Landsat and MODIS data for the Lower Gwydir Catchment study site


The Lower Gwydir Catchment study site is located in northern NSW (149.2815E, 29.0855S), where 14 cloud–free Landsat-MODIS pairs were available from April 2004 to April 2005. Gwydir is 80 km N–S and 68 km E–W covering 5,440 km2 (3200 columns by 2720 lines at 25 m resolution). All Landsat imagery are TM acquired by Landsat-5. A sepa... more

The Landsat imagery were atmospherically corrected using Li et al.’s (2010) algorithm (see the citation below). Geocorrection was defined using the Geocentric Datum of Australia 1994 (GDA94). MODIS Collection 5 data were acquired by Terra only, specifically MOD09GA downloaded from the USGS DAAC (ftp://e4ftl01.cr.usgs.gov/MOLT/, during Sep 2011). MODIS data were geometrically transformed from the USGS DAAC supplied tiles which have a sinusoidal projection to WGS84 using the MODIS Reprojection Tool (https://lpdaac.usgs.gov/lpdaac/tools/modis_reprojection_tool, accessed 27 Sep 2011). MODIS data were unprojected and referenced to World Geodetic System 1984 (WGS84) . Li, F., Jupp, D. L. B., Reddy, S., Lymburner, L., Mueller, N., Tan, P., & Islam, A. (2010).

About this Project

Legacy


Blending of Landsat-MODIS surface reflectances


The blending algorithms STARFM and ESTARFM were evaluated: (i) over the entire site; (ii) for subsets of specific land cover types.


Analysis


The Landsat imagery were atmospherically and geo-corrected. MODIS product MOD09GA was downloaded from USGS DAAC.
