Envisioning Cities

Image manipulation software, like Adobe Photoshop, can be a powerful tool to involve communities in the process of urban development.

From the Local Government Commission:

Computer Simulation as a Public Participation Tool

“Most of us have a hard time envisioning what two-dimensional plans or a development proposal will look like when built. Computer simulation translates such plans and descriptions into pictures that help us see what a proposed development will actually look like. This allows residents and policymakers alike to make more informed planning decisions.

Simulation exercises help settle complex planning issues and guide design and planning activities. As a mechanism to improve public communication concerning local planning and development issues, computer simulation can be used to

• Help develop design guidelines
• Evaluate controversial proposals
• Analyze urban design qualities before formal discussion begins on an actual proposal
• Develop choices about the appearance of a project

Before the advent of personal computers, architects and urban designers were only able to show their clients what a proposed project would look like through artist’s renderings and/or by constructing elaborate three-dimensional models. Such models and renderings are expensive and time consuming to produce.

Today, advances in computer technology, such as computer aided drawing and design (CADD), global information systems (GIS), and advanced two and three-dimensional graphics software, have made it possible for design professionals to present their projects to clients or the public through computer simulation. Computers make it possible to produce highly accurate simulations faster and less expensively than do traditional methods. Furthermore, once computer simulations are produced, they can be easily adapted to design changes. An artist’s rendering, in contrast, may have to be completely redrawn.

Computer simulation begins with a scanned photograph of a building or area within a community. Using computer software, elements of the image are added, taken out, or otherwise reorganized into a new image representative of a proposed development design strategy. The result is a series of before and after images...

This technique allows all stakeholders to see the differences in proposed design styles and development patterns and allows decision-makers to evaluate the potential impacts of proposed developments.”

From the company Urban Advantage:

“Working with architects, planning staff, and citizen groups, we create visions of pedestrian-friendly, socially-interactive communities by transforming photographs with photo-editing software. In addition to the illustration skills necessary to make seamless montages, we also incorporate into the images an understanding of urban planning, architecture, arboriculture, and transportation. This results in informed collaboration with clients.”

Some of their before and after photo simulations are truly stunning — though after a while, the solutions do start to look a lot alike.

The LGC page lists serveral other specialist firms that provide illustration services, but with the increasing power of home computers and the increasing popularity of digital cameras and image manipulation software, I imagine that community residents themselves might also be able to render their own visions.
