Nokia Landmark Exchange (.lmx)

Nokia Landmark Exchange (.lmx) is Nokia's XML format for points of interest — named, described locations with coordinates that the Landmarks feature on Symbian S60 phones could store and show on a map.

At a glance

History

LMX is an XML schema (namespace http://www.nokia.com/schemas/location/landmarks/1/0) that shipped with the Location/Landmarks application on Nokia's Symbian S60 phones. No public introduction date for the format itself is documented; S60 3rd Edition, the platform generation where GPS and Landmarks became common, launched in 2005.

Where it is used

LMX files were imported into a phone's on-device landmark store by Nokia's own Location application, then shown on a map by whichever mapping app was installed — Nokia Maps and its Ovi Maps successor, or Google Maps Mobile. GPSBabel documents real-world compatibility testing against Nokia's N82 and N95 handsets.

Structure

An LMX file is XML wrapping a landmarkCollection of landmark entries, each with a name, description, coordinates (latitude, longitude, altitude) and optional address fields. GPSBabel also documents a compressed WBXML binary variant, but notes most Nokia phones of the era could only read the plain XML form.

How widespread

Tied to Nokia's Symbian S60 phones, a platform Nokia stopped selling phones on after its 2014 sale of the Devices & Services business to Microsoft. Files in this format today come from archived exports of those older devices.

RouteConverter support

RouteConverter reads and writes LMX with its own parser (JAXB-based XML binding), not through GPSBabel — it always writes the plain XML variant, never the WBXML binary form GPSBabel optionally supports.
