Keywords: MODIS, web service, R, SOAP


The tutorial outlined in the jupyter notebook will explore using the MODISTools library in R to access MODIS Land Products through a standards based SOAP (Simple Object Access Protocol) Web Service hosted by the ORNL DAAC.

Using the MODIS Web Service users can:

  • Retrieve MODIS subsets through command line operations
  • Download and integrate subsets directly into client-side workflows
  • Download and visualize subsets with customized code
    ... and much more.

This tutorial will demonstrate how to do the following in R:

  • build a time series of MOD11A2 land surface temperature from multiple web service requests
  • format subset responses for easy integration in R workflows
  • perform quality control filtering based on MODIS qc criteria
