General Discussion / Re: GPS track animation
June 18, 2012, 03:37:02 PM
Dave,

Thanks for the reply - Yes, I had thought about Google.
Again, living in a rural area - the coverage resolution is very poor.
I need to get down to  field level detail - hence the wish to use my aerial photos (1 metre/pixel res).
As I mentioned, Topofusion develops a great track animation and it seems that I have to run that without a background photo. with the video of the dog working at its side. The aerial photos associated with topofusion  (being similar to Google for my area) have not the resolution either.

From the lack of responses - I presume that I am out of luck.
Thanks to all that may have cast a thought to the request.

General Discussion / GPS track animation
June 16, 2012, 06:23:40 PM
Hi to all,

Back ground info:
I track with a German Shepherd dog for sport - the tracks being from half an hour to 12 hours old over a distance from less than 50 metres to 3 kms  over or through varied terrain.
When the tracks are laid - they are done so with a GPS unit being carried by the tracklayer.
When the dog follows afterwards - the GPS is then carried by the dog.
Since the track is not visible to the human eye (hence dog using nose) - the two tracks may then be compared at a later time for an indication of accuracy of the dog.
I intend to create a picture in picture presentation - where the track is animated whilst viewing a video of the dog running the track. This aids in training and watching the canine behaviour traits as it tracks.

The video part is no problem.
The GPS track animation is!
Topofusion will give a good track presentation BUT using very poor quality aerial photos (for my area - PEI, Canada). I am able to run "Topo" without a background photo but would really like to have a program that allows me to place my 1 metre res. MRSIDs behind the track.
Any ideas? 

Grateful for any response.

Apologies.

Who's Sheldon?
- The correct person responded! :)

After about 5 minutes of fussing with my 60CSX I can't figure out how to show more than one track at a time.

Following Boyd's clarification, yes, I am now able to place as many tracks as I wish onto the screen at the same time. When the option "Show on map" is indicated - the unit is not showing the track(s). They will only appear once that option is pressed and then "Do not show on map " is indicated!

But weren't you loading the same files to both GPSrs?

The initial .shp file, converted to a .gpx file is uploaded to both units, ie. the same file goes to both units. Just that one unit treats it in one manner and the other treats it in different way when stored on the chip. The CSx holds it as one track, the 62s as a multiple number of separate tracks.

I don't have a 62s...........

But if you choose the option to show the track on the map, exit the track manager, then go to the main map screen you should see all the tracks you have enabled.


Boyd,
How's this for inverted logic!
I was under the impression that when :Show on map" was indicating - the track would be showing on the map and if that option was pressed to show "Hide on map" it resulted in the track being hidden! - so that has been cleared as I have now all the tracks I want present on the screen. Thank you for that.

On my 62s the "Show on Map" button is third from the top.  Sequence after you've selected a track is:
View Map
Elevation Plot
Show on map (or Hide on map)
Set Color
Change Name
Copy Reversed
Delete
Archive


Sheldon - presume that you have read the above!

I will go back to DNR and make sure the original .shp file is being loaded down as a .gpx to the two units in the same manner, since as initially stated - one is loading the .gpx and then showing that file as a unified image. Whereas, the 62s is receiving the file and then showing the components as unique individual tracks (64 of them). Meaning if I want to have them showing on the screen, I have to set each one to show!
Still searching for the origin of the difference between the two units.
Bear with me and do appreciate your time on this matter.

It will work on the 62s also I just cluttered up mine with about 4 different tracks simultaneously.  Made them different colors so I was sure I was looking at more than one.  Select each track that applies and select "Show on Map"..

Hi Seldom,

Maybe  Ia m being totally dumb - but how did you get different tracks to show together on the screen?

I cannot achieve that - I open up track manager, select a track in the archive section - pick red for track colour - open with "view map". There is the track. Repeat for a second track, changing to blue for eg., open with "view map" - and all I get is the screen showing the last track, not the previous one. Even though the tracks are in the same localised area.
Bemused!
Enlighten me some more and many thanks.

Hi Seldom,
Thank you for the reply.
Selecting all the tracks -  only one track at a time can be selected to show on the map as far as I can see.

Another way to solve your problem, if you have shapefiles, would be to import them into GPSmapedit and make a transparent map of your area of interest.

- I would really like to know why it "works" on one unit and not on the other. I do not wish to have shape files with multi parts converted into a overlay (effectively a custom map) - it defeats the reason that .shp maybe converted into .gpx.

I have both a Garmin GPSmap 60Cx and a Garmin GPSmap 62s.
I wonder if anybody can advise on the following:

I have created a .shp file in QGIS representing a section of woodland. The different areas of trees have been indicated by polygons (only the boundary showing – no infill).
The shape file was transformed using DNR Garmin into a .gpx file.
This file once transferred on to the GPSmap 60Cx unit showed perfectly as a complete representation as in the original .shp file – in its correct geo-position .i.e. ALL the individual polygons upload and show on the screen together. The .gpx file contents are evidently dealt with together as one unit.
The .gpx file once transferred on to the GPSmap 62s unit (perfect transfer) was then looked at. Surprise, the polygons were showing in the archived tracks as individual "units". This resulted in 64 "tracks", one for each polygon unit.
Each unit was able to be shown on the screen – but there was no way to get all together to show the overall plan of the woodland section – only one unit at a time. It was as if the GPS unit was only able to place one track on the screen at a time.
My question is:
How is it the GPSmap 60Cx unit is able to perform and show all at once, whereas the GPSmap 62s could not (or would not)?
I already have an underlying .kml file showing as an overlay (aerial photo) of the area since the woodland is so dense rendering the simple" topo" representation near useless.
Any advice on how to overcome this problem would be welcome?
Thanks,

Peter

General Discussion / GPS tracks and tagged videos
September 10, 2011, 03:12:49 PM
Hi Guys,

Quick explanation of my "wish list".
I am presently putting down a track - maybe 500 metres long.
That track is archived as a GPX file.
I then attach the same GPS unit (Garmin GPSMap 62s) tothe harness of my German Shepherd Dog and she then follows the track that I have laid (several hours later).
Her track is also archived as a GPX file.
Both of the files are then used in GIS software and overlaid an aerial photograph.
The accuracy of the dog to track the original track is then possible (with ability to see tracking behaviour).
What I would like to do is using a headcam (or equivalent) - video the dog during her tracking.
Then link the video image to the GPS track.
As the track appears in the software - have the video image run in sync.

Not too much to ask is it?
Any Open source possibilitites out there.

Thanks for any leads,

GPSr Units / Track on Garmin GPSmap 62s
August 03, 2011, 06:03:07 PM
I have an annoying problem which I hope is easy to fix - by somebody who knows how!

Wishing to verify how accurate my tracking dog tracks a line that has been laid down - I wish to use the GPSmap 62s.

Having loaded a relevant aerial photo, I proceed from my house (with unit turned off), walk approx 200 metres to the position where I wish to start to lay the track.

Turn on the unit, lay track (500 metres approx) - name track and save on unit.

Here is the issue. A "track line" is showing from the home to the start of the track has been added on to the track. Also, even though I had turned the unit off at the end of the track (after saving it) - the track also shows a direct line from end of track position to the house!

How do I stop these "extra" beginning and end sections being present?

Any advice is most welcome
