1 U.S. Department of the Interior U.S. Geological Survey Discover MODIS Land at your Desk January 17, 2007 Calli B. Jenkerson* MODIS Science Data Specialist LP DAAC * SAIC, contractor to U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science, Sioux Falls, SD. Work performed under USGS contract 03CRCN0001.

2 Rumors  Better resolution than AVHRR  Better repeat cycle than Landsat  Free data  Too many products  Weird map projection  Hard to find  Can I use MODIS data in my application?
