Hello Hans,

may you please share here some sample file (probably pack it to "zip" file) and also is there any documentation for this format? Where it comes from? Some more info is welcome, thanks

Hello Menion:

I'm not sure if Hans answered you, but I would be interested in this too and here is an example of a zipped *.poi file from Openandromaps.com. The *.poi file format was apparently developed for Magellan.


Thank you!

Good day William,

are you sure this is data file that Hans talk about? In this case it is SQLite database file and because it's content is based on OpenStreetMaps, I see no reason to support this type of POI file. Mainly because already offer own solution supplied together with LoMaps from Locus Store. Thanks for understanding.

This is like arguing that you do not need to support MBTiles, OruxMaps and many other formats that Locus does, because most of them are based OSM, too.

Agree, it similar (partially), except that MBTiles are probably most widely used mobile map format that also support very nice metadata table, which is huge advantage compare to plain SQLite and OruxMaps on second side support many map projections, not just Mercator as is used in SQLite maps. So both format support something more. It's not case in this format for now. Huge amount of work that this require is another argument against it for now.

I had a look at both data models, Locus POI and MapsForge. There is no magic in either, but Locus is much more complex, as it supports additional functionality.

One way would be to built a little converter that eats MapsForge POI DBs and delivers the POI part of the Locus POI DB.

I currently do not have the time to do this myself (and I would have to amend my skills while "running", too :-).

Yes there is no magic in database, just a little magic in system we have to create it. Anyway I wanted some time ago to publish these our tools we have ... which should be a lot better then creating convertor ;).

That would be helpful indeed!

Hi would be very useful, when I am searching within an original LoMaps POI database I find only city names and just a couple of locations. Nothing in compare to my Garmin maps or even some other OSM based POI's :(


So it would be brilliant (!) to be able to create (convert, import etc.) locus compatible POI databases.

Is there something new to import a .poi file in sqlite format ? I´am a new User and would like to import a .poi file

Is there any progress on this topic?

Honestly I'm not 100% sure what format users want to supports.

  • OpenAndroMaps (MapsForge) POIs format - there is already post from menion in this idea http://help.locusmap.eu/topic/import-poi-file#comment-41330 Basically Locus already offers POIs database (also in sqlite format) as part of LoMaps maps
  • Is it another format? If yes, do you have an example file and information about source?

Thank you

Well, Petr, a year ago there was talk about providing the tool that writes the LoMaps POI database. Then a volunteer could write a script to export from Mapsforge POI DB and feed into LoMaps POI DB creator.

While both, Mapsforge and LoMaps are fed from the same basic data, there is still a difference, and Mapsforge POIs are more current, too.

I see but it's little bit different story in it isn't subject of this topic :)

Hello. Petr, Is there any progress about tool or method that can create own POI file compatible with LOCUS vector (osm) map? I have to create 14,000 point of mountain peaks into osm.db. because that data is not includuded at LoMaps poi DB. I used GDAL tool(ogr2ogr) to create SQLITE3 db for using at LOCUS. but It can't be recognized by LOCUS app. I think LoMaps poi db is much more complicated than mapsforge standard poi file. If You can't provide LoMaps POI DB creator, Would you give me some hint for generating POI file.

Have a good day.

In addition, My 14,000 Mt.Peak point is consist of lat, lon and peak name (originally gpx file)

Can it be possible that these data inserted to Lomaps POI db file?

Let me know howto plz

Hi, the generator works only with OSM data and I can't give you any exact info if we release our script publicly. However peaks are included in LoMaps POI DB. Please see section "Nature > Peak". Peaks are obviously from OSM data. Is it OK for you?

Thank you for answer, Petr. my country.osm.db(LoMaps) have just 1568 peaks (Yes. It's from OSM data)

But I have about 14,000 peaks data from National Geology Institute(not from osm). So, I need method of making POI (.db) file compatible with LOCUS app. Of course I already have base osm map of my country.

Is there any way of inserting my 14000 peaks data into country.osm.db (LoMaps) ?

Hi,

honestly I'm not familiar with MapsForge POI format but LoMap POI DB is also sqlitedb database (with the spatialite extension). In can briefly describe how to "import" the POIs. Are you familiar with SQL inserts and maybe with some scripting?

That would be great - there will be some volunteer, I guess ... :-)

I'd like to notice that we decided to publish the tool for generation POIs DB and Addreess DB. Such task has low priority for us but I expect that it would be ready till end of the summer. I guess that it'll be more useful then some SQL queries.

Thank you very much for your deciding. Petr. It will be very helpful for users to make their own POI files.

Brilliant - first since many years I didn't use Locus during a two week hiking tour (because of two reasons: no offline searching of POIs and OS explorer map tweaking didn't work)...

...would love to get POI databases!

I'm talking of the format offered at mapsforge. As I can use the map files available there I would like to use the poi files offered along with it.

From the analysis others did (parallel thread), there are only few challenges left, like the creation of the blob in the poi.db file. So, there might not be the need to disclose the whole tool, but some isolated functions like mentioned above, that would allow others to do their own homework.
