FAQ
ARC to CAL Conversion
What are ARC files?
ARC is the file of line features in the vector format of MiraMon, a geographic information system and remote sensing program developed in Catalonia by Xavier Pons. In this format, each line on a map, such as a road, a river, a contour line, or a boundary, is stored as an arc, which is a chain of points joined by straight segments. The coordinates are kept in the .arc file itself, while the attributes of the lines, such as names and codes, are kept in a database table in the DBF format, and a text file with the .rel extension describes the whole layer. An arc layer is always accompanied by a file of nodes, the points where arcs begin, end, or meet, and the polygons of MiraMon are built from these arcs.
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.
