Re: [Flightgear-devel] Problems with terragear and building Australian scenery
Hi Jason, Not sure why you did two posts of the same thing, but... Maybe it is political? You do know that the 'missing' DEM information is Capital Hill, Canberra ;=)) Tile e140s40/e149s36/5393832 is centered lat,lon -35.3125,149.125 and in Google Earth that looks like 'Capital Hill' ;=() Seriously, you show you have - 5393848 -35.0625,149.125 through to 5393851 -35.0625,149.875 so your DEM data sort of runs out at -35.0625, while you want down to -35.3125... You do NOT say WHERE you got this DEM information from... That is, what DEM/SRTM 'raw' data did you start with? Where did you download it from? What TG tool did you use to 'chop' it into .arr.gz? With this information, may be able to help more. Regards, Geoff.

Re: [Flightgear-devel] Problems with terragear and building Australian scenery
Geoff, sorry for the double post, but I thought I had issues with my old and new email address. Anyway,the original hgt source was from e0srp01u.ecs.nasa.gov/srtm/version2/Australia This was 'wget' from the site back '06 and unfortunatly not available now. I am cutting up the hgt file with 'gtchop 1 HGT/S38E150.hgt SRTM2-Australia-3/' and it shows no errors.

There's your problem - the data is 3 arcsec, not 1, so effectively you've shrunk it to 1/3 of its original size. Re-run hgtchop with 3 instead of 1.

Re: [Flightgear-devel] Problems with terragear and building Australian scenery
Geoff, part of my plan is try and incorporate mif topo's into the mix of elevation. I had a script somewhere that used Fred's fgsd xml format to overlay the topo's elevation data on a tile and then export from fgsd to build a new tile :) Jason On Sat, 2009-04-04 at 14:36 +0200, Geoff McLane wrote: On Sat, 2009-04-04 at 13:11 +0100, Jon Stockill wrote: Jason Cox wrote: Geoff, sorry for the double post, but I thought I had issues with my old and new email address.
