That's not a problem, but a feature. Really. After mirroring
an object you have to 'apply the rotation'. (Some key combination
with a, IIRC. Ctrl-A?) I don't know why this isn't done

This looks quite detailed. I'm not that familiar with the London area so 
would you say that there is a considerable amount of smaller streets 
missing in there?


Even with not so much detailed streets - i.e., leaving all the 
back-streets out and having only freeways and mainstreets processed - 
the generation of scenery takes substantially longer than for the 
standard data. I have no numbers on this, but having to raise the 
resource limits in fgfs-construct considerably is quite a good indication.


One other problem that'll probably become more serious with more 
detailed street-data is that the comparatively small streets not only 
produce lots of small triangles on the streets themselves but also raise 
the number of triangles on neighbouring polygons by splitting them. 
(Currently fgsd crashes on loading some of the more full tiles - 
possibly because of the sheer number of triangles; I will investigate 
further on that when I get the time)


I currently do not have any solution for that and I know that there have 
been discussions before, but perhaps having more detailed scenery now 
may be a good reason for the experts here to reconsider this topic.

Anyway recombination will only partially solve the problem, as on an

Perhaps we need a better way of making polygons from lines, much like 
the v.buffer operation of GRASS

You can see the source data here: http://www.openstreetmap.org/ there 
are roads missing, simply because the map is not yet complete, nor are 
they categorised. Once there's some more data, the segments are 
correctly joined into roads, and the roads are classified then we can be 
more selective about the roads we include in the scenery.

Yes, the cpu limit was set as 120 seconds - I increased it to an hour 
and *still* had failures, so it's now set at 4 hours here just to be safe.

I've not had that problem yet, but so far the data only covers a 
relatively small area.


I currently do not have any solution for that and I know that there have 
been discussions before, but perhaps having more detailed scenery now 
may be a good reason for the experts here to reconsider this topic.


We've just been discussing another problem on irc - the green texture 
isn't really appropriate for a city, but I left out the city areas since 
the texture it uses contains its own roads. I'm not really sure of a 
solution to this.


This may be solvable by automatically snapping endpoints and recombining 
shorter segments into longer segments.


It will be solved in future versions of the openstreetmap data - at the 
moment it just exports as lots of short roads with a start and end 
point, eventually these will be chained together to form longer roads.


Anyway recombination will only partially solve the problem, as on an

Perhaps we need a better way of making polygons from lines, much like 
the v.buffer operation of GRASS 
(http://grass.itc.it/grass61/manuals/html61_user/v.buffer.html).


At the moment I'l just converting the exported openstreetmap data to the 
tguserdef format, which I suspect is less than ideal. It may be worth 
having something that will be a bit more intelligent, and resolve some 
of these problems as it parses the data.

That's really impressive Jon! 

I have a feeling as we get more road data, we're going to be seeing slight 
placement errors at the airports. Currently EGBB is placed over the A45 on 
the 0.9.8 scenery. If I can get that road mapped by GPS and a few others 
around it, we can probably move the airport to its correct location.

EGBB is spot-on in it's placement - the vmap0 road data is far worse.  If you 
map the road with GPS around the airport it will sort the problem there.

I noticed that a lot of airports in the X-Plane DB are quite far out.
Even some major airports like Sion were out by ~ 3 km.

What I do find interesting is that the quality of the data seems to change for 
every country.
South Eastern France's data was horrid, so was Switzerland's however Italy's 
data was almost spot on more than 90% of the time.
Maybe someone corrected the data for Italy already or maybe it came from a 
different source.

Also it appears that a lot of the data was pure guess work in a lot of cases.
I saw plenty of runways that were more than 20 degrees out, runways that were 
more than 50% too short, wrong runway id's, wrong surface types, etc.
Ever seen a military airport with a single 500m long grass runway that they 
use for F18's, Mirages, etc?   :)

My understanding is that for the USA, the X-Plane data for runways comes 
primarily from DAFIF.  Taxiways are all hand drawn and placed.  Outside 
the USA the runway data is manually generated by anyone who wants to 
submit new airports, so quality and accuracy is all over the map.

To be honest I don't expect importing a bulk of tiny roads into our
PostGIS-DB to be our primary goal. They are nice to have for those of
us who operate on powerful hardware but the small roads probably won't
make it into the default scenery. We should stuff everything into our
database that we are able to 'classify' in a reasonable way (small,
medium, large, ) and let everyone decide which data (s)he wants to
use for his/her scenery.

I just read that the current release 0.7 of QGIS is able to render
directly into a PostGIS database - this might help a lot.

The interface is explained here:

http://www.openstreetmap.org/wiki/index.php/REST

I used the map command to dump the data, then converted it to the 
tguserdef format in order to build the scenery, but a shapefile could 
just as easily be used as the intermediate format.

Not yet, although the intention is to have a key/value system which will 
allow the tagging of road types, names, numbers, etc. So the 
classifications will be available.

