Inhalt:
The recent years have seen increasing progress towards the provision of open geodata in Austria. This includes high-resolution topographic models, such as digital terrain models (DTMs), surface models (DSMs), and orthophotos (OPs) from the BEV. With their availability, any interested user can download and use the data for his/her respective task. While this data thus becomes accessible to a potentially large user group, this leads, however, to avoidable redundant work as the same processing steps (e.g., resampling, reprojection, derivation of further topographic parameters) are potentially repeated locally by various users. Inspired by the processing and provision of satellite-based EO data, we believe that the distribution of high-resolution geospatial data needs to go one step further in order to realize the maximum potential of the data, reduce redundant work, and eliminate remaining access barriers. Therefore, we integrated available DTM, DSM, and OPs datasets into the central data catalog of the EODC, which allows uniform access to all datasets through various interfaces (e.g., Python, QGIS). This includes not only the most recent releases (i.e., Stichtage), but also all previous ones, establishing a time series of high-resolution products of Austria, including their metadata (e.g., acquisition date). Additionally, we derived further topographic parameters, which we believe are useful for a wide range of users. Within this talk, we will shortly outline the technical aspects and subsequently demonstrate the established infrastructure in selected use cases. To give interested listeners the opportunity to gain first-hand experience, we will organize a practical hands-on tutorial one week after this initial presentation.
Vortragender:
Sebastian Mikolka-Flöry studied geodesy at TU Wien, where he is currently a project assistant at the research unit Photogrammetry. Previously he worked in several geodesy related fields ranging from archaeology (LBI ArchPro) to meteorology (Ubimet GmbH). While his research at TU Wien has so far focused on the processing of unstructured historical oblique image collections, he is now actively involved in two additional projects (TOPO4EO and imvEOm, both funded by the FFG) that deal with the integration of high-resolution topographic data with satellite based earth observation to improve the countrywide monitoring and prediction of vegetation dynamics.
