Monitoring and ReportingGeoimage recognises the challenges of delivering sustainable infrastructure projects and has the tools to help. From Feasibility and Planning stages through to Design and Construction, Geoimage can assist in efficient planning of projects through the provision of information for evidence-based reporting.

Evidence-based Monitoring and Reporting on Projects

Ongoing reporting and monitoring benefits from the considered incorporation of spatial data. We can assist you in conducting infrastructure and asset audits and also develop processes for informing long term environmental monitoring programs of sensitive ecosystems including wetlands, vegetation, turbidity or seagrasses.

Compliance with environmental reporting and monitoring regulatory requirements necessitates the input of high quality up-to-date data throughout the project lifetime. Geoimage has the capacity and tools to carry out sophisticated spatial analysis to inform and support project management, design, development and site rehabilitation.

Imagery and derived products are available in a wide range of formats, which can be readily integrated into existing spatial infrastructure at any phase of a project.

Communicating the Project

Geoimage assists you to consolidate and standardise your spatial data for input into GIS databases. Should you require, we will develop standard operating procedures so that you can integrate spatial data into your own GIS.

In collaboration, we develop packages for the effective communication of project design and implementation features to community, interest groups, government and other stakeholders. Your data is a valuable resource that can be visualised as maps, 3D models, through web portals and more.

Investment into information at a variety of scales can also be used to deliver visual communication tools for community and stakeholder engagement.

GEOIMAGE RECOMMENDS:✜ Multi-temporal, repeat captures

for the duration of the project or at key project milestone phases.

✜ Land cover mapping to identify development footprints and impacts to provide metrics at reporting intervals.

✜ Use of a variety of spatial data for evidence-based reports.

Repeat satellite images can capture baselines and changes through time to monitor project progress.

Clients typically come to us throughout the Engineering cycle requiring high quality data to assess project development. They want to know…

What tools are available to cost-efficiently understand and communicate our project?Geoimage supports by:

✜ Procuring data for reporting on project progress and status.

✜ Conducting analysis of imagery and spatial data for use in evidence based reporting and to better understand project risks.

✜ Consolidating and standardising satellite, spectral and ancillary spatial datasets and providing standard procedures for their use throughout the project.

✜ Developing packages for the visualisation of projects for better communication of project objectives and outcome to both internal and external stakeholders.

Early in the feasibility and planning of a major proposed project there is an opportunity to save overall costs through appropriate site or route assessment, hazard avoidance and constraint mitigation. We offer innovative services to support feasibility studies and initial site/route selection.

Collecting and Analysing Spatial Data

Satellite imagery at broad scales provides a cost effective mechanism for obtaining data over the entire project site. With a large archive and relatively low entry price, mid-resolution data can be used to understand overall project areas and identify priority areas within your project site for further in-depth investigation with VHR satellite imagery. The integration of satellite derived spectral products with terrain data, geology, spatial statistics and other pre-existing spatial datasets can provide vital inputs to identify and map development constraints and assist you in assessing the feasibility of any proposed project.

To satisfy government regulatory compliance requirements, Geoimage provides services to map sensitive environments or other constrained land uses (good quality or strategic agricultural land for example) at a refined scale (1:10,000) to generate detailed, up-to-date inputs for planning.

Terrain Models and 3D Visualisations

Digital Elevation Models (DEMs) are an integral part of any geospatial analysis. DEMs, from 1m to 30m contours, are generated from satellite imagery captured in stereo-mode and are used extensively in this project phase to beter understand topography and terrain. They are also used to build 3D Models that are often developed as part of the planning phase.

The resolution of a DEM is normally twice the pixel resolution of the source imagery and the vertical accuracy is dependent on the accuracy of the sensor used to capture imagery. For example, DEMs generated from the highly accurate and agile WorldView-1 and WorldView-2 satellites have a spatial resolution of 1 metre and a relative vertical accuracy of 0.5m to 0.7m. In the majority of cases the area to be covered by a DEM from VHR stereo imagery is programmed for fresh capture, restricting the imagery and processing costs only to the critical area needed.

