mapinfo - What is a seamless table?


A client has asked me to provide a dataset in seamless table format. Could anybody describe to me what a seamless table is?

I understand that it is a format used by mapinfo, but can I create a seamless table in some other way, by FME for example?
Thanks.



Answer



A seamless table is an index table referencing other MapInfo tables (raster and/or vector) thru these tables MBR, Minimum Bounding Rectangle.


If you open a seamless table into a map window in MapInfo Professional you will not see the data from the table itself, but MapInfo Professional will open the tables which MBR is inside the current view of the map.


The seamless table holds only very litte data itself: a column holding path and file name of the table and a spatial object illustrating the MBR of the data in the table


In the Tool Manager of MapInfo Professional you'll find a tool called Seamless Manager. This tool will help you create a Seamless table.
