The SNEP Project compiled a large amount of existing geographic data and information pertaining to the Sierra Nevada ecosystem. This material ranged from digital maps and images that spanned the entire region to analog maps and data tables for local areas, and also included original data, maps, and model outputs generated by SNEP scientists and consultants. A technical support team was assembed to integrate this information into a coherent, well-documented database and to assist the Science Team with data compilation, data quality assessment, analysis, and product generation.
