Clark Labs offers archives of global data, pre-processed for immediate analysis and mapping within the IDRISI Selva GIS & Image Processing software.
The data archives are very well-suited for the Earth Trends Modeler application included within the IDRISI Selva software. Earth Trends Modeler is a vertical application used to explore and analyze trends and dynamics in image time series data. It is therefore especially useful for those researching global climate change and ecosystem impacts.
All of the data in this series are in IDRISI format. For each archive, vector global country-level boundaries are also provided.
Data Archive 1 is provided on DVD. All other Data Archives are provided on CD.
Global Data Archive 1: 0.05 Degree MODIS Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI 2000 - 2009)
The data in this archive were processed by NASA Goddard from the Terra sensor projected on a 0.05 degree Climate Modeling Grid (CMG). The original values were not altered. Dates include February 2000 through January 2010. All files are provided in the latitude / longitude reference system. Archive size is 11 GB.

Global Data Archive 3: 1 Km Global Elevation Model
GTOPO30 global coverage digital elevation model (DEM) in IDRISI format at 30-arc second resolution. Data is provided in the latitude / longitude reference system. The GTOPO30 data files were downloaded from the USGS EROS Data Center. The original tile division (33 pieces), projection, data definition, and spatial resolution are maintained in the converted files. Archive size is 280 MB. Download size is 274 MB.
