Description: Basic Description: The polygon feature class Fig. 6.6 Directions - Fountains Period (c. 20-1 BCE) (filename- PBMP_DIR_City_Poly_001) represents the direction of one-way streets at Pompeii between 62 and 79 CE as published in figure 6.6 of Poehler, Eric E. 2017. The Traffic Systems of Pompeii (New York: Oxford University Press). Data History: The attribute data for these features were derived from figure 6.6 and tables 6.5-6.7 of Poehler, E. The Traffic Systems of Pompeii (New York: Oxford University Press) and were produced by in-field observation and documentation by the author between 1998 and 2016. Calculations of the evidence from all street features were made as follows: “The total number of wearing patterns attested for each direction as well as the total clarity (certainty) of those interpretations is given in the first two columns of each direction [in tables 6.5 and 6.6]. Following these is the percentage of all certainty values on a street that a direction represents. For example, the total certainty value for the westbound direction of traffic on vicolo di Mercurio is 92, which is combined with the certainty values for eastbound traffic (57) to make up 61.7% of all the directional evidence on that street. For each direction the average certainty of the interpretations on that street is given as a way to assess the overall strength of the evidence supporting a particular direction and in the cases where more than one direction is attested, to support a comparison between them.” (p. 162). Directions are assigned chronologies based on the data in table 6.7. After joining the information on direction to the Streets (STR) layer, the streets were given a three meter buffer to improve visibility of the attribute data. Spatial data in this layer are based on a CAD file provided by the Soprintendenza di Pompei to Eric Poehler in 2003. The CAD file was created by digitizing the RICA Maps of Pompeii, 1984, supported by World Monuments Watch and funded by American Express. The RICA MAPs were drawn in part from aerial images taken at 820m and supplemented by on the ground survey. Inconsistencies among the features of this layer with satellite imagery or other maps of Pompeii may be the result of errors in the rectification of the original aerial images and differences projected between coordinate systems (PBMP data are in the Monte_Mario_Italy_2 projected coordinate system). On the creation of the RICA Maps, see Van der Poel, H. B., Corpus Topographicum Pompeianum, vol. IIIA. Austin, TX, 1986, XI-XIX. Symbologies: This feature class is symbolized as follows: Alternating streets (504 Periglacial); Blocked Streets (crosshatch [2pt separation]); Eastbound (70% gray); Northbound (Black); Southbound (White, black outline [0.40 line]); Two-Way streets (Mars red), Unknown (Gravel Foundation Overlay); Westbound (30% gray). There is no display transparency and scale visibility set to not above 1:40,000. Credits: These data were produced by Eric Poehler for the Pompeii Bibliography and Mapping Project after original CAD data provided by the Soprintendenza di Pompei.
