Topographical Surveys

A good topographical survey will convey the natural land and any man made features clearly and concisely. We have over 16 years experience conducting topographical surveys in accordance with The Royal Institution of Chartered Surveyors (RICS)

EOS Geomatics provides clients across London and the home counties area with dependable and reliable topographical surveying. The design process of projects involving many types of differing assets typically utilises a topographical survey. Common use cases have involved asset plans, swept path analysis, road design and layout, housing and other development purposes.

The overall purpose of this type of survey is to collect survey data about natural and man-made features of the surrounding land to then make informed decisions.

What Is a Topographical Survey?

A topographical survey is a type of survey that maps the physical features and contours of a piece of land.  Topographical surveys are typically conducted using specialised equipment such as GPS, laser scanners, and total stations to measure and record the elevation, distance, and location of various points on the land. The resulting data is used to create topographical maps and plans that can be used in a variety of applications, including urban planning, land development, construction, and engineering projects.

What can EOS Geomatics do for us?

We have extensive experience across many different aspects of land surveying. We have completed many topographic surveys and understand that a cartographically well styled plan makes all the difference. We care not only about accuracy and detail but also about presentation – after all a surveys job is to effectively communicate and convey in the clearest manner possible the layout of the land and its features.

Our primary method of conducting topographical surveys is through laser scanning, which delivers a globally consistent point cloud from which a drawing can be extracted but we also use a TS15 total station and/or a GPS receiver depending on ground conditions and detail to be picked up.

The technology used today allows for much faster data acquisition, and it does appear to have simplified the process but it’s important to use a professional surveyor because there are many things that can go wrong.  Using a surveyor that fully understands how to calibrate the equipment, how to conduct a survey to the specified accuracy and place the survey on the correct orientation is critical if the project is not to be delayed or designed on incorrect information. Even with 16 years experience we have to methodically check our work to make sure that our deliverables meet both our and our clients expectations.
