Re: [MI-L] MI-L Tool for Batch Opening Large Amount of Tab Files

Hi John   This is not the best way to cope with Landline, or any other large dataset. With both CAD and GIS systems it is best to have all similar objects such as roads on one single layer, all buildings on another single layer etc etc.   Thus your dataset could reduce to the 63 layers that Landline contains or less if you want to combine some features like vegetation to a single layer. Most translators for Landline data and its replacement MasterMap would translate the data this way including our MapNTF and MapGML products. As you must have licensing to use this data you will presumably have access to the original NTF data. There is an evaluation copy of MapNTF on our website.   By combining objects in such a fashion you can easily turn on and off visibility of a single set of features. You can also carry out text searches on the text layers. Further performance will be vastly better as only data that hits the screen will be read whereas the approach you are trying will need to open every file. Windows itself has a limit to how may files cab be opened at one time, and bear in mind MapInfo layers are made up of four files, and if indexed five files.     Regards     Bob wwww.MapsByDesign.co.uk   ----- Original Message ----- From: John Nott To: MapInfo-L@lists.directionsmag.com Sent: Tuesday, April 04, 2006 9:04 AM Subject: [MI-L] MI-L Tool for Batch Opening Large Amount of Tab Files Hello Listers,   I have a massive amount of tab files (from a landline dataset). Which I would like to open to create a base map. However when I highlight all the files to open on the current map, MapInfo does nothing. If I select say 100 of the files to open, then they will open fine but as there are thousands it would take along time to open them this way.   Has anyone come across this problem before? Are there any tools that will systematically open a folder full of tab files until they are all open?   Any help would as always be very much appreciated.   Thanks a million!   - John         _______________________________________________ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
