Tile Map Service (TMS) is an Open Source Geospatial Foundation specification to manage cartographic data. TMS is similar to the other LevelRowColumn types of tile server protocols that MapInfo Pro supports, such as Google Enterprise.
A tile server is a server that contains a collection of raster tile images. The tiles cover a given place on the earth. Tiles are organized in a row/column grid fashion. There are also multiple levels of tiles. Each level represents a different resolution of data, covering the same place on the earth. The level determines the number of tiles (number of rows and columns). As you zoom in or out, the level of data may change. As you pan around, the specific tiles that are needed may change.
MapInfo Pro lets you use tile server data within the product. If you add a tile server layer to a MapInfo Pro map, then the application takes care of fetching the appropriate tiles from the server and displaying them. You only need to add the tile server layer and then pan/zoom.
MapInfo Pro supports TMS servers with either North-West or South-West origins.
MapInfo Pro has a table for tile servers that consists of a TAB file and XML file. These files contain the information necessary to communicate with a tile server and retrieve tiles correctly. This information includes server URL, coordinate system and bounds, and other parameters for retrieving the proper tiles.
You can use the TAB and XML file to view Google tiles within MapInfo Pro. Once the TAB and XML files are properly setup, you can open and use the TAB file just like any other tile server table.
After opening a tile server table in MapInfo Pro, you can add it as a layer to a map. Tile server layers act as an underlying base map, so they are added to the bottom of the layer list by default. Tile server layers do not have attribute data, so they cannot be edited and labeled. They are meant to be used as backdrop images.
