Imagery for the Vegetation Mapping Inventory Project of National Park of American Samoa
2012. Imagery for the Vegetation Mapping Inventory Project of National Park of American Samoa
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. Quickbird, Ikonos, Worldview2 and digital airborne optical and lidar imagery of NPSA were obtained from NOAA and the US Department of Agriculture – National Resource Conservation Service (USDA - NRCS). The imagery was segmented in eCognition software and both the imagery and the segments were taken to the field to support the calibration trip. Following the calibration trip, KGA labeled the segments using the imagery, ancillary data sets, and classification and regression tree analysis to create a preliminary map.
