Technical note

What changes when you convert GXF to JP2

Every cell in a GXF file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. JP2 stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the JP2 returns a shade, not an altitude. GXF carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JP2 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 GXF original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as JP2 opens on any computer and any phone. reaConverter produces those from GXF in batch, entirely offline.

  • Render every file in a folder to JP2 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

GXF to JP2 Conversion

What are GXF files?

GXF (Grid eXchange File) is an open text format for exchanging gridded data between different programs. It was developed by Geosoft, a Canadian company that makes software for geophysics, and it became the standard way of passing gravity and magnetic survey maps between systems. Such a map is a net of equal cells, and each cell holds a measured value, for example the strength of the Earth's magnetic field. A GXF file stores these values as plain text, together with the information needed to place the grid on the ground, such as the spacing between points and the map projection. Because the file can be opened in any text editor and does not depend on the software that made it, it is also used to share elevation data and other kinds of surfaces.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
