Understand the science behind mapmaking and surveying with a classic topography text
This volume explains the theory and practice of trigonometrical surveying, including how to connect distant points with careful angle measurements, bases, and map nets. It also features a translated section on barometric methods for measuring altitude, with practical tables and demonstrations.
This edition gathers two substantial parts: first, the geometry and instruments used to chart land, and second, portable barometrical tables that help determine level differences. It presents the essential methods, historical context, and practical steps needed for military, civil, and scientific surveying, all adapted for English instruments and divisions.
- Learn how triangulation forms a reliable map net, with guidance on instrument use, corrections, and base measurement
- Explore the repeating circle and other tools, including explanations of angle reductions and horizon distances
- Understand barometrical methods for altitude work, with step-by-step demonstrations and ready-to-use tables
- See how to translate complex trigonometric and geographic concepts into accessible, actionable procedures
Ideal for readers of historical surveying methods, cartography, and applied geography who want a clear, practical reference. This edition is well suited for students, professionals, and map enthusiasts seeking a grounded introduction to topographic science.
