analogue products, particularly maps. More and more the surveying and mapping authorities produce digital data, and new ways have to be set up for basic uniform regulations for the process of archiving digital geographic reference data.
For this reason, AdV and the Conference of Directors of the Archive Authorities of the Federal Government and the Laender (KLA) appointed a joint working group to develop a document on a harmonised approach to this challenge. Both AdV and KLA adopted the resulting guidelines at the end of 2015. The complete document has now been translated into English
