Imagery data for the Vegetation Mapping Inventory Project of Hagerman Fossil Beds National Monument
공공데이터포털
This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. HAFO represented a fairly small and accessible site, no new imagery or aerial photography was deemed necessary for this project. Instead, existing sources of imagery were evaluated and 2 NAIP products were selected to be used as base maps. These included the 2004 and 2006 NAIP products. The 2004 products had 1-meter resolution and were acquired at 1:12,000-scale, which is adequate for vegetation mapping purposes. The 2006 product had 2-meter resolution and was acquired in true-color infrared format. The 2006 imagery was more recent than the 2004 and although it had a coarser resolution, it did highlight all of the recent changes to the landscape such as fires, new roads, tree removals, etc.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The FOBU vegetation mapping project area was divided into 1,709 polygons. A total of 1,687 map polygons represent 37 natural and semi-natural vegetation map classes. Two land use map classes describe 22 other polygons within the mapping area. Average polygon size across all map classes is 2.0 ha (5.0 acres). Natural and semi-natural vegetation classes cover 6,153 ha (15,205 acres; 98.7% of the project area). Land use polygons, including roads and NPS facilities, total 63.5 ha (156.9 acres; 1.3% of the project area). The most frequent vegetation mapping unit is the Low Sagebrush Shrubland (S-LOWS) with 646 polygons covering 2,161 ha (5,341 acres) or 35% of the project area.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Mapping and interpretation of JODA involved a five step process including: (1) field reconnaissance, (2) map class development, (3) image processing and interpretation, (4) draft map validation, and (5) spatial database development. Field reconnaissance was initiated by CTI and NMI staff in 2008 to quickly familiarize the mappers with the vegetation patterns and distribution at JODA. As the classification plot data were acquired later in 2008, feedback on the dominant and characteristic plant species was solicited from ORNHIC ecologists. boundary placement and labeling. Field notes were made directly on vegetation map copies and an additional 70 observation points were sampled to support the notations. Confusing sites were visited including the Picture Gorge area where shadows on the NAIP imagery prevented viewing the distribution of vegetation types. Ground data and ground photographs were collected to insure consistent mapping of confusing sites. Upon return to the office, minor updates of the draft vegetation map were completed prior to the AA task.
