Summary
This polygon feature class represents vegetation communities mapped at Golden Spike National Historic Site. The polygons were generated using guidelines set by the Standardized National Vegetation Classification System (October 1995). Vegetation polygons were drawn on-screen using the aerial 2006 photography. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow. Additional data layers were used in aiding the interpretation, such as slope, hydrology, geography, and ground-collected vegetation information. As with any digital layer, this layer is a representation of what is actually occurring on the ground at the time the imagery was acquired (August 2006). [...]

As with any digital layer, this layer is a representation of what is actually occurring on the ground at the time the imagery was acquired (August 2006). Errors are inherent in any interpretation of ground qualities.
This polygon layer represents vegetation communities found at Golden Spike National Historic Site. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation.
