Lines on the map: records of international boundaries

The National Archives holds one of the largest and most important
accumulations of maps in the world. They document the United
Kingdom's involvement in shaping boundaries and in resolving
boundary disputes over many centuries, either as a colonial
power, neutral observer or independent source of surveying
expertise. Rose Mitchell looks at how the process has been
documented, from letters and reports to treaties, drawing on maps
and surveys which made lines across sand, snow, water, forests,
plains and mountains around the globe.


Rose Mitchell is a map curator at The National Archives. She is
co-author of Maps: their untold stories.
