Geological Mapping data

Digital Geological Mapping Data (current to July 2008)

Digital geological mapping data include vector coverage of 1:100 000, 1:500 000, 1:1 000 000 and 1:2 500 000 scale geological maps, and raster colour scans of 1:250 000 scale geological maps.

The availability of these data can be seen on the Queensland Digital Geological Mapping Data (PDF, 200 kB) map, that shows 1:100 000 scale vector map coverage and the GIS Data Packages coverage; and the Regional Maps (PDF, 186 kB) map that shows 1:500 000, 1:1 000 000, and 1:2 500 000 vector map coverage.

Digital vector data

The vector data discussed above represent the current status of the available data as contained on the 2 x DVD product 'Queensland Geological Mapping (polygonised vector) Data - Regional & 1:100 000 Sheet areas July 2008'.

This DVD product supersedes the 'Queensland Geoldata- Zone 54N to Zone 56S and Regional' product which was supplied as a collection of seven compact discs.

In summary this edition provides new geology data on 14 1:100 000 geological map sheet areas, updates 94 map areas, and includes data correction to 1 regional map sheet area.

Drummond Basin: New data is available for the Milray, Yarrowmere, Bowie, Mount Tutah, Bulliwallah, Epping Forest, Albro, Surbiton, Zig Zag, Bogantungan, Anakie, and Nandowrie 1:100 000 sheet areas. Updated data is available for Pajingo, Harvest Home, Natal Downs, Scartwater, Gunjulla, Wyena, Frankfield, Kilcummin and Monteagle 1:100 000 sheet areas.

Central Queensland: Main updates are to Eidsvold, now complete sheet previously only 10 minutes wide; Mundubbera, now complete sheet previously only 10 minutes wide; Monto, edge match to Eidsvold; Rawbelle, edge match to Eidsvold; Auburn, edge match to Mundubbera. Minor changes include new keys to reflect Queesland-wide codes and updated weathering (except Gladstone and Mackay) on the Mirani, Mackay, Nebo, Carmila, Bombandy, Connors Range, St Lawrence, Windeyers Hill, Mount Bluffkin, Marlborough, Cooroorah, Strathconan, Comet, Dingo, Mount Morgan, Gladstone, Banana, Biloela, Theodore, Scoria, and Cracow 1:100 000 sheet areas. Weathering updates have been made to the Bungaban, Barakula, Calliope, Duaringa, Guluguba, Ridgelands, Rockhampton, and Rookwood 1:100 000 sheet areas.

North Queensland: Geology updates and weathering updates (W) include the
Atherton (W), Bartle Frere, Belfield (W), Bullock Creek (W), Burges (W), Cardwell, Cashmere (W), Charters Towers (W), Chillagoe (W), Chudleigh Park (W), Clarke River (W), Conjuboy (W), Croydon (W), Dotswood (W), Einasleigh, Esmeralda (W), Etheldale, Ewan (W), Forest Home (W), Forsayth, Georgetown, Gilbert River (W), Gilberton (W), Hampstead (W), Hillgrove (W), Homestead (W), Ingham, Innisfail, Kangaroo Hills (W), Kirrama (W), Lolworth, Lyndbrook (W), Lyndhurst, Maryvale (W), Mingela, Mount Norman (W), Mount Surprise (W), Mungana (W), North Head (W), Pelham, Pentland, Prospect, Ravenshoe (W), Ravenswood (W), Rollingstone (W), St Ronans (W), Townsville, Tully, Valley Of Lagoons (W), Wandovale (W), and White Mountains 1:100 000 sheet areas.

In order to satisfy client demand, the department now supplies the fully attributed geological line and polygon data in MapInfo as well as Arc/Info shape and export files, in geographic co-ordinates based on the GDA94 datum. Note that Map Sheet extents still conform to the defined AGD66 map sheet extent.

Additionally as a visualisation enhancement, the geological unit polygons on this DVD release are depicted using RGB colours approximating (on a PC monitor) those defined on the Australian Standard Colour Scheme for geological maps. The colour values have been chosen based on the Age and Rock Unit Type of each polygon key held in the Geological Resources Database. 

For this purpose, the 'ESRI Shape' folders contain a 'sheet no'_r.lyr which can be viewed in ArcMap; and for viewing the colouring in MapInfo, use the 'sheet_no'_r_rgb.tab files in the MapInfo folders. Please note that layer and .tab files created using the colours will not give output exactly matching the colouring on geological maps.

Approximately 135 PDF files created from postscripts of recently published 1:100 000 maps or scans of some regional sheets are included.

Attached to each of the map tiles is a Metadata file in .xml and .html formats. Metadata statements provided with datasets that remain unchanged from their previous releases will contain content relevant to the time of that release, eg Agency name, contact details.

Due to the volume of spatial information now contained in these data, they are supplied on DVD. The data are presented in a two DVD jewel case with the 1:100 000 detailed geological data on one DVD and regional map datasets on the other. The set is available from the Department for the 'cost of provision' (view pricing).

Raster data (images) of 1:250 000 geological map sheets

Published 1:250 000 Geology maps were scanned, in most cases, in four sections with one or two scans covering the map references. Derived JPEG images of the map faces were geo-referenced to AGD66 lat/long co-ordinates. These scans are contained on the DVD product Queensland Geological Mapping raster data images of 1:250 000 geological map sheets.

1:250 000 geological map sheets can be seen on either of the vector data maps linked on this page.

Vector data in GIS Data Sets on CD

Many of the map areas are also included in GIS sets along with additional data layers such as tectonic elements, solid geology, observations, mineral occurrences and geophysical images. However, note that unless otherwise indicated, the geology layers in the GIS packages have not been updated since the packages were assembled. Therefore the map tiles in the Digital Geological Mapping Data product may contain more recent updates due to new work and error corrections.
