Surveying

Paul Corrigan and Associates (PCA) is a multi disciplinary Geo-surveying and Mapping Consultancy comprising of four sections:

Topographic Survey | Transportation Surveys | Measured Building Survey | Legal Mapping

Because of the value of land, and the need to accurately record who owns what, Land Surveying has historically been one of the first professions to be regulated in most countries.

Surveying or land surveying is the technique and science of accurately determining the terrestrial or three-dimensional space position of points and the distances and angles between them. These points are usually on the surface of the Earth, and are often used to establish land maps and boundaries for ownership or governmental purposes.

In order to accomplish their objective, surveyors use elements of geometry, engineering, trigonometry, mathematics, physics, and law.
