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. Vegetation and land use were interpreted to as detailed a level possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated directly on-screen through heads-up digitizing using ArcGIS editing tools and transferred to a spatial database. The project used the program standard minimum mapping unit of 0.5 ha with few exceptions.

Orthophotos, raw imagery, and scanned aerial photos are common files held here. Vegetation and land use were interpreted to as detailed a level as possible from high-resolution, 9” x 9” stereo pairs of 1:12,000-scale true color aerial photography. Polygons representing vegetation or land use map classes were delineated on Mylar overlays on aerial photographs (where signatures were confusing) and with the heads-up digitizing technique (where signatures had high contrast), then transferred to a spatial database. The project used the national program standard minimum mapping unit of 0.5 ha with few exceptions.

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. Since SAAN represented a fairly small and accessible site no new imagery or aerial photography was acquired. Instead, existing sources of imagery were evaluated and three NAIP products were selected. These included the 2003, 2004, and 2005 NAIP ortho-photos. The 2003 and 2004 imagery had 1-meter resolution and the 2005 had 2-meter resolution and all were acquired at 1:12,000-scale. The 2003 and 2004 were acquired in color infrared format and the 2005 was true color. 2005 - 1:12,000-scale true color ortho-rectified imagery, compressed county mosaic, 2 meter pixel resolution 2004 - 1:12,000-scale color infrared digital ortho-imagery, compressed county mosaic, 1 meter pixel resolution 2003 - 1:12,000-scale color infrared digital ortho-imagery, compressed county mosaic, 1 meter pixel resolution

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. Photointerpreters delineated initial polygons through manual interpretation of 2003/2004 1:12,000-scale true color aerial photography supplemented by occasional computer screen digitizing on a mosaic of digitized aerial photos. These polygons were labeled with base map classes during photointerpretation. Field visits verified interpretation concepts.

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. Two sets of digital orthophotography were used in the vegetation/land use mapping process after the 2003 field season: (1) a digital orthophoto mosaic that is referred to as the Battlefield Unit photomosaic and (2) digital orthophotography of the Schuyler House, Saratoga Monument, and Victory Woods areas, located approximately seven mi (11.3 km) north of the Battlefield Unit, referred to as the Old Saratoga Unit orthophotography.
