New freeware meshes of Alps and Himalayas

Recommended Posts

Hi all,since this seems to be the day for announcements of new scenery stuff... ;-)I'm in the process of uploading a couple of new terrain mesh packages. The first one will cover the central ranges of the European Alps and the next set will greatly improve most of the major peaks in the Himalayas. Note that these are "just" mesh files, not complete landscapes like some of my other projects.What is different is that these mesh files are *not* primarily based on the "buggy" Shuttle Radar (SRTM) data that tend to have big holes everywhere where it's interesting, that is on ice-covered peaks and sharp ridges. Instead, I'm using "hand-made" source data that I discovered by chance a couple of weeks ago.Jonathan de Ferranti has been carefully processing topographic maps for a large project unrelated to flight simulation and has kindly given me permission to compile these data into freeware mesh files for FS. Big thanks to Jonathan!Look for the first two files, alpse_fe.zip and alpsw_fe.zip, here in the library soon. More to follow.Preview screenshots are available here - http://forums.simflight.com/viewtopic.php?p=298792#298792 - and that thread also contains a link to an extensive set of comparison images for those wondering whether it's worth the download ;-)Preview screenshots of the Himalayas project can be found here: http://forums.simflight.com/viewtopic.php?t=48520Enjoy!Cheers, Holger

Holger Fantastic :-)The Alps in all their glory is a dream come true. Are you going to cover the whole of the Alps rather than part.PeterThanks :-)

Hi Peter,sorry, I guess my description of the coverage area was a bit misleading. The two packages together actually cover about 80% of the Alps; not included are the lower foothills along the "fringes". Those areas don't have any missing data in the SRTM data and thus there was no need for Jonathan to generate his custom elevation models, which is a very time-consuming process. In other words, any available freeware or payware SRTM-based terrain mesh can be (and should be) used as a base together with our files.Cheers, Holger

I've been waiting for this for a long time! I'm downloading the Alps right now--I guess I know why I finally switched to broadband Internet a few weeks ago! Great work!-JohnEdit: Just installed the first half (the Swiss/French half). This exceeds my wildest dreams! Outstanding effort!One final Edit--link to some screenshots:http://forums.avsim.net/dcboard.php?az=sho...id=225145&page=

I have done some hauls in these mountains a few times quite challenging. I was wondering what would be a good freeware base terrain mesh you would suggest to go with the rest? Thanks A Bunch, Josh

Thank you Holger! I was about to purchase Raimondo Taburet's new 38m Alpine terrain mesh when I luckily saw your thread of a freeware mesh.

another stunner! 90-metre data were not doing the french and italian alps much justice--now they're something elsethanks!vilk

Thank you very much Holger and Jonathan. I have been waiting for a 38m mesh for the Alps. Only problem I have is, that I have to study for my geograhpy tests next week, so I won't be able to check out the new mesh before the end of next week :(.Christianhttp://img.photobucket.com/albums/v232/chrismo/sigsky.jpgVacation: wasted time between 2 flights!

Thanks Holger,What (if any) edits do we need to make to the fs9.cfg file to see this mesh? I recall that there was a number that one could change on one of the variables that made FS display the ground in higher mesh resolution, but I've forgotten what it is (the mind is the first to go :) ).Thanks, Bruce.

Bruce,Take a look at the readme included with the mesh--it discusses the setting which needs to be changed and the installation instructions. -John

"You might want to fix Salzburg though.... :-)"You can patch that in case Holger can't fix it right away by putting a flatten after the mesh entry in your scenery.cfg. It's not perfect, but will provide a pretty quick fix and makes the problem all but invisible unless you fly right over the spot:Flatten.0=2635,N47 44.07,E13 0.03,N47 44.07,E12 59.84,N47 44.24,E12 59.84,N47 44.24,E13 0.03-John

Hi all,thank you very much for all the kind words; I'm glad to hear that you agree that Jonathan's data offer a great improvement, especially of the main mountain peaks and ridges.Sorry about the bug near Salzburg. I'm working on a small patch file that will take care of that. I will let you know once I've uploaded it.As a freeware mesh for Europe I can recommend Yohann Baptiste's SRTM series. He used the most recent Shuttle Radar data and the best available methods to interpolate or fill the many void areas in the data. I'm glad to see that it seems that our Alps mesh files is compatible with the upcoming Ultimate Terrain Europe: http://www.simforums.com/forums/forum_post...?TID=15478&PN=1John ("enyap"), as an owner of Switzerland Professional you should delete the two files mesh_SRTM2_Alps_SwissEast_LOD10.bgl and mesh_SRTM2_Alps_SwissWest_LOD10.bgl from your installation of alpsw_fe.zip.---As you can see on Jonathan's website - http://www.viewfinderpanoramas.org/dem3.html - there are a number of other areas with highly detailed data. I'm currently working on the Himalayas and Sweden (there's a high-quality Norway freeware mesh available already; see http://forums.avsim.net/dcboard.php?az=sho...ing_type=search ). I might do the other areas as well but cannot and would not want to claim exclusive rights to these files so I encourage other freeware designers to get in contact with Jonathan (or at least credit him in the docs) and use his files for your own mesh/scenery projects. These data are a wonderful gift to the FS community!Cheers, Holger

Hi John,thanks for posting that work-around! I'm working on a small LOD11 mesh patch that will be a more permanent fix but that flatten entry is a great idea - thanks for sharing!Cheers, Holger

You're welcome.......... :)I've updated the flatten so it doesn't look like a "hole" appears in place of the World Peace Tower...Flatten.0=3100,N47 44.07,E13 0.03,N47 44.07,E12 59.94,N47 44.24,E12 59.94,N47 44.24,E13 0.03Flatten.1=2867,N47 44.07,E12 59.94,N47 44.07,E12 59.89,N47 44.24,E12 59.89,N47 44.24,E12 59.94Flatten.2=2635,N47 44.07,E12 59.89,N47 44.07,E12 59.84,N47 44.24,E12 59.84,N47 44.24,E12 59.89http://forums.avsim.net/user_files/140933.jpg

Hi all,thanks, Brad, you're welcome!I've attached below a patch file based on Jonathan's adjustments to the source data. Alternatively, it's also available at http://forums.simflight.com/posting.php?mode=reply&t=48889To install, unzip directly into the installed "mesh Alps LOD10 by Ferranti & Sandmannscenery" folder.I will upload the patch with a read-me to Avsim but would like to wait a few days in case other issues are found.Cheers, Holger

Same here, the patch does not work. The peak changes... looks like in the shot John sent and sharper when you get closer. Maybe the different LODs are doing their tricks here.Anyway, I had a bit more time to look around and this is surely the best mesh for the alps I have seen. :-)Tatu
