March 2011 Mapping in Memphis: University Students Help Map City Infrastructure By Brian Waldron November 2010 A Road Map for Mapping Roads By L. Scott Tillett March 2010 Saving Lives: Pipeline Improvements Bring Clean Water to Impoverished Areas By Angus W. Stocking 20 G E O W O R L D / N O V E M B E R 2 O 1 0 24 BY BRIAN WALDRON Mapping in Memphis University Students Help Map City Infrastructure T he land on which Memphis, Tenn., resides first was occupied by Native American Indians. It was ceded by the Chickasaw Indians in 1818, and Memphis was founded the following year by General (and later President) Andrew Jackson, General James Winchester and Judge John Overton. Memphis continued to grow in size and population through the Civil War. Before, during and after the Civil War, Memphians were inflicted with numerous yellow- fever epidemics (1828, 1855, 1867, 1873 and 1879). Due to the high number of yellow-fever deaths and the large number of citizens fleeing the city, Memphis' char- ter was revoked in 1879, becoming a taxing district. In 1880, the death rate was 4 percent, and Memphis was able to thwart future epidemics owing to the dis- covery of a seemingly endless artesian groundwater supply in 1886. This artesian water supply provided clean drinking water and allowed sanitary waste to be readily removed from the city proper. Construction of the sanitary sewer and stormwater systems also began during the 1880s. G E O W O R L D / M A R C H 2 O 1 1 Memphis regained its charter in 1893, and the population nearly quadrupled by 1902. More than 150 miles of sanitary sewer and stormwater lines were laid, and the death rate had dropped to 1.6 percent. Jumping ahead one and a quarter centuries, Memphis now is one of the 20 largest U.S. cities in terms of population and area. During the last 125 years, the expansion of Memphis' sanitary sewer and stormwater network resulted in separate systems comprised of nearly 3,600 miles of sanitary sewer and 3,950 miles of stormwater lines.

"But these men are retiring, and we now need to begin the conversion of our paper records to a system that is more compat- ible with the new generation of workers who are more attuned to computer systems." The city of Memphis partnered with the University Mapping a Century-Old Infrastructure Mapping these systems and recording the mainte- nance on existing structures historically was accom- plished on paper—45,750 documents to be exact, including a few dating back to the late 1800s that were scribed on linen. "In the past, we relied on the corporate memories of the 'old hands' in maintenance, and this worked pretty well," says Ron Kirby, administrator of Environmental A Road Map for Mapping Roads of Memphis' Center for Partnerships in GIS (CPGIS) to digitize the systems. CPGIS acts as a university portal, connecting outside entities seeking GIS solutions to the expertise available on campus. CPGIS promotes engaged scholarship by hiring students to work on projects, thereby increasing their knowledge in GIS and improving their marketability upon graduation. "The partnership with CPGIS has been extremely beneficial for the city," says Della Adams, enterprise GIS manager for Memphis. "The city has for several years sought ways to capture this infrastructure data in an efficient and cost-effective way. CPGIS provided this service. The city was able to leverage the high- level expertise of a university center, leading-edge GIS technology and an abundant pool of qualified student resources to map our infrastructure in a timely and cost-effective manner. We also are pleased to be able to engage our local students, providing meaningful real-world work experience." A federal agency brings geospatial and modeling tools to bear on highway analysis. The Memphis stormwater infrastructure was mapped in a GIS and overlaid on high-resolution aerial photography. M A R C H 2 O 1 1 / W W W . G E O P L A C E .
