The Aqueducts layer contains linework representing water-transporting conduits from 1:100,000 U.S. Geological Survey Digital Line Graph (DLG) files, with additional linework added by the Massachusetts Water Resources Authority. In ArcSDE the layer is named AQUEDUCTS_ARC. Annotation for MWRA aqueducts is stored as AQUEDUCTS_ANNO_DESC.

Methodology

USGS DLG files were converted to ArcInfo coverage format. MWRA staff digitized additional aqueduct linework and created annotation.
