The OzGIS system is designed for ANALYSIS of spatial attribute data.
A common application is the display of Census data.
Visual inspection of choropleth maps is the intuitive way to interpret the
spatial features of data. An analyst needs to be able to rapidly display and
manipulate maps to aid his understanding. OzGIS was designed to enable maps
to be changed within seconds so the analyst does not lose his train of
thought.
OzGIS enables the analyst not just to display a map, but to generate the
map that best shows the features of the attribute data. A hardcopy map can be
generated as the final operation as a record or for dissemination.
OzGIS aims to accept basic data files and to provide most of the facilities
required for the analysis and display of attribute data as choropleth maps.
The analyst has to be able to rapidly use the facilities, so OzGIS provides
an interactive user interface. The user interacts via menus and is aided by
on-line assistance.
The system consists of several modules:
OzEnter - for entry of data files into the system.
OzData - preparation of data for mapping
OzGIS - interactive display and analysis
OzCensus - Display and analysis of Census type data (subset of OzGIS)
OzGISco - maths coprocessor version of OzGIS
OzMap - output of saved displays on plotters and printers and to files
OzZone - formation of zones / polygons structure from line segments
OzProj - map projections
OzTerr - interactive territory definition
Future releases may include:
OzCatch - allocation of zones to site catchments
Easy to use systems are necessarily trivial systems, and the enormous number
of options within OzGIS means that it takes some time to understand
everything.
However, maps can be produced quite simply by using only a small number of
options and by using the system defaults. It is suggested that the OzCensus
program be used at first while becoming familiar with the system.
READ the manual!!!!!!!!!!!!!!
The manual is on file \OZGIS\OZGIS.DOC. It is over 100 pages long so find
someone with a laser printer.
While the manual is no masterpiece, the information you require should be in it
somewhere.
The manual tries to lead readers through the main options first and for the
most common applications first. Working through the manual and generating
the maps as explained will soon provide the knowledge to enable the rest of
the system to be used.
You should also print the file \OZGIS\FNKEYS.DOC which is a function key
template that you can put across the top of your keyboard.
You should have seen the starting file \OZGIS\READ.ME. If someone else
configured the system you should have a quick look at it.
The system comes configured for an EGA card, so you probably have to set it up
for your hardware, but you can try out the system as it is.
You should try out the OzCensus program first - its designed to be an
introduction i.e.
cd \ozdemo
ozcensus
Select the option to display a new map and give file names as "OZ".
Also look at the tutorial files (they are usually bits of the manual).
