Imagery data for the Vegetation Mapping Inventory Project of Apostle Islands National Lakeshore
2010. Imagery data for the Vegetation Mapping Inventory Project of Apostle Islands National Lakeshore
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. Features were interpreted by using high-quality stereoscopes over light tables and 1:12,000-scale, color-infrared aerial photographs dated October 2004 (during fall leaf change). Polygon units were mapped mostly to a 0.5-ha minimum mapping unit. An ancillary set of 1:24,000-scale, true-color aerial photos dated April 2005 (during leaf-off conditions) covering the entire APIS lands were used for additional reference during mapping. The interpreted data were digitally and spatially referenced, making the spatial database layers usable in a geographic information system.
