• Imagery data for the Vegetation Mapping Inventory Project of Indiana Dunes National Lakeshore

    Metadata Updated: March 17, 2021

    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.

    Sixty-seven map classes were developed to map the vegetation and general land cover of INDU and environs, with 56 of them representing vegetation types at various levels in the NVC (association, alliance, and formation). The other 11 map classes depict general land cover; 4 representing non-vegetated land cover and 7 representing developed areas. Features were interpreted using high-quality stereoscopes over light tables and 1:12,000-scale color infrared (CIR) aerial photographs dated October 2004 (fall leaf-change). Polygon units were mapped to 0.5 ha (1.25 acres) minimum mapping unit (MMU) and, for specific wetland map units within the West unit, to 0.1 ha (0.24 acres) MMU. Another set of 1:6,000-scale CIR aerial photographs dated October 2004 were used to aid interpretation mapping of the West unit’s MMU. An ancillary set of 1:12,000-scale true color aerial photos dated April 2005 (leaf-off) covering the entire Lakeshore lands were used for additional reference during mapping.
