This workshop is for new users of STAC – Spatio-Temporal Asset Catalog. STAC is a specification to describe geospatial datasets with temporal dimension. It drastically simplifies searching and downloading datasets. STAC includes only the metadata of datasets and links to the actual files. The data files themselves are usually stored in the cloud. STAC is most often used for remote sensing imagery and other raster data, but it can be used also for vector and point cloud data. STAC is especially suitable for time-series applications.

CSC has recently open Paituli STAC, which includes several Finnish datasets and more will be added soon.

Topics of the workshop:

• General introduciton to STAC
• Data contents of Paituli STAC
• Hands-on exercise, how to use STAC from Python and R.
• Discussion

For hands-on exercise we will use CSC Notebooks service with JupyterLab and RStudio, so participants do need to install anything to their own laptops.

See Paituli STAC page for more information, inc links to Python and R examples.

Workshop materials:

• Slides
• Python example
• R example

The workshop is free of charge, but registration is required by 11.6.2023.
