OGC API & STAC
Test a Proof of Concept app from MeteoSwiss
In a joint project of swisstopo and MeteoSwiss, an open interface for accessing ten MeteoSwiss products was provided. Selected data can be freely obtained via STAC-API and OGC API FEATURES for test purposes during the test period. The goal of the prototype is, among other things, to obtain feedback from users via online survey.
[EN] Ready to HACK weather and climate data and #OGC #OAFeat services from @meteoswiss and @swisstopo ? Join the @DINAconCH virtual hacknight on the 23.11 https://t.co/B26pV111yo pls RT #swissgis @OpendataCH @digiges_ch
— geo.admin.ch (@swiss_geoportal) November 8, 2022
The PoC will run until the end of November 2022. We are happy to support open initiatives like this as part of the DINAcon HACKnights and upcoming events like the GovTech Hackathon.

Start with the online tutorial (GitHub) and run some example queries in your web browser. Familiarize yourself with the context of this dataset, and log into GitHub so you can ask questions & share feedback.
Learn to use APIs implementing the STAC API Specification with the STAC browser, where you can already connect to geodata repositories around the world. Use the QGIS plugin if you would like to explore the data in an open source desktop GIS tool. See also the QGIS-OAFeat interface in the tutorial.
Use a command line API testing tool like curl, or an advanced GUI like postman to work with servcie endpoints more precisely. At this point you should be ready to try connecting to the API with libraries in your choice of programming language. Your thoughts about the security, performance and reliability of this solution are particularly welcome. Please raise an issue or share your tips in our community chat.
OAPI - POC
Proof of concept (POC) to ingest geospatial datasets from MeteoSwiss into a SpatioTemporal Asset Catalog (STAC) and expose as OGC API Features.
Terms of Service
- This service is experimental and thus not for operational use.
- This service is limited in time, from 1.8.2022 to 19.12.2022 .
- The service has limited availability and limited operating hours: It is frequently rebooted.
- During the limited service period, data can be accessed for testing purposes only. You must provide the source (author, title and link to the dataset).
- Further, when using this service, the disclaimer of the Federal Administration and the respective terms of use must be complied with in every case. You should therefore read the disclaimer carefully: disclaimer.admin.ch.
Documentation
OGC API and STAC are designed to be explorable through links
and a good starting point is the Landing Page (aka Root Catalog)
which links to capabilities, descriptions and fundamental resources of the services.
The OpenAPI
definition can be consumed through the SwaggerUI
. Select the appropriate server and authorization (for endpoints except GET) to try it out.
Be aware that the api definition is not in sync with the service implementation. There are addinonally transactional endpints for Collection
and Feature/Item
resources and the schemas/definitions might diverge from the actual implementation.
Usage
For now the basic use case is uploading a STAC Asset
through the load-asset
process. The input schema describes the json body
of the post
request passed to it's ./execute
endpoint. It requires the file as base64 encoded string, some asset properties, the collection id and the item id or an item object to create.
Example python scripts for loading an asset to an existing collection as well as extracting & creating a collection resource from a geocat.ch
entry are in the scripts folder.
Catalog Trees
Catalog trees can be created by adding collection resources with the property type
set to Catalog
and links with the relations parent
, child
and/or item
. Naturally these relations should be reflected on the linked ressources as well.
Consumption
The created resources can for example be consoumed with the STAC Browser. The assets contents accessible through the href
reside on a S3 bucket.
Tutorial
A TUTORIAL is provided to integrate
- Complete dataset browsing and donwload
- Feature data download via API with examples
- Integration in web and fat client applications
