Photogrammetric Mapping at Three Sites in Wupatki National Monument

EnviroSystems conducted architectural mapping of three sites at Wupatki National Monument, part of Flagstaff Area National Monuments, Coconino County, Arizona. The Monument required scaled planimetric drawings and cross-sections of standing architecture at WS323/Small Tower, WS1027/Cloud House, and WS1762/Coyote Water. As an alternative to aerial imagery, laser scanning, and traditional field mapping techniques photogrammetric methods were employed to create a 3D model of the structures at each site. 

Archaeological Geophysical Survey of the Tidball Property, Fort Hunter Liggett

EnviroSystems and Gulf South Research Corporation (GSRC) conducted a geophysical survey of the property surrounding the Tidball Store Site, CA-MNT-794H, at Fort Hunter Liggett, California. The  investigation used Ground Penetrating Radar (GPR) to cover a total of 0.78 acres at half-meter traverse spacing in an effort to better identify and interpret several anomalies that may represent historic features.

Vegetation Inventory Study for Land Management District 5, Units 1, 2, and 3 in Coconino County, Navajo Nation, Arizona

The Western Navajo Agency, Bureau of Indian Affairs, contracted EnviroSystems to monitor established range transects and current utilization. The application of geoprocessing techniques was employed to obtain useable acreage for livestock grazing within 1 and 2 miles of reliable water sources. Combining soils types, slopes, and buffer distances within certain grazing compartments determined the appropriate stocking rate and useable potential livestock and wildlife forage in relation to available water in an arid environment.
