Section titled “Sources”Most of what Vertex serves is US government data in the public domain. A few sources carry their own terms, which pass through to you:
| Data | Source | Obligation |
|---|---|---|
| HRRR, RRFS, NAM, GFS models; MRMS radar and lightning; NWS alerts and discussions; USGS gauges and elevation; PAD-US lands; FAA airspace and TFRs; USFS motor-vehicle-use maps | NOAA, USGS, FAA, USFS, USDA | None. |
ECMWF IFS (models=ecmwf) |
ECMWF open data, CC BY 4.0 | Credit “ECMWF” where shown and note that derived layers are modified from the source. |
| Station observations | NOAA MADIS and the provider named on each station (MesoWest, RAWS, CWOP, SNOTEL, HADS, METAR) | Show the provider name with a station’s data; do not represent data as an official NOAA product. |
Trails (trails-mt), peaks, and any layer whose metadata says ODbL |
OpenStreetMap contributors, ODbL | “© OpenStreetMap contributors” wherever displayed. Derived databases you publish from these layers inherit the ODbL. |
| Wildfire hotspots | NASA FIRMS | “Hotspots: NASA FIRMS” is appreciated. |
The attribution field in /v1/layers, TileJSON documents and static-layer metadata carries the right string per layer; render it in your map’s attribution control and you are covered.
