Interpreting Topographic Survey Drawings for Garden & Landscape Designers
Garden and landscape designers are increasingly recognising the value of topographic surveys.
Accurate land survey data is an essential foundation for any successful garden & landscaping project. Understanding how to interpret topographic surveys enables designers to work efficiently with the existing site conditions.
The webinar provides a clear introduction to land surveying equipment, data, capture & processing.
Through real survey examples and annotated drawings, you'll learn how to understand levels, slopes, drainage, structures, boundaries and other site information to support design development.
This session will help you build confidence in reading and using survey information to unlock its full potential.
