Can I create a kml file?

[KarlosAmigos]

Greetings,

In many of my applications I record GPS tracks. At present I log the lat/longs every second to a csv file in degrees, decimal minutes (D M.MM) format as we move. I would like to simultaneously save this data as a kml file that can be immediately opened in Google Earth at the end of our transect. Is there a way to do this in LabVIEW? ( I am using 2013).

I know that kml files want the coordinates in the format of  long, lat, in decimal degrees (D.DDD) and I have already written subVI's to do this.

Thanks,

Karl

The red statement is a little overenthusiastic. You don't show in that example how to add the actual coordinates into the file.

Thanks for the quick reply,

So I am essentially creating an xml file...kml is basically the same I take it.

Google Developers show a file as shown below to create a GPS path in kml form:

If I used the constants as shown by smsanthosh in his example to write all the headers and jibber jabber, then add my coordinates as I receive them to the file, then close file when the transect ends, this should work I think.

Two questions; what is the open file icon with the O N in it in this example? I am not familiar with that one and can't find it.

Just by giving the text file the extension kml, does this make it a kml file?

Thanks

Hi,

    Ya saving the text file to *.kml is enough. Once this menthod works for you post a reply to the comment....:)

Well, that was a lot easier than I thought it would be!

I will have to do more coding to append my streaming GPS data to the file, but the basics are all there. In my attached VI, I have just used a constant with some coordinates from the Grand Canyon and it worked perfectly.

Many Thanks

Karl
