Send Your Project DocumentsIn Brief
Viewshed Analysis is a GIS based visibility modelling technique used to identify where a proposed building, structure or development may be visible across the surrounding landscape. Using digital terrain data and line of sight calculations, it maps the locations from which a project may be seen, providing objective evidence to support design development and planning assessment.
The analysis is particularly valuable for elevated sites, complex terrain, renewable energy projects, telecommunications infrastructure and developments where visibility from roads, public spaces, neighbouring properties or recognised viewpoints may influence planning outcomes. Early visibility modelling allows project teams to better understand potential visual exposure before development applications are lodged.
Viewshed Analysis identifies where a development may be visible. It does not determine whether that visibility is acceptable or significant. That broader planning judgement is typically undertaken through a Visual Impact Assessment, which evaluates the landscape, planning and community implications of the mapped visibility.

Viewshed Analysis
Viewshed analysis is a visual and spatial assessment method used to understand the visibility of a proposed building, structure or development from surrounding locations. It helps identify where a proposal may be visible, where line of sight may exist and which surrounding viewpoints may be relevant to planning or design decisions.
In a planning context, a viewshed is the area from which a particular object, site or built form may be seen. For a development proposal, this may include visibility from public roads, reserves, nearby properties, elevated land, ridgelines, waterways, scenic corridors or other locations where visual exposure could matter.
The purpose of viewshed analysis is not to make a broad judgement about whether a proposal is visually acceptable. Its role is more specific. It provides visibility evidence, helping project teams understand where the proposal may be seen from before broader planning, visual impact or design conclusions are made.
For Certified Energy, viewshed analysis sits within the design and planning intelligence layer of the project process. It is especially useful when a development needs to be understood in relation to terrain, public viewpoints, surrounding built form or landscape visibility.
Viewshed analysis helps answer the question:
where can this proposal potentially be seen from?
When It Is Useful
Not every development requires Viewshed Analysis. It becomes valuable when site elevation, terrain, building height, public viewpoints or surrounding built form may affect where a proposal can be seen and when objective visibility evidence could assist design or planning decisions.
Development on hillsides, ridgelines, slopes or elevated land may be visible across a wider area than expected. Viewshed Analysis can map the potential visual catchment and help identify the locations from which the proposal may be seen.
Open landscapes, coastal areas, rural settings and scenic corridors often contain fewer visual obstructions. Visibility modelling can help establish how far a proposal may be seen across the surrounding terrain.
A proposal may need to be considered from roads, reserves, lookouts, waterways, walking routes or other recognised viewpoints. Viewshed Analysis helps determine whether a potential line of sight exists from these locations.
Upper storeys, roof forms, plant areas, towers and rooftop structures may remain visible above surrounding terrain or development. Visibility mapping can clarify the geographic extent of that potential exposure.
Where council, a planning consultant or another project stakeholder raises questions about visibility or line of sight, Viewshed Analysis can provide a consistent spatial evidence base for further assessment.
Early modelling can compare changes to siting, height, massing, roof form or screening before the design becomes fixed. This can help project teams understand whether design changes alter the extent of potential visibility.
Viewshed Analysis is most valuable when visibility is a genuine project consideration. It replaces broad assumptions with mapped evidence by showing where a proposal may have a potential line of sight and where further design review or visual assessment may be appropriate.

Assessment Method
Viewshed Analysis begins by defining the location, geometry and height of the proposed development. Depending on the project stage, the assessment may use an indicative building envelope, preliminary massing model or developed architectural information to represent the elements being tested for visibility.
The proposal is then positioned within a spatial model containing available terrain, topographic and surrounding context data. Relevant assumptions may be established for ground levels, observer height, existing buildings, vegetation and other features that could influence a potential line of sight. The accuracy and level of detail depend on the quality of the source data and the purpose of the assessment.
Observer locations are selected according to the planning question. These may include roads, reserves, lookouts, waterways, neighbouring streets, elevated land or other publicly accessible locations from which visibility may be relevant. A broader viewshed can also be generated to identify areas of potential visibility before individual viewpoints are examined in greater detail.
GIS based calculations test the relationship between the observer locations, intervening terrain and the proposed development. The analysis identifies where a potential line of sight exists, where terrain or modelled obstructions may screen the proposal and which areas may warrant closer investigation.
The findings are presented through visibility mapping, viewpoint information and clearly stated modelling assumptions. These outputs can support design development, planning discussions and the selection of locations for further assessment. Viewshed Analysis identifies potential visibility, but it does not independently determine the significance or acceptability of that visibility.
The site location, ground levels and relevant project elements are defined. The model may represent a building envelope, roof form, upper level, tower, plant area or other structure being tested for visibility.
Available terrain, topographic and surrounding context data are assembled within the GIS model. Assumptions relating to buildings, vegetation, observer height and potential screening are documented where relevant.
Relevant observer points or areas are selected from roads, public spaces, reserves, lookouts, waterways, neighbouring streets or other locations connected to the project’s planning context.
The model tests potential lines of sight between observer locations and the proposed development. It identifies areas where visibility may occur and where intervening terrain or modelled obstructions may provide screening.
The results are documented through visibility maps, selected viewpoint findings and stated modelling assumptions. These outputs help project teams understand where the proposal may be visible and where further design or visual assessment may be appropriate.

