Industries: Land Development
Land Development Planning
Gold Coast Surveyors, Michel Group Services engaged Terranean to undertake a detailed LiDAR and Aerial Photography Survey of a 5 square kilometer development site near Nerang. The objective was to provide survey accurate data and ortho-photography over this heavily vegetated terrain at less than the cost of traditional field parties. Specifically 0.5m contours and 15 cm resolution ortho-photography were required as a basis for master planning over the site.
Terranean’s “eye safe” scanner enabled us to legally fly at low altitude, and this, together with the high pulse rate of the scanner, resulted in the capture of very high resolution data. This in turn ensured that a large number of points penetrated the thick vegetation canopy to generate a detailed ground elevation model (DEM).
Digital aerial photography was captured simultaneously with the LiDAR data thereby avoiding the extra cost of a second flight. The LiDAR surface model was used to ortho-rectify the digital photography and generate the 0.5m contours.
Combining the 3 data sets, the Michel Group was able to: extract valuable information such as existing infrastructure; make a flood risk assessment; and determine possible development locations.

PMM Group
Payne Road Development
The PMM Group is one of the largest land planning companies in Australia.
The Project
To construct an interactive 3D simulation of a planned residential development for the purpose of environmental impact assessment and urban design.
The Solution
A detailed DEM was generated from stereo aerial photography and updated
from engineering designs. A 360º photo montage of the background
was constructed from photographs taken on site. Textures were applied
for roads, lawn etc., and trees and other plants specifically representing
local forms were generated. Buildings representing actual planned structures
were created and placed within the simulation. An interactive interface
was developed for navigating through the development site within Windows
Explorer.
Multiplex Corporation
Kepperra Quarry
Multiplex Group is a diversified property business listed on the Australian Stock Exchange. Multiplex employs more than 1,800 people across four divisions including property funds management, property development, construction, and facilities management.
The Project
Stage 1 involved the construction of two interactive 3D models of the Keperra quarry in Brisbane. One model represented the current surface and the other represented the surface of a proposed residential development. A customised, interactive interface was developed to enable users to navigate around the site and compare existing and planned surfaces. The models are updated on a weekly basis and supplied to the client. The purpose is to ensure that current quarrying operations are consistent with the intended residential and commercial development, and convey information between quarry operators and the developers.
Stage 2 involved the construction of buildings, trees, and textures to create a realistic interactive representation of the proposed residential and commercial developments.
Jeju Island, Korea
Precision 3D modelling
The Challenge
Jeju Island is one of the most popular tourist destinations in South Korea. In recent times, the island has become a focus for development opportunities, due to the high levels of infrastructure investment. An affiliated company consulting to Jeju Development Corporation provided the opportunity for Terranean Mapping Technologies to provide hi-tech 3D visualisation services to the Koreans. Prior to this project, the only graphical images for the development were artistic drawings.
The challenge was to create a realistic fly-through of the projected development, with additional still shots. Terranean was required to incorporate the existing urban design and provide a feel for the resort layout. Accurate representation of the visual impact was crucial, and since the company agreed to undertake the project to demonstrate capability, it was essential to stay within budget constraints.
The Solution
Cutting-edge software, from a market-leading provider, provided Terranean with the opportunity to develop a 3D model of the resort on Jeju Island, with the minimum of difficulty. The project used the existing raster and vector data integrated with the urban design to create a fly-through movie as still frames.
The Result
The Jeju Island 3D modelling project provided the Korean Company a decision-support tool with which to appreciate the impact of proposed developments. A major part of its business, Terranean now supplies these services to the Tourism and Development Industries on a regular basis.
