Thanks for submitting this @alalt . Just some changes from me regarding the path of images. Otherwise, they won't show on the web page.

Can we make this one as Featured @timlinux ?

Since 2022, the website openko.de has offered over **21,000 alternative PDF tables and maps** for free download. In addition to the tabular data, each PDF includes a map showing the location of the corresponding grid cell.

Navigation to the appropriate KOSTRA grid cell is provided via a web map ([Interactive Map KOSTRA-DWD-2020](https://www.openko.de/kostra-dwd-2020-tabellen-kostenlos-herunterladen/)) with integrated address search (Click on "Interaktive Karte KOSTRA-DWD-2020" to reach the map).
