Geographical Information Systems (GIS) and Building Stock Survey

The lecture gives an overview about instruments, equipment and technologies for geographic information systems (GIS) and building stock survey. It covers advanced topics like reference coordinate systems, global map quality and availability of input data (geodetic, photogrammetric and remote sensing data).

The course is managed via the learning platform Moodle. All documents and further information can be found in the Moodle course Geographical information systems (GIS) and building stock survey WiSe2020.

Please notice: The materials for our lectures and exercises are only available through the network of the Bauhaus-Universität Weimar.
