For a while I've been working on an offline topo maps site for NZ and its finally in a state worth sharing.

  • mountains and routes from ClimbNZ
  • hut locations
  • slope angle for assessing avalanche danger
  • 3d view

That is insanely good!

It's rare to have something so usable, on mobile, in browser.

Top class work.

I've been toying with a personal mapping app. Nothing like you're doing, but the chunking and level of detail data streaming etc is melting my brain.

Again. Fantastic work. People are going to love this.

Thanks man, glad you like it! It's all open source if you want to have a look? https://github.com/fallaciousreasoning/topo

The website works offline too, but I've been playing with making a native wrapper on Android: https://play.google.com/store/apps/details?id=nz.topos.twa
