Imagery data for the Vegetation Mapping Inventory Project of Saugus Iron Works National Historic Site

Published by National Park Service | Department of the Interior | Metadata Last Checked: June 25, 2025 | Last Modified: 2006-06-28
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. High-quality existing photography developed by MassGIS was used as the base for the vegetation map (MassGIS 2007). A true color orthophoto mosaic was developed from a set of digital 1:5,000 scale medium resolution true color aerial images that are considered the new "base map" for the Commonwealth of Massachusetts by MassGIS and the Executive Office of Environmental Affairs (EOEA). The photography for the entire commonwealth was captured in April 2005 when deciduous trees were mostly bare and the ground was generally free of snow. The image type is 4-band (RGBN) natural color (Red, Green, Blue) and Near infrared in 8 bits (values ranging 0–255) per band format. Key information for the mosaic is summarized in Table 1. Appendix A contains additional detailed information regarding the aerial photography acquired from MASS GIS.
