A broadly collaborative effort is nearly complete for creation and distribution of high-quality geospatial datasets to benefit research concentrated near Barrow, northernmost Alaska. The data include: OrthoRectified Radar Imagery (ORRI, 1.25 m pixels), a Digital Elevation Model (DEM, 5 m grid cells with <1 m vertical accuracy), and QuickBird satellite imagery (70 cm panchromatic; 2.8 m multispectral). The airborne-radar and satellite imagery were successfully acquired in late July and early August, 2002. The data are currently being finalized by Intermap Technologies and DigitalGlobe. Release at full-resolution to NSF-funded researchers, and at reduced-resolution to the public, is expected by December, 2003 ( see http://instaar.colorado.edu/QGISL/barrow_high_res ).
The spatial datasets are more precise, accurate, and useful than previously available data layers. The state-of-the-art, remote-sensing products will overcome obstacles of differing map projections, datums, resolution, extent, timeframe, accuracy, data format, and accessibility. The data will provide a long-lasting, common base for orthorectifying and georegistering other GIS data and imagery, and will establish a temporal baseline for decades of change-detection studies. Beyond education and outreach, the data should promote quantitative analysis, modeling, and collaboration in the fields of: ecosystem classification, health, & dynamics; terrestrial-atmospheric fluxes of greenhouse gases; natural & anthropogenic landscape dynamics; archeology; stream and thaw-lake hydrology & change; coastal flooding; coastal erosion; permafrost melting; and other environmental responses to unprecedented arctic warming. These societally relevant topics can be addressed in new ways and with greater success using shared digital topography and imagery.
