The nma file extension identifies GPS log data associated with GPSBabel, a GPS and GIS data conversion program.
An nma file stores recorded GPS log data for use in GPSBabel. GPSBabel is available for Microsoft Windows, Apple macOS and Linux/Unix systems.
Use GPSBabel to open or import an NMA file. In GPSBabel, select the NMA format as the input format and choose the file.
GPSBabel is available for Microsoft Windows, Apple macOS and Linux/Unix.
GPSBabel can convert NMA GPS log data to another GPS format. Select NMA as the input format, choose an output format such as GPX or KML, and run the conversion.
The information retained depends on the capabilities of the selected output format.

Record marked as obsolete and not updated for a long time.
The nma file extension was used by the Nordic Optical Telescope for normalised extinction-corrected differential photometry data. Such data records photometric measurements adjusted for atmospheric extinction and compared differentially with reference measurements.
The format is obsolete, and information about the software that originally created or processed these files is no longer readily available. The file may contain tabular observational data, but its exact structure cannot be established reliably from the extension alone.
There is no known current program with reliable support for this obsolete format. If the file is stored as plain text, it may be possible to inspect it with a text editor or import it into a spreadsheet or scientific data-analysis program, although the column meanings may not be recognised automatically.
For the most accurate interpretation, documentation from the observation project that produced the file should be consulted.
No dedicated converter for this obsolete format is known. If the file contains readable tabular text, its values can be copied or imported into another data-analysis program and saved in a current format such as CSV.
Conversion without the original documentation may lose the meaning of columns or calibration information, so the source project's documentation should be retained.
