Technical note

HDF to JPEG: what to expect from the conversion

HDF 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. JPEG 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 HDF. HDF carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JPEG 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 HDF 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 JPEG opens on any computer and any phone. reaConverter produces those from HDF in batch, entirely offline.

  • Render every file in a folder to JPEG with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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

HDF to JPEG Conversion

What are HDF files?

HDF is the most common extension of files in the Hierarchical Data Format, Release 4, a container for scientific data developed at the National Center for Supercomputing Applications and now supported by The HDF Group. It is best known from satellite remote sensing: NASA's Earth Observing System adopted it in 1993, and instruments aboard the Terra and Aqua satellites, such as MODIS and ASTER, delivered their products in this form. One file may hold many layers, for example several spectral channels, a quality mask, and the coordinates of every pixel, along with notes that explain them. The same extension is used for the HDF-EOS variant, which adds conventions for geographic location. The newer HDF5 is a different format and is normally saved with other extensions.

What are JPEG files?

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the internet.
