Hi Menion,

- What elevation data exactaly are you using for your LoRouter online? And are these the same files which LM4 useres are downloading for using LoRouter offline?

- A very important advantage of Locus against its competitors has always been its offline skills. Very important when hiking/cycling where no Internet is available or being abroud where Internet is too expensive.

I personally use BRouter in LM3 offline all the time. It delivered the best elevation sums of all apps until about half year ago. Since then LM3 (and maybe also LM4 using Brouter, Graphhopper) changed something to the worse (see linked thread above) and we do not get good elevation sums anymore although we have installed the best elevation files available in Locus "SRTM"-folder (Sonny 1" DTMs).

So our request: please change this behaviour to how it worked in the past, namly on-the-fly use of precise elevation files within "SRTM"-folder to calculate elevation stats when using other route planers (e.g. BRouter) than LoRouter.

Maybe an interesting improvement for Locus user and developers: "DTM Czechia v2" has been released which is based completely on precise LiDAR data.

[few new DTMs have been released]

Just an update:
Quite a few new DTMs have been released during the last months, especially in Middle- and Eastern Europe.
Have fun with them!

[Norway_Mainland]

During the last months I worked a lot to create new DTMs, now they are available:

Norway_Mainland v2, Norway_Svalbard v1, Norway_Jan Mayen v1, Denmark_Faroes v1, United Kingdom v2, Ireland v1, Portugal_Mainland v0, Portugal_Madeira v1, Portugal_Azores v1, EUROPE v18

Have fun!

[Germany]

I created new DTMs of Germany and Luxembourg
Download: https://sonny.4lima.de

For Germany I used new LiDAR source data of Hessen and Bayern. And the quality of Baden-Württemberg, Saarland, Niedersachsen, Bremen, Schleswig-Holstein, Mecklenburg-Vorpommern got significantly improved, especially in wooden areas.
For Luxembourg I used finer LiDAR source data.

Have a good time!

I'm not sure if Locus is able to read or unzip .zip-Files.
But I can tell you a useful tip to bulk unzip files on a PC: I'm using software "WinRAR", mark all files I want to unzip, right mouse click and select "Extract Here" from the menu. Now all files are unzipped into the same directory

My Xiaomi Redmi Note 9s has just upgraded to android 11, but I'm now unable to connect to ant+ devices (it was working perfect on android 10). When I try to connect a device, Locus (4.12.1) tells ant+ is not available on the phone. I've already checked all ant+ related packages are installed

I'm using a Xiaomi phone myself, and as far as I know Xiaomi is no longer supporting Ant+ since Android 11. Ant+ in general is a dying out technology, even latest Samsung phones aren't suporting it any more.

I regularly open the forum by its "unread posts"-link. With the updated forum I noticed that topic themes are not emphasized, but the poster starter of the thread is.
For a better readable layout I would recommend to emphasize the titles (e.g. by bolding and/or coloring in orange) and remove the bolding of the original thread starter.

Possibly the same issue: https://help.locusmap.eu/topic/27665-track-recording-add-point-behaviour

Bitte keine Google-Drive Links posten, diese können sich ändern, ich erhalte auch jetzt schon zuviele Anfragen, die bei Google Drive ins Leere laufen aufgrund von falschen Links die irgendwer ohne Zustimmung gepostet hat.

Solange das opendata.at Portal noch aufgrund von Umzug offline ist, könnt ihr mich gerne per PM um bestimmte DTMs bitten. Wenn es Neuigkeiten dazu gibt, erfährt ihr das auf meinem Twitter-Kanal.

Weitere Fragen bitte direkt im Thread https://forum.locusmap.eu/index.php?topic=5363.0 posten, danke

There's no GPX-standard, cause Groundspeaks' .gpx files always just contains the Header-coordinates or the corrected-Coordinates in its <wpt>-Tags. Groundspeak delivers both coordinates just via API (="Update caches" in Locus)

So you can define an additional tag on your own. GSAK for example (which Locus is able to import in a correct way) notes the Original coordinates following way:

Code Select Expand

<gsak:wptExtension xmlns:gsak="http://www.gsak.net/xmlv1/6">
      <gsak:LatBeforeCorrect>48.123456</gsak:LatBeforeCorrect>
      <gsak:LonBeforeCorrect>14.123456</gsak:LonBeforeCorrect>
</gsak:wptExtension>

So Locus could for example create an additional:

Code Select Expand

<locus:OriginalCoordinates lat="48.123456" lon="14.123456" />

[Austria]

There's a new version (v2) of DTM Austria, my oldest DTM. Therefor I downloaded the latest LiDAR source data of Austria's federal states.

Additionally I created 2 models with finer resolutions (10m and 0.5"). These fine gridded models will kept limited to Austria.

[Poland]

By the way: There's one European country left which offers precise 1m-OpenData Lidar source data: Poland.

But it's not possible to download the enourmous data for the whole country due to the limitations in the download methods. I already contacted the Polish office (GUGiK), but they seem not willing to improve their download methods nor offering an alternativem less dense gridded DTM (e.g. 10m) for the whole country which would result in an ideal file size to download.

If somebody of you is interested in a Lidar-DTM of Poland, you could contact them too, to make them understand the request for a countrywide download of their elevtion data.

[Germany]

I created new DTM of the whole of Germany. Not each federal state is offering OpenData elevation data yet. Please open the image "_Sources.png" in the download package to check the type of Sourcedata for each region.

Furthermore I created a new DTM of Slovakia, please check:

https://data.opendataportal.at/dataset/dtm-slovakia

[Swiss DTMs]

I created a new Version of Swiss DTMs, with great improvements in large parts of the country:
https://data.opendataportal.at/dataset/dtm-switzerland

They are based on new high-quality OpenData sources of Swisstopo.

By the way: I created a Twitter account to post news and answer questions. If you want me to follow:
