This image is a historical map titled "The Pittsburgh Survey" from 1908, created under the direction of Shelby M. Harrison. It provides a statistical representation of the ratio of new dwellings erected between 1899 and 1901 to the total number of buildings standing as of February 1, 1899, in Pittsburgh.

The map contains numbered regions (labeled I through VII) with different patterns, which correspond to the percentage ranges of new constructions for each area. The key in the lower left explains these patterns:

• I: Less than 3%
• II: 3% to 7.9%
• III: 8% to 12.9%
• IV: 13% to 15.9%
• V: 16% to 20.9%
• VI: 22% to 29.9%
• VII: 63%

Geographical features and neighborhoods in Pittsburgh are shown, including prominent rivers such as the Allegheny River, Monongahela River, and Ohio River. Each area is shaded or hatched based on its growth in new dwellings.

The map presents historical urban development trends and housing expansion in Pittsburgh during the late 19th and early 20th centuries.

The image is a historical map from the early 20th century, titled "The Pittsburgh Survey" under the direction of Shelby M. Harrison, dated 1908. The map illustrates the relationship between the number of new dwellings erected in Pittsburgh during the years 1899, 1900, and 1901, and the total number of buildings standing as of February 1, 1899.

The map displays the city of Pittsburgh, with the Allegheny River to the north and the Monongahela River to the south, converging to form the Ohio River. This iconic confluence is central to Pittsburgh's geography. The map is divided into several numbered zones, each marked with a pattern of lines. These numbered zones are defined in the legend on the lower left corner of the map, which correlates the zone numbers with different percentages representing the ratio of new dwellings to total buildings.

The key indicates seven different categories:

• I: Less than 3%
• II: 3% to 7.9%
• III: 8% to 12.9%
• IV: 13% to 15.9%
• V: 16% to 21.9%
• VI: 22% to 29.9%
• VII: 63%

Each category is represented by a distinct pattern filling the zones, showing varying densities of newly constructed dwellings versus the existing buildings. This map provides a visual representation of urban development in Pittsburgh at that time, highlighting areas of growth and construction. The use of patterns and the map's layout emphasize the geographic distribution of urban development during the specified period.
