DESCRIPTION:Government agencies collect and share digital terrain models an
 d aerial imagery as open data. Terrain and aerial imagery are often used a
 s background below OpenStreetMap vector data on interactive web maps. But 
 so far\, only commercial actors have aggregated open terrain and aerial im
 agery datasets at scale into a unified data product. The Mapterhorn projec
 t aims to bring together all available open terrain and aerial imagery dat
 a in one place and share it free of charge as PMTiles downloads. In this t
 alk\, we will first have a look at the terrain pipeline which was applied 
 to more than 15 TiB of raster elevation data. We will then look into how t
 he aggregated terrain PMTiles can be used in applications. Finally\, we wi
 ll discuss the ongoing efforts to extend the existing terrain pipeline to 
 aerial imagery.
