Specifications

Tracks which have been specified as
Alarm Zones
perform a special function when using
moving map mode.
Attaching Waypoint, Event or Route Files to the Map
When you attach these files you can only attach
1 of each
. The software will allow you to attach
more than 1 of each type but only the 1st of each type in the list will be processed. The attached files
are loaded automatically each time the map is opened.
However
if you have specified in the
configuration to
Keep Map Objects
(waypoints,events and routes) in the
Map Load Options
these
files will only be loaded if there are none of the specific object type in memory. This is done because
the 2 options conflict with each other, you cannot keep the specific object type (say waypoints) and
also load a waypoint file as well, as this would destroy the waypoints (objects) already in memory.
Even with the Keep Map Objects enabled when you load a new map, the ability to attach waypoints
etc to a map is still very useful the 1st time you load (or autoload) a map for each session of
OziExplorer.
Use Polynomial Calibration for map
To use this option you must have 7 or more calibration points specified.
If this option is ticked OziExplorer will use 2nd order polynomial calculations when calibrating the
map. This allows maps to be calibrated even if they are not truly square (linear). This is useful for
calibrating maps where the true map projection is not known.
Limitations
- Using a polynomial calibration on a truly linear map can cause unpredictable results.
Moving Map Options
Include in Moving Map
- Once you have ticked this option this map will be checked when your
position moves off the existing map and the software is attempting to locate the next map to
automatically load. There are good reasons for not including certain maps in the moving map
process. Example
- if you included the world map and there were no other "better" maps for the
software to select it would be loaded. You may also have other maps for experimenting which you
may not want automatically loaded. However if a map not ticked for automatic inclusion in the
moving map process is loaded manually the software
WILL
attempt to find another map.
BSB Calibration
Many BSB charts have a set of calibration equations provided by the manufacturer of the BSB chart.
There are some charts where these equations have errors in them and calculate an incorrect
calibration. This option allows the calibration of the manufacturer to be replaced by a calibration
calculated by OziExplorer. If the
selection is disabled
then you do not have a BSB chart loaded or
the BSB chart loaded does not have the calibration equations provided.
Image Formats Supported
There are 3 things required in a good raster image format for mapping use.
1. High compression to give small file sizes.
2. The ability for the image to be paged from disk to reduce the amount of memory required.
3.
Fast loading of the image or image pages.
