DDF file extension - SDTS topological vector profile
What is ddf file? How to open ddf files?
File type specification:
The DDF file extension is associated with the SDTS topological vector profile format.
The TVP ( topological vector profile) is endorsed by FGDC as FGDC-STD 002.4. It is the first completed and NIST approved profile and is included as Part 4 of the SDTS.
The TVP was developed to support geographic vector data with geometry and topology. It includes the SDTS defined spatial objects representing vector data with full topology that comprise a two-dimensional manifold. Data sets may contain point, line, polygon, and composite features.
The TVP accommodates USGS vector products such as the Digital Line Graph (DLG) data. The Bureau of the Census will also be using the TVP to distribute its Topologically Integrated Geographic Encoding and Referencing (TIGER) data files.
