Nominatim vs Queimadas INPE

Nominatim provides worldwide forward and reverse geocoding built entirely on OpenStreetMap data, needing no API key — only a descriptive User-Agent or Referer header identifying the calling application. The public instance at nominatim.openstreetmap.org is a free courtesy service, not a commercial product: its usage policy caps requests at 1 per second, forbids autocomplete-style querying and bulk/parallel scripts, and requires caching results rather than re-fetching them. Heavier users are expected to self-host Nominatim against their own OSM extract instead of relying on the shared instance.

Queimadas is Brazil's national fire-hotspot monitoring program run by INPE (National Institute for Space Research), publishing daily, monthly, and annual satellite-detected fire-focus data plus fire-risk meteorology layers as open downloads rather than a query API. Files are served as CSV, KML, and shapefile/GeoTIFF layers from INPE's data server with open CORS headers, free and keyless.
