Description: | The draughtsman used Balsham Steeple and West Wickham Steeple at the top left of this plan as triangulation points. From these positions, he made angular observations with a theodolite to measure the height of the land and to plot individual topographical features. Pencil rays radiating from these two points record the measurement process. | License: | http://www.bl.uk/services/copy/permission.html | Rights holder: | British Library | Subjects: | Woodland Agriculture Plans Cartography And Topography Landscapes Marshland Maps Trade And Economics | Source: | Collect Britain | Creator: | Verron [Charles] | Identifier: | http://www.collectbritain.co.uk/personal... | Language: | en-GB | Go to resource |
