So how should this be done? HTML5+JavaScript app etc. or just something that dumps the data to a file and then one just uses something to visualize it?
Use csv (comma separated value) for both input and output files. Visualize using http://www.gpsvisualizer.com/
I propose the following csv format:
Input files: latitude, longitude, maxCTE, maxPassDist Here, maxCTE is the maximum cross-track error and maxPassDist is the radius of the waypoint. Latitude and longitude are the waypoints.
Output files: YYYYMMDDHHMMSS, latitude, longitude, CTEratio Here, CTEratio = (cross-track error) / (maxCTE). The higher the ratio, the more off course we are. Latitude and longitude are the points that we have passed through and the capital letters signify the date.
I have attached an explanation of the cross-track error below (marked as XTE). Source: http://www.sailtrain.co.uk/gps/images/distance_xte.gif
And all of the units are in degrees and meters! Time is always UTC.
Use e.g. http://www.gpsvisualizer.com/
I'd like an ordinary csv format to be used in GPS output.
