摘要: An interactive, dynamic map has been built using videodisc technology to engage the user in a simulated “drive” through an unfamiliar space. The driver, or reader, is presented with either sparsely sampled sequences of images taken by single frame cameras that replicate actual imagery from space, computer synthesized replicas those images. reader may control speed, route, angle view and mode presentation this information thus tour area. In addition, he access spatially stored ancillary data buildings locales environment. This basic being enhanced provide topographic views, incorporate optical electronic image processing more responsive, visually complete representation
