TS 1663

TS 1663 is a standard for stating sheet sizes and the related marginal information used on maps and plans at scales of 1:2500 and larger. In map production, the sheet format and the information placed around the border are part of the drawing’s identification and usability, especially when multiple sheets must be read together as a consistent set.

Why sheet format and marginal data matter

In general technical practice, map sheet dimensions determine the physical layout of the drawing, while marginal data support identification, orientation, and linkage to adjoining sheets. Such information commonly includes sheet number, scale reference, north indication, coordinate references, borders, and descriptive fields. On large-scale maps, where detail is dense, a disciplined border layout helps users interpret the sheet quickly and compare it with neighbouring sheets in the same series.

What this standard addresses

The scope of the standard is limited to the rules for specifying sheet sizes and the associated marginal information on maps and plans at 1:2500 and larger scales. It does not concern the measurement process itself or the numerical accuracy of map content; instead, it focuses on the formal presentation of the drawing. That distinction is important because large-scale cartography relies on consistent sheet boundaries and border data to preserve readability and series consistency.

• Applies to maps and plans at 1:2500 and larger scales.
• Focuses on how sheet dimensions are stated.
• Covers the presentation of marginal information.
• Deals with drawing layout rather than map content accuracy.
