pvlib.location.lookup_altitude#

pvlib.location.lookup_altitude(latitude, longitude)[source]#

Look up location altitude from low-resolution altitude map supplied with pvlib. The data for this map comes from multiple open data sources with varying resolutions aggregated by Mapzen.

More details can be found here https://github.com/tilezen/joerd/blob/master/docs/data-sources.md

Altitudes from this map are a coarse approximation and can have significant errors (100+ meters) introduced by downsampling and source data resolution.

Parameters
  • latitude (float.) – Positive is north of the equator. Use decimal degrees notation.

  • longitude (float.) – Positive is east of the prime meridian. Use decimal degrees notation.

Returns

altitude (float) – The altitude of the location in meters.
