Overview

The Massachusetts Coastal Zone Management Program has developed an index to identify the geographic bounds, name and identification number for a series of MCZM published maps. Each tile measures 8,000 by 10,000 meters. The tile orientation is in both landscape and portrait. This tile scheme allows for plotting at a scale up to 1:10,000 in a single panel on a HP 755 device. The layer is named CZMSHEET_POLY.  See the Index Map pdf format of ix_shch.pdf .

Methodology

A polygon coverage was developed from keyboard entered coordinates. The geographic bounds of each tile are located on an increment of 2,000 meters.
