GIS Concepts: Map Projections / Coordinate Systems

Section: 51:3‐7: Official survey base established; plane co‐ordinates 

51:3‐7. The official survey base for New Jersey shall be a system of plane co‐ordinates to be known as the New Jersey system of plane co‐ordinates, said system being defined as a transverse Mercator projection of the Geodetic Reference System of 1980, having a 

t l idi 74` 30' t f G i h hi h idicentral meridian 74` 30' west from Greenwich on which meridian the scale is set at one part in 10,000 too small. All co‐ordinates of the system are expressed in meters, the x co‐ordinate being measured easterly along the grid and the y co‐ordinate being measured northerly along the grid, the origin of the co‐ordinates being on the meridian 74` 30' west from Greenwich at the intersection of the parallel 38` 50' north latitude, such origin being given the co‐ordinates x=150,000 meters; y=0 meters. The precise position of said system shall be as marked on the ground by triangulation or traverse stations established in conformity with the standards adopted by the National Geodetic Survey, formerly the United States Coast and Geodetic Survey for first and second‐order work, whose geodetic positions have been rigidly adjusted on the North American Datum of 1983 or the most recently published adjustment by the National Geodetic Survey, and whose plane co‐di t h b t d th t d fi d Th N

15

ordinates have been computed on the system defined. The New Jersey co‐ordinate system defined by the North American Datum of 1927 may be used concurrently with or in lieu of the system defined by the North American Datum of 1983 for a period of 36 months after the effective date of this amendatory act, P.L.1989, c.218. 

Standard conversions from meters to feet shall be the adopted standards of the National Oceanic and Atmospheric Administration.

GIS Analysis: Clip

• Extracts input features that overlay the clip features; use this tool to cut out a piece of one feature class using one or more of the features in another feature class as a "cookie cutter"

19

GIS Analysis: Intersect

• Computes a geometric intersection of the input features. Features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class

11

GIS Analysis: Union

• Computes a geometric union of the Input Features; all features will be written to the Output Feature Class with the attributes from the Input Features, which it overlaps

21

GIS Analysis: Buffers

• Creates buffer polygons around input features to a specified distance

GIS Analysis: Merge

• Combines multiple input datasets of the same data type into a single, new output dataset

23

• Aggregates features based on specified attributes
