Technical note

What changes when you convert NSF to JXL

NSF carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXL has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the NSF original if the data still has to go back into a GIS. NSF stores pixels without compression loss and JXL does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see NSF data has GIS software. reaConverter renders it to JXL for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to JXL with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

NSF to JXL Conversion

What are NSF files?

NSF is an extension used for files of the NATO Secondary Imagery Format (NSIF), which is the alliance's version of the American National Imagery Transmission Format. NATO armed forces and their partners need to exchange images from satellites, aircraft, and reconnaissance systems in a way that every member's equipment can read, and NSIF was created for this purpose, as the standard STANAG 4545. A file of this type is a package that holds one or several images together with graphics, text, and the information that describes them, for instance the sensor, the time, and the security classification. In practice, NSIF version 1.0 is almost identical to NITF 2.1, so the two formats are largely interchangeable, and many programs read both.
