TECHNOLOGY PRACTICE

Translating thoughts into actions is where technology plays its role. As the explorations in space and time evolve, so is the technological transformation catapulted to the next level of innovation and application development. Acquiring, processing and utilisation of spatial information is what primarily defines and decides the course of geospatial journey. This section will delve into detail the various verticals of geospatial ecosystem.

Remote Sensing

Remote sensing is the process of gathering information about an object using tools that are not in direct contact with that object. The most familiar example of remote sensing in our day-to-day life is our eyesight.

Geographical Information System

Geographic Information Systems (GIS) provides the platform to integrate spatial and non-spatial information. A GIS re-presents (maps) the features on the earth’s surface and analyses them, based upon their attributes and location.

GNSS, Surveying and Mapping

Surveying is the art and science of measuring the surface of the earth and its features. It is used for determining the three-dimensional position of objects based on the distances and angles measurement between them.

LiDAR

Light Detection and Ranging or LiDAR, is the technology that utilises lasers to determine the distance to an object or surface. LiDAR mapping can be either airborne or terrestrial. In airborne LiDAR, a pulsed laser ranging system is mounted on an aircraft which is equipped with a precise kinematic GPS receiver and an inertial navigation system (INS).

Photogrammetry

As defined by the American Society for Photogrammetry and Remote Sensing (ASPRS), photogrammetry is the art, science, and technology of obtaining reliable information about physical objects and the environment through the processes of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiation and other phenomena. This technique is used to obtain coordinates of the required object-points, topographical and thematic maps and rectified photographs (orthophotos).

Building Information Modelling

BIM (Building Information Modelling) is not just about buildings as the name conveys. It is rather a 3D model-based process that gives infrastructure professionals the much-needed insight and apparatuses to let them plan, design, construct, manage and sustain the built-up environment on an ongoing basis. The entire process involves generation and management of digital twin of physical and functional characteristics of places.
