Remote sensing is used to obtain information about the earth's surface with the help of electromagnetic waves (e.g. light) or by means of sound waves. In contrast to other methods, remote sensing enables the non-contact investigation of large areas of the Earth's surface. It is used for mapping in surveying and cartography, for data acquisition in geoinformation or for monitoring natural and anthropogenic changes in areas of interest. Remote sensing offers the possibility of recording large areas in high temporal and spatial resolution and is of great importance for a wide range of specialist areas such as (e.g. regional planning and land use planning, agriculture and forestry, civil engineering, architecture, archaeology, industry, etc.).

• The thematic evaluation of historical and current aerial photographs with regard to different issues (explosive ordnance, contaminated sites, land use, environment, etc.).
• the orthorectification and georeferencing of historical and contemporary imagery
• the creation of orthophotos and orthophoto mosaics
• Deriving digital terrain and surface models (DTM, DOM) from current aerial photographs and drone flights
• the reconstruction of historical terrain surfaces
• The collection and processing of aerial photographs and subsequent products by means of UAV (Unmanned Aerial Vehicle)/drone flights for the purpose of monitoring, volume calculation and determination of surface and volume changes, e.g. in the context of construction site documentation, soil management, waste management, open-cast mining, environment, etc.