We have to be careful about simply dropping a shapefile into our
landcover database. Wenever we add a road, river or some other data
to the database we'll have to have a look if the respective object is
already represented there.
For example if you derive a road course from the OSM collection with
the intention to add it to the landcover DB the respective road might
already be present there - although likely at the wrong location. Now
you have to make sure to remove the 'old' road.
I expect this process to be fairly easy with a GIS tool that interfaces
cleanly with such a GIS database as PostGIS because with such a tool
you can identify a _single_ object and remove it from the layer.

For other tools that can't interface directly we are building sort of a
batch interface: You could create a shapefile for a specific layer and
define a bounding box around your data. Now as you are going to drop
this data into the landcover DB we have to expect that your shapefile
contains _all_ data that belongs to the area inside the bounding box:
Not only your addition but also the data that has already been there
before - preferrably together with appropriate junctions between old
and new data.
I know that this method puts us at risk to cut single roads and/or
rivers into pieces and I would not reject clever ideas on how to
circumvent this risk  ;-)

The same applies to corrections of the shoreline, city outlines, lakes
or whatever you could think of.

Martin.

Hi Thorben,
as I like this little island-hopper aircraft very much I immediately 
flew it in the sim.

Very nice, indeed.
As it is a work in progress it would be fine if you could have a look at 
the size of the wheels, especially the front-wheel, and the related 
steering structure. The model would look a lot more realistic if you 
could make it much smaller as this is a very important first look 
element of the original aircraft.

Anyway, I thank you very much for developing this wonderful sim-aircraft.

You can get quite detailed aerial photos for most urban areas in the USA

David Luff's TaxiDraw has support for automatically loading such photos 
and showing them in the editor.


However, I'm still searching for free detailed aerial photos for other

Google maps might be of help in this case as well. The photo is not

That's a normal practice outside of North America.

 We've just been discussing another problem on irc - the green texture
 isn't really appropriate for a city, but I left out the city areas since
 the texture it uses contains its own roads. I'm not really sure of a
 solution to this.
Personally, I think green is fine in the near term.  When more models are 
loaded for a city, the city would not appear to be so green.

I think you misunderstood.  I was referring to the taxiways under map mode, 
not satellite mode.  If you go in map mode, you will see that Google got some 
pretty accurate vector data for taxiways generation.

Erik: would be glad to add the jsbsim FDM. My own attempts to get it to work 
got as far as flightgear sucessfully loading the plane but the engines didn't 
seem to run and I couldn't change that even in the internal property 
browser...

Andy/Paul: well, do I get you right, I should flip the normals outside 
straight away when mirroring a mesh?

 As it is a work in progress it would be fine if you could have a look at
 the size of the wheels, especially the front-wheel, and the related
 steering structure. The model would look a lot more realistic if you
 could make it much smaller as this is a very important first look
 element of the original aircraft.

When I made those wheels, i also thought: this 3view must be wrong, those are 
much to big, but have a look here:

http://thorben-mit-th.de/files/comparison.jpg

Although, I agree, that the gear still needs some work, also some stuff needs 
to be tweaked, like the angle of the rudder...

Hmm, by the way, DHC-6-300 doesn't look that bad either, perhaps I will have a 
shot on it when I'm in the right mood.

I have adjusted the FDM to have a higher ascend rate, I am too lazy to upload 
a new FDM but if you want to have more power change 'cruise-speed=200' in 
BOTH PROPELLER sections to 'cruise-speed=150'.

In the next few days I will be quite busy with moving to the city where I will 
go to university, so don't worry if I don't keep you updated daily ;-)

REMINDER: I still need all usefull data you come across on dhc-6 and some 
hints how to do a proper livery... I won't say No if someone (Gabor perhaps) 
had the mercy to do this work for me... I am neither that skilled in painting 
or drawing nor have much fun doing so.

No one gave you credit for your great work... I wonder why, because it IS 
great. I have told you so via IRC, but perhaps this is a better way to do it! 
I encourage you to keep up that kind of stuff and perhaps have a look at 
other existing liveries that need improving! (Not necessarily thinking about 
my Twin Otter here, but wouldn't say No ;-))

I also would like to know exactly how you did that...

Well, I haven't seen the liveries so I cannot say.  However, from the 
screenshots, the liveries look pretty good.

The method that is used to allow multiple livery needs to be done properly 
though by making use of the texture-path tags.  Some modifications to the 
XML's is suffice to allow multiple livery.  Duplicated model is not needed.

 We have to be careful about simply dropping a shapefile into our

Is it possibly to remove the existing shapefile for a certain area from the 
landcover DB? Perhaps the UK landcover generated by Jon via openstreetmap.org 
could be kept seperately until more or less complete and then used to 
generate UK scenery.

Interestingly, I did a bit of poking around the openstreetmap documentation 
and it does actually provide for defining areas such as 
woodland/built-up/lakes etc.

Further to this amateur cartography, it might be interesting to try to start a 
'community' of people in the UK who can use a GPS to map their local area - 
maybe 150 or so 'adventurous' cartographers could get the majority of the 
UK's road layout done in a year or so (being a small island ;) )

 Google has some pretty accurate taxiways for their map.  Check out

Hey, that's a cool application of Google Maps!

Didn't they get the data when they bought keyhole (or so)? (The company
