Markspot

Markspot is a term used in different technical contexts to denote a fixed marker or reference location used for alignment, measurement, or annotation. Because it is not standardized, its exact meaning depends on the field.

In surveying and cartography, a markspot designates a specific reference point on a map or field, serving as a control point in geodetic networks or as a benchmark for accuracy checks. Markspots may be physical markers such as brass disks or concrete pillars, or purely geospatial coordinates in a GIS.

In digital workflows, markspot can refer to an annotation marker or placeholder within documents, images, or layouts. Reviewers place markspots to indicate issues, changes, or focal points, often accompanied by metadata like comments or IDs.

Some organizations have adopted markspot as a product or service name for tools that manage markers and annotations; in other contexts it remains a generic term used by professionals. See also markers, benchmarks, control points, and annotations.
