Niwot Ridge LTER

High-resolution imagery and DEMs are now available for the Niwot Ridge LTER and Green Lakes Valley CZO areas. The ten orthophoto mosaics span seven decades — from 1938 to 2008 — at 1.0 m to 30 cm resolution. Also available are four DEMs at 30 m to 2 m resolution. This data release will be useful for a variety of environmental research, including time-series analysis of climate-related changes in vegetation, hydrology, geomorphology, etc. The datasets should also be useful for visualization, mapping, modeling, and other objectives tied to science planning, land management, research, education, and outreach.

1938-2006 Orthoimagery and DEMs

These imagery and DEM data sets are in the public domain and can be downloaded from the
NWT LTER site.

2008 Orthoimagery

The 2008 imagery is embargoed until February 2011 and is not in the public domain. The 2008 imagery is available to NWT LTER and Boulder Creek CZO participants only. If you are a member of NWT LTER and/or Boulder Creek CZO, please download and fill out form (download pdf), and send to the NWT LTER data manager (lternwt@colorado.edu). The 2008 imagery will be made available through a DVD which must be picked up at the NWT LTER data manager's office.
