Over 100 Finnish raster datasets are now available via Paituli STAC – Spatio Temporal Asset Catalog! STAC is a specification to describe geospatial datasets with temporal dimension. 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. The benefit for user comes from the fact that STAC drastically simplifies searching and downloading datasets. Very good news for those whose research involves heavy spatial time-series data!
