Map File Format

In the text below the lines in the map file are marked with a dot.

Only those parameters which can be modified/created by the user are described, parameters which are used for special cases are not described.

The lines in green are optional

The Map File

The lines are in the order they are in the map file.

--------------------------------------------------------------------------------

Header and Version of File

OziExplorer Map Data File Version 2.1

--------------------------------------------------------------------------------

Title of Map - any text string

Brisbane Region

--------------------------------------------------------------------------------

Link to map image file

D:\OziMaps\regional\south.ozf2
Can be 1 of 2 things

1 TIFF scale factor - redundant, no longer used and has been replaced by line below
1 ,Map Code, - only used for special types of maps - Note - cannot be modified by the user but must be there.

--------------------------------------------------------------------------------

Datum settings

WGS 84,, 0.0000, 0.0000,WGS 84 - Note - for normal maps only the datum in the first field is used the rest of the parameters are for datum shifts and there is normally no need for these to be modified by the user.

--------------------------------------------------------------------------------

Reserved fields, the lines must be there

Reserved 1
Reserved 2

--------------------------------------------------------------------------------

Magnetic Variation entry - degrees,minutes

Magnetic Variation,,,E

--------------------------------------------------------------------------------

Map Projection

Map Projection,Lambert Conformal Conic,PolyCal,No,AutoCalOnly,No,BSBUseWPX,Yes
Parameters

Map Projection - must match the projection name used in OziExplorer
PolyCal - the next parameter is Yes if Polynomial calibration is used and No if not
AutoCalOnly - Yes if calibration cannot be adjusted by the user No if it can
BSBUseWPX - For BSB images only, Yes if the calibration equations contained in the BSB file are used.

--------------------------------------------------------------------------------

Calibration points, there are always 30
Only 9 points can be modified from within OziExplorer but OziExplorer will use the full 30 if they exist in the .map file.

The Moving Map section marker

Moving Map Parameters = MM? These follow if they exist
Use in Moving Map, if this parameter is set to No then the map will be excluded when looking for a new map to change to when using moving map mode. It does not affect other map find functions.

MM0,Yes
Number of Map border points (corner markers)
Only 4 points can be set graphically in OziExplorer but up to 100 points can be used when derived from other sources, such as importing BSB charts.

MMPNUM,4
The x, y pixel location of each border point, there must be an entry for each border point.
These are used by OziExplorer as the map loads to determine the map border points.

MMPXY,1,494,234
MMPXY,2,4076,238
MMPXY,3,4012,2855
MMPXY,4,549,2852
The lat, lon position of each border point, there must be an entry for each border point.
These values are used in the map find and moving map functions when looking for maps.
If these values are not there then the map will never be found.
If these values do not agree with the MMPXY points (after map calibration is applied) then map finding in moving map will not function correctly.
These values will be overwritten by the calculated value from the above x, y points every time the map is saved.

MMPLL,1, 147.999332, -23.998496
MMPLL,2, 154.000701, -23.999946
MMPLL,3, 154.001025, -28.001546
MMPLL,4, 147.998983, -28.001469
The scale of the image meters/pixel, its calculated in the left / right image direction.
It is calculated each time OziExplorer is run, the value in the file is used when searching for maps of "more detailed" scale.
