Joe: Sorry, I was out of the office on Friday. The recent bout I had figuring out some problems with our very specialized Michigan GeoRef projection probably applies to you. Part of my problem was the data in the western end of Michigan was being "squished " into a vertical line. Sound familiar?? Most of it isn't relevant, but if you want the blow by blow, check the archives using MichGeoRef as a keyword.
All TAB files have bounds, either from Bounds statements in the Projection Info of each TAB file, or by default (which are usually huge). I'm guessing MapInfo is applying inappropriate bounds to your files. Two things that may be of use to you: 1) download a MBX called "CoordSys Bounds Manager". It allows you to directly look at, not only the bounds (and allows you to draw the bounds), but the Projection Info in any TAB file. And has some editing/modifying tools. 2) Export the problem TAB file as a MIF. Open it in a word processor, MSWord works quite well with this kind of TXT file. You'll probably find the Projection info is not exactly what you expected, or not. Not to worry. MapInfo using projection algorithms that puts different projections into "groups" that, on a practical level, map things to the same positions, then, inserts into the TAB whichever of that "group's" projection info that is most convenient for MapInfo to grab and use from their long, extensive list of projections. To solve your problem: while looking at the MIF in the wordprocessor replace ALL the projection info with your Idaho projection info, AND add Bounds that are appropriate for Idaho. Then Save, and re-import it to MapInfo. You may have to experiment a bit to get the bounds part of the statement right. This may very well work for you, assuming there aren't other problems. I'm no expert on this but I'll share whatever of my recent, frustrating and time-consuming experience is relevant to you. Feel free to contact me if you'd like more detail. ...good luck ....Bob Robert Karr Phone: 517-373-3028 GIS Operator FAX: 517-373-0171 Science and Technology Division Legislative Service Bureau Michigan State Legislature 124 West Allegan Street, 4th Floor pob 30036 Lansing, MI 48909-7536 USA --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 5848
