The San Francisco Public Utilities Commission (SFPUC; San Francisco, California) commissioned Solid Terrain Modeling (STM; Fillmore, California) to create 3-D solid terrain model of the San Francisco area.

The San Francisco model is featured in an energy-efficiency display at San Francisco City Hall's South Light Court. Designed to exemplify the Mayor's Energy Conservation Account, the display focuses on the city's commitment to renewable power sources and energy-efficient equipment.

The 3-ft by 3-ft (1-m by 1-m) 3-D STM model shows every street, with miniature models of eight famous San Francisco landmarks and 30 flags identifying locations of various MECA initiatives. A plaque affixed at the front of the display has text that highlights the MECA program and a legend for the color-coded flags: Energy Star® certified refrigerators, new lighting, solar generation, heating/cooling and co-generation.

The eight stylized landmarks include the Transamerica pyramid building, Coit Tower, the Golden Gate Bridge, Pacific Bell Park (Giants' Stadium), City Hall and three others. Andrew Hardardt Design and Mitchell Design conceptualized and designed the display. Elevation data for the model were supplied by the US Geological Survey; imagery came from AirPhoto USA.

“The San Francisco STM model illustrates how our models can convey important information in an interesting and useful format,” said Gary James, STM vice president, sales and marketing. “We can add pertinent details and features to each model that help communicate a client's message to their target audience.”