Feasibility and Planning

GEOIMAGE RECOMMENDS:✜ Broad-resolution imagery for site feasibility assessments.

✜ Land cover/land use classifications for up-to-date regional assessments and proximity analysis.

✜ Elevation data to aid terrain analysis.

✜ Use of an extensive range of archive imagery.

✜ Early spatial integration and the use of satellite imagery can provide valuable information from which to make decisions.

Client’s typically come to us at this phase of an existing project. They want to know…

Can it be done?Geoimage supports by:

✜ Establishing the project baseline through the procurement of broad scale imagery and the derivation of spectral and terrain products.

✜ Carrying out spatial analysis to identify project constraints and fatal flaws.

Having established the feasibility of the project, identifying and selecting the most valuable solution becomes the focus.

Supporting Value Engineering Management

Very high resolution satellite data is available for in-depth analysis and mapping of existing infrastructure, and environmental or cultural features. Once key sites have been identified Geoimage will task areas for imagery capture for baseline monitoring and reporting purposes.

Supporting the Development of the EIS

Satellite data is often used to baseline current environmental conditions, through mapping of land cover and vegetation extent, health and density.

Integration of on-ground field data can enable the identification of vegetation communities across the development site. This information can be used in analysis to update state-wide mapping products with greater detail and indicate the location of possible offset sites. It may also be used to make decisions to minimise, avoid or mitigate construction impacts.

Optioneering

GEOIMAGE RECOMMENDS:✜ Integration of broad-resolution satellite data with DEM and

VHR satellite imagery over potential key sites.

✜ Analysis of multiple spatial datasets and satellite imagery

for detailed understanding of stakeholder requirements,

infrastructure and facility access restrictions.

✜ The generation of fine scale GIS layers based on up-to-

date imagery for input into decision support tools.

Spatial data is often the key ingredient for objectively

comparing sites and routes at the Optioneering phase.

Throughout the Design and Construction phase your imagery and spatial data investment continues to inform the decision making process. As your project draws to a close your investment will provide ongoing support for decision making and monitoring beyond the lifetime of the project.

Risk and Value Management

Decision-makers will find that spatial data is an invaluable support tool for driving further innovation, mitigating risks and creating efficiencies. We have developed unique products for supporting infrastructure development projects. Our “Boggy Index”, which integrates elevation, rainfall, soils, geology and spectral data to identify areas that are difficult to traverse and operate in under wet-weather conditions, has been developed to aid decision making regarding site access and selection of lay-down and temporary site points. It can also be used to identify areas that dry rapidly or are consistently exposed to drainage issues. This valuable information can assist you to optimise site access and assists in reducing both costs and risks associated with a project.

Ongoing Monitoring of Development Impacts

Assessment and monitoring sensitive, natural and cultural features is vital for pre-empting and managing areas of possible long-term damage. We provide services to establish ongoing monitoring programs through repeat satellite captures. Our analysts have the tools and skills to derive imagery products to identify the location of development impacts and track changes in environmental parameters and cultural features to measure effectiveness of management practices in place. Satellite monitoring programs can be a cost-efficient method to identify when to initiate management actions on the ground.

Asset Management

In daily operation our products can be used to cost-effectively collect asset and facility information. There is a vast constellation of VHR satellites now in orbit, making high frequency monitoring through repeat capture a realistic option. Through the use of advanced classification techniques, Geoimage identifies and maps features of interest and integrates derived products with ancillary datasets. These products are then input into multi-temporal studies to quantify construction rates and map asset changes over the lifetime of the project.

Design andConstruction

GEOIMAGE RECOMMENDS:✜ Repeat satellite capture of sites in the construction phase.

✜ Combining imagery with derived products including “as-built” Infrastructure delineation, dust impact extents for progress
