MapInfo handles heavy database queries and spatial topology better than Google Earth.
KML allows custom data via <ExtendedData> or <Schema> tags, as well as built-in fields like name and description . The converter must create new TAB columns for these attributes. HTML content in the KML <description> tag is often stripped down to plain text or saved as a single text field. convert kmz to tab file
On the professional side, the format is a native format for Precisely’s MapInfo Professional. Unlike the single-file KMZ, a TAB file is actually a multi-file set (typically including .TAB, .DAT, .ID, .MAP, and .IND). The TAB file itself is a text file describing the data structure (e.g., point, line, polygon, text). The .DAT and .ID files store attribute and spatial index data, while the .MAP holds the actual geometry. This multi-file structure enables fast spatial queries, robust attribute handling, and advanced cartography. TAB files are designed for analysis —buffer zones, overlays, SQL queries, and thematic mapping. MapInfo handles heavy database queries and spatial topology
For organizations that perform high-volume, complex geospatial data translation, FME (Feature Manipulation Engine) is the gold standard. HTML content in the KML <description> tag is
