The dataset defines the extents and parameters for each of the GDA94 Landgate project grids. Project grids provide a Transverse Mercator (TM) based standard for the interchange of data for engineering, surveying and mapping projects. Within a project grid, the distance between two points on a plan will be the same as the ground distance to a defined tolerance of 20 parts per million (ppm). This makes the project grids ideal for engineering applications, facilitating the use of plane coordinate calculations for design and construction set out.
