Vegetation - Sequoia and Kings Canyon National Parks Vegetation Mapping Project [ds984]

The Vegetation Map of Sequoia and Kings Canyon National Parks was produced over an eight year period (2000-2007) to describe and map the vascular plant associations of the two southern Sierra Nevada national parks. Over 80,000 individual vegetation polygons are mapped to 172 vegetation classes.

Overall spatial accuracy of the resulting map products is equivalent to 1:24000 National Map Accuracy Standards. Vegetation delineations are based on photo interpretation of 1:15,840 scale color infrared photography acquired by Pacific Western Technologies (PWT) during two missions conducted in July of 2000 and 2001. Photo interpretation and automation, including rectification to the 1:24000 Digital Photo Orthoquads (DOQQs) was performed by Aerial Information Systems (AIS) under subcontract to Environmental Systems Research Institute (ESRI), who provided project management and final cartographic products.
