Imagery data for the Vegetation Mapping Inventory Project of Great Basin National Park
2007. Imagery data for the Vegetation Mapping Inventory Project of Great Basin National Park
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. GRBA base map imagery included a 4-band, 1-meter resolution, 2007 Digital Globe product and a 4-band, 6-inch resolution product acquired in June and July 2007 by Digital Mapping, Inc. (DMI) for the Southern Nevada Water Authority. Interpretation and mapping of the vegetation began using a four step process involving: (1) preliminary image classification and segmentation, (2) photo-interpretation and digitizing, (3) ground-truthing of the mapped data, and (4) map refinement and finalization.
