Technical note

MIF to CAL: what to expect from the conversion

MIF coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. CAL is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the MIF original if anything downstream needs to query or reproject the features. MIF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the CAL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to CAL 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.

FAQ

MIF to CAL Conversion

What are MIF files?

MIF is the file with the shapes in MapInfo's interchange format, which stores map data as a pair of text files. In the .mif file are the points, lines, and areas of a map layer, written as readable text with their coordinates, colors, and line styles, while the attributes of these objects, such as names and numbers, are kept in the partner .mid file. MapInfo is a desktop GIS program widely used in business, telecommunications, and local government, and the MIF and MID pair is its open way of passing data to and from other programs, since it can be read and edited in any text editor. A MIF file needs its MID file with the same name to be complete.

What are CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
