A client for the NASA MODAPS web service

Project description

Python RESTful client for NASA’s MODIS Adaptive Processing System (MODAPS) data archive at the Level-1 and Atmosphere Archive & Distribution System (LAADS) Distributed Active Archive Center (DAAC).

MIT License.

Installation

pip install modapsclient

pygaarst.modapsclient

This is a REST-full web service client that implements the NASA LAADSWEB data API (see https://ladsweb.modaps.eosdis.nasa.gov/tools-and-services/lws-classic/quick-start.php)

class ModapsClient(object)

Usage:

from pygaarst import modapsclient as m
a = m.ModapsClient()
b = a.[methodname](args)

Implements the methods from http://ladsweb.nascom.nasa.gov/data/api.html , except for (currently) those related to OpenSearch (which don’t appear to be working reliably server-side) and ordering (TBD). Implemented methods are marked with an x.

Caveats and limitations

This API is listed as “classic” by NASA EOSDIS, so it’s unlikely it’ll receive much attention in the future. Hardly anyone will use the “order” feature as the files are usually available on the public file server. For these two reasons, the unimplemented functionality is also unlikely to ever be implemented.

>From experience, products listed via listProducts are not necessarily in actual fact available in the NASA EOSDIS LAADS archive. In this case, you may receive an error when searching for files.

The MODAPS web service has the tendency to return a 500 Internal Server Error for any error, including unsupported values for query string variables.
