TS ISO 710-1

TS ISO 710-1 addresses the graphical symbols used on detailed maps, plans and geological cross-sections, with emphasis on the general rules that govern how they are represented. In practical mapping and geological drawing work, symbols are the visual language that makes spatial features, boundaries and interpreted subsurface information legible and consistent across documents. This part is about the representation framework for that language, not simply a collection of isolated signs.

Why representation rules matter

In general technical practice, graphical symbols condense complex geographic or geological information into compact visual marks. On detailed maps and plans they help communicate objects, alignments, limits and land-related features; on geological cross-sections they support the reading of layered structures, dips, discontinuities and interpreted relationships below the surface. Because the meaning of a symbol depends not only on its shape but also on line style, orientation, spacing and placement, a shared set of representation rules is essential for clarity and consistency.

What this part contributes conceptually

The title’s focus on “general rules of representation” indicates a governing framework for how symbols should be presented and interpreted across related technical drawings. Such a framework helps prevent ambiguity, keeps symbol use coherent from one document to another, and supports rapid recognition by map users, surveyors and geoscience professionals. It functions as a foundation for the symbol system rather than as a field-specific application guide.

• Common visual representation principles for detailed maps, plans and geological cross-sections
• General rules aimed at making symbols legible and consistent
• A shared symbol language for cartography, geodesy and geological interpretation
• The importance of shape, linework, orientation and placement in symbol meaning
