[Talk-us] TopOSM Colorado

[Bill Ricker]

> TopOSM-CO has a few important differences from TopOSM-MA:

What, MASSGIS doesn't cover Aspen?

> * Color-by-elevation in base layer.

interesting

> * Contour lines and hillshading generated from NED [1].

does that mean you're interpolating lines from a grid?

> * Hydrography (lakes, rivers, wetlands etc) from NHD [2].

which will eventually be in OSM

> * The hillshading, contour lines and map features are on separate
> layers. Use the layer switcher (top right "+") to toggle.

AWESOME. that's beautiful.

> Since the data is nationwide, the same technique could (theoretically)

requiring only a render farm plus some config ?

Use any perl in ingesting or anything?
