OzGIS Installation
==================
The software is supplied on floppy disks with most files compressed by
the PKZIP program (or you may have loaded it off a network host).
The files must all be first copied to the hard disk drive that you are going to
use.
Two directories are used:
\OZGIS holds all the system files
\OZDEMO contains example mapping files.
You must use the same disk drive as that holding \OZGIS for your own mapping
directories.
The installation procedure is as follows:
1. set up the \OZGIS directory
CD \
MKDIR OZGIS
2. copy all files from floppy disk to the \OZGIS directory
CD \OZGIS
COPY a:*.* (for each disk)
3. Run the installation procedure
INSTALL
4. Print the manual ( 100 pages) and the function key template
PRINT OZGIS.DOC
PRINT FNKEYS.DOC
The WOTSNEW.DOC file contains details of changes to the system.
5. Follow the procedure in the manual to set up your AUTOEXEC.BAT file and to
set up the .INI files for the type of video card (EGA/VGA) and monitor that
you are using.
6. Work through the manual following the examples to see how to use OzGIS.
OzGIS will run on an EGA board, but a 512K or 1MByte VGA board that gives 256
simultaneous colours is strongly recommended as it enables very fast
interactive choropleth mapping for maps of up to 240 zones. The VGA chipsets
that are supported are given in the manual e.g. Trident or Tseng Labs.
QUICK DEMO
==========
The manual will lead you through the configuration of your system and simple
examples. You can try the following, but if there are any problems GO TO THE
MANUAL.
You will have to do some configuration:
The start-up command file AUTOEXEC.BAT will have to be modified so the programs
can be accessed by changing the path statement to access /ozgis. e.g.
PATH C:\DOS;C:\PROGS;C:\OZGIS
The system file CONFIG.SYS has to have:
FILES=20
BUFFERS=20
Note that you will have to reboot your system before the changes to the DOS
files take effect.
The "DISPLAY =" parameter may have to be set in the file \OZGIS\INTERACT.INI if
you have an EGA:
DISPLAY = 10 (VGA with analog colour monitor)
or DISPLAY = 5 (EGA with RGB colour monitor)
or DISPLAY = 6 (EGA with enhanced colour display)
Now you can display maps using files supplied with the system:
type cd \ozdemo
ozgis
You should start by reading the manual, but there are several tutorials that
you can look at that describe the system, function keys etc.
The first example..............
choose the option "DISPLAY ZONES FOR AN ATTRIBUTE FILE".
give the attribute file name as OZ
give the geographic file name as OZ
You now have a default map with legend and distribution diagram. The legend
has the numbers of zones in each class on the left and the class value ranges
to the right of the coloured boxes.
Type F2 to hide the menu; then esc to show it again.
When you are using a 16 colour EGA or VGA you will find that the map does not
always change when you choose an option. This enables several parameters to be
set before going through the slow map drawing process. You have to specifically
ask for the changes to be applied.
Type F3 - this regenerates the display.
Now a second example............
Type F8 to return back to the top level menu.
Choose the option "DISPLAY GEOGRAPHIC FILES".
Choose the menu option "DISPLAY POLYGONS FROM A GEOGRAPHIC FILE"
Give the file name as "HAWDLGWB".
Accept the default polygon number and give the legend text as "Hawaii".
Accept the default (No) for drawing polygon boundaries.
The islands of Hawaii will be drawn.
Choose the option "OVERLAY LINE SEGMENTS FROM A GEOGRAPHIC FILE"
Give the file name "HAWDLGST"
Accept the default line number and give the legend text as "Rivers".
This example uses two files originally in DLG-3 optional format, off the USGS
CD-ROM. This is a simplified example; usually feature codes in these files are
used to subset the data e.g. to draw rivers and streams in different colours.
Finally -
Type F10 to exit from the program.
The manual will provide further information on configuring the system for VGA
boards and on how to use the system.

When you start using the system you should try the OzCensus program as it is a
subset of OzGIS and easier to learn to use.
