MapInfo Pro includes sample seamless maps or you can create your own. Some of these data files are available on the Precisely web site in the MapInfo Pro Tutorial data. We recommend you download this data for use with these examples.

From the mapinfo\tutorial\tut-usa\usa\dc\seamless directory, choose dcmetrow. A seamless map layer of water areas in Washington DC displays. Notice at first glance that the seamless layer looks like any other MapInfo Pro table. However, the Dcmetrow seamless map layer is made up of the following base tables:

  • VAARLIW.TAB (Arlington Virginia water areas)
  • VAALEXW.TAB (Alexandria Virginia water areas)
  • DCWASHW.TAB (Washington DC water areas)

To display a sample seamless map:

  1. On the HOME tab, in the File group, from the Open list, click Open.
  2. From the data directory, choose a seamless layer.

    The following is an example of a map layer of water areas in Washington DC.



The structure of each seamless layer includes the path name of each base table plus a description that defaults to the table name (alias). To view the table structure, turn the seamless layer off and display the seamless table in a Browser. Refer to Turning Seamless Layers On and Off.
