Geospatial data

from Wikipedia, the free encyclopedia

Geospatial data are space-related data ( geodata ) from a specific subject, such as demography , epidemiology , soil science , climatology , election statistics . Frequent areas of application for geospatial data are surveys by administrations, e.g. B. in the areas of environment, statistics or planning. In general, all geospatial data that do not fall under the basic geospatial data can be designated as geospatial data . In contrast to factual data , geospatial data are basically independently meaningful geodata and have a clear (direct or indirect) spatial reference .

This spatial reference can either be directly through coordinates or indirectly, for example through reference to geographic reference data, address details, postcode areas , administrative or statistical territorial units such as municipal areas , rural districts , employment office districts , etc. getting produced. The spatial reference can also be related to linear objects, such as traffic data .

With regard to the topicality, flexibility and performance of the data, high demands are therefore placed on the spatial data infrastructure. It is necessary to ensure that the partially heterogeneous geospatial data can be converted into uniform data formats via standardized interfaces for further use .

Geospatial data can be referred to as official geospatial data if their authenticity and the consistency of their data management are guaranteed and they are the responsibility of a body entrusted with the performance of sovereign tasks. Official geospatial data based on binding terminology are of growing importance for the interoperability of heterogeneous data systems.
