Difference between Lomaps/OAM v4+?

[Tapio]

Hi theme authors,

I noticed my theme doesn't work perfect with Lomaps. Well, I only test against OAM Mapsforge V5.

Can you tell, what and if there are general differences and what they are about?

Very general: are different assets included into lomaps? Maybe even renamed ones?

thx

Hi,
I'm sorry but could I ask you for more info? What does exactly mean "doesn't work perfect with Lomaps."?
Anyway, some info about conversion can be found in topic https://forum.locusmap.eu/index.php?topic=8427.0


I'm sorry but I'm not sure I can understand the sentence. Could I ask you to describe it more detailed?

I noticed few display differences, same theme displayed on Lomaps vs. display on OAM.

E. g. Screenshot with grey town area is OAM map, without grey is Lomaps.

Or in the last screenshot, only with Lomaps, it displays "Youth Welfare Office" at such a low ZL.

Will find and analyze the xml tags/osm objects when I have some time.

The used tags in OAM and LoMaps are different. LoMaps use almost the same key|value as original OSM tags but as I know OAM uses lots of custom keys|values.

Anyway, the mentioned residential areas are available in LoMaps as `lm_landuse=residential_city` https://github.com/asamm/lomaps-mapsforge/blob/main/various/tag-mapping-xml/tag-mapping-tourist.xml#L946

The original `landuse=residential` will be available in the map in the next version of LoMaps

Contour data is very different, OAM is much more accurate. Lomaps needs to be zoomed in closer to see "meadows" etc. The same with buildings. Some tags are missing. OAM has tricks so that the name on one large object (for example - lakes, islands) is drawn once, there is no such thing in Lomaps. There are no island names if this name is specified not directly ("place=island"), but through "Relations" (type=multipolygon).

If you are using my theme, then you do not currently have the names of lakes (all).

Thx Sergey, kind of, I have forked it (told you in your thread), too many own ideas how it should look

Hi Tapio. As mentioned I really like your new theme. Thanks for all the hard work involved. One suggestion is to distinguish the road/ track surface eg. between sealed & unsealed. Surely something always of interest to the touring cyclist that try to avoid a rough section of road? I have a test POI at S 42° 30.771', E 147° 38.647' (Australia > Tasmania) that I use for comparing new & changed themes. Desert & OS Map themes are the best at showing a difference. I have even modified Desert to make it even more evident, even at lower zoom levels. Surprisingly given LM is targeted to cyclists, it's Hike & Bike theme (mislabeled "LM road" below) shows no difference for the road surface. Maybe something to consider?

BTW I couldn't find another topic specifically on the Tapiola theme.
