Wonder if anybody can recomend a program I can use for creating hiking routes for my Garmin etrex30. It could be nice if the program can use OSM maps or even better if it can use different kind of maps.
(www.geoplaner.com can do the job online but as far as I can see only based on Google- maps)

General Discussion / Looking for a Track-analyzer ("Trip Computer")
« on: June 08, 2012, 03:19:14 AM »
Wonder if somebody know a program which can analyze a trackfile and give me the same informations as the TripComputer on my Etrex 30:
- Speed
- Max Speed
- Moving Time
- Moving Average
- Stopped Time
- Overall Average
Maybee also an elevation profile and a Trip Odometer.  :)

GPSr Units / Conditions influencing battery life
« on: June 05, 2012, 07:08:43 AM »
Starting from an experience this very day I would like to ask a few questions. Today my batteries in my etrex30 died after 2 hours of walking. This morning I placed whati Thought was batteries onl y used a little and the battery icon (is shown when pressing the "light" button) showed 3/4 full. I use a kmz-file in the CustomMap folder in contrast to a vector-map. Also my Recording Interval was set to "Most Often" in contrast to "Normal".
So the questions are two:
1: Is it not possible to trust the battery icon when it tells you your batteries are 3/4 full?
2: Wonder what influences battery-life
- Recording Interval?
- Type of map (kmz more "battery-hungry" than vector maps?
- Other conditions?
Well I've learned one lesson today: NEVER, EVER go for hiking without two extra fresh batteries  ;)

General Discussion / A few questions about showing gpx-track on maps
« on: June 04, 2012, 03:25:36 AM »
I have imported my kmz rastermap and I can show it in BaseCamp. I have a few question (numbered):

Wonder if it is possible to show a gpx-track on top of a kmz-rastermap in BaseCamp
Do you know any other program(s) wich can show my tracks ? I does not necessarily have to be on rastermaps.
Is it possible to show more than one track on a map? (My purpose is to see one/many tracks from a given area).
Also I am doubt about how to document my tracks with photos? The time on my etrex30 and my camera may differ one minute or so.

Greetings from Kokkari - Samos - Greece  :)

{} = folder
files in red = map-files
questions in blue - numbered

The folders in my etrex30 looks like this.....


       {c} - css_files
      {j} - javascriptfil
      {m} - gif_files
      {pdf} - usermanual in different languages
                StartHere.html (choose language of manual)

   {GPX} - contains tracks
      SPOR-01-MAJ-12 211733.gpx
   {JPEG} - pictures
   {Profiles} - profiles


= basic map of the whole world used for generel orientation
= (1) garmin timezone file (I do not know exactly how this works?)
= AFAIK this file is a userfile placed on the microSD. I believe it can be composed of many different maps into on file. Lets assume that this file contains 4 different maps. Just an example.
(2) I wonder if somebody can explain how Garmin controls these maps in this single file?
(3) I know there is something called Family ID?
(4) And how can I as a user choose between the maps included in the gmapsupp.img file?
(5) Which utility program can I use to split my gmapsupp.img into the 4 maps and which program can add more maps into one gmapsupp.img file?

= a map I made by scanning a samos map. If this is saved in {CustomMaps } as shown above I am able to see it.
(6) Is it possible to have more mapfiles in the {CustomMaps} folder and will I be able to choose which one of these I want to be enabled?
I think I have seen somewhere that the user of a GPS unit can use Profiles to select different kind of maps. (7) If that is correct how is this done?

I'm sorry - it is an awfull lot of questions. But I also find that the user manual for eTrex30 is very limitid and in fact not as usefull as I had expected. it is hard to find an answer to all the questions that comes to my nerdy mind  :)

Downloading maps from OSM in the JOSM have to be done in section - if not I will get an error message.
I want to download the OSM data for my greek island Samos and I do this via JOSM by choosing sections of the island - about 1/4 of the island each time.
In JOSM all the data seems to be there for the whole island.
I save this as Data.osm and afterwards convert this file to an IMG file. Then via MapsetToolkit I convert the IMG file to a file that I should be able to see in BaseCamp.
Bu what happens is that I am only able to see the last 1/4 of my island.
Does somebody know how to fix that? Is it not OK in JOSM to download an area in fractions and then expect the whole area to be in the saved data.osm file?

General Discussion / Get rid of markers in Google maps
« on: May 27, 2012, 01:08:02 AM »
When I save af GPX track-file from my Garmin I want to show the track in Google maps. To do this I convert the GPX file to a KML file. Afterwards upload the KML file tol Google Maps.
If I do the conversion in the program "ITN converter" my track is getting "cluttered" with a lot of markers in the first part of my track.
The same problem if I do the conversion in the program "GPSBabel". Again my track is "cluttered" with a lot of markers!!
Somehow the created KML file in these these two programs show the markers and not just the track (as a line = what I want to see).
does somebody know a converter program where the resulting KML file only shows the track as a line and not these disturbing markers. Alternatively: is there a way to get rid of these markers in a KML file (maybee som tack one have to delete in the KML file?)

Best Regards

PS: In Google Earth these markers is not shown!

Map Making Support / Toolkit overview - please...
« on: May 09, 2012, 02:44:16 AM »

New to this map-making I miss some kind of overview of the different toolkits/programs making the job done. I really get dizzy trying to find out how the processes works! But of course this only reveals my lack of knowledge on this subject...


Some of the programs might be outdated? And what about the different file-types which can be used on PC and GPS? It's really confusing...
I would appreciate very much that som guru out there in cyberspace wrote a few lines about how he/she worked with maps. My OS is Windows, my GPS is eTrex30. My goal is to be able to make maps (digitally scanned or via OSM) and to convert these in such a way that I can use the maps on both my PC (in order to see tracks etc) and my GPS.
Thank you in advance. I really apprecialte this forum and all the helping people here!!

Best Regards

I made a new map of a greek island saved as kmz file.
- where do I place it on my Garmin eTrex30?
- Is it possible to see the map when I am not located in the map area?

Hi everybody,

I have just purchased a Garmin eTrex30 and would like very much to load it with an image map of my favorite Greek Island Samos. I can scan a map but would like to know the best image fileformat and the best reslution for the Garmin.?
Also I would like an advice on how to "georeference" the scanned map?
