ortho-imagery

Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".

I think it might be unlikely that Jasper by itself is any different than running it through IM. Try OpenJPEG.

Ah, I can't access that. Dropbox is a pain with sharing. The file has to be in the public folder and to share it you have to right click on the file and click copy public link. I'll give OpenJPEG a try next time I'm at work, thanks.

Yeah that did it, thanks. Yeah that works. Hopefully I can replicate that.

Just curious. What is your objective with the tiles? Do you know that you can create tiled tiffs or pyramid tiled tiffs with IM? I do not know if either will help. The simple tiled tiffs have each tile as a layer or page in the one output tiff. That way you keep them all together and access them with imagename.tiff[x] where x is the tile number 0....N

I'm developing for the flight simulator X-Plane 10. I'm adding higher quality ortho-imagery and I need it in 2048x2048 tiles to overlay on top of USGS provided grid float NED files. The simulator doesn't support pyramid files currently, or from what I understand.

Very interesting. Many years ago (in the late 1980s), while working at TRW, I was involved in creating a large database for a Honeywell flight simulator. We took aircraft imagery and orthorectified it and mosiaced all the images together into on large orthomosaic. Then for the flight simulator we generated sequences of perspective oblique images that the simulator blended together in transition as the the "aircraft" flew.

Oh cool. I'm hoping that the imagery converted with this looks good. Currently the auto generated imagery does not look great at all.
