Technical note

How HDF4 and PCX differ in practice

HDF4 is a container for scientific arrays, not a picture. One file usually holds several variables, such as temperature, pressure or wind, often across a series of time steps and a stack of vertical levels, each stored as floating-point values in its own units. PCX holds one flat image, so the conversion has to reduce all of that to a single slice and map its values onto shades. Treat the result as a snapshot for a report or a slide: the data itself stays in the HDF4. PCX stores a limited palette rather than full colour, so the conversion has to reduce the number of distinct colours. Photographic content shows this as banding, while flat graphics and icons usually survive it untouched.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see HDF4 data has GIS software. reaConverter renders it to PCX for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to PCX 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.
