Use the Track Control Property buttons to load and save the tracks and set the properties for each of
the tracks. By saving the track the properties are saved with the track. Each track can be displayed
independently.
Manually Creating Tracks
Tracks can be created directly onto the map and then saved to file and/or sent to the GPS.
To manually create a Track.
When manually creating a track you are always working with track number 1.
Press down the
Manually Create Track Point
Button which is located on the button bar
Move the mouse pointer to a selected location on the map and press the left mouse button -
a track
point will be added to the map joined to the last previous point which was created. You can continue
adding track points until you have reached the number specified for your GPS.
CAUTION :
Eagle and Lowrance units do not store the absolute position of each track point but
store the x and y distance in meters from the previous point. The variable in which they store these
distances is an integer (2 bytes), this limits the distance (x or y) to 32,535 meters or 32.5 kilometers.
What does this mean, it means the distance between any 2 track points in either the x or y direction
cannot be greater than 32.5 kilometers (give or take), keep this in mind when manually creating track
points as OziExplorer does not as yet warn you when you have exceeded this value. If you upload
values greater than the maximum the values wrap and the track can go anywhere (usually in the
opposite direction that you intended).
Special keys which can be used when Creating Track Features
For efficient creating of map features the use of these key combinations is essential, I suggest you
print them out or write them down so they are easily seen.
Holding the
Alt key
down when creating a new track point will automatically start a new track
section.
Holding the
Shift key
down when creating a new track point will "snap" onto the closest track point
to the point where you clicked.
Holding the
Shift & Ctrl keys
down together when creating a new track point will "snap" onto the
closest track line to the point where you clicked.
Holding the
Shift & Alt keys
down together will create a new track section and "snap" to the nearest
track point.
Holding the
Shift & Ctrl & Alt keys
down together ( need good finger control) will create a new
track section and "snap" to the nearest track line.
These options are also available on the right click menu of "Active" track points.
