There are a variety of attributes that could be extracted with SQD vector data; however, there is only one Attribute field per structure in the PCIDSK vector segment. Currently the GeoGateway library extracts the value of the SQD ENUM field as the attribute, and ignores the STU, EB, NAM, PKZ, and PNR fields. On export, all fields except the ENUM are initialized to a legal value.
Due to the loss of much of the attribute and structural information, it is generally not practical to import SQD files into EASI/PACE and then export them to SICAD again after performing some operations.
SICAD georeferencing information is lost when importing SICAD files, and a units string of METRE is assumed.
Export of Siemens SICAD files is supported. These files are exported with a type of "SQD".
Only one vector layer may be exported to an SQD file. The georeferencing units will be placed in comments at the beginning of the SQD file, but will be ignored by SICAD.
