Scope and Content

These albums record, in photographs or line drawings, the positions of minor control points (corners of buildings, tops of fence posts, etc.) used in a now obsolete method of mapping built-up areas. They were compiled between 1945 and the early 1960s. Each album contains the details of control points in a single National Grid map square (one square kilometre). As a whole, they cover built-up areas throughout England, Scotland and Wales.

Where drawn, the information consists of street plans indicating control points; where photographed, a small photograph showing the control point indicated by an arrow with a reference board is shown. In either case, topographical details placing the control points in their settings appear and it is thought that this information may be of value to local historians.
