Map Grid of Australia (MGA) Graticule - 1 km interval

dataset: GRAT_MGA_1K
This dataset is designed to be used as a "graticule layer", allowing a graticule to be drawn on maps when using software packages that don't support their generation in other ways. It consists of lines spaced at 1km intervals, running north-south (attributed with Easting) and east-west (attributed with Northing). It is applicable for use where an MGA graticule is required. Can be projected to provide AMG graticules over non-MGA data (eg Geographic or AMG). This dataset forms part of a series of graticule layers, one for each common projection.

Statement
Dataset Source: Created from first principles using explicit locations of graticules. Dataset Originality: Primary 
Description
Collection Method: Created from first principles. 
Description
Lines were created using Arcinfo Generate with a spacing of 1km. Verticies were then added to these lines at a 1000m intervals (using ArcInfo DensifyArc), thereby allowing the lines to 'bend' somewhat when reprojected. Attributes for the lines were imported from a look up table built in excel. This process was undertaken for both zone 54 and zone 55, and the two datasets appended alone the zonal boundary. Therefore the one dataset will provide both coordinates for either zone, depending on the location.
