MI Overlapping regions and gaps
Is there a product (commercial or otherwise) out there that will automatically fix/clean tables that contain multiple instances of overlapping regions and gaps between regions. Thanks Tom Orr
Re: MI v AND h COORDINATES
It's ATT's coordinate sysstem for billing LD calls. So you must either have switch locations or rate centers. Cartographic coordinate systems are not something I'm strong on, but basically it is a conversion so that you can use the Pythagorean Theorem to easily calculate distance between two points. It's good for Continental US and Southern Canada. But for Alaska, Hawaii, and I suspect N. Canada, the conversion is inaccurate. By no means is the accuracy of any location at the street level. I had planned (am planning?) on writing a MapBasic program to convert V H to Lat Long, so I have a bit of code I found on the web w.r.t. the conversion. Be happy to pass it along, but an easier solution is available. Telcordia (aka BellCore) sells a small app that converts it to Lat and Long.

Re: MI 5.5 weird error message when plotting!
Tony Shepherd wrote: Any body had any weird error messages form MapInfo 5.5 when plotting to HP DJ 750C plotters? I get an error that says: Assertion failed: file I:\Released\SHELTER\BUILD16\xvtwin\src\WPRINT.c,line 524, Using cached DC with different printer information. We occasionally get the same "assertion failed" message when trying to print to a networked printer (doesn't have to be a plotter). Sometimes the message appears when we try to print, but other times it doesn't, adding to the frustration. As with Tony, we never had this problem before, it's only started since we installed 5.5. We informed MapInfo techsupport about the problem last week, but they couldn't replicate the error, so I'm glad (in a way) that someone else is experiencing it. The main workaround that MI provided was to edit the workspace and delete the new line that contains the printer driver information. This didn't solve the problem (and it's not particularly useful, since one of the main benefits of 5.5 was to avoid the extra work involved in re-setting printer driver information). MI claims they're working on a more complete and efficient bug fix, which will be free for 5.5 users. Don't know when (or if) that will happen.

MI batch table editing
Hi, What is the best method of batch editing large numbers of identical tables? I have a couple of hundred tables to edit to apply standard line/region styles to. Their record structure is identical. They can be themed by a field called "classname" which contains a text code: lake, river, island, wetland, sandbar, etc. So a thematic map is possible, but laborious. I've tried creating a Seamless Table via the Seamless Manager tool, but it won't allow editing or creation of a thematic map on the resultant seamless table. Seamless tables are a viable solution for tables which only contain one object type (a display overide can be used for all table contents). I've tried using the "Select by Attribute" tool which selects all objects having the same attributes as the currently selected object. This is a great time saver, but it will still only work on one table, and one object type, at a time. will sum, -matt -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
Re: MI Limitations in mif-import?
Dear Claes I do not think there is a limit - and if there is it much higher than the sizes where you get the problem! We write translators to convert Ordnance Survey data into MapInfo tables. We now use MapInfos MFAL routines that are written in C and conversion is therefore very quick. However before we started using MFAL we relied on MID/MIF. The process was much slower but we imported detailed maps for large areas where the resulting files were up to 300 MB in size. I suspect a syntax error in either your MIF or your MID file. Hope this helps you.

MI MapInfo 3.x printing problem
Our organization just obtained MapInfo 3.x when our parent organization purchased ArcInfo. I installed on a computer connected to the network so we could create maps for specific areas. While the software is working fine we get a divide by zero error every time we try to print. MapInfo's web site lists this error as being an improperly installed printer. However, we have six printers installed on our network (3 lasers, 3 ink jets one of which is postscript) and we get the same error on all of them. I have even uninstalled and re-installed the printers in case the print drivers were not "installed correctly." I am still getting the same error message. All other software packages have no problem printing to any of the printers. Since the service contract for this software expired over a year ago I was hoping that someone would have some knowledge as to what specifically might be causing this problem. Thanks in advance for any help you might have on the subject.

MI Re: Chamberlin Trimetric Projection
Denise, The Chamberlin Trimetric Projection is an old thematic type of projection cooked up by the Chief Cartographer of the National Geographic Society back in the late 19th century. It looks really nice, but is a contrivance that attempts to display a map with features that are equally distanced from three separate points. Such a contrivance is impossible, but Chamberlin's attempt is a pretty good compromise. The Society still uses it, and it still looks really nice. That is a characteristic of most National Geographic Society Maps; not only are they accurate and useful, but they are actually framed and put up for display in people's homes - not just in offices. One problematic feature of this projection is that after it is drafted, color-separated and printed, the copyrighted map that is not supposed to be copied or put into digital form of any kind is downright difficult to digitize. That is, it's easy to digitize in terms of digitizer (x,y) coordinates, but the inverse computation to Latitude and Longitude is a "zinger." In the late John P. Snyder's work, "Map Projections - A Working Manual," U.S. Geological Survey Bulletin 1395, he lists it in two places in the index. The first time he covers it is in the section on pseudo conics, and specifically the ellipsoidal Bonne, the second time he mentions it in another context of contrived projections that give a hint. The old ATT projection is, according to Mr. Snyder, an ellipsoidal projection that is roughly equivalent to the Chamberlin Trimetric. Although obscure, the math for that can be scrounged from old Bell Labs reports occasionally found in various libraries. The old cartographic trick of "paneling" for changing projections with a razor blade and paste could be used with a rubber-sheet transformation, but that is using brute force rather than mathematical elegance. Another thing you could do is go to the horse's mouth. Ask the National Geographic Society and see what they have to say. I imagine they are going to ask you why you want to know the mathematical details of one of THEIR projections ... Specifically with respect to MapInfo, I have no idea how to help you.
