Tangential View Metrics Quantify Visual Pollution from Outdoor Advertisements

Landscape metrics, specifically tangential view metrics, can be employed to objectively measure and analyze the impact of outdoor advertisements on visual pollution within urban landscapes.

Land · 2020

Key Findings

01Visible area metrics are highly sensitive indicators of visual pollution.
02Maximum visible distance metrics demonstrate the negative impact of advertisements on view corridors.
03The directional nature of viewsheds influences the perceived distortion of the cityscape.
04Shannon depth and depth line metrics were not statistically significant indicators of visual pollution in this study.

Application

Design takeaway

How to apply

When designing or reviewing urban spaces with significant outdoor advertising, use GIS tools to calculate visible area and maximum visible distance metrics to assess the extent of visual pollution and its impact on sightlines.

Project actions

01Consider using GIS software to analyze visual impacts in your design projects.
02Explore how different types of advertisements affect visual pollution differently.

Method & Evidence

AimCan tangential view landscape metrics be used to quantify visual pollution caused by outdoor advertisements and assess their impact on the visual landscape character?

MethodQuantitative analysis using geospatial data and landscape metrics.

ProcedureSimulated pedestrian viewsheds were generated using aerial laser scanning data to analyze the visibility of outdoor advertisements. Various tangential view landscape metrics (visible area, maximum visible distance, skyline, Shannon depth, view depth line) were calculated and interpreted in relation to visual pollution and visual landscape character.

ContextUrban landscape design and planning, specifically the impact of outdoor advertising.

Variables

IVPresence and characteristics of outdoor advertisements (e.g., size, density, location).

DVMeasures of visual pollution (e.g., visible area, maximum visible distance) and visual landscape character.

CVTopographic conditions, view direction, interval of viewshed sampling.

Strengths & Limitations

Strengths

+Introduces a novel application of landscape metrics to visual pollution.
+Provides a quantitative and objective methodology for analysis.

Limitations

The accuracy of the analysis depends heavily on the quality of the digital elevation model and the precise location data of advertisements.

Reliability & validity

Reliability could be improved by using standardized software and consistent parameters for viewshed generation. Validity is supported by the statistical significance of some metrics, but subjective perception of visual pollution remains a challenge to fully capture.

Think critically

How might the cultural context or local regulations influence the perception and impact of visual pollution, and how could these factors be incorporated into landscape metric analysis?

Design Principles

"Objective measurement of visual impact is essential for effective urban design and landscape management."

Understanding and quantifying visual pollution is crucial for designers and urban planners aiming to create more aesthetically pleasing and less cluttered environments. This research provides a methodological framework for assessing the visual impact of advertisements, moving beyond subjective opinions to data-driven analysis.

What This Means for Your Design

This research shows how we can use computer tools to measure how much outdoor ads clutter up our views in cities, helping us design better spaces.

How to use in your project

1.Use the methodology described to quantify visual pollution in a chosen design context.
2.Discuss how your design choices mitigate or exacerbate the visual pollution identified by these metrics.
