Nearly Every USGS Topo Map For Free
A killer feature using this dataset would be an API to get ground-level elevation (above sea level) by passing a latitude and longitude pair. This exists in about 10 different APIs across the web already, but they're wildly expensive (or low-res). Google's is wrapped inside Maps for Business, which IIRC would cost far more than most startups can afford.Of course, we can get the data "for free" from the USGS. But then we'd have to host and query the data ourselves, which becomes...expensive. I wonder if there's an inexpensive solution out there, for high-res elevation APIs?
