Providing geospatial support for Alaska
GINA and the National Park Service worked together to develop a MODIS-derived NDVI metrics algorithm. The data products from this project are available as a Web Coverage Service (WCS) with MODIS-derived yearly NDVI metrics. The data coverage includes the entire state of Alaska for the years between 2000 and 2016.
The NDVI metrics algorithm uses eMODIS data provided by the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center. The data can be downloaded from the USGS-EROS eMODIS website.

The algorithm takes 7-day composite eMODIS NDVI data, performs data stacking, interpolating, smoothing, and then calculates the NDVI metrics. 12 metrics are produced by the algorithm:
The NDVI metrics algorithm technical document is available online.
The 12-band metrics files are accessible through the WCS server at URL: http://ndvi.gina.alaska.edu/metrics/emodis? The 5-band metrics files which includes band 1, 3, 5, 6, and 12 are also provided at WCS server URL: http://ndvi.gina.alaska.edu/metrics/emodis_5bands?
The 12-band NDVI metrics are also available through GINA's http server at http://static.gina.alaska.edu/NPS_products/eMODIS_NDVI/eMODIS_derived_NDVI_metrics/version_1.0/
