I'm working on a street mapping project where I'm lucky enough to have DOQQs from last year, so I'd like to put them as backgrounds in Illustrator so I can use them as reference to draw buildings, parks, etc. There are about two dozen DOQQs, and my PC doesn't seem up to the task of exporting them into a JPEG. There's some rotation, overlap, and reprojection issues that make it time-consuming to just place the raw DOQQs directly into Illustrator. So I'm looking for someone with a powerful ArcGIS setup. I'd send you the DOQQs and a MXD file (and a little money), and you'd send me back a huge JPEG that I could chop into a dozen tiles, and then place the tiles (by eye) in Illustrator.

Hello, there is a script here (in PHP) that slices a big GeoTiff into smaller tiles, using the GDAL tools :

GDAL can convert raster formats too.

GDAL can convert raster formats too.

It can:

gdal_translate -of JPG infile.sid outfile.jpg -co WORLDFILE=YES

will convert a MrSid file to a JPG. It's nippy too. Speak nicely to Hans and he might put this into a batch file that will convert a directory full of SIDs :rolleyes: .

Added later: Oops! should have been:

gdal_translate -of JPEG infile.sid outfile.jpg -co WORLDFILE=YES


Regards, N.
