  1. 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?

  26. http://lpdaac.usgs.gov/datatools.asp MODIS Reprojection Tool (MRT)

  27. http://lpdaac.usgs.gov/landdaac/tools/modis/index.asp

  28. MRT Capabilities Overview Reproject Sinusoidal to: • Geographic • Hammer • Mollweide • Sinusoidal • UTM • Transverse Mercator • Integerized Sinusoidal • Goode’s Interrupted Homolosine • Lambert Azimuthal • Lambert Conformal Conic • Polar Stereographic • Albers Equal Area -Spatial Subset -Mosaic -Spectral Subset -Outputs .hdf, .bin, .tif -Resampling -Datum Conversion

  29. MRT Capabilities Overview Sinusoidal Lambert Azimuthal

  30. MRT Capabilities Overview MODIS Reprojection Tool (MRT) Utility

  31. MRT Capabilities Overview Integerized Sinusoidal Lambert Azimuthal

  32. http://lpdaac.usgs.gov/datatools.asp MODIS Swath Reprojection Tool (MRTSwath)

  33. MRTSwath Overview Developed for Level-2 MODIS Land Data Provides same general capabilities as MRT except -Requires Geolocation input (Level 1A MOD03) -Does not include mosaic function

  34. MRTSwath Overview Level-2 Albers Level-2 Swath

  35. http://lpdaac.usgs.gov/datatools.asp MODIS Land Data Operational Product Evaluation Tools (LDOPE)

  36. MODIS LDOPE Tools • Perform any processing function necessary for manipulating MODIS Land data, except reprojection • QABits, mosaicking, subsetting, format conversion, multidimensionality, etc. • Stand-alone executables invoked from a command-line interface • Supported on Irix, Solaris, Linux, and Windows operating systems
