Spatial Sciences

Our world is changing. Fast access to high quality geographic data and information is now critical for decision makers in every industry. By combining geographic data with other business information, organisations can see trends and generate meaningful intelligence to streamline internal processes and improve performance.

GHD's award winning spatial sciences team uses Geographic Information System (GIS) technology to acquire, compile, manipulate, interpret and visualise data to reveal geographic patterns and relationships. By bringing together large volumes of disparate data, decisions that were once largely based on guess work, become more quantitative and can be powerfully presented using map-based tools.

GHD has a reputation for innovation. We can be involved at all stages of delivery - from planning and project management, through to data acquisition, processing, modelling, reporting, map production and web deployment.

Work with us and get a grip on GIS.

Alternative Water Atlas - Melbourne, Victoria


GHD was commissioned by Victoria’s Smart Water Fund to explore, cost and quantify the opportunities for alternative water sources across Melbourne, taking into account the spatial variability inherent in these opportunities.

The project analysed four alternative water sources – centralised wastewater recycling, de-centralised wastewater recycling (sewer mining and blackwater treatment plants), stormwater harvesting and rainwater harvesting. The project considered the water demands that these different sources could supply across the Melbourne region, by quantifying and mapping the locations of substitutable demands up to the year 2060. Spatial analysis identified potential opportunities for each alternative water source, and a water supply–demand balance was undertaken to quantify the yield of the alternative water opportunities.

Asset Management Information System Integrations, Manila Water


Manila Water engaged GHD to develop and implement its asset management information system blueprint, as part of an Enterprise Asset Management (EAM) improvement program. Our role included development, tendering, contract management and implementation.

In addition to the blueprint, we developed a comprehensive plan for 34 identified integrations, involving nine different systems (SAP, Works Management, Capital Works, GIS, SCADA, Finance, Business Intelligence, Customer Relationship Management & Metering).

Critical Water Pipe Analysis


With the demand for water resources increasing in communities with an aging infrastructure, it is becoming increasingly important for cities to be proactive in developing approaches for preventative maintenance. The Town of Markham is one local authority developing strategies to reduce the frequency of water main breaks and subsequent community impacts.

GHD was engaged to collaborate with the Town of Markham’s Waterworks Department to establish a framework and spatial tool to undertake a semi-automated risk assessment and to identify critical water pipes in high risk environments. Our services included:

Great Eastern Highway Upgrade - Western Australia


In an era where project teams are widely distributed between cities or even continents, online mapping provides a mechanism to share and distribute the most up to date geographic information to any desktop, whether it be next door or across the globe. Web mapping is now a core component of integrated information systems and the majority of planning and infrastructure projects rely heavily on geographic data to make effective decisions.

GHD recently developed an integrated web mapping application to support the design and construction of the Great Eastern Highway upgrade in Western Australia. The application provided a mechanism for geographically diverse project alliance partners and the community to view and query high resolution aerial photography, road designs, neighbourhood infrastructure, environmental constraints and property information in real-time via a web browser, with no end-user requirement for expensive or specialist GIS software.

Habitat Mapping of Klamath River Corridor - California


GHD was commissioned by the Yurok Tribe to improve habitat mapping of the Tribe’s 64,000 acre reservation, which is located along the Klamath River in far northern California. The primary goal was to develop GIS layers that would better enable wildfire risk modelling and to provide an improved basis for habitat conservation planning and forestry practices.

GHD utilised a combination of remote sensing, GIS and field sampling activities to produce a customised vegetation model and habitat classification map. This included an analysis of LiDAR in the context of canopy height, regional geologic and soil data, existing vegetation data, and field validation. An unsupervised spectral classification of 4-band orthoimagery was undertaken to partition the study area into stratified clusters of presumed vegetation categories. Target vegetation classes were then identified via local ecological knowledge, including input from ecologists, timber managers and Tribal members. The result was a preliminary vegetation class model and base map that was used to conduct stratified field sampling for confirmation and training of the model.

Provincial Data Capture Specifications for Hydrographic Features


The Ontario Ministry of Natural Resources (MNR) identified a need for mapping specifications of hydrographic features to support accuracy and consistency in the collection of comprehensive GIS data at a large scale (1:1,000 to 1:5,000).

The GIS data to be collected according to these specifications is used operationally by Ontario Government Ministries, Conservation Authorities, Municipalities, and private sector agencies, and is necessary to support a wide range of Ontario government priorities and Provincial Acts. Conservation Authorities have a particular need for large scale GIS data as they are directly responsible for defining regulated areas (Conservation Authorities Act) and local level water budget assessments (Clean Water Act).

Traffic Hazard Study - Guam


The territory of Guam’s occurrence of traffic accidents is higher than the national average resulting in property damage, injury and loss of life. Our team was commissioned to conduct an analysis of four years’ worth of traffic accidents throughout the island. A highly interactive, easily updatable GIS geodatabase was developed to identify the island’s most dangerous intersections for targeted safety modifications.

The system required working with the Guam Police Department to review 5000 paper-based traffic accident reports. The team then extracted key information into a database and mapped the location of each accident. The extracted data and mapped locations were linked and an analysis was undertaken to consider the type of accident, severity of accident, time of day, day of week, age of driver and weather conditions. The statistical frequency of accidents was also considered. The results were used to identify and further examine the most dangerous intersections on the island, with a series of recommendations made for techniques to increase the operational efficiency of the transportation system and to reduce the factors that were leading to traffic accidents.

Western Sydney Airport Environmental Impact Statement (EIS)


GHD was engaged by the Commonwealth Government as the lead consultant for preparation of an Environmental Impact Statement (EIS) for the new Western Sydney Airport.

The Australian Government announced Badgerys Creek as the site of the proposed Western Sydney Airport in April 2014. Planning and assessment for the airport was divided into two key stages.

Work and Asset Management Program - North Carolina, USA


GHD assisted the City of Charlotte with the implementation of a Work and Asset Management (WAM) program to more effectively maintain, replace and manage water and wastewater infrastructure. This incorporated implementation of a GIS-centric computerised maintenance management system (CMMS) to provide continual end user access to more than 300 employees.

Existing maintenance work flows were documented and future work flows recommended based on GHD’s asset management practices, CMMS system capabilities and the City’s desire to continually improve its maintenance practices. Over 100 service request and work order templates were created to allow users to record work activities, account for project labour, material costs and to coordinate follow-on work related to a specific event. Key functionality included the ability to attach supporting documents, video, images or notes to all service requests and work orders while tracking work status, completion requirements and regulatory requirements.
