Warwick-Tweed Heads Geoscience Data Package (2001 Revised 2012)

Abstract

GIS formatted datasets include geology (including prelim. QLD data and 1:25 000 mineral occurrence maps); historic titles; mineral occurrences; heavy mineral sand placers; petrological data; and exploration geochemistry. Geophysical imagery (TMI, DTM, Ternary Radiometric and Landsat) has also been provided in this revision Apart from the geophysical images, these datasets have not been updated during the 2012 upgrade of this Data Package. All other datasets remain current to the original date of publication (Oct. 2001). This Data Package does not contain the 2014 map or the 2015 metallogenic study. 

Comments

The GIS data contained in this Data Package was originally compiled for earlier (now unsupported) versions of ESRI & MapInfo GIS software. As a result, some of the customisation originally incorporated into these packages may not completely function in more recent ESRI & MapInfo GIS software. Also note that the GIS data in this package was compiled in 2001 using the now-superseded AGD66 datum but has been reprojected to the current (GDA94) datum as part of the 2012 October upgrade. This update includes: Reprojected GIS data (Transformed from AGD66 datum) to GDA_1994_MGA_Zone_56. Creation of MXD and PMF files for improved ESRI functionality. Updated workspaces for enhanced performance in more recent versions of Mapinfo. Creation of KMZ files for operability within Google Earth. Updated geophysical images Total Magnetic Intensity (TMI, 50m, 1VD RTP), Digital Elevation Model, Composite KUTh Radiometric, Landsat Image.
