Convert MIF to KML

Understanding the MIF and KML file formats

MIF (MapInfo Interchange Format) is a geospatial vector data format used primarily by MapInfo software for storing map data, including points, lines, and polygons. It is often accompanied by a MID file containing attribute data. KML (Keyhole Markup Language) is an XML-based format developed by Google for displaying geographic data in Earth browsers like Google Earth and Google Maps. KML files can represent points, lines, polygons, and images with rich styling and metadata.

Why convert MIF to KML?

Converting MIF to KML allows you to visualize and share your geospatial data in widely used platforms such as Google Earth and Google Maps. KML is more accessible and supported by a broader range of applications compared to MIF.

Best software for MIF to KML conversion

The most reliable and widely used tool for converting MIF to KML is GDAL/OGR, an open-source geospatial data conversion library. Another user-friendly option is QGIS, a free and open-source GIS application with a graphical interface.

How to convert MIF to KML using QGIS

1. Download and install QGIS from the official website.
2. Open QGIS and go to Layer → Add Layer → Add Vector Layer to import your MIF file.
3. Once loaded, right-click the layer in the Layers panel and select Export → Save Features As....
4. In the Format dropdown, choose KML.
5. Specify the output file location and click OK to export.

Alternative: Using GDAL/OGR command line

If you prefer command-line tools, use the following command with ogr2ogr (part of GDAL):

ogr2ogr -f "KML" output.kml input.mif

This will convert your MIF file directly to KML format.

Key considerations

• Ensure your MIF file is accompanied by its MID file for attribute data.
• Check the coordinate reference system (CRS) and reproject if necessary for compatibility with KML (usually WGS84).

Summary

Converting MIF to KML is straightforward with tools like QGIS or GDAL/OGR, enabling you to share and visualize your geospatial data in popular mapping applications.
