Frequently Asked Questions

What is GIS?

A Geographic Information System (GIS) is a system that creates, manages, analyses, and maps all types of spatial and non-spatial data. With GIS, you can take all sorts of data that have a geographic component and visualise them on a map. For example, you can map the locations of different businesses, the distribution of natural resources, population density, or even the spread of diseases. This helps us understand patterns, relationships, and trends that might not be obvious in raw data alone.

GIS is used in many different fields, such as urban planning, environmental management, public health, transportation, emergency response, construction, mining and even marketing. By combining spatial data with other types of information, GIS allows us to make better decisions, solve complex problems, and gain valuable insights.

What is Remote Sensing?

Remote sensing is the process of gathering information about an object or area from a distance, without physically being there. It involves using various technologies and sensors to detect and measure objects, features, or phenomena on the Earth's surface or in the atmosphere.

One of the most common examples of remote sensing is satellite imagery. Satellites orbiting the Earth are equipped with sensors that can capture images and data from space. These sensors can record different types of information, such as visible light, infrared radiation, or radar signals, depending on their purpose.

What is Machine Control?

Machine control is a technology used in construction and earthmoving operations that allows heavy equipment, such as excavators, dozers, graders, and pavers, to be controlled and guided with high precision using digital models and positioning systems.

Traditionally, construction projects relied on surveyors to stake out the site and provide reference points for equipment operators to follow. This process was time-consuming, labour-intensive, and prone to human error. Machine control automates and streamlines this process, improving efficiency, accuracy, and productivity.

What is Site Engineering?

A setting out engineer is a professional who plays a crucial role in construction projects, particularly in the early stages of site preparation and layout. They are responsible for translating the architectural and engineering designs into physical reality on the construction site.

Setting out engineers typically use a variety of surveying equipment, such as total stations, levels, theodolites, and GPS systems, to accurately measure and mark positions on the site. They also rely on specialised software such as GIS and computer-aided design (CAD) programs to interpret and transfer the design data.

What are Drone Surveys?

Drone surveying is a modern technique that involves using drones or small unmanned aircraft equipped with cameras and sensors to capture aerial data and imagery for various surveying and mapping applications.

Traditional surveying methods often involve ground-based equipment and personnel physically measuring and inspecting sites, which can be time-consuming, labour-intensive, and sometimes dangerous or inaccessible. Drone surveying offers a more efficient, cost-effective, and safer alternative, particularly for large or challenging areas.

The advantages of drone surveying include faster data acquisition, improved safety by eliminating the need for personnel in hazardous areas, cost-effectiveness compared to traditional methods, and the ability to capture high-resolution data from unique perspectives.
