HTTP response 400 -- Question

[Guest Bronko]

I, not too long ago, had TileProxy running satisfactorily at LOD 17 (Level 19). I have since done a complete re-install including the OS (Windows 7 Ultimate 64 bit), FSX with Accelerator and TileProxy. I am using the same FSX.cfg file from my prior installation. I am now getting the following errors starting at LOD 16 (Level 18): nettile: Transfer #45 received HTTP response 400 (http://us.maps3.yimg.com/aerial.maps.yimg.com/img?x=48897&y=28853&z=0&v=1.9&t=a) nettile: Transfer #47 received HTTP response 400 (http://us.maps3.yimg.com/aerial.maps.yimg.com/img?x=48899&y=28853&z=0&v=1.9&t=a) nettile: Transfer #48 received HTTP response 400 (http://us.maps3.yimg.com/aerial.maps.yimg.com/img?x=48900&y=28853&z=0&v=1.9&t=a) The appropriate parts of ProxyUser.ini (I think): max_lod=17 preload_min_lod=9 preload_max_lod=17 network_module=libnettile module_config="conn=20|rate=2.0|verbose=0|server=http://us.maps3.yimg.com|path=/aerial.maps.yimg.com/img?x=%x&y=%y&z=%z&v=%v&t=a|useragent=Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 1.1.4322)" min_level=9 max_level=19 map_version=1.9 level_mapping=9,10,10,11,12,12,13,16,17,18,19 color_hack=No color_level=0 bulk_extend=50 As I said, this used to work great. I am wondering about the "z=0" value in the URL and the values of x and y. Directly entering the URL in FireFox results in an "Invalid Request" response. Modifying the x, y and z values will result in the return of an image. But when I change them, I have no clue where I am. Here are some URL values from about the same place I'm flying: http://maps3.yimg.com/ae/ximg?v=1.9&t=...mp;z=18&r=1 http://maps3.yimg.com/ae/ximg?v=1.9&t=...mp;z=18&r=1 http://maps3.yimg.com/ae/ximg?v=1.9&t=...mp;z=18&r=1 Any thoughts? If I have forgotten to provide some pertinent information, let me know. Thanks, Bronko

Bronko,it's entirely possible that (a) the particular tile is absent or corrupt - it happens.(:( you've crossed a boundary into an area where there isn't any level 19 tiles.New York and the LA basin may have a lot of 19... if it works there, there's nothing wrong with your settings...Christian calls the 1m (level 19) experimental as if he wasn't sure it would always work - it seems to the few times I've tried it but you never know.Loyd

Loyd, You're correct. I do understand about what is and isn't available; that's why I quit flying in the Caribbean, there's no high res stuff there at all. But that's okay, I understand the whys and hows.What has me wondering is why is the z value in the URL is zero instead of eighteen (The errors occurred at LOD 16 - Level 18)? Also why are the latitude and longitude values so different between TileProxy and Yahoo? I just figured out about the Latitude and longitude: they are twice the value at Yahoo, which indicates one level higher than what Yahoo is showing. That would be correct for this particular location if TileProxy where asking for level 19 because level 18 is the highest resolution available. But, I trapped these errors while filling the LOD 16 buckets. So, it's back to where did the z value come from?Also, these errors occur EVERY time I re-start TP or refresh the scenery, no matter where I might be.Bronko

Bronko,it's all one great mystery...why does something start working differently...If it were me, I'd try one easy change to see if it made a difference:since TP only 'operates' on 10 ranges while allowing you to specify what level you want for each, try adjusting the min/max and mapping to just show a range of 10 instead of 11 elements. set 10, 19, and 10,11,12,13,14,15,16,17,18,19 and see if it changes anything. If not, then I have no other ideas about it...Loyd

[Guest Bronko]

Loyd, what you just said makes sense. But what about the folks that have min/max levels of 5-19 and then level map 15 levels i.e.:level_mapping=5,6,7,8,9,10,11,12,13,14,15,16,17,18,19Bronko

Bronco,I've tried those 'extended' configurations a time or two but I really think it has minimal effect (unless your internet speed is very slow).TileProxy is going to build scenery elements for the lowest resolution (first oval, LOD8/QMID10) that are exactly the same size as an LOD8/QMID10 region.Every one I've ever seen is exactly the same size, whether I 'fed' it with level 5 tiles, or level 8 tiles or level 9 tiles or level 10 tiles or even with level 11 tiles.The scenery created from different resolutions ends up the same filesize and the same resolution. What you might see, and the ONLY reason I would use this technique, is if I did not like the image coloring at level 10 - normally the lowest res - but would have preferred the coloring from the level 7 imagery. Then I would use it for the remote level 10 and 11 rings (which are stored in the .FLAT files in the scenery folder)You should experiment with different .ini settings using a "fresh"/blank Texture folder. Otherwise you will start overwriting all that exists in the folder you are using. If you flush the Scenery folders frequently, then this is not an issue as little will be lost.Loyd
