Ozi Explorer .plt format

Radio Mobile uses the PLT-format from OZI Explorer. This chapter discribes the format. Also a example in combination with line objects is displayed.

Track File (.plt)

This information is copied from: http://www.oziphototool.com/fileformats.html.

track file (.plt)
Line 1 : File type and version information
Line 2
: Geodetic Datum used for the Lat/Lon positions for each trackpoint
Line 3
: "Altitude is in feet" - just a reminder that the altitude is always stored in feet
Line 4
: Reserved for future use
Line 5
: multiple fields as below

Field 1 : always zero (0)
Field 2 : width of track plot line on screen - 1 or 2 are usually the best
Field 3 : track color (RGB)
Field 4 : track description (no commas allowed)
Field 5 : track skip value - reduces number of track points plotted, usually set to 1
Field 6 : track type - 0 = normal , 10 = closed polygon , 20 = Alarm Zone
Field 7 : track fill style - 0 =bsSolid; 1 =bsClear; 2 =bsBdiagonal; 3 =bsFdiagonal;
4 =bsCross; 5 =bsDiagCross; 6 =bsHorizontal; 7 =bsVertical;
Field 8 : track fill color (RGB)

Line 6 : Number of track points in the track, not used, the number of points is determined when reading the points file

Trackpoint data

  • One line per trackpoint
  • each field separated by a comma
  • non essential fields need not be entered but comma separators must still be used (example ,,)
    defaults will be used for empty fields

Field 1 : Latitude - decimal degrees.
Field 2 : Longitude - decimal degrees.
Field 3 : Code - 0 if normal, 1 if break in track line
Field 4 : Altitude in feet (-777 if not valid)
Field 5 : Date - see Date Format below, if blank a preset date will be used
Field 6 : Date as a string
Field 7 : Time as a string

Note that OziExplorer reads the Date/Time from field 5, the date and time in fields 6 & 7 are ignored.
