Hi, I am using DRGs in TIFF format and using BExtractor to extract the building locations. But Bextractor is failing to load the geo-referenced TIFF. I tried...
Hi Paresh, ... Normal USGS DRGs have a single band. They are 8-bit TIF files with indexed color (palette). So, your DRGs may be a bit unusual, or perhaps...
Hi Ben, ... Well, you are right the DRGs we have are not from USGS, but they are from some other source. ... Exactly, I looked into the BExtractor code and...
... What is that source? I ask because the file is quite non-standard.. ... That's because your image isn't RGB. Nor, for that matter, is it a DRG. Your...
Ben, ... Well, I am working on at FL. Intl. University and we here have a department called International Hurricane and Research Center (IHRC). It is IHRC...
... Ah, OK. But, just to be clear, they are not DRGs. They are normal aerial images. "DRG" is the USGS's name for their scanned topographic maps. ... Yes -...
Ben, Thanks, I will get back to the source of the aerial image and get it fixed. ... Paresh Gupta Research Assistant Distributed Multimedia Informations...

For Babbages sake.. can somebody correct my math for me I keep getting this wrong. I want to compute a matrix that will transform a set of points in a plane (a...
Hi Everybody. Could you do me a favor? Now my master paper is to create the 3D terrain scene by RS data or aviation photo. Then do some interaction design on...
Hi Haifeng, ... This sounds like an excellent addition to Enviro. ... Yes, certainly. Look at the vtRoadMap and vtRoadMap3d classes, especially the way they...
Hi Ben Thanks for your reply ... It heard very well and make me excited! So what I worry about is the problem of the efficiency. I know many arithmetic for...
... For roads: to some degree, yes. Consider that CLOD is generally for the terrain surface itself, not for "culture" on the terrain such as roads. The VTP...
Hi Ben-- Well the visualization intern has arrived. He is sort of Maya-centric but you should have seen his eyes glow when I showed him VTP! Our preliminary...

... I've found that too. Most of the schools are teaching that 3D=Maya, and it's sort of the situation where if all you have is a hammer, everything looks like...
... Tell me about it. About a year ago myself and a number of others were invited along to a set of discussions with the planners for The Art Institute, who...
There is a large amount of SRTM data which was 'cleaned' by Jean-Marc Paguet, for Africa and Eurasia. Jean-Marc applied an algorithm which interpolates the...
This is great news. I downloaded one of these files to test but my VTBuilder refuses to import from these files. What could I be doing wrong? I am using the...

Dave, Could you email me (directly) to explain exactly what VTBuilder does when you try to import the .hgt.zip, and include the 'debug.txt' that it generates...
Any chance I can get the software to clean up the Asia SRTM. Of course I'd send it to anyone who wants it (I could put it up somewhere at least temporarily...
Brian, Did you browse the page on the VTP site, link in the email responded to below? You can see how to get several tools for cleaning up SRTM. As for...
... Yes, it looks like the VNS/WCS-provided srtmfill tool produces the best results. I'm just wary of starting what would be a very long batch job without...
Hi Brian-- ASTER will be coming online at our place in the very near future. If it is the DTM you are interested in, that would be different (there are also...

Thanks Ben, we are mostly interested in the DTM, but we would also love to have the scenes as well. As far as issues related to the DTM, I am honestly...
Brain-- You may want to look into the time differential between acquisition of band 3n and band 3b. This can lead to artifacts in the DTM. --Ben University of...

Hi, I just wanted to know if occlusion culling is implemented in vtosg. If yes, is it implemented for the terrain, culture, and so on. Thanks! -Paresh ... ...
Hey folks-- I just created a swanky new SRTM mosaic of dimensions 18145 x 643 (it's a swath for a flythrough). Enviro keeps telling me "The elevation grid...
