Does anyone here draw tracks with desktop detail & then follow onmobile devices?

are anywhere near a roadway.


Thanks greatly to Poutnik and Hans-Georg, and others, the answer to the
question is a resounding yes!

While there are many ways to accomplish any task, some of which use only
a single mobile device and a single map freeware app (Locus Map Free).

However, since I needed a large screen with great detail (trees, rocks,
clearings, etc.) with simultaneous topography (isocline lines), the
simple combination of a desktop solution coupled with the mobile device
worked best for me.

The simple solution was:
a) Install Locus Maps Free on Android
b) Download free USGS topographic maps of interest into Locus Maps Free
c) Create the desired path on Locus Maps Free
d) Follow that path on the ground with point-to-point audible/visible
"Guidance" in Locus Maps Free (without cellular signal)

The far better (more precise) solution was:
a) Simultaneous topography coupled with satellite imagery in Google Earth
b) Create a path in Google Earth & output as KML/KMZ (GPX is not allowed)
c) Optionally, convert the KML to GPX with BabelGPS freeware
d) Slide (or email) the resulting KML or KMZ or GPX files to Android
e) Install Locus Maps Free on Android
f) Download free USGS topographic maps of interest into Locus Maps Free
g) Load the newly created KML/KMZ/GPX files into Locus Maps Free
h) Follow that path on the ground with point-to-point audible/visible
"Guidance" in Locus Maps Free (without cellular signal)

Here is a recap of just some of the steps involved in the solution:
TO CREATE PATHS AND CONVERT TO ROUTES FOR OFFTRAIL GPS GUIDANCE:
1. Draw the desired path in Google Earth (using topo & satellite maps):
http://johnsantic.com/maps/trail_map_4.html

2. Right click on the path in the "Places" sidebar then save as
either KML & KMZ files.
http://cycleseven.org/creating-a-gps...n-google-earth

3. Just in case I needed it, I converted the KML file to GPX
using GPSBabel freewa
http://www.gpsbabel.org/

4. Copy those files over to your mobile device:
Note: In my case, since the mobile device mounts as a USB device
with MTP, I simply plugged in the mobile device to my desktop, which
automatically mounted the mobile device with two mount points
"Phone" & "Card".

Using the desktop file manager, I slid the KML/KMZ/GPX files over to:
SAMSUNG Android SGH T999/Phone/Download/test1_kml.kml
SAMSUNG Android SGH T999/Phone/Download/test1_kmz.kmz
SAMSUNG Android SGH T999/Phone/Download/test1_gpx.gpx

5. Start Locus Maps Free & load in those files:
[Locus Maps Free]Menu More Import data
[LOCAL FILE]/STORAGE/EMULATED/0/DOWNLOAD/test1_kml.kml
[LOCAL FILE]/STORAGE/EMULATED/0/DOWNLOAD/test1_kmz.kmz
[LOCAL FILE]/STORAGE/EMULATED/0/DOWNLOAD/test1_gpx.gpx

Note: All three worked just fine.

TO VIEW GPS TRACKS IN GOOGLE EARTH (TERRAIN/TOPO):
1. To view your KML file in Google Earth satellite view:
Start Google Earth:
GoogleEarth: File Open MyTrack.kml
http://i.imgur.com/PdNIe7T.jpg

You can tilt the view so that you can better see heights:

2. To better see the elevation lines, obtain USA USGS topographic maps:
Point your web browser to http://www.earthpoint.us/TopoMap.aspx
Press the "View on Google Earth" button
This will Download USGS topo maps named "EarthPointTopoMap_012701.kml"

3. Load the USA USGS topographic map into Google Earth:
GoogleEarth: File Open EarthPointTopoMap_012701.kml
GoogleEarth: View Sidebar

4. Select the Earth Point Topo Map USGS Quandrangles:
GoogleEarth: Places Earth Point Topo Map USGS Quadrangles

5. Load your KML track which will now topographically show on GE:
GoogleEarth: File Open MyTrack.kml
You will see your tracks on a topographic map.

You can tilt this topo map, but I always have issues with tilt.

6. If you loaded a KMZ file, you can save as KML for portability:
GoogleEarth: File Open MyTrack.kmz
GoogleEarth: File Save Save Place As MyTrack.kml

7. To return to satellite view, uncheck what you checked above:
GoogleEarth: View Sidebar
GoogleEarth: Places Earth Point Topo Map USGS Quadrangles

TO VIEW GPS TRACKS IN A GOOGLE MAPS BROWSER (TERRAIN/TOPO):
a. Go to https://www.google.com/mymaps on any web browser.
b. Click on "Create a new map" (mandatory google signin).
c. If necessary, register a google account name (it has to be done).
d. Once signed in, you will see "Untitled map" & "Untitled layer"
at top left.
e. Press the "Import" link below "Untitled layer" at top left.
f. Drag or select the desired CSV, XLSX, KML, KMZ or GPX track file.
g. Your hiking track will show up in the browser in the "Base" Google Map.

h. Change the Base map to "Terrain" in the bottom of the top-left box.
i. That same track will show up in the browser in the "Terrain"
Google Map.

Unfortunately when you zoom in to about a half mile, terrain
goes blurry.
k. To export the track as a KML, locate the Export to KML button.
j. To share this track with others, click on "Share" in the top left box.
