- 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).
