Industries: Local Government
Ipswich City Council
Detailed Contours and High-resolution Ortho-rectified Mosaics
The Challenge
 |
 |
Ipswich City is one of the largest and fastest growing local authorities in Australia. South East Queensland is continuing to experience unprecedented population growth, and the recent state government regional plan earmarked Ipswich City to accommodate much of this future growth.
High-quality mapping is a prerequisite to plan for this growth. Terranean Mapping Technologies was engaged to undertake a detailed mapping project covering the entire 1200 square km Council area.
The Project
Terranean initially arranged capture of 1:12,000 and 1:40,000 scale aerial
photography and provision of photographic contact prints. We used entirely
digital processes and systems to extract a detailed DEM,
which in turn was used to generate 1.0m and 5.0m contours and high-resolution
ortho-rectified mosaics. Buildings and associated features were extracted
for integration into the Council’s asset management database.
The Result
A distinguishing feature of this project is the high level of customer satisfaction. It has been generally recognised that this mapping work is the best quality that Council has had produced, during the 12 years that Council has been integrating aerial imagery as part of its corporate GIS system.
Frankston City Council
High-resolution Ortho-rectified Mosaics
The Challenge
Frankston is a progressive regional city adjacent to Melbourne, on Port Phillip Bay, which has a strong emphasis on maintaining lifestyle. A prerequisite for maintaining these values is a strong planning ethic, and high quality maps are an essential part of this type of planning.
In 2004, Terranean Mapping Technologies was engaged to undertake a detailed mapping project covering the entire Frankston Council area.
The Project
Terranean arranged capture of 1:5,000 and 1:10,000 scale aerial photography and used entirely digital processes to create a detailed DEM. This was used to generate high-resolution ortho-rectified mosaics, which were integrated into the Council’s on-line asset management database.
The Result
Again, quality expectations were exceeded and Council staff acknowledged that this was the best mapping base that they had ever worked with.
Sutherland Shire Council
Historical Mapping Project
The Challenge
Sutherland Shire is one of the largest urban councils in NSW. It encompasses a variety of landscapes ranging from the urban fringe of Sydney, Botany Bay, and the historical Royal National Park.
The area is characterised by growth and rapid change. In order to address a perceived need to understand the dynamics of this change, Terranean Mapping Technologies and Council together embarked on a challenging partnership to provide a record of the changes during the decades.
The Solution
The NSW Department of Lands stores a library of historical photographs over the whole state. The Department and Terranean engaged in discussions with a view to locating and accessing historical images over Sutherland Shire. This was not a standard procedure and the Department of Lands and Terranean needed to develop agreements and processes to find, capture, and use the relevant images.
After agreements were reached and processes developed, Terranean processed the scanned aerial images from the Department of Lands and a DEM from the Council, to produce historical ortho-rectified mosaics.
The Result
The partnership has been a success and Sutherland Shire now has ortho-rectified mosaics of imagery from the 1940’s, 1950’s and 1980’s. Planners can now quickly overlay historical imagery over present data within their GIS, in order to gain an understanding of the changes that have occurred in the past. This represents an invaluable tool for this environmentally aware Council, enabling them to provide better management of growth into the future.
This project is of particular interest to other Councils in NSW, as Terranean has invested in streamlining its procedures for quickly locating, gaining access to, and scanning historical aerial photography, and producing rectified mosaics. In the future, Terranean can offer a cost-effective service to any other local government authority.
Terranean now offers this service in all other Australian states.
Barcoo and Ilfracombe Shire Councils
Mapping Project
 |
 |
The Project
Barcoo and Ilfracombe are remote rural shires in Western Queensland. Local Engineers and Planners, George Bourne and Associates, engaged Terranean Mapping Technologies to undertake detailed mapping over the four key towns within the two shires.
Terranean Mapping Technologies applied the latest digital mapping techniques to supply a quality, yet cost-effective solution to these two low-rate base councils.
Terranean arranged capture of 1:10,000 scale aerial photography and provision of photographic contact prints, followed by extraction of detailed feature data across each of the towns. Vegetation, hydrography, roads, buildings, DEM’s and 1.0m contours, as well as other feature data were extracted and integrated for asset management use within the Councils’ GIS. Ongoing services include production of photographic enlargements as required.
The Result
An efficient and reasonably costed project was completed using the latest in digital technologies to meet the practical needs of two remote rural councils.
