erddapy: ERDDAP + Python

Easier access to scientific data

erddapy takes advantage of ERDDAP’s RESTful web services and creates the ERDDAP URL for any request like searching for datasets, acquiring metadata, downloading data, etc.

What is ERDDAP?

The Environmental Research Division’s Data Access Program (ERDDAP) is a data server that provides a consistent way to download subsets of scientific datasets.

There are many scientific data server available, like OPeNDAP, WCS, SOS, OBIS, etc. They all have their advantages and disadvantages, ERDDAP goal is to fill the gaps and unify most of the advantages in a single service. The main advantages of ERDDAP are:

  • offers an easy-to-use, consistent way to request data via the OPeNDAP;
  • returns data in the common file format of your choice, .html table, ESRI .asc and .csv, Google Earth .kml, OPeNDAP binary, .mat, .nc, ODV .txt, .csv, .tsv, .json, and .xhtml, and even some image formats (.png and .pdf);
  • standardizes the datetimes where string times are always ISO 8601:2004(E) and numeric times are always uses “seconds since 1970-01-01T00:00:00Z”;
  • acts as a middleman by reformatting the request into the format required by the remote server, and reformats the data into the format that you requested.
