Documents in this repository pertain to usage of the MODIS Subsetting Tools and Services maintained by the ORNL DAAC. MODIS data hosted at the ORNL DAAC can be accessed in three ways:

1. Global Subsetting and Visualization Tool
   Request a subset for any location on earth, provided as GeoTiff and text format, including interactive time-series plots and more. Users specify a site by entering the site's geographic coordinates and the area surrounding that site, from one pixel up to 201 x 201 km.

2. Fixed Sites Tool
   Download pre-processed MODIS subsets for 1100+ field sites for validation of models and remote sensing products. The goal of the MODIS Subsets for Selected Field Sites is to prepare summaries of selected MODIS Land Products for the community to characterize field sites.

3. Web Service
   Retrieve subset data (in real-time) for any location(s), time period and area programmatically using a SOAP Web Service (from 1 pixel up to 201 x 201 km). Web Service client and libraries are available in multiple programming languages, allowing integration of subsets into users' workflow.
