The search in the metadata catalogue is publicly accessible. In order to access the geodata in the respective services (download service and web services), however, authentication via SWITCHaai is required.
The authentication process depends on the service selected:
- For access to a web service dataset, the corresponding dataset is loaded into the desktop GIS as a geo-web service via the link in the detailed view of the hit. The authentication is performed directly in the desktop programme.
Data access download service
The data access via the download service is browser-based. The datasets available can be displayed directly on the browser and (depending on the dataset) limited to individual layers, a particular resolution or a particular timeframe. The extract selected can be downloaded for further processing in your own GIS programme.
The dataset selected (e.g. swissimage) is automatically added to the “active layers” and displayed.
Various timeframes can be selected for the data via “Time controls”.
You can zoom directly with the mouse or by entering the desired locality in the search field (e.g. Zurich).
Additional datasets can be displayed (e.g. swissTLM3D rail lines). These are either sought via the search field or selected directly via “Select datasets”.
For the download, an extract (“extent”) needs to be defined (by selecting it directly with the mouse or entering coordinates).
The selected datasets (“active layers”) are then added to the “download list” individually or altogether (“get all”). It is possible to save the download list or share it with other users.
The data excerpts can then be downloaded to your own computer from the download list in different output formats (default: ESRI shapefile) and opened and processed in any software programme (such as CAD or graphics editing software).
Data access web services
The geodata4edu.ch web services offer the available datasets as map, feature or image services for integration in your own GIS programme and thus allow the geodata to be worked with directly (exploring, displaying, extracting…).
Various functionalities can be used in the desktop GIS:
- Adding geodata from geodata4edu.ch or other data sources and formats
- Changing symbolisation and processing the geodata further
- Displaying object details
For extensive analyses, the data can be saved locally:
Other datasets can be saved in various formats via “Extract data” and processed further.
Entire datasets, including data models, can be saved and processed further via “Replica”.
