HTTP Interface

All LAADS DAAC products are available at no charge through our download site at https://ladsweb.modaps.eosdis.nasa.gov/archive. The directory structure is as follows:

allData/<collection number>/<product name>/<year>/<day of year>/<file name>

+ Browse LAADS HTTP data downloads

Open Geospatial Consortium (OGC)

The OGC (Open Geospatial Consortium) is an international not for profit organization committed to making quality open standards for the global geospatial community. These standards are made through a consensus process and are freely available for anyone to use to improve sharing of the world's geospatial data.

Web Coverage Service (WCS)

Access data via an application programming interface (API) and the internet by specifying product, geographic, and temporal coverage information.

For the specification, see OpenGIS Web Map Tile Service Implementation Standard.

For information on using a WCS to connect to LAADSWeb and search for and stream back data, see MODAPS Web Coverage Service (WCS) API.

OPeNDAP

The MODIS and VIIRS products in LAADS are available through our OPeNDAP service, which can be accessed at MODAPS Web Coverage Service (WCS) API. The directory structure is identical to that of the web site:

allData/<collection number>/<product name>/<year>/<day of year>/<file name>

+ Browse LAADS OPeNDAP site

OPeNDAP allows data to be downloaded in several formats, such as NetCDF, and allows data to be subset. The following URLs provide examples of how OPeNDAP can be used to download data:

Download data from day 65, year 2013, ESDT MOD03, and ArchiveSet 6 in NetCDF format but only include the Scan_Offset variable in a range of 0 to 4059 with a stepping of 1 in the first dimension and a range of 0 to 2707 with a stepping of 1 in the second dimension.

Webification (W10N)

Webification (W10N) is an enabling technology that simplifies the use of data on the web platform. The core idea of Webifcation is to make the inner components of resources directly addressable and accessible via well defined and meaningful URLs.

LAADS Web Service (LWS) Classic

LAADS Web Service Classic is a SOAP and REST based Application Programming Interface (API) that allows users to search, order, and download MODIS Level-1 and atmosphere data products through a programmable interface.

Full Year Download

A shell script that allows one to download an entire year's worth of data by swapping out values for product, collection, and year.

LAADS Data Download Scripts

Example scripts for batch downloads via a command-line interface (CLI) or other scripting languages such as Shell Script, Perl, and Python.

stage_MODIS.pl

An example perl script that uses SOAP protocol to talk to LAADS Web Service (LWS) Classic. Allows one to search for and download LAADS data from the LAADS HTTP archive tree by product name, collection, date range, and area of interest.
