Map Data Workflow

Bring files into a GIS

Need STP content inside a GIS project? reaConverter converts it to MIF offline and in batch, so a whole folder arrives in the format your GIS expects. Placing it on the map is then a job for the GIS.

  • Convert a whole folder to MIF in one pass
  • Apply the same settings to every file in the batch
  • 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

STP to MIF Conversion

What are STP files?

STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.

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.
