Boundaries for Pittsburgh City Council

This data shows the attendance boundaries used to assign students to feeder pattern schools based on their place of residence. These boundaries were adopted for the 2012-13 school year by the Pittsburgh Public Schools. The boundaries were drawn to align with major roads, neighborhood boundaries, and natural features. Efforts were also made to enable all students within an elementary school to move to the same middle school, and allow all students in a middle school to transition to the same high school.

This Polygon Feature Class is of the City of Kingston former Municipal Boundary. The boundaries were for the City of Kingston, Kingston Twp, Pittsburgh Twp prior to amalgamation in 1998. This data is used for Map Presentations, Web Map Applications and General Analysis.

About the G.M. Hopkins Maps History and Background of the Maps Maps produced by the G.M. Hopkins Company have made a lasting impression on the boundaries of many American cities. Between 1870 and 1940, the company produced over 175 atlases and real estate plat maps that primarily covered the Eastern sea board, including cities, counties, and townships in 18 different states and the District of Columbia. In the early years, the company produced county atlases, but gradually focused on city plans and atlases. They were among the first publishers to create a cadastral atlas, a cross between a fire insurance plat and a county atlas prevalent in the 1860s-1870s. These real estate or land ownership maps (also known as plat maps) not only depict property owners, but show lot and block numbers, dimensions, street widths, and other buildings and landmarks, including churches, cemeteries, mills, schools, roads, railroads, lakes, ponds, rivers, and streams. Originally named the G.M. Hopkins and Company, the map-making business was jointly founded in 1865 in Philadelphia, Pa., by the Hopkins brothers, G.M. and Henry. The true identity of G.M. Hopkins remains somewhat of a mystery even today. “G.M.” either stands for Griffith Morgan or George Morgan. There are three different possibilities for the confusion over his identity. “Either the compilers of the earlier [city] directories were negligent; G.M. Hopkins changed his first name; or there were two G.M. Hopkins (father and son) working for the same firm” (Moak, Jefferson M. Philadelphia Mapmakers. Philadelphia: Shackamaxon Society, 1976, p. 258). http://digital.library.pitt.edu/abouthp/#hopkins McKeesport from the original Sanborn maps from 1889.
