Waltermire, and A. Cully 2009 report doi:10.5066/F71834DV The Canyon de Chelly National Monument Accuracy Assessment Observation Location executable shapefile (cachaa.exe) was developed as a Geographic Information Systems (GIS) product in the Canyon de Chelly National Monument Vegetation Classification, Distribution, and Mapping project. Its spatial extent covers Canyon de Chelly National Monument and an approximately 1 kilometer buffer around the park boundary (park environs). This executable shapefile maps sites where accuracy assessment observations were made for the vegetation mapping project conducted at Canyon de Chelly National Monument. Original field data is documented in the accompanying Access database, cachdata.mdb. 2006 ground condition Complete None planned Canyon de Chelly National Monument and environs -109.558111 -109.129030 36.296622 35.984012 none USGS/NPS Vegetation Mapping Program National Park Service Vegetation Map Accuracy Assessment points none Canyon de Chelly National Monument CACH Cortez Apache County northeast Arizona Four Corners Region Arizona AZ Southwestern United States Western United States United States North America None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae plants None None Lisa Thomas Southern Colorado Plateau Network Coordinator/Ecologist mailing address

Cully 2009 executable shapefile Thomas, K.A., M.L. McTeague, L. Ogden, K. Schulz, T. Fancher, R. Waltermire, and A. Cully 2009 report Unknown Shapefile covers the entire park and park environs (1 kilometer) Field observers recorded the geographic coordinates of accuracy assessment locations visited in the field. These coordinates were entered into an Access database and imported into GIS to develop the accuracy assessment shapefile. Accuracy assessment locations were chosen to represent a statistical sample of all mapped base map classes. The number of locations and method of determining location placement within the polygon is described in section 4.1.1 Field Sampling Design of the project report. The field observers made observations at 806 locations as recorded in the associated database cachdata.mdb; however, 24 of the locations lacked sufficient geographic data to be included in this shapefile. In addition accuracy assessment points were not used in the analysis if the points were sampled remotely with binoculars, if the GPS location recorded had very large error due to poor satellite coverage, or if the GPS error exceeded the distance of the observation location to the nearest polygon edge. A total of 636 locations were used in the final accuracy assessment; the locations used are indicated in the shapefile field 'Analysis'. Unknown Accuracy assessment sites were not used to develop accuracy assessment statistics if the sampled polygon was less than 0.5 ha in size, multiple sites were erroneously sampled in the same polygon, or the sample waypoint was too close to the polygon boundary to ensure that the assessment was not of a transition zone. Unknown Accuracy assessment sites were not included in the shapefile when the geocoordinates of an observation site were missing or corrupted and could not be recovered from the field data forms.
