Surface Geology of Australia, 1:2 500 000 scale, 2012 edition

DATA FORMAT: MAPINFO tables

DATASET DESCRIPTION:  Please read the dataset documentation in the metadata folder.

This MapInfo format data has been generated by converting an ESRI file geodatabase dataset.
Note that the ShearDisplacementLines (ie, Faults and Shears) attribute data table has been 
truncated (the MVTSENSE, DSPLCMNT, FLTSYS, and FLTSYSID fields have been removed) from the 
source data as the orginal source data table is too wide for a MapInfo format table.  
These truncated fields contained only NULL data.

Procedure for RGB colouring of thematic (geology polygon) data in MapInfo

=============================================================================

NOTE!!  This procedure requires users to add columns to a table. 
Versions of Mapinfo prior to version 8 may be unable to edit very large 
tables such as the 1:1M scale Geological Unit polygons. Smaller datasets 
(eg, 1:2.5M Geological Unit polygons) may be edited in Mapinfo versions prior 
to version 8.

=============================================================================

1.
Ensure that the Addcolor.mbx file is placed in a searchable MapInfo MBX directory.

2.
In MapInfo, use the File/Open menu to open the RGB.txt file.
Choose that the file delimiter is a comma.
The check-box for 'use first line for column titles' should be checked.
Click OK.
It will create a table with columns 'PLOTSYMBOL','R','G' and 'B'.
The other columns ('H','S','V') are not used in this process.

3.
Open the geology polygon data .TAB file. 
Using the Table/Maintenance/Table Structure menu, add 3 extra columns
to the table as 'integer' fields. Call them 'R','G', and 'B'.

4.
Using the Table/Update Column menu, populate the 3 new columns in the 
geology table from the values in the RGB.txt data. (You will have to
do this one by one for each column R, G, and B.)

  'table to update' is the geology polygon dataset.
  'column to update' is 'R'.
  Click 'Join'. This may generate an info dialogue box, click OK.
  Ensure that the top drop-box is 'PLOTSYMBOL' and the lower drop-box is 'PLOTSYMBOL'.
  Click OK.
  'calculate' should be set to 'Value'.
  'of:' should be 'R'.
  Click OK.

5.
Repeat the above procedure, using 'G' values and 'B' values for both.

6.
Run the 'addcolor.mbx' MapBasic program from the Tools/Run MapBasic Program menu.
Selected 'table to add color' is the geology polygon dataset.
'polygon outline' can be either checked or not, depending upon your
preference - when checked each polygon has a black outline.
'color scheme' should be set to 'RGB'.
RHS drop-boxes should automatically be 'R', 'G', and 'B' (top to bottom).
Click OK.

7.
The data will be automatically coloured according to the RGB values for
each PLOT_SYMB value in the geology polygon dataset.
