Maps Etc. are Laterally Stretched When Viewed in Basecamp?

Hi,

I'm new to the Garmin forum, (and to GPS usage in general), so hope that this post meets with forum rules.

I'm using Garmin Basecamp on a Windows 10 Desktop, in conjunction with a Garmin GPSMAP 64s.

When basecamp is opened, and the GPSMAP 64s is connected to the computer, (and recognised by Basecamp), all maps, Birdseye satellite images, and Birdseye Select downloaded maps, etc. etc., are correctly proportioned on screen.

However, when I open Basecamp on the computer, (and the GPSMAP 64s is not connected), all the maps, Birdseye satellite images, and Birdseye Select downloaded maps, (as stored in "My Collection" folders), appear laterally stretched on screen.

i.e. each individual map grid square on British Ordnance Survey maps shows as a substantially oblong box rather than the correctly proportioned square that it should be.

EDIT - I've added comparison images below, in order to show what the problem is: -

Correctly proportioned when GPS connected -

Laterally stretched when GPS not connected -

Is this normal? (Perhaps something that Garmin have incorporated to prevent copying & pasting of maps?), or is there something I've perhaps not set correctly that would allow the maps to show correctly?

I was hoping to be able to create routes/tracks etc. using Basecamp alone (without having to connect the GPS itself to the computer every time), but with the "stretched" mapping that is on view, I'm not sure if such tracks/routes would then be properly aligned with actual paths on the ground, when transferred at some later stage to the GPS unit.

Any replies / clarification / suggestions will be much appreciated.

Regards,
Mike.
  • I just discovered why this stretching is happening. It is a setting in the map controls. (where you select magnification, directions; at the top left of your map (probably)


    Well it's more than this but certainly a rotation here won't be helping.

    A few minutes ago, I edited my last post on this thread (#10 on the thread at the time, posted yesterday evening - British Summer Time), to correct a typo.
    The edit seemed to work, and the word was shown correctly spelled.

    However, I now notice that the entire post has disappeared from the thread.
    The header text at top of page is showing 13 results, but only twelve are visible.

    - Rather strange.

    Hi,

    Thanks for that. The post is now visible again.

    Strange though, that the post was visible (prior to your approval ??), as I was able to spot the typo and correct it - before the post disappeared.

    Getting back to the topic in question, and having further pondered on the "problem".

    It's certainly much more of a distortion of the images than could be put down to a Mercator projection adjustment. (See attached composite image of Great Britain showing the extent of stretching).

    I have a sneaky suspicion that the stretched maps might actually be a marketing strategy by Garmin - to ensure that Basecamp can only be used with Garmin GPS devices.
    (I can't prove that, as I don't have a GPS of different manufacture, but it would explain what was happening).

    The maps show correctly on the GPS, and also show correctly within Basecamp, provided that the GPS is connected to the computer at the time. (i.e. that is all maps both in "My Collection" and on internal storage and SD card within the GPS).

    That being so, it's quite obvious that Garmin can show the correctly proportioned maps when they want to.

    Could it be that Garmin have purposely introduced some coding within Basecamp that actively searches to see if a Garmin GPS device is connected to the computer, and only show correctly proportioned maps when there is?

  • It's not that. I have some non Garmin as well as Garmin maps that show perfectly correctly in BaseCamp without any GPS connected.

    As for moderation, you can see the post until you've finished editing and before the algorithm used decides it's worthy of moderation.

    FWIW, I just tried the same thing using the Global map on my iMac. The proportions remain incorrect and never change whether the Nav-V (Garmin BMW OEM Zumo-like device) is connected or not.

    Just installed a fresh Basecamp 4.6.2 and installed my BMW Navigator V .
    The maps are indeed definitely stretched, even in 2D, no matter what map I select (Global or City Navigator Europe) and with or without the device connected ..
    When zooming out, it is obvious that the map projection is indeed not corrected (see near the poles), and I don't even imagine planning a trip in Iceland or Norway, where a circle around a point becomes a fat ellipse.
    But even here in Western Europe near N50°, familiar shapes (of roads, cities, etc.) become so distorded that visual trip planning becomes uncomfortable or even impractical.
    I reckon there should be a simple "tilt" control in the currently unused area (e.g. small middle circle) of the map control buttons to correct this at user will.
    Please Garmin, please listen....:rolleyes:
  • Until then use the program I linked to above.
  • Can just Line up her and adress this to Garmin: today 20220311 this issue still remains..

    said that you guys at garming haven’t even bothered to close this trouble… :(

  • I say the same thing as the Creator of this thread basically isn’t saying straight through:

    Its a shame that Garmin can’t fix such a fundamental issue.


    It isn’t a need of a hack, what your tip is about IS a hack!

    What your hack is about is just as simple as a workaround instead of fixing the real problem.

    Workarounds are ONLY made up because of someone’s lack of interest of doing things the RIGHT way.

    even called unprofessional layzy people don’t know how to fix issues correctly.

    I don’t even bother to comment your lack of interest in “it has never bothered me”.

    I just don’t know why I am supposed to pay for things that just doesn’t work. Shrug tone2
