SDTS
SDTS Philosophy
• Self-documenting
• Complete - containing everything needed to enable informed use
• Includes metadata (reference system, data dictionary, data quality information, etc.)
• Information for software and users to read
• Abstract model based Implementation
• Modular

Model Levels
• Conceptual [defns]– The philosophy, ideas, concepts and
definitions that form the basis and set the perspective
• Logical [modules]– give substantive shape to the ideas from the
conceptual layer
• Format [files]– Using the structures to build the end
product: “a set of files for data transfer”

Content
What is the content of a transfer?
• Features & Spatial Objects– Vector: point, node, chain, polygon, string,
arc, link
– Raster: grid, pixel
• Attributes– user-defined
– standard list

SDTS Role
• SDTS is especially suited for–Blind exchange
–Archive
• the information content requirements necessitate –self-contained and
–self-describing datasets.

SDTS
Setting Revision Scope
1. Action item to INCITS L1 membership: Review SDTS to identify recent work that has been done that would affect the rewrite of the document, i.e., better/newer concepts, and technologies identified in more recent standards.
2. Select target constructs to which to map current SDTS constructs.
3. Select target enhancements (e.g. enhanced semantic modeling).

Candidate Mappings
• SDTS Constructs map to targets
–Abstract (Conceptual) Model» bring into alignment w/ ISO TC 211
19100 suite of standards
– Implementation» bring into alignment with ISO TC 211 &
OGC specifications • Logical
• Encoding

SDTS
Implementation - Encodings
• Current SDTS encoding: – ISO 8211, Data Descriptive File
• Replace ISO 8211 encoding with – XML, specifically GML (Geography Markup Language,
OGC and ISO 19136 specification), and
– ISO 19115 metadata encodings.
• Replace Graphic Symbology with OGC Style Layer Descriptors?
