FAQ
CT1 to MIF Conversion
What are CT1 files?
CT1 is a raster image file extension used for CALS Type 1 files, defined by the U.S. Department of Defense Computer-aided Acquisition and Logistic Support (CALS) initiative in the MIL-R-28002 specification, and later incorporated into MIL-STD-1840 for the exchange of technical documentation. A file of this type contains a single black-and-white page, stored as a bilevel image compressed with the CCITT Group 4 (ITU-T T.6) method, which made it well suited to scanned engineering drawings, manuals, and archival paper documents. The page is preceded by a fixed-length text header that identifies the source document, the figure, the document class, the pixel dimensions, the page orientation, and the scanning density. The format supports no color or grayscale, and remains in use in legacy technical document archives.
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.
