OzGIS MAP TYPES
===============
Several types of maps and diagrams can be displayed by the OzGIS program.
The type required has to be selected from the main OzGIS menu.
Attribute maps
--------------
There are one or two streams of attribute processing for the types of
maps available for zone, line and site attribute data:
- zones map e.g. display of Census data
- lines map e.g. display of traffic densities on roads
- sites map e.g. display on number of childred at schools
- two zone streams i.e. bivariate maps
- zones and lines
- zones and sites
Geographic (GIS) maps
---------------------
Maps can be displayed that show geographic data without attribute data i.e.
polygons, lines, names at points and symbols at points.
Where the data are preclassified, feature codes can be used to subset the files
for display.
Diagrams
--------
Distributions, sorted values and quantisation results can be displayed as full
screen diagrams for one or two attribute files. Scatter diagrams can be
displayed for two files.
You can change attributes and quantisation in the usual ways (and type F3 to
show the results).
Saved displays
--------------
Maps can be saved on files and recalled later.
Presentations
-------------
This option enables a set of saved display files to be defined for
demonstrations.
An Ascii file is set up that gives the names of the saved display files and
menu lines that are associated with them.
