Detailed Description

Header for TrackLoader,loading track files.

The TrackLoader class (UDT) is designed to load and analyse track files (*.NMEA and *.GPX, generated by MapFactor Navigator software). Individual parsers can get invoked in order to load different file formats.

Since: 0.0

Definition in file track_loader.bi.

Class Documentation

◆ TrP

class TrP

Data for a single track point.

UDT used to store the point data graped from the file. Undefined values get stored as NaN entries. The LONG values [XY]pix gets computed later for the current map zoom level.

Since: 0.0

Definition at line 32 of file track_loader.bi.

Class Members
DOUBLE	Tim	Date / Time.
float	Lat	Latitude.
float	Lon	Longitude.
float	Ele	Elevation [m].
float	Spd	Speed over ground [km/h].
float	Ang	Direction Angle.
LONG	Xpix	world X pixel for ploting
LONG	Ypix	world Y pixel for ploting

Typedef Documentation

Function Documentation

◆ latlon2zoom()

FUNCTION_AS_LONG latlon2zoom	(	BYVAL_AS_LONG	W,
		BYVAL_AS_LONG	H,
		BYVAL_AS_float	La0,
		BYVAL_AS_float	La1,
		BYVAL_AS_float	Lo0,
		BYVAL_AS_float	Lo1
	)

Evaluate the matching zoom level for BBox.

Parameters

W	Width of map widget
H	Height of map widget
La0	Minimum latitude
La1	Maximum latitude
Lo0	Minimum longitude
Lo1	Maximum longitude

Returns: Matching zoom level

This function evaluates the zoom level for the map in order to show a bounding box completely on the map.

Since: 0.0
