|Download these layers (ESRI Shapefiles):|
- 1-minute graticule
- 10-minute graticule
These two layers are meant to be used for general planning, cartographic display and educational purposes.
- MINLL1_ARC - 1-minute latitude-longitude lines
- MINLL10_ARC - 10-minute latitude-longitude lines
MassGIS used Arc/Info Workstation to GENERATE lines in NAD83 Decimal-Degrees coordinates using the FISHNET option, which were then projected to the Mass. State Plane NAD83 Meters Mainland coordinate system.
The MINLL10_ARC attribute table contains these items:
The MINLL1_ARC attribute table does not contain any items other than those standard in an arc attribute table.
LATITUDE Latitude value of the line ("NA" if line is longitudinal) LONGITUDE Longitude value of the line ("NA" if line is latitudinal) LINE_0 Indicates whether the line is a 00 seconds line (i.e. 44 00 00)
MassGIS is maintaining these layers.
In July 2005 these layers were re-created based on the production method described above. The previous versions were created based on NAD27 coordinates and were projected to NAD83, resulting in a slight shift from the features' true locations.
