This datalayer represents the indexing scheme for the 1:10,000 Coastal Color Orthophotos. The polygons in this index coverage were extracted from the statewide orthophoto index coverage for which color orthophotos are available, for both the mainland and island regions. Mass. Coastal Zone Management developed the layer. The six-digit orthophoto ID is stored in the character field TILE-NAME and in the integer field SHEET-ID.MassGIS maintains this layer. See the Coastal Color Orthophotos Index Map available at http://www.state.ma.us/mgis/ix_coq.htm.
