Foreword
This standard replaces GB/T 17798-1999 "geospatial data interchange format." This standard and GB/T 17798-1999 compared to primary
To change the contents as follows.
--- The standard format of the specification;
--- To the standard terms and definitions of the specification;
--- Increasing the comment section of the description;
--- Coordinate reference. to determine the coordinate reference system are defined and listed common reference ellipsoid in Appendix C, the projection type and
Projection parameters; increased elevation reference, time reference system description;
--- Geometries. an increase of point clusters, body, polymerization spatial objects; on the line, surface, annotation feature has been expanded; adds parametric
Graphics (three-point arc, circle radius arcs, elliptical arcs, cubic spline, B-spline curves, Bezier curves, three-point circle, center
The radius of a circle, oval, triangle, rectangle) deterministic description; adds support for annotation description;
--- Topology. increases the recording node topology and topology data line segment;
--- Attribute structure. According to the common database and programming language data types are specified in the description field;
--- Tense feature. Added temporal factors described in the property structure;
--- Graphical representation of data. graphic positioning information and graphics performance information separately, and a graphical representation of information description, including points,
Line, surface, annotation performance description information;
--- Increase in Appendix C Description Parameter Chinese common reference ellipsoid and its parameters, projection type and projection needed;
--- Increase in Appendix B gives the exchange format XML schema (Schema).
The Standard Appendix A, Appendix C is a normative appendix, Appendix B, Appendix D, Appendix E, Appendix F for the informative appendix.
This standard by the National Standardization Technical Committee on Geographical Information.
This standard was drafted. National Institute of Surveying and Mapping Bureau of Surveying and Mapping Standardization, State Key Laboratory of Information Engineering in Surveying, Wuhan University.
