Data Source History: The data was received from ESRI as an Arc/Info coverage in UTM projection, NAD27. Jonathan Lowe, Local Knowledge Consulting, converted the layer into Cal Stateplane, NAD83, units feet, using Arc/Info's projection utility and two custom AML's called "utm2spc.aml" and "nad2783.aml." Upon the adoption of the "streets" coverage and the digital orthophoto as Oakland's standard for coordinate accuracy, Jonathan corrected the council coverage using the arc/info "adjust" command with parameters based upon the node-to-node links established during the tiger-roads conflation process. Jake Schweitzer, In Situ Mapping, made further manual adjustments to the layer to match the improvements in accuracy of the streets and city limits layers.
