I am using gdal_translate convert USGS DEM data to geotiff ,and generate .ive file with a geotiff texture via osgdem.But I see a flat terrain with the texture...
Hi Lluís, I spent some time looking at your building data. For the most part, it is slow simply because it is very detailed, hence a high polygon count. For...
... Neke, You might want to ask on the GDAL or OSG mailing lists. The VTP reads USGS DEM directly, so it has no need of gdal_translate to do that. We also...
Hi folks, NASA has release a new version of SRTM, version 2, which has the water area flattened to solve the noise problem. The voids (gaps) remain. ...
... I think tiles much smaller than a single country tile would be friendly to most peoples download limits and allows us to pick local areas of interest. ...

... Would you propose some tile size larger than 1x1 degree, but smaller than a country? How large would this 'local area of interest' be? The user might ...
Quite frankly, Ben, I do not see the need to redistribute the data in any form, appreciated though your efforts are, as always! The 1 degreee tiles are between...
Davide, From the correspondence i've received, tile per country is definitely a popular choice. Leaving smaller countries inside the tiles for larger ...
In my experience, far better compression ratios can be achieved with software like WinRar or 7-Zip than using standard ZIP/GZIP files. Both support multiple...
The CGIAR site has a good interface but the download speeds I'm getting are about 3 k/sec and I have a T-1. Torrent files would make this go a lot faster! ... ...
... Yep. No rocket science in SRTMFill. ;) ... -- Chris 'Xenon' Hanson aka Eric Hammil | http://www.3DNature.com/ eric at logrus "I set the wheels in motion,...
I agree :). Nice idea but a slow server makes CGIAR almost unusable for large datasets. The interface design remains a strong point. That kind of options, plus...
... software like WinRar or 7-Zip than using standard ZIP/GZIP files. Both support multiple operating systems. WinRar has an easier to use interface but 7-zip...
... This is very true. One solution i found is bzip2 (http://www.bzip.org/). It is roughly as good as Rar or 7zip, and it is available a small, fast, easy to...
Davide, thanks for telling us about WinImp (its quite fast and efficient and offers a good GUI). I did a little analysis below comparing several major...
... I'm getting around 12 K/s from CGIAR today, which is unfortunate; from NASA's servers i get SRTM at 400 K/s. I see that CGIAR has arranged gap-filled SRTM...
... Here's my testing results expanded a bit with winimp. Interestingly, winimp's algorithm "1" is the default, but it's not good for this SRTM data, whereas...
David R., thanks for the detailed interesting testing results. They agree quite well with my own tests. ... I presume this is an Arc Binary Grid, not Ascii...
Ben, I was happy I could contribute. Yes, I used a binary Arc grid. Today I tested 7-zip's ability to create '.bz2' files (I didn't notice at first 7-Zip could...
... Wow! It seems Winimp is the best of them! When I wrote about the algorithm for text, I was talking about algorithm 2. You can change the default algorithm...
Hello, I downloaded all the files for Italy, I filled the gaps and I compressed them with Winimp algorithm 2. The result is: 84 uncompressed .hgt files:...

Ben, sorry to hear about your trouble. I had a similar issue before and I then I became a "backupaholic." I would suggesting using an external USB backup drive...
Not that this is quite on topic, especially for my first post to the list, but here's a second vote for hard drive mirroring as backup method, especially when...
