This polygon feature class represents vegetation communities mapped at Canyonlands National Park. The polygons were generated using guidelines set by the Standardized National Vegetation Classification System (October 1995). A combination of methods were used to map Canyonlands. The USGS used e-Cognition software to create segments. The segments created were then looked at and extensively edited by the vegetation mappers. Some mapping was done on screen, using the 2002 imagery. Hard copy 9X9 photography was used for photo interpretation. 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...
This polygon feature class represents vegetation communities mapped at Hovenweep National Monument. The polygons were generated using guidelines set by the USGS-NPS Vegetation Mapping Program (http://www.usgs.gov/core_science_systems/csas/vip/standards.html). Original vegetation map unit lines were drawn on mylar overlays of the project photography, then scanned to generate the linework. Due to the "snapshot" nature of the aerial photography, this vegetation layer largely reflects conditions that existed when the imagery was collected (August 1996).
This polygon feature class represents vegetation communities mapped at Natural Bridges National Monument. The polygons were generated using guidelines set by the Standardized National Vegetation Classification System (October 1995). Original lines were drawn on a mylar overlay of printed 1:12,000 digital scale orthophoto quadrangles (DOQ), collected the summer of 2002. Hard copy 9X9 photography was used for photo interpretation. 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. The lines...
