GPS Surveys

At Outsource CAD, we deliver high-precision GPS surveys for architects, developers, engineers, planning consultants and property owners who need fast, reliable, geo-referenced site data. Whether you’re starting a new build, extension, land purchase, boundary clarification or topographical survey, our GPS teams capture accurate coordinates and levels to inform every stage of your project.

With thousands of measured surveys completed for clients across the UK & Ireland, we provide a seamless, professional service — from data collection through to highly detailed CAD drawings and 3D models.

What Is a GPS Survey?

A GPS survey uses high-accuracy GNSS equipment to capture real-world coordinates (X, Y, Z) across a site. This allows your project to be correctly geo-referenced to OS Grid, ITM, or other survey control systems.
Our equipment records precise positional data to millimetre accuracy, giving you a reliable foundation for planning, design and construction.
