These two layers represent the graticule of latitude and longitude linework covering Massachusetts
|Download these layers (ESRI Shapefiles):
- 1-minute graticule
- 10-minute graticule
- MINLL1_ARC - 1-minute latitude-longitude lines
- MINLL10_ARC - 10-minute latitude-longitude lines
ProductionMassGIS 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.
AttributesThe MINLL10_ARC attribute table contains these items:
|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.
