    Ich wollte Anfang 2019 alle Karten updaten.
    Wenn Du die Südamerika-Karten vorher benötigst schubse ich die Scripts an.

    LG, Christian

    Ein neues Update von Locus wurde eben freigegeben:

    Themes/Styles funktionieren wieder :-)

    OK, done :-)

    Maps for
    Ireland, UK_Scotland, UK_Wales and UK_LakeDistrict
    with 10m SRTM1/V3 contourlines and Major/Medium intervall of 500/50m (ELE_Labels every 100m) are available for regular download.

    The quality of the dataset is in general – well – quite OK, except for the coastlines/cliffs
    I really hope that there will be free LIDAR data available in the future.

    Best reggards

    What will you do about the Shetlands?

    As there is no reliabe 1″ Data I will use the usual fallback to 3″ Viewfinder with 10m spacing.

    However, all this will last a while cause I have to modify the sripts and parameter_sets for _all_ maps cause actually the only parameter for defining the elevation data is
    „1“ – for view1 ans fallback to view3/srtm3
    „3“ – for view3 and fallback to srtm3

    Same for Major/Minor spacings 500/100 versa ???/50
    This have to be changed for all maps to be more flexible in future.

    Zu 99% fehlerhafte Relationen.
    Mapsforge ist hier sehr strikt.

    Doch Germany N+S ist Germany komplett.
    Die Germany MID ist zusätzlich.

    OK, So if I decide to use 1″ in UK I will use SRTMV3.

    However, Make_Scripts have to be (essential) modified cause these are made to use VIEW_HGTs and – as @sonny have matched LIDAR Data into VIEW1/3 an not SRTM – NASA SRTM should be used in UK only.

    So this will take some time.
    And the GreatBritain Map will be rendered using VIEW3 cause of map-size.

    Maybe I will add a UK_LakeDistrict map.
    UK_Wales is alredy added with the current update but in VIEW3 only (so far)

    Best regards

    So, here is a map of Scotland for testing with NASA V3 1″ contourlines.
    (Lake district is not covered – sorry)

    Well, the dataset seems to be fine.
    I had a brief look round the Storr and peaks at Glen Brittle on the Isle of Skye – an area I know quite well.

    @John @Geoffmoz
    Please took a look at this map and compare areas you know from your walks with aerial images if the dataset is OK.
    ‚Cause it would’nt make sense to waste 100MB for a dataset thats „looks“ fine but is’nt much more precise than the smaler one.

    If the NASA Dataset is’nt good I would need someone to download the OS Elevation Dataset and to convert it to HGT.

    As for the OS OpenMaps: IMHO This is pure OS Landranger Raster – clear to be seen when I look at the area round the Storr. The cliffs/crags are Landranger, the forrest at the base is not part of OSM but 100% Landranger (I have my old landranger map at hand and I know that the forrest exists cause I walked throug several times)
    And I’m pretty shure that – if I wouuld manage to install my very first version of MemoryMaps on Win7 – that it is for 90% the same as OS OpenData.

    Hi @sonny,

    Thanks again for support, I downloaded the GB_Dataset from Derek’s site.
    The Interface is perfect fine – just a few clicks to do.
    I will try to feed phyghtmap with this tiles.

    Would it be possible for you to provide missing (three?) tile of the shetlands as 1″ hgt’s?
    If not I will use the view3 data for this area.

    BTW: As far as I see there are serious problems with elevation data and melting glaciers.
    Best to be seen on South_Georgia.
    That’s really scary comparing (not so old) elevation data and nearly up2date aerial images.

    Thanks and best regards
    Christian

    The source for the NASA 3.0 Files is
    https://e4ftl01.cr.usgs.gov/MEASURES/SRTMGL1.003/2000.02.11/
    .. is this the right dataset?

    As for the 10m lines: This will dramaticly increase the file size of the maps.
    And I have to increase tagmapping for indication of 50m- intervals and not only 100m as its actually the case.

    As for 1″ instead of 3″: Increases filesize but I have implemented an algorithm that eliminates unnecessary nodes – still an increase but not by factor 9.

    In general: OS Landranger are among the very best maps available round the globe – I have _lots_ of these maps here right at hand from the time I spent every summer vacation in Scotland.
    Vector maps can’t really match OS Maps – thats a fact.

    OS / MemoryMaps are still top an unmatched.

    I will give SRTM1/003 a try, at least for 20m lines.
    However this is cumbersome cause phyghtmap on windows cant bulk_download the tiles I have to do this by hand, so this will last a while….

    BTW: I’v seen that Shetland Islands are not covered by the 1″ Dataset.

    Best regards
    Christian

    Hmm.. If someone could download the GB SRTM 1″ Dataset and provide it on GDrive he would do me a great favor…

    Do you know why the OpenAndroMap contours don’t have the 10m interval

    The answer is simple: Too much data.
    The size of the map would be too big with 10m lines.

    With OS Maps this is no problem ‚cause these maps are rastermaps – there is no differencce in size using 20/25 or even 10m Lines.
    The OAM of GB uses 3″ Elevation Data for the same reason.

    I will check if it is possible to use 1″ SRTM for UK_Scotland.map in future.
    So far I avoided SRTM and used Viewfinder Elevation Data cause SRTM is notorious unreliable.
    So using SRTM1 / 10m would mean to add LOT of Data/Mapsize and a fine appearence but questionable accuracy – in my experience.

    @sonny
    So far as I know the NASA Data still is based on the 99th SpaceShuttle mission with some German data X-SAR ??
    So with some math enhancement – but still based on faulty data ??
    Or happened there a new scan of the earth in the meanwhile.
    So: Is the „new“ dataset (2015) really new and reliable or the n_th math/interpolation „enhancement“ it was till 2015?

    Best regards

    Hi @Reino,

    Size of the GreatBritain Map for next week is 800MB (not released yet) this is 350MB less than the actual map (new setup of base_levels)
    England map allone would make no sense = 630MB
    UK_Scottland.map already exists.
    Northern Ireland is included in Ireland.map (140MB) , no need for a seperate map.

    What makes sense is a UK_Wales map for hikers – this map will be added with the next „Europe“ update.

    Best regards

    Dann kann man sich doch die Produktion der Germany.map sparen? Irgendwo las ich hier, dass es 6 Tage dauert

    Das wird irgendwann auch so kommen, der Aufwand für die Germany.map ist schon grenzwertig.
    Und ja, es dauert 6 Tage bis die Karte fertig ist.
