These tracks are intended to be visualised on maps, plotted as distance/altitude profiles, have statistics derived from them, etc.
The 'base' trackfield CCK field knows about latitude, longitude, altitude and distance.
Due to the flexibility of the system, the distance/altitude pairs can be provided without the need for latitude/longitude.
Unpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules.
Here are some key features of "Trackfield":
· trackfield - the 'core' field with data storage rules. Standalone it cannot accept input data nor display it.
· trackfield_crs - gives trackfield the ability to accept text in CRS (Garmin course) format.
· trackfield_csv - gives trackfield the ability to accept text in CSV format.
· trackfield_kml - gives trackfield the ability to accept text in KML format.
· trackfield_gpx - gives trackfield the ability to accept text in GPX format.
· trackfield_file - instead of the input field, data for other input handlers (CSV, KML, GPX, etc.) can be read from a file attached to the node.
· trackfield_graph - creates graphs (eg. distance/altitude) from a trackfield. Has the ability to normalise/compare more than one field.
· trackfield_map - uses the gmap module to display a trackfield.
· trackfield_stats - create any number of fields with statistics derived from trackfield data. Distance, gradient (where altitude is available), max speed (where time is available), etc, etc. Users may input statistics manually for nodes they wish to create and store these details in, but for which no source track data is available.
· trackfield_kml_out - include trackfield in KML output where latitude/longitude are available.
