A collection of datasets from various Dutch institutions to demonstrate a Spatial Data Infrastructure built on Portolan.
Kaartblad 32 covers Amersfoort and surroundings — the origin of the Dutch national coordinate system (EPSG:28992, RD New). The Onze Lieve Vrouwetoren church tower marks X=155000, Y=463000. Also includes Zeist, Leusden, Woudenberg, and the Utrechtse Heuvelrug forest ridge. This is the only sheet with both RGB and RGBNIR (4-band) COGs. Part of the Luchtfoto 2024 collection — 25 cm orthophotos from the Beeldmateriaal Nederland summer campaign, served as Cloud-Optimized GeoTIFFs (COGs).
