Imagery data for the Vegetation Mapping Inventory Project of Hot Springs 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. The mapping component was produced by identifying land cover on air photos and hand digitizing on-screen. Heads-up digitizing was accomplished at a display scale of not more than 1:1,000 against a back-drop of air photos. This included 2010 leafon true color and 2006 leaf-on color infrared images (Figure 5). Additionally, georeferenced aerial photography from the 1940’s, 1960’s, 1980’s, and 1990’s were used to identify areas where previous disturbance had occurred, including demolished buildings, old roads, clearings, and historical timber harvest sites. Hot Springs National Park = 5,465 acres (2,211.8 hectares) Base Imagery used for mapping (acquired by MoRAP): 2010, Arkansas County, AR, leaf-on, true color, 1m 2006, Arkansas County, AR, leaf-off, CIR, 1m Additional Imagery acquired and viewed by MoRAP: SPOT, leaf on SPOT, leaf off
