Development of environmental data set of taklimakan desert
Abstract
Using the data observed with TERRA/MODIS over Taklimakan Desert in western China during the months of March 2003 and April 2002 the environmental data set of 1km spatial resolution is made. MODIS has 36 bands ranging from visible to thermal infrared spectra. In this research the data of six bands ranging from visible to the so called short-wave infrared spectra which are compatible to Landsat-7 ETM+ were selected and utilized. The reason of the selection is that the data of these bands are most effective for the retrieval of the land surface information. Another reason is to compare the MODIS data with that of high spatial resolution TM data to explore the effect of difference of the spatial resolution. The study is made also the effect of difference of observing direction and time utilizing Aqua/ MODIS data which were acquired on the orbit of ascending mode. Aqua/MODIS make observation at approximately 2 hours later in the ascending mode orbit therefore the angle between the observation and solar incidence of Aqua/MODIS is different from that of Terra/MODIS. Taking the result of the study on various effects into account the data set has been made. Needless to say that the clouds were eliminated using multiple data.
