Massachusetts (Orthophoto Index, 2005)

Description
The Digital Orthophoto Index layer is a 4,000 by 4,000 meter grid which serves as an index for the statewide digital orthophotos and scanned USGS QUad images, as well as other datalayers. The layer is named OQMAIN_POLY. The naming convention for each grid cell is based on the NAD83 meters coordinate pair for the lower right corner of the cell. The Grid ID is composed of the first 3 digits of each coordinate in this xy pair. For example, a grid cell with xy coordinates of 253000m 942000m at the lower right corner would have an ID of 253942.
