What is SDTS?
SDTS is the acronym for the Spatial Data Transfer Standard. SDTS is a FIPS(173) and FGDC (STD-002) standard that defines a non-proprietary format for packaging vector or raster spatial data with attributes, metadata, a data quality report and usually a data dictionary. SDTS is primarily intended to be used for spatial data product distribution and archiving. The format and structure of a SDTS file set is designed to enable blind transfer of information between different hardware/software environments without loss of contextual information.
