Geospatial data for the Vegetation Mapping Inventory Project of Puukohola Heiau National Historic Site
공공데이터포털
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. For PUHE, 31 map units (14 vegetated, five geologic, and 12 land-use/land-cover) were developed . The final list of map classes/units was directly crosswalked to corresponding plant associations and land use classes. PUHE map classes represent a compromise between the detail of the rUSNVC, resource management needs, and the limitations of the imagery. As a result, the mapping legend does not exactly match the rUSNVC. In most cases the rUSNVC and Park Special associations were used as map units. The interpreted and remotely sensed data were converted to Geographic Information System (GIS) databases and maps were printed, field tested, reviewed, and revised. The final map layer was accessed for thematic accuracy by overlaying 57 independent accuracy assessment points. The final overall accuracy of the map layer was determined to be 97% with a Kappa value of 82%

Imagery data for the Vegetation Mapping Inventory Project of Puukohola Heiau National Historic Site

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. Once the boundary was finalized copies of 2006 Quickbird Imagery were obtained from the PACN. This imagery was obtained as pan-sharpened, cloud-free, 4-band, 0.6-meter resolution digital ortho-photos that covered the entire island of Hawai‘i. The specific imagery tiles covering the PUHE project area were selected, clipped and mosaiced to provide the basemap for mapping purposes. In addition to the Quickbird imagery, 1-meter, 3-band (true color) 2002 Ikonos imagery was also obtained for PUHE, but due to cloud cover and ensuing changes at PUHE since 2002 this product was only used in an ancillary role.. By comparing the signatures on the imagery to field and ground data, 31 map units (14 vegetated, five geologic, and 12 land-use/land-cover) were developed and directly crosswalked or matched to their corresponding rUSNVC plant associations.
