Deformation prediction of a high-piled wharf
Xiaodong Yi, Erhu Wei and Chengke Jiang

The high pile wharf has the advantage of slight wave reflection, steady anchoring condition, little investment and the construction time being short. Therefore it has been widely used in coastal areas where the ground has soft soil. But, on the other hand its penetrant structure raises some problems also for the structure. In order to guarantee the request of ships draft, the front water area of the wharf has to be dug more deep,…

The term Terrestrial 3D Laser Scanning scan is commonly referred to the process of collecting large number of data points through high performance hardware devices (3D Laser Scanners) delivering raw data outputs in the form of point clouds or cloud of points (CoP). The concept of High-Definition surveying, on the other hand, extends the capabilities of 3D Laser Scanners by providing effective field and office workflow solutions in combination…

An inertial navigation system (INS) is a self-contained navigation system that primarily measures position, velocity and attitude. The system’s inertial frame measures the accelerations and the rotations by using an inertial measurement unit (IMU). The IMU is a group of six inertial sensors which are three linear accelerometers and three gyroscopes (gyros)…

“We are convinced that if we are to play a meaningful role nationally, and in the community of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.”…

In the rapidly changing economic, technological, political, and social environment that characterises the world as we see it in the 21st Century, every profession faces major challenges, surveying being no exception. While some of these challenges are common across all professions, others are specific to the surveying community. In this discussion I choose to separate the challenges facing the surveying profession into these two categories…

on ‘Bhuvan’

How do you envisage the role of Bhuvan?
The role is very clear; it is an Indian Earth Observation visualisation portal. Over the past two decades, ISRO has spearheaded myriad unique applications …
