What is MapInfo?
MapInfo datasets are vector exchange formats tied to the MapInfo Pro ecosystem and are still common in business mapping, utilities, and long-running desktop GIS environments.
In practice, MapInfo workflows usually revolve around TAB-based datasets or MIF/MID pairs, often with sidecar files that together describe geometry, attributes, and table structure.
The format remains important where organizations have established MapInfo tooling, but many cross-platform teams convert it into more neutral or web-friendly outputs for wider distribution.
