Problem for big areas

[MichARom]

Hi,
I discovered ScenProc few weeks ago, and I have 2 questions.

I did a first test who worked, and now I have some problem with bigger areas.
I try now to create the autogen for the whole Switzerland, using the batch mod.
To do it, I use a file from OpenStreetMap downloaded from https://download.geofabrik.de/europe.html, who cover whole Switzerland.
I use this code:

ImportOGR|switzerland-latest.osm|@0@|building;landuse|NOREPROJ|DONTPROCESHOLES

SplitGrid|AGN|*|*

CREATEAGNPOLYVEG|FTYPE=POLYGON AND landuse=forest|{8EF6A032-8AA8-48F0-80EA-90A16B3696DD}

CREATEAGNGENBUILD|FTYPE=POLYGON AND FAREA>40 AND FAREA<200|{5ae04eb6-934c-4f63-bb48-5e7dee601212}|MAXRATIO=3

CREATEAGNGENBUILD|FTYPE=POLYGON AND FAREA>199 AND FAREA<400|{4db228d2-73d7-42ba-b2eb-c76a743f05d1}|MAXRATIO=5

CREATEAGNGENBUILD|FTYPE=POLYGON AND FAREA>624 AND FAREA<1000|{e206cd08-5008-4dea-ad4a-db42bfa5298b}|MAXRATIO=30

CREATEAGNGENBUILD|FTYPE=POLYGON AND FAREA>999 AND FAREA<1600|{e206cd08-5008-4dea-ad4a-db42bfa5298b}|MAXRATIO=50

CREATEAGNGENBUILD|FTYPE=POLYGON AND FAREA>1599 AND FAREA<3625|{e206cd08-5008-4dea-ad4a-db42bfa5298b}|MAXRATIO=50

EXPORTAGN|FSX|D:\AUTOGEN

The problem is when I use a LOD of 9,10,11, the program can't open the file, and it keeps reading the file (it didn't write "importOGR" after the loading bar.
But when I use a LOD of 8,7,6, the program says "Skipping feature: too many tags in node" and I don't have anything in my autogen...

My second question is: Is it possible to add cable car and things like that??

Thanks for your help and sorry for my english

Hi Michael,

Those warnings about too many nodes happen sometimes with OSM files. Some features might not be read, but the majority should. So the rest of your script should work normal.

How big is the Switzerland OSM file? Depending on that and your memory you can choose in how many segments it should split.

Adding cable cars might be possible. You need to add scenery objects for the pylons and then you can place them (as autogen or bgl).

Thanks for your answer.

So the Switzerland OSM file is 6.6GO, and I have 12359MB of RAM.

Now I have this error... 12:37 IMPORTOGR Error Too many tags in relation 2202162

Do you think that using an osm splitter is a good idea? And do you know one?

Thanks for your help

Hi Michael,

I have never used OSM splitters, so I can't advice on a good one.

But the kind of errors you get (they come from the OGR library), should not really depend on the LOD you read. They should always happen when those elements are read. So I'm not sure it's part of the problem. Depending on the size of the area the import will take longer.

Hi, Arno
I understand what you say. But do you know how I can resolve this problem of skipped tag??

Thanks for your help

Hi,

The Ogr warning is normal, I also get it sometimes when running osm data. You should be able to ignore it. I'm not aware of ways to prevent it.
