Technical note

What changes when you convert SG-GRD-Z to JXR

Every cell in an SG-GRD-Z 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. JXR 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 JXR returns a shade, not an altitude. SG-GRD-Z carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXR 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 SG-GRD-Z original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to JXR 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.

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.

FAQ

SG-GRD-Z to JXR Conversion

What are SG-GRD-Z files?

SG-GRD-Z is a compressed grid file of SAGA GIS, a free, open-source geographic information system used for terrain analysis, hydrology, soil science, and climate studies. A grid is a map made of equal cells with one value in each, such as an elevation model. The older SAGA format keeps such a grid in several separate files: one with the values, one with the description, and often one with the projection. A file with this extension packs all of them into a single archive, which is more convenient to store, copy, and send, and which takes less space because the data are compressed. The archive can be opened in SAGA GIS like an ordinary grid, without unpacking it by hand.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
