FSX Is there any GIS sapefile for the autogen tile boundaries?

[Bungo]

Does anyone know of a GIS dataset of the autogen tile grid in FSX for those of us using Globalmapper and GIS data to create autogen (in ScenProc for example)?

cheers

Hi Braedon:


You may find this topic is more likely to elicit replies in the ScenProc forum:

http://www.fsdeveloper.com/forum/forums/scenproc.131/


You may also wish to review ScenProc.PDF regarding use of "SplitGrid" to reduce GIS source data pre-processing workload

Hope this helps !

Hi,

scenProc can make such a file for you for sure. If you give it a rectangle as input, the SplitGrid step will make the whole autogen grid.

But why do you want to have the grid as GIS file?

G'day Arno,

So that I can see the AGN boundaries on a very large PR and work out building height ranges in the different AGN tiles to apply to the building outline poly I have for the city.

I may be missing something in my understanding of how that all works however.

I guess my issue is:
If I have a large PR that covers an entire city and 20+km surrounding, how do I direct scenproc to have buildings with 1-2 levels in one area and 3-4 in another if I don't know where the AGN cell boundaries are with respect to my GIS vector data (which covers the entire area)?

I figured that if I had the AGN areas I could add an attribute to the bulding polys in that area with a height range that I could get scenproc to read and use (??)

cheers

Hi,

You can also just draw a rougj outline polygon of your city in your GIS tool. And then use the AddCellAttributeIfInside step to test if a till is in that polygon or not. Based on that attribute you then select a different height.

I sort of need the reverse... I need to know if a poly/city/building is in (or encompases) an AGN tile, and if so which one and how to specify building heights inside that cell (as opposed to the AGN tiles around it which may have different heights). It would be ideal if scenproc could calculate this from the data. By that I mean maybe a poly around the building outlines with the attribute for height range of that area or attributes within the building poly's themselves, and make an intelligent decision on what heights and percentages to put in the AGN tile value, without me needing to know about AGN tile locations...

AFAIK, you have to specify AGN building height for the entire cell, is that correct (thus the requirement to know where they are relative to my data)?

I'm still preparing the imagery and colour the seasons (currently a 150,000 x 100,000 pixel PSB file stitched together from 2000+ screenshots of aerial imagery) that I somehow need to export and georeference), so I have looked at the scenproc manual and the videos on youtube, but just trying to get my head around it so that I can be ready when I have my imagery done. Thus I may be missing something in my understanding the process.

cheers

Hi,

I don't think you need the reverse logic for what you want. I'll make a sample script to show how it works (and I should put it in the manual as well).

 

[Bungo]

Thanks Arno.

I was planning to do so tonight, but my child doesn't want to sleep right now. So I can't spend more time behind the PC. Hopefully I find some time for it tomorrow.

 

[Bungo]

I'm hearing you there Arno... My kids (lack of) sleep patterns have interrupted a lot of my plans over the years...

cheers

Hi,

It took a little longer than I planned, but I have added the sample to the scenProc manual now. So grab the new build in an hour or so and have a look at section 5.7 of the manual.

OK, wilco.

Thanks again.
