    Dashware nerds: How to make a gauge for 3D GPS data?

    It would be cool to have a Dashware gauge to trace the GPS rocket flight on a 3D map like Google Earth:

    However, the Dashware map gauges are 2D only, accepting latitude and longitude and converting to X and Y map coordinates. No elevation or Z coordinate. So, the above looks like this:

    Is there a way to trick Dashware? I found this in the FAQ, using an image component, but it is still 2D:

    It is possible to do, but I don't know a "quick and easy" method.

    If you can convert the data you collect from your GPS device into "KML" data, you can use the instructions here:

    https://support.google.com/mymaps/answer/3024836?hl=en

    to put your 3D data into google earth where you can view it from any angle you'd like.
    In the attached picture, I used this approach to take *calculated* data from OpenRocket and overlay it onto one
    of my clubs actual rocket launch fields.

    Yeah, I can get kml into Google Earth no problem. That is my first picture above. However, I want the GPS track to animate, like the Dashware 2D map gauges that trace the route over time, synced to my on-board video and altimeter data.

    I played around with the "tour" function in Google Earth, but that isn't what I need.

    You should be able to use some trig to modify your x, y and z coordinates to display in any required orientation. Then you could use this technique as long as you can get a screen shot from google earth at the same orientation.

    Did you get this working? If you want to attach your log file I’ll give it a shot when I can.

    Nope. I never did anything more with this. You want my GPS track (kml)?

    I don’t think KML has time encoding on it (at least the stuff I’ve looked at before didnt). Your original logs would be better.

    I managed to do this using NMEA Monitor to replay NMEA files at 1 sample per second.
    I had to use 2 programs to get the data to Google Earth. In GE I used the Movie Maker option to record the result as it played

    Video will be here once upload is complete:
    https://youtu.be/fS7y4_uARrI
    Note that you need to wait a bit for the action to start.

    The Following is an overview of the configuration:
    NMEA Monitor read in NMEA log file and output to com port 23 port
    Virtual Serial Port Driver redirects com port 23 port to com port 24
    GPS Gate Splitter read in com port 24 and output using its built in adapter to Google Earth

    NMEA Monitor is available here for free http://4river.a.la9.jp/gps/
    Virtual Serial Port Driver is available here for free 14 day trial https://www.eltima.com/vspd-comparison-chart.html
    I've not tried it but this this completely free alternative may work instead of VSPD http://com0com.sourceforge.net/
    GPS Gate Splitter is available here (don't get confused with their server product) http://gpsgate.com/download

    Edit - ok failed to upload overnight. For some reason GE produced a nearly 1GB movie. The worst bit is that the reason I thought it was successful is that it was taking for ever to play back on my old laptop. In fact what GE did was to time compress the whole thing back to a 6 second movie undoing all the work I went to getting it to display at the correct speed
    So if you want to do it this way you’ll need to do some sort of screen capture as well.

    No joy on the youtube video.
