    I have a client who needs a high-res map of colonial Washington D.C. The link they sent me has the map in .sid format which is some proprietary format created by lizardtech for zooming in on maps without having to have a T1 connection or anything. Does anyone know if it's possible to translate that to a format acceptable to Photoshop? When I tried just opening it, it was treated as a RAW file and asked me to plug in the size information, but it never worked very well for me.

    Anyone have any experience with this??

    Our GIS person at work uses TNTmips. Version 7.00 and higher contain support for MrSID on Mac OS X. TNTmips is quite expensive.

    TNTlite is the same thing, but limited in the size of the file (geographical area) that it can work with. It's free (no charge). It's probably what you need.

    GIS software like TNTmips is not something you can 'figure out'. That's why people get Master's degrees in GIS. TNT is extensively documented in PDFs from their site, so if you're able to learn highly complex software from reading manuals, you'll have lots of resources.

    This is serious, hard-core unix software. It runs in X11 on OS X, Linux, Solaris, and MS Windows. You can do really awesome stuff with it, but it's not like anything you've probably used before.

    Read this release notes page to get started:

    Thanks for the advice. I am but a lowly graphic designer, so I may have trouble figuring this out, as you said, but you've pointed me in the right direction. Trouble with clients is, they think if they can find it on the web, it can be printed on the dust jacket of their book, no problem. I run into this a lot, but I"ve never seen this kind of file. Really amazing stuff!!

    The file is known as a Mr. Sid file.

    They are really quite neat. There used to be a photoshop plugin that would let you open the file directly in photoshop. I have a quark XTension that will let you import the file into quark. You can than save a PDF of the document and then open the PDF in photoshop and save as any file you want. You might be able to find the XTension on the Lizardtech website. Oh one caveat you need to have a version of quark prior to 6. So you need 5 or 4. If it will help you and you can't find it PM me.

    In addition, if it is a SID file and a map of DC. It most likely came from the library of congress american memory website. It is one of favorite websites. Most of the stuff there belongs to you and I. They have copy-write information available. Most of it is public domain.

    If you supply me with the url or even the file I can convert it to a psd, tiff, or jpeg. Let me know what you need and I'll hook you up. :)

    .sid files

    I am using MrSid plug in and ExpressView. They may be still available free at the developer, ExpressView can View and export sid files.

    AFAIK ExpressView depends upon Rosetta to operate, so it will work with OS 10.6 and earlier.

    Another option is GraphicConverter X using their mrSID plugin.
