You can change the colors, the hillshade settings, turn on borders and labels, and much more!

And you can turn on seafloor data, so you can finally see all the hills and mountains hidden under water relief.bertspaan.nl/world?lang=e...

For the Netherlands, it uses data from the AHN, for an even higher resolution: relief.bertspaan.nl/ahn?lang=en#...

I've made an interactive map for exploring the terrain of the world! It uses @mapterhorn.com data and tiles, and WebGL for dynamic colors and animations. relief.bertspaan.nl/world?lang=en

The new map uses a combination of raster tiles and vector tiles to make sure all buildings will always be visible. You can't do this with just vector tiles: a single vector tile would be 10s of megabytes on low zooms. Raster tiles when zoomed out and vector tiles when zoomed in solves this!

You can still explore the first version of the map here: code.waag.org/buildings/. Then, there were 9,866,539 buildings in the Netherlands. Right now, there are 1,467,339 more: 11,333,878 in total. The new version of the map lets you see where new buildings have been built in the past 10 years.

We had so many exciting plans for the remainder of the grant—this is truly disappointing news. I'll really miss collaborating with the Leventhal Center and the American Geographical Society Library, but the Allmaps project will continue!

If maps from your city are missing, you can make them available in Allmaps Here by georeferencing new maps with Allmaps Editor: editor.allmaps.org
