Not sure how your original tracks and data were recorded, but if they are as GPX files then the key might be to leave them as this rather than trying to turn them into anything else. If not, then perhaps export as GPX. GPX does a good job of storing tracks in particular. What's important about a GPX track is that it's a record of a set of readings of point ...

This site originally written by Dale DePriest and based on NMEA version 3.01 says that field is "Track angle in degrees True." I would interpret it as an azimuth relative to True (Geodetic) North. The missing checksum means that the data can't be verified. There's could be an error in the sentence, but you can't verify the data that's there. In reality, I ...

I had a brief stint with GPS/GIS tech support a while ago so I am a little rusty. I do remember the Windows PocketPC's com ports getting hung up. The problem was usually 1 of 3 things. 1. a compatibility issue with a combo of Terrasync, the OS on the GeoExplorer, GPS Pathfinder Office (data transfer utility) or Microsoft's Activesync. 2. Terrasync was ...

I'm aware that this is quite an old question, but as this post is one of the top search results for this topic, I thought I'd post my workflow for producing polyline heat maps in ArcGIS, as there is currently no answer for ArcGIS in this post. This technique requires the polylines to be coincident, i.e. exactly overlaying each other. If your data does not ...

If I'm understanding correctly, there should be no correction applied since there's no base station to calculate it from. Since the GPS knows the approximate location, it will know whether any correction signal it receives is applicable or not. ...so even though GPS users there can receive WAAS, the signal has not been corrected and thus would not ...

Tom and Steve are correct. You could you a consumer GPS or your phone to do this. I have done this testing, and wrote a paper about this. You can see the paper here: http://bit.ly/11nKC5Y to see my results. You will want to check the results of anything you GPS. To tackle your comment about making each segment its own record, you can do this with GIS ...

Does this Help? Not sure if the sentences are device specific, and it's a bit dated. But this could be a good place to start. http://www8.garmin.com/support/pdf/NMEA_0183.pdf I Found The link above in a post on the Garmin Forum here.

There is a Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz, it has position accuracy of <3 meter, velocity accuracy of 0.1 meter per second and cost around 40$. For a working model with Raspberry Pi, here is a tutorial.

I use GPX format to transfer data from and to Basecamp. The older version I use can also export csv, and import kml and csv. But since I use GPX for export to and from the GPS unit too, I prefer that format for all exchange. You can however not use the Garmin based .img files inside QGIS.

I would log in to Samsungs page and see if it shows the last position thereunder find my phone. Can also have the option to wipe it or ring it.
