Spatial Data Transfer Standard, Part 7: CADD Profile
Index page for SDTS Part 7
U.S. Army Corps of Engineers
This SDTS Computer Aided Design and Drafting (CADD) Profile supports exchange of geospatial data contained within CADD systems with other geoprocessing systems. CADD software makes up a large portion of the Geographic Information Systems (GIS) marketplace. CADD software allows for several types of elements, in particular, the use of three-dimensional elements and complex curves that are not commonly used by GIS. This profile allows the representation of two- and three-dimensional geographic vector data from CADD packages to be transferred via the SDTS standard.
The Computer Aided Design and Drafting Profile (CADD) contains specifications for an SDTS profile for use with vector-based geographic data as represented in CADD software. The purpose of this profile is to facilitate the translation of this data between CADD packages without loss of data, and support the translation of this data between CADD and mainstream GIS packages.
This profile supports two-dimensional vector data and three-dimensional vector data, where the third dimension is the “height” of the object. These data may or may not have topology. This profile does not support raster data or two-dimensional transfers already represented by another profile.
