Doug , you made it sound (to my non scenery building mind) like this thing just goes off and puts trees and things where they should be ... you said its been running for 12 hours now ...what is it ?
Yes, there's a guy in the Netherlands, Arno, who runs the FSDeveloper.com site, and he builds some tools which revolutionise scenery development. In this case, the main tool is Scenproc, which is a procedural scenery builder -- you feed it data, and it creates autogen, or non-autogen placed objects. I did a
blog post about this toola long time ago, but since then it has had a lot of features added. Arno is constantly working on these tools, and he is always finding ways to improve the automation.
It does rely on available data, to a large extent, and there isn't always data available. For instance, for Wellington I used Scenproc with the Wellington building footprint data to place nearly every house in Wellington automatically. Normally I'd do this by drawing a footprint for each house, which can take months for a typical scenery, so being able to automate this is a godsend. However there are only building footprints for Wellington and Christchurch, so the rest either need to be done in Annotator, one by one, or we need to find another way.
One other way is to have a way of determining what's what from the aerial imagery. Arno has been working on this for ScenProc, and he is getting to the point where it can be very useful for placing buildings automatically. I haven't tried this yet, as I still tend to hand-place, but one day we'll get to the stage where you can feed it an image, and it'll create all the buildings and vegetation.
LINZ does have some very nice vector data for vegetation -- for instance, you can download a vector file for all the major native bush coverage in NZ, and Scenproc will create autogen from this. I use this for the Subscription -- there's always a 'first pass' where I use scenproc to place the large areas of vegetation, then add the rest by 'hand'.
