The US government shutdown has now rippled all the way into Gaia GPS! Two non-essential services we use from the USGS (their elevation lookup API and the National Map) are currently not functioning.
You can see the official notice on the USGS site. Thankfully the charts we feed into our NOAA charts app Skipper from the government are deemed too critical to take down for the purpose of political theater.
In the meantime, we’re going to switch our elevation look-ups to use a commercial API for v8.1, which will have the added benefit of working internationally. The National Map will just have to wait until Uncle Sam and all of his besuited lackeys in Washington decide to do their jobs, but there are of course many analogs for this map source in Gaia.
