Here are two quick images of a streetscape elevation made from rectified photographs of Charleston SC’s King Street (at the intersection with Queen Street). These were produced using photogrammetric techniques and are dimensionally accurate when plotted to scale.
Below is a cropped view showing the image’s rich resolution.
This type of imagery can provide with a powerful database of architectural conditions on an urban scale. This is especially true when such a database is enriched/managed over time.
Of course, the variety of graphic spin off uses is rich as well…
