SURVEYING AND GEOMATICS ENGINEERING


Are you a technology enthusiast? If not, you might want to become one because the domain of Geomatics, including land surveying is significantly transformed and diversified by new technology and paradigms and you do not want to get left behind.

Some years back our profession was simply called “land surveying” which meant accurately measuring points located on or near earth surface. These points represented objects such as buildings, roads, rivers or the bare ground or delineated property boundaries. A land surveyor has been changed. There is total revolution in the field which does not only transformed the land surveyors to Geomatics but also expand the technology. Image

Geomatics is the art science or technology dealing with the acquisition, storage, processing, production, presentation, and dissemination of Geoinformation. Geomatics is undergoing dramatic changes at previously unseen places. Now a day’s Geodata is acquired, processed, analyzed and stored or radically differently than before.  Some factors that have altered the face of surveying profession include GPS, photogrammetry, lidar, UAVs, crowd sourcing, GIS and integrated total stations. Since GPS was first introduced in US in 1983 the growth use of this revolutionary new surveying tool has been phenomenal. In 1970s ancient surveying equipment were transformed to total stations. Paper registration is no longer required as highly computer software now automatically converts direction and distances into 2D and 3D coordinates. Today a system for tracking the prism and a communication link allows just one operator to carry out a survey task while controlling the instrument form prism pole. These robotic total stations are enable unmanned deformation monitoring of dams and automatic guidance’s of dozers, grades and other machines. The birth of space technology resulted in two revolutionary ways of Geodata acquisition being developed: positioning and navigation using global navigations satellite system (GNSS) and optical and microwave sensing from space. GNSS enable precise positioning and timing information to be obtained anywhere, day or night with high precision, reliability and at affordable cost. The land surveying profession is not defined by the available tools, but rather by the knowledge of how to use and adjust them to generate high quality Geodata in its full spatial dimension.Image

 

Geomatics engineering is an exciting, rapidly growing science of the future. This include various fieldworks for weeks, projects etc. Geomatics engineering covers land use management, land surveying, environmental modeling, programming, GIS, remote sensing, project management etc. environmental modeling includes agriculture, water, ecology, oil, gas, forestry and mining application. This is fit for those who love to work out door. There is strong need of publicity of this to fulfill the need in time. Surveyor arrive in on site in the morning position their instruments or look at display and when they leave again in the evening, nothing has changed or perhaps some nail have been hammered into the place. How can a profession be promoted without impressive products and appealing icons. Now it time that appeal students, organization and national to promote this emerging science and technology “GEOMATICS ENGINEERING”.