Visibility Modelling
At the heart of Viewshed Analysis is a simple spatial question: can an observer see the proposed development from a particular location? Line of sight modelling answers this question by analysing the relationship between observer locations, terrain and the proposed built form.
Line of sight analysis tests whether a direct visual connection exists between an observer location and the proposed development. It considers terrain, observer height, project height and any modelled obstructions that may interrupt visibility.
Rather than estimating visibility, the analysis uses spatial modelling to identify where a potential line of sight exists and where the proposal may be screened by the surrounding landscape or built environment.
The calculated line of sight results are translated into a visibility map that illustrates the geographic extent of potential visibility. This provides a clear spatial overview of where a proposal may be visible across the surrounding area.
These mapped outputs support evidence based planning discussions, design refinement and the selection of viewpoints for further investigation where required.
Areas where the proposed development may be visible from roads, reserves, public spaces or recognised viewpoints.
How terrain, ridgelines, slopes and surrounding landform may increase or reduce potential visibility.
Whether upper levels, roof forms, towers or rooftop structures extend beyond the surrounding built environment.
Which locations may benefit from additional assessment, such as photomontages or a Visual Impact Assessment.
Viewshed Analysis identifies where a development may be visible. It does not determine whether that visibility is acceptable or whether it creates a significant planning impact. Those questions are addressed through broader planning assessment and, where required, a Visual Impact Assessment.
Spatial Data and Modelling
The quality of a Viewshed Analysis depends on the quality of the spatial information used to build the model. Terrain, topography, observer locations, project geometry and surrounding context all influence how potential visibility is calculated and mapped.
Certified Energy combines planning knowledge with GIS based visibility modelling to produce practical planning intelligence. Depending on the project, available spatial datasets, digital terrain models and project information are used to develop a visibility model that reflects the purpose and stage of the assessment.
Specialised spatial capability is supported by Urbanfinity, providing technical expertise in terrain modelling, mapping workflows and spatial analysis. This allows Certified Energy to focus on project coordination, reporting and planning outcomes while drawing upon robust GIS capability where appropriate.
The result is a structured evidence base that supports design refinement, development applications and planning discussions through objective visibility modelling rather than assumption alone.

