Technical note

How SID and GIF differ in practice

SID carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. GIF 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 SID original if the data still has to go back into a GIS. GIF is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that SID compression already removed, and the output file will usually be considerably larger.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GIF 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

SID to GIF Conversion

What are SID files?

MrSID (Multiresolution Seamless Image Database) is a compressed raster format for high-resolution geospatial imagery. Developed by LizardTech, it uses wavelet compression to efficiently store aerial/satellite images, maps, and large documents while supporting fast zooming and geospatial data.

What are GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
