Abstract
ArcGIS Assessment of MODIS NDVI for High Temporal Frequency Monitoring Track: Remote Sensing Imagery Author(s): Theresa Watson, Richard Watson, Crystal Krause, Louis Scuderi, Enrique Montaņo The MODIS (MODerate Resolution Imaging Spectroradiometer) sensors onboard the NASA Earth Observing Satellites provide the opportunity to assess environmental change at high temporal frequencies over spatial extents previously not readily attainable. Research at the University of New Mexico's Center for Rapid Environmental Assessment & Terrain Evaluation (CREATE) is seeking to analyze vegetation change at higher temporal frequencies than are currently possible using the static 16-day NDVI products available through the NASA DAAC. ArcGIS plays a central role in the development and assessment of four- and eight-day composites for areas having low cloud cover and for a separate, continually running product or "Running NDVI." Higher frequency vegetation indices and running indices will allow the comparison of vegetation data with other environmental factors such as precipitation and storm damage that occur over shorter temporal intervals than the current static products.
