Description
Summary:The Toolik Field Station GIS (geographic information system) Department (ToolikGIS) has contracted the collection of aerial photographs of high-use research areas around Toolik Field Station during years 2002, 2007, 2013 and 2018. The aerial photographs were collected from small fixed wing aircraft during the summer months of July or August. Each photograph consists of a red, green, and blue spectral band. Photographs of each research area were collected with a high degree of front and side overlap. The overlapping photographs of each research area, by year, were merged using Adobe Photoshop, photogrammetry and/or GIS software. When available, GNSS (Global Navigation Satellite System) data were used during processing to create spatially referenced and terrain-corrected orthophotographic mosaics (ie, orthophotos). ToolikGIS uses orthophotos to help scientists select new research sites and support terrestrial change detection analyses. This orthophoto collection was created to serve primarily as a basemap in a ...
