A MAPINFO_MapCatalog is a server table that stores information about spatial data types and columns in a database management system. The MapCatalog contains a row for each table in a database. Multiple databases can be represented in the MAPINFO_MapCatalog.

Spectrumâ„¢ Technology Platform does not require the use of a MAPINFO_MapCatalog, but other MapInfo-based products do. If there is no MAPINFO_MapCatalog for the database, Spectrumâ„¢ Technology Platform derives the data types from the data source itself.
