MapInfo MIF/MID
Open BetaMIF/MID és el format d'intercanvi basat en text de MapInfo Professional. Els parells de fitxers (.mif + .mid) contenen la geometria i els atributs respectivament. Un format universal per a l'intercanvi de dades entre sistemes SIG.
Característiques clau
Sobre el format MIF
MIF/MID is MapInfo's text interchange format: geometry and column definitions live in the .mif file, and the attribute values themselves in the .mid, line by line. The format is documented and readable in an ordinary text editor, which is why it has been used for decades as a neutral go-between for GIS: MapInfo Pro, QGIS, Global Mapper and FME read it without plugins.
In Russia MIF/MID is still found in municipal and cadastral workflows: development, boundary and road network layers are accepted and issued in it. Exporting OSM into this format saves you from digitizing the base by hand — the data arrives right away in the shape the receiving side opens natively.
The output is a ZIP archive: a pair of .mif and .mid files per layer plus a README.txt naming the coordinate system. The pairs must be kept together: without the .mid the layer opens with no attributes. Coordinates are in WGS84 (EPSG:4326) by default, and another projection can be chosen at export time. The files are built by the ogr2ogr utility in MapInfo File mode with an explicit FORMAT=MIF, and if a layer fails to convert it is honestly marked as failed — the service does not slip you a binary TAB under a .mif name.

Qui utilitza els mapes MIF
Com exportar MIF
Com obrir el fitxer després de l'exportació
- MapInfo Pro — File -> Open, file type "MapInfo Interchange (*.mif)"; the program picks up the paired .mid itself and offers to save the layer as a native TAB for further work.
- QGIS (free) — Layer -> Add Vector Layer -> pick the .mif. From there the layer can be styled and re-saved to SHP, GeoPackage or any other format.
- ogr2ogr (GDAL) — a one-off conversion without a GUI: ogr2ogr -f GPKG out.gpkg roads.mif builds the layer into a GeoPackage.
- Global Mapper or FME — if the MIF/MID has to be poured into someone else's data exchange pipeline with reprojection and field renaming.
- Before sending it to the client — unpack the whole archive: the .mif + .mid pair must sit in one folder, otherwise the attributes are lost.
