Abstract
In order to exchange a drawing data through the lifecycle in public works, a data interconversion system between Digital Mapping (DM) data and Scadec Exchange Format (SXF) data has been published in Geospatial Information Authority of Japan. With a revision of specifications for public surveying, the specification for exchanging from DM data to SXF data has been revised. However, a data interconversion system between DM data and SXF data in accordance with the current interconversion specification does not exist. It is necessary to implement the conversion from DM data used in plan phase to SXF data used in design phase, and the conversion from SXF data used in design phase to DM data used in maintenance phase. In this paper, a data interconversion specification was specified and its system was implemented. It's functions were verified using actual DM and SXF data. And, the implemented system is open to public on public survey viewer and converter of Geospatial Information Authority of Japan.