Viewshed Analysis remains a Certified Energy service. Urbanfinity provides specialist spatial capability that supports the underlying GIS modelling where appropriate, allowing project teams to benefit from robust visibility analysis alongside practical planning expertise.
Design Development
Viewshed Analysis delivers the greatest value before a design is finalised. By identifying where a proposed development may be visible early in the project, architects, planners and developers can make informed design decisions before documentation is complete or planning issues become more difficult to resolve.
Rather than relying on assumptions about visibility, project teams can use objective GIS based modelling to understand how changes to siting, building height, roof form or massing may influence the geographic extent of potential visibility. This provides practical evidence that can support design refinement throughout the planning process.
Because the assessment is based on spatial modelling, multiple design options can often be explored before a preferred solution is selected. This allows visibility to become one of several measurable design inputs alongside planning controls, site constraints and project objectives.
While Viewshed Analysis identifies where visibility may occur, broader questions relating to landscape character or visual impact can be considered separately if additional planning assessment is required. This allows each assessment to perform a distinct role within the overall project workflow.
Assess how different building locations, heights or massing options may influence the extent of potential visibility before design decisions are finalised.
Provide objective visibility evidence that can assist discussions with architects, planning consultants, councils and other project stakeholders.
Identify potential visibility issues before planning documentation is completed, reducing the likelihood of unnecessary redesign later in the project.
Where visibility modelling identifies areas requiring closer review, additional assessment such as Visual Impact Assessment or visual simulations can be undertaken with greater confidence.
Viewshed Analysis is most effective when it informs decisions rather than simply documenting them. Understanding potential visibility early gives project teams greater confidence to refine designs, prepare stronger planning submissions and focus additional assessment where it adds genuine value.
Development Applications
Many development applications require more than compliance with planning controls. Where visibility may become a planning consideration, Viewshed Analysis provides objective evidence showing where a proposed development may be visible across the surrounding landscape, streetscape or urban environment.
This information can help architects, planners and developers prepare more informed planning submissions by identifying potential visibility before questions arise during the assessment process. It also provides a clear spatial evidence base that can support discussions with councils, planning consultants and other project stakeholders.
Viewshed Analysis does not determine whether a proposal should be approved. Instead, it contributes reliable visibility modelling that can support planning reports, design refinement and, where appropriate, additional studies such as Visual Impact Assessment.
When undertaken early, the assessment allows potential visibility issues to be understood before planning documentation is finalised, reducing uncertainty during later stages of the development application process.
Support planning reports, design statements and development application documentation with objective visibility evidence.
Provide mapped visibility information when councils, planning consultants or other stakeholders request greater clarity about potential visual exposure.
Use visibility modelling during design development to test alternative building locations, heights or massing before submitting a development application.
Identify where additional investigations, including Visual Impact Assessment, photomontages or planning review may add value.
Viewshed Analysis provides objective visibility evidence that can strengthen planning submissions without replacing professional planning judgement. It helps project teams understand where visibility occurs, allowing planning decisions to be supported by measurable spatial information rather than assumption.

Visibility Factors
Visibility is rarely determined by building height alone. Terrain, observer location, surrounding development, vegetation and landscape openness all influence whether a proposed development may be seen from a particular location.
Roads, reserves, walking tracks, waterways, public open space and surrounding properties all provide potential observer locations from which visibility can be assessed.
Hills, ridgelines, valleys, slopes and elevation changes may either block or increase potential visibility depending on their relationship to the observer and the proposed development.
Open rural, coastal and undeveloped landscapes often allow visibility across greater distances than dense urban environments.
Existing buildings, structures and surrounding urban form may partially or completely screen a proposed development from selected viewpoints.
In some cases only roof forms, upper storeys, rooftop plant or other elevated elements extend above the surrounding context.
Depending on the available data and modelling assumptions, vegetation and other screening elements may influence potential visibility across the surrounding landscape.
Viewshed Analysis brings these factors together within a single spatial model, helping project teams understand how terrain, observer locations and surrounding context combine to influence potential visibility across the site.

Comparison Guide
Although these assessments are often used together, they answer different planning questions. Viewshed Analysis identifies where a proposal may be visible, while a Visual Impact Assessment considers whether that visibility is likely to create a significant visual planning issue.
A GIS based visibility assessment that maps where a proposed development may be seen from surrounding observer locations.
A planning assessment that evaluates the significance of visibility within its landscape, community and planning context.
Viewshed Analysis can be completed as a standalone visibility study or used as a technical input to a Visual Impact Assessment. By first identifying where a proposal may be visible, project teams can better understand whether a broader assessment of visual significance is likely to be required.
Related Site Studies
Viewshed Analysis is one of several specialist site assessments used during planning and design. While these studies are often prepared for the same project, each focuses on a different relationship between the proposed development and its surrounding environment.

