What is a MapInfo TAB file?
MapInfo TAB is the native format of MapInfo Pro. A table is a set of files — .tab (structure), .dat (attributes), .map (geometry) and .id (index) — that must travel together.
It remains common in telecom, insurance, retail and public-sector teams that have worked with MapInfo for years.
What is a GPX file?
GPX (GPS Exchange Format) is an open, XML-based format for GPS data. A single file can hold waypoints, routes and tracks, with coordinates in WGS84 latitude and longitude.
Almost every GPS device, sports watch and outdoor app exports GPX, which makes it the default format for sharing recorded trips. Because it is plain XML, large track logs get bulky and slow to search.
