The elevation data for Europe are now very accurate in many areas thanks to flight laser scanning.
Wherever these data are freely available, @Sonny collects them, checks them and interweaves them with Jonathan de Ferranti‘s Viewfinder panoramic elevation data in the areas not yet scanned.
The result is a constantly growing set of elevation data, the best that could be achieved without paying licence fees at the moment.
The accuracy is good enough to make sense for contour lines at 10 meters vertical distance. (which was definitely not the case so far).
To make a long story short:
The following maps are now available with 10m contour lines (more will follow):
Alps, Alps_East, Alps_West, Pyrenees, Austria, CanaryIslands, Corse, Czech_Republic, Great_Britain, UK_Scotland, Ireland, Madeira, Mallorca_Ibiza, Malta, Sardegna, Sicilia, Slovakia, Slovenia, Switzerland, Luxembourg, UK_Wales, UK_LakeDistrict, UK_IsleOfMan, UK_Shetlands
New and updated Maps:
The Alps-West now also includes the neighbouring Rhone Valley.
New map: BalticStates (Estonia, Latvi, Lithuania as complete map)
More and more boundaries are grouped in relations and thus cannot be reliably processed by the MapsForgeWriter. In the meantime this is like a TikTokChallenge = who manages to create as many completely unnecessary relations as possible. At the islands of the Canary Islands and Madeira, every beach on even the smalest islands is occupied by countless border relations – these have to be filtered out with great effort.
That’s why I have now written this relation resolution from scratch for
boundary=administrative and Admin_Level=1 to 4
Means: national borders and federal states.
…and try to filter out the nonsense relations…
Extreme improvements were made for maps of South America, here even national borders were missing.
The Locus version of the POIs is now finally relesased and included in the map downloads
A separate download of the POIs is not necessary
The result exceeds all my expectations – I use this feature on most of my trips. Never before it was so easy to find the nearest drinking water source on long bike-trips (eg)
As always, I strongly recommend – especially for Locus – to download the map via quick installation. The POIs and the latest version of the render theme are installed in one go.
Even I do it this way – it couldn’t be more comfortable and safe.
The naming convention remains as described in the previous post:
- [name]_oam.osm.map (= the map file itself, appears in the Locus Map Manager as [name oam])
- [name]_oam.osm.db (= the POI file for Locus, ORUX users can delete it)
- [name]_oam.osm.poi (= the POI file for Oruxmaps, Locus users can delete it)
If you participated in the BETA test of the locus-pois, please delete all poi files, empty the cache and then install the new maps+pois. Reason: The BETA-pois were partly buggy and the fragments in the cache disturbs the operation of Locus.
How all this works, incl adding the POI button to the right function-panel + cache_delete you will find
Why does this happen:
The current Elevate version 4.4.0 is optimized for Mapsforge 0.12 and higher, which now supports curved path texts. E.g. contourline captions, street names and route refs use this. But this kind of rendering doesn’t work so well in older Mapsforge versions, e.g. all current non-beta releases of OruxMaps. OruxMaps Beta uses Mapsforge 0.12 since 6 months, but it’s a really long beta period, so still no final release. I wanted to release Elevate 4.4.0 after the beta phase is finished, so there was a long time only a release candidate for Elevate 4.4.0. But now there were too many changes in the maps that it was time to release it. Especially the data in the maps for protected areas changed, so users complained that Elevate 184.108.40.206 wouldn’t show those anymore.
But there is still no end in sight for the OruxMaps beta phase (and maybe other apps still use an older Mapsforge version). So I decided to update Elevate 220.127.116.11 to 18.104.22.168 and release it as a legacy version. The only change is compatibility for protected areas with maps from 03/2020 or newer.
[Edit: this has been solved since OruxMaps 7.5.10 (only available via Playstore)]