Viewshed Analysis focuses on visibility and line of sight. Shadow Diagrams evaluate overshadowing, Sun Eye Diagrams assess solar obstruction and Daylight Modelling measures daylight performance. Together these studies provide a broader understanding of how a proposed development interacts with its surroundings while maintaining clearly defined purposes.
Common Project Types
Viewshed Analysis is used across many sectors where understanding potential visibility supports planning, design or stakeholder engagement. While every project is different, the following development types commonly benefit from visibility modelling.
Wind farms, solar farms, battery energy storage systems and associated infrastructure often require visibility modelling across large geographic areas.
Telecommunications towers, antennas and associated structures frequently require line of sight and visibility assessment during planning.
Bridges, water infrastructure, transport projects, utilities and other public infrastructure may require visibility modelling during planning and design.
Homes, apartments and mixed use developments on elevated or visually prominent sites may benefit from understanding potential visibility before planning lodgement.
Lookouts, visitor facilities, accommodation and developments within coastal or scenic landscapes often require visibility modelling as part of the planning process.
Warehouses, processing facilities, industrial buildings and commercial developments may use Viewshed Analysis to understand potential visibility within the surrounding area.
The suitability of Viewshed Analysis depends less on the type of development than on its visibility within the surrounding landscape. Projects with greater height, wider visual catchments or more exposed locations are generally more likely to benefit from visibility modelling during planning and design.
Project Information
The information required depends on the purpose of the assessment and the stage of the project. Early design studies may only require a site location and an indicative building envelope, while planning submissions often benefit from more detailed drawings and supporting information.
If the assessment has been requested by a council, planning consultant or another project stakeholder, including that request helps ensure the analysis addresses the specific planning question. This allows the scope of work to be tailored to the project rather than preparing unnecessary modelling.
You do not need a complete documentation package before contacting Certified Energy. We can review the information available, identify any important gaps and recommend whether a Viewshed Analysis, a Visual Impact Assessment or another assessment pathway is likely to be the most appropriate.
Most projects begin with a preliminary review of the available information. From there, we can recommend the most appropriate assessment scope, identify any additional project information that may be required and explain how the visibility modelling can best support your planning or design objectives.
Modelling Assumptions
A Viewshed Analysis models potential visibility using available spatial information and project geometry. Like any technical model, the results depend on the quality of the input data and the assumptions applied during the assessment.
The analysis identifies locations from which a proposal may be visible. It should always be interpreted alongside an understanding of the available terrain information, building representation, observer locations and any assumptions adopted during the modelling process.
Clearly documenting these assumptions helps ensure the results are transparent, repeatable and appropriate for the intended planning or design purpose.
Concept envelopes, architectural drawings or detailed 3D models all influence how the proposed development is represented within the visibility model.
Digital terrain models and elevation data form the basis of line of sight calculations, with output quality reflecting the available spatial datasets.
Visibility results depend on the observer locations selected for assessment. These should align with the purpose of the project and the questions being investigated.
Buildings, vegetation and other physical features may or may not be represented depending on the available datasets and agreed modelling methodology.
A well prepared Viewshed Analysis clearly explains the datasets, modelling assumptions and methodology used. This allows project teams to interpret the visibility results with confidence and understand the scope of the assessment.
Understanding the Limits
Viewshed Analysis is a powerful GIS based planning tool for identifying potential visibility. However, visibility alone does not determine planning outcomes. Many development applications require additional assessment to understand the significance, context and planning implications of what the visibility modelling reveals.
A viewshed identifies where a development may be visible, but it does not determine whether that visibility creates a significant visual impact. Understanding visual effects requires professional interpretation within the broader planning and landscape context.
Visibility alone does not determine whether a development will receive planning approval. Consent authorities also consider planning controls, environmental impacts, design quality, community considerations and other technical assessments.
GIS visibility modelling is based on terrain and available spatial data. Site inspections, planning review and project specific investigations remain essential for understanding local conditions and supporting informed development decisions.
A viewshed map illustrates potential visibility rather than the appearance of a proposed development. Photomontages, visual simulations and Visual Impact Assessments are often used alongside visibility modelling to communicate how a project may be experienced from key viewpoints.
The greatest value of Viewshed Analysis comes from combining objective visibility modelling with complementary planning studies. Together, these assessments help planners, consultants and consent authorities understand not only where a development may be visible, but also how that visibility should be considered within the wider planning framework. This integrated approach supports more robust evidence based decision making throughout the development assessment process.
Planning Assessment
Planning authorities must consider how visible a proposed development will be within its surrounding landscape. Viewshed Analysis provides an objective way to identify where a project can be seen, helping councils understand potential visual exposure before assessing planning impacts or broader visual significance.
Rather than relying on assumptions or selected viewpoints alone, Viewshed Analysis uses digital terrain data to calculate where a development may be visible across the surrounding landscape. This creates a consistent and repeatable evidence base that supports transparent planning decisions.
Many developments require planners to understand how far visual effects may extend beyond the project boundary. Visibility mapping helps identify affected roads, residential areas, parks, public lookouts and other sensitive locations before more detailed assessment begins.
Early visibility modelling allows potential planning issues to be identified before design decisions become fixed. Understanding where a project is visible can assist project teams in refining building placement, height or screening measures before formal submission.
A Viewshed Analysis identifies where a proposed development may be visible. It does not determine whether that visibility creates an unacceptable planning outcome. Councils typically combine visibility mapping with planning controls, landscape character studies and Visual Impact Assessments to understand the broader significance of those views before making development decisions.
