Land Surveying is the measurement and mapping of our surrounding environment using mathematics: chiefly geometry, trigonometry, regression analysis; physics; engineering; metrology, and programming languages.
Transportation Design is the geometric design of roads that aims at optimizing efficiency and safety of people and goods on the move; minimizing the transportation cost and damage to the environment, and enhancing 'livability'. It involves the design of ingress and egress of vehicles, study of traffic volumes and capacity analysis.
Land surveyors and transportation designers work mostly for government departments and infrastructure companies. However, as surveying and road design is an integral part of any construction work, they are employed in construction firms where they act as consultants to civil engineers.
With CAD software, surveyors can streamline projects and evaluate multiple what-if scenarios. They can more easily weigh environmental constraints, aesthetic concerns, and construction costs. CAD helps surveyors to enrich the design process using visualization and simulation tools that give the stakeholders a better understanding of a site. In short, they can quickly and easily create, annotate, move, rotate and plot and generate land surveying drawings.
In transportation design, CAD is used to evaluate existing conditions of transportation infrastructure and generate data-rich proposals, design, and document.
