New Contourlines for all Maps – and again – Please Stick to Basecamp 4.6.x

1. Yesterdays/Day before Yesterdays map update of the Europe Map has new contourlines - so especially all OSx users - please do not reuse the old contourlines. For Windows the installer throws an error message anyhow.

It took me a lot of time to iron out bugs in the contourline data, convert it correctly to the needed input formats - fill voids and put it together. The Europe map is now the first to be fully based on Sonnys LIDAR data where available (Italy is new), elsewhere the still pretty excellent ALOS World 30m data - and from 60° northwards voidfilled viewfinderpanoramas 3" data. Yes except for the Alps the Viewfinderpanoramas 3" data used to be the common source for all my contourline maps - it's IMHO crazy how much better the ALOS - and of course LIDAR data is in mountaineous regions. LIDAR data is from laser scanning - of course that will be the best possible to attain, however the ALOS data (downsampled from Alos World 5m data to 30m) is where it's not voidfilled by SRTM1v3.0 really astonishingly good in my eyes. Often flatter forest areas are put 5-10m too high (but SRTM and viewfinderpanoramas also have that problem - if a little less) - but especially in rougher areas the accuracy is pretty good.

I've now also put 10m contourlines instead of 20m interval to all European countries that have no summit over 500m altitude (and to some Germany Bundesländer Maps). Else it's 20m.

This weeks map update will be using the new contourlines for most European countries, and some worldwide countries - however only for maps where the contourlines are not a separate download. Next week map update will then have the new better contourlines for all countries. 

Also of course again all contourline maps come with altitude shading and for those countries like Europe continent map where partly contourlines where missing - this should be fixed with the new contourlines.

 

See below for the Matterhorn - the Matterhorn is pretty much data rubbish in most elevation models - due to it's sticky pointyness, usual cloud cover and glaciers. Thanks to LIDAR data it's really pretty exact (compare that to SRTM1 rubbish in Google earth for fun).

2. Again to stress on Basecamp 4.7.0 - Please do not use it neither on OSx, nor on Windows. It is prone to crashes  - and while on Windows MapInstall 4.2.0 which comes with it - will not send maps on Windows, and often crash while sending larger maps on OSx.

On Windows make sure to run both Uninstall and Installation with Administrator rights - and if you have Problems - Uninstall again - and delete all garmin Folders in Program Files / Program Files X86 folders. Your userdata is safe and not affected as that is in your Userprofile / Appdata folder (no  need to delete anything here).

On OSx I'm not quite sure how to check correct full uninstallation - but it should be similar.

    Hello,
    I am missing something about installing the new contour lines, it’s not clear to me where I find mtbeurope.exe to install the new contour lines from the 7z file as outlined in your post on the 27th December.
    Am using a Mac with macOS High Sierra v10.13.6.

  • robiella

    Ok. I unzipped the file eurpoe_contours.7z and now I have files like -img. but in mapsource I can not load them. Where can I display them?

  • robiella

    I downloaded the file of the contours of Europe (europe_contours.7z). How can I display it now?

  • robiella

    I need countours of northwest Italy (plain and hills) with equidistance 5 meters. When will the file for Italy be available?

    • extremecarver

      I will never publish maps with 5m equidistance – because the underlying data is not good enough for that in mountaineous regions – except for those tiles (see copyright.txt) where I have 1″ data fully based on LIDAR data. For italy I used LIDAR where available: https://data.opendataportal.at/dataset/dtm-italy
      and fill the rest with ALOS World 3D – which is not good enough for 5m lines. Even 10m lines would be quite questionable. You could use this data yourself – and using phyghtmap create .osm data from the datasources, then use mkgmap to create yourself 5m contourlines – but I would not count too much on exactness in steep areas. For flat to hilly regions outside of cities – where LIDAR data is available it would be good enough.

    Vielen Dank für die viele Mühe und die tollen Karten!!

    Eine Bitte hätte ich: Könntest Du bitte bei Andorra bei Gelegenheit den Kartenschnitt überprüfen? Normalerweise reichen die Karten bis knapp über die Grenzlinie, so das bei zwei angrenzenden Ländern keine Lücke entsteht. Die Andorra-Karte hört jedoch vor allem im Süden bei der Grenze zu Spanien schon einiges vor der Grenzlinie auf, soweit innerhalb, dass die Überlappung von Spanien das leider nicht auffängt und einige “blinde Flecken” entstehen.

    Wäre supergenial, wenn Du Andorra auch etwas über die Landesgrenze hinaus schneiden könntest. 🙂

    Ganz lieben Dank im Voraus!

    Gruß

    Hallo, vielen Dank für deine Mühen!
    Habe gerade eine Woche in der Schweiz die neuen Höhendaten genossen, da kann man sich schon gut drauf verlassen.

    Könntest du einen Zeitstempel bei deinen Posts einfügen? Ich sehe nur “18:15” ohne Tag.
    Da kann ich nur per Ausschlussprinzip mit den kommentaren und Md5.txt folgern das die Non-Unicode noch nicht geupdatet wurden.

    In 2 Wochen schaue ich mal ob der Mont Blanc gut abgebildet ist 🙂

    • extremecarver

      Doch – alle karten sind mit neuen Höhenlinien – englisch/local language wird immer alternierend geupdated – die Europakarte etwa alle 8 Wochen (aber alle Versionen sind mit den neuen Höhenlinien).

    Hello,
    I use Garmin Express to upload my rides from Edge 800 to Strava.
    This did not work for a while, but is now works after updating to 4.7.0.
    Will upload to Strava work again with 4.6.x?

    Regards,
    Constant

    Hi – Guten Morgen,

    ich wollte wieder mal meine Karten updaten und lese da jetzt über Ungemach mit Basecamp 4.7.0.
    …jetzt verwende ich aber “die ganze Zeit” (dh keine Ahnung seit wann) genau diesen Softwarestand.
    Frage – Wie wirkt sich den konkret die Verwendung von BC 4.7.0 mit openmtbmap_austria_31.12.2017 aus ?

    Ich frage deshalb, weil mir die beschriebene Prozedur des Downgraden sehr aufwändig erscheint und ich daher versucht bin “alles beim Alten zu lassen” – ich habe aber eben keine Ahnung worauf ich durch diese Konstellation verzichte.

    THX in Advance,

    Alfred g

    On a Mac with Basecamp 4.7.0 (with Mapinstall 4.2) I was able to install maps on my device. I installed this versions mid May. But today opening Mapinstall I got a pop up asking me to install a fix, which I did. After the install I was able to install the maps on my device without any problem.
    PS: I love the new contour lines, thanks!

    • extremecarver

      you got an update to 4.7.0? That’s peculiar – which version number is it now? In general on OSx the maps are sent fine – however sometimes (or better quite often) it’s crashing while sending – Mapinstall 4.1.2 on the other hand is very stable. It’s only on Windows where sending maps with 4.2.0 does not work at all anymore (if maps are in traditional .img format).

    Vielen Dank für Deinen Einsatz!

    Habe soeben mein Abo wieder verlängert und nein ich werde bestimmt nicht auf 4.7 upgraden.

    Gruss
    Thok
