General
The Computer Graphics Metafile provides a file format suitable for the storage and retrieval of picture information. The file format consists of a set of elements that can be used to describe pictures in a way that is compatible between systems of different architectures and devices of differing capabilities and design.
The AST profile, described in this part of ISO/IEC 12071, defines a subset of CGM elements, sets limits and generation and interpretation behaviour according to the rules for profile definition defined in ISO/IEC 8632. The AST profile defines a version 2 CGM suitable for use in advanced scientific and technical graphics, for example CAD, mapping, earth sciences.
Position within the taxonomy
AST is one of four core profiles defined within the taxonomy for CGM profiles. These are shown in Figure 1 in diagramatic form. The diagram uses the following conceptual framework to define profiles:
The four core profiles (as indicated in Figure 1) are:
| Taxonomy identifier: | Profile Name: | |
| 1 | FCG-11 | Basic Scientific and Technical graphics (BST) e.g. business presentation graphics, simple desk top publishing |
| 2 | FCG-23 | Advanced Scientific and Technical graphics (AST) e.g. CAD, mapping, earth sciences |
| 3 | FCG-32 | Basic Presentation and Visualization — the Model Profile from the CGM standard, e.g. graphics arts, high end desk top publishing |
| 4 | FCG-33 | Advanced Presentation and Visualization (APV) e.g. imaging, scientific visualization. |
This part of ISO/IEC ISP 12071 defines the AST profile.
User requirements and scenario
This part of ISO/IEC ISP 12071 provides a profile, AST, which is suitable for advanced scientific and technical graphics, for example CAD, mapping, earth sciences.
