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

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.

Attributes

The layer's polygon attribute table has the following items:

Item Name Width Output Type Comments
NUMBER 4 4 C Unique alpha-numeric code such as C-25
NAME 24 24 C Place name identifier for the individual sheet
LAYOUT 1 1 C L for Landscape
P for Portrait

Maintenance

MCZM maintains this data. Complete documentation on the Shoreline Change mapping project may be downloaded in MS Word 6.0 format ( shorech.doc )
