Viewranger mapping app

Today, I’m going to be using Viewranger route tracking app for Android.

Due to the limitations of Googlemaps, I’m going to find something which will store and record the routes that I’ve taken, does the maths, and plot the graph for me.

Maps has a limit for the online version. I can only add a certain amount of content before it tells me I’ve exceeded the given number of separate additions to the one map.

So, I’m trying something new, and tonight’s map will be done with Viewranger, (hopefully).

 

 

Creating a KMZ Polyline using Google Earth Pro

Brief: To download a GPS Track from a Garmin E-Trex GPS unit and create a Google Earth Polyline/Encoded Polyline KMZ.

Equipment:
Garmin EtreX GPS unit.
Serial port adapter.
Google Earth Pro.

  • Download Google Earth Pro – 7 Day free trial
  • Install/boot

  • TOOLS/GPS – Select your unit; In my case the GPS GARMIN.

  • IMPORT options. In my case I’m only interested in the polyline or TRACK information. You have options to import each placemark, also to annul altitude readings etc.

  • Plug in the GPS and turn it on.

  • A message appears – Importing data from COM1. When you’re done, a message appears 207 Active logs imported.

  • TRACK is displayed in the Temporary Places folder.

  • In the top left corner there’s a little marker with a CLOCK alongside.
    In the CLOCK, select the timerange you’re interested in presenting data from. In my case 1st Sept to 21st Sept.

  • Once the CLOCK is set the software will begin displaying the TRACK that lies within that timeframe.

  • This next part is manual. Select TRACK parts, (google calls them ACTIVE LOGS), which are not part of your timeframe and DELETE them.

  • When you’ve pared off the bogus ACTIVE LOG points and you’re happy with your track, you’re ready to save: TRACK/SAVE AS/KMZ.

IF YOU DON’T DELETE bogus active logs the software becomes confused when you try to do any kind of visualisation. So be sure to do that smartening up yourself.

Welcome to my world..
This is now your very own track you can open in any Google Earth pro, Google Maps or otherwise.
You can view it save it to your places and e-mail it to your friends.

Just in case you’re thinking of doing a blog. I recommend for foriegn hire car; bigger is better.
I had a Mustang in the US. An S-series in Poland and this slightly shady Toyota here.

Towns are easier to find your way round if your car does the talking for you.
