Digital Map Data Format (DMDF) Reader

Licensing options for this format begin with FME Desktop Professional Edition.

The Digital Map Data Format (DMDF) Reader module allows FME to read DMDF files. DMDF files are in ASCII format.


The DMDF allows transmission of digital map data in a format that is hardware independent, and holds the minimum amount of information needed to convert the data to graphics files.

Reader Overview

Features in this format are divided into four basic types: points, curves, line strings, and annotation. Every feature has an alphanumeric code (derived from the CCSM National Standards for the Exchange of Digital Topographic Data), and contains information concerning the location, rotation, text sizes, scale factors and angles.

Curves and annotation are not currently used in DMDF files.
