Abstract
ADMAP is a Gridmerged compilation of over 700 individual survey TMI grids, with a cell size of approximately 80 m (in fact it is 0.000833333 degrees). The first preliminary grid at this resolution with data type IEEE4ByteReal is called "aust_18122007_008333.ers"

Lineage
The Australian Digital Magnetic Anomaly Map (ADMAP)results from a completely new compilation of Total Magnetic Intensity (TMI) grid data. which has been produced using a new method of matching the individual survey grids and the use of independent data to help constrain long wavelengths. 700 individual grids have been matched and merged into these composite grids, with the resolution of each grid optimal for the specifications of the source survey line data. Since the Third Edition (Milligan and Tarlowski, 1999), data from many new surveys have been added, acquired mainly by the State and Territory geological surveys. It is estimated that 19 million line-kilometres of survey data were acquired to produce the grid data, 10 million line-kilometres more than for the Third Edition.
