Technical note

HDF to BMP: 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. BMP 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. BMP 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

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

  • Render every file in a folder to BMP 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.

This online converter works perfectly for small batches of files. I occasionally need to convert BMP to JPG, and it doesn't make sense to install software for such simple tasks. It's much easier to just visit the site, click a couple buttons, and get the same quality result in seconds.
