West Philadelphia Topography - 5ft contours

The topography maps show contour lines at one, two, five, and ten-foot intervals. These lines are based on approximately four thousand street corner spot elevations digitized from Philadelphia City Streets Department and Water Department maps. They were interpolated using a road alignment and terrain modeling software called InRoads. Shown here is the 5ft contour interval map.
