• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

SP imports the two data sets SW_Building WGS84.shp and SW_Building WGS84.shp correctly.
There are 130812 polys in SW_Building WGS84.shp and 130812 have BUILDTYPE=1 added to them, so that step works correctly :)
There are 10282 polys in SW_Woodland WGS84.shp and 10282 have BUILDTYPE=0 and ID=Woodland added to them, so that step works correctly :)
120972 polys then get re-attributed to BUILDTYPE=2, which seems to be ok :)
The ReplacePolygonByBuildingRectangles seems to work ok, processing 7979 polys into 17564 polys :)

Using FROMFILE in combination with FEATCODE seems to differentiate between Woodland areas and Buildings :)
 
You could probably drop the FROMFILE and only use the ID or FEATCODE to differentiate the feature types. That might clean up your script a bit more.

But glad to read you are making some progress now.
 
Cheers Arno, I've completed some classification rules for an urban area which should allow some nice variations of autogen buildings.
Now just need to work applying some polygon splitting to 4 of the BUILDTYPE classifications, without causing overly strange divisions.
Should be possible to sort a decent mixture of roof GUIDS through a mixture of building type, landuse category and size I think....
Many thanks for your early pointers! :) K

That's an area with many challenging shapes indeed. Some of the very complex ones can probably never be represented properly with autogen. But as long as most of the area gets filled it should be ok.
 
Yes you're right, but autogen, and especially procedurally generated autogen, can only ever give a reasonable approximation. Two solutions would be to a) use the really complex building footprints and model them, or b) annotate some of the more complex features by hand to ensure a 'better' feel. One step at a time ! :ziplip:

One thing I have found is that my autogen is slightly out of position in relation to the PR in the sim, probably due to slight errors in the geo information when it was originally compiled many years ago.
I could correct for this by very slightly shifting _all_ my data in QGIS before scenproc processes it, so it ends up aligned with the PR, but I couldn't see any way of doing that from within Scenproc?
Have I missed something there? If not, it could be useful to have an OFFSET Attribute for use with the CreateAGNGenBuild and CreateAGNPolyVeg commands to allow easy and error free minor placement issues to be resolved globally?
Cheers K
 
Hi,

You might be able to use the CalibrateFeatures step to do the move.

How big is the offset you apply and in which direction?

Do you also see the offset if you load the imagery and vector data in QGIS? Else it might also be a coordinate system issue.
 
The data and new Bing imagery in GGIS match perfectly. The coordinates used to compile the now ancient PR scenery were probably slightly out.

The offset required is only a few metres in both Lat and Long. The offset distances required are approx x=10m and y=8m.
It results in buildings in roads etc which is a bit annoying.

The image attached illustrates the issue. The left hand side is from QGIS, showing a pretty good match between image and building data. The right hand side is from annotator, showing the position in red of the autogen buildings placed by Scenproc, and the actual required positions shown in transparent yellow overlay.

If you export the features from scenProc as a SHP do they still align with the Bing imagery? That would exclude problems with the projection inside scenProc.

Yes they do, I don't believe there is a problem with scenproc at all, I think it was the PR scenery was compiled slightly out of its actual position. I was merely wondering whether Scenproc could apply an offset to the agn placement so as to correct for the misaligned PR within the sim (which obviously isn't going to change!)
Cheers K
 
I think the CalibrateFeatures step should let you shift it all. Check the manual. It was designed to position data that has no proper project assigned, but it can also be used to shift existing data by specifying the input and output bounding boxes.
