Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>The county-wide GIS street centerlines data were originally captured from panchromatic orthophotography flown by Merrick & Company in 2000. The road centerline was generated from the “apparent centerline” to display an interconnected road network, and as such, does not display physical road pavement, road width or shoulder dimensions. Additional spatial adjustments were made to the layer from color-infrared orthophotography and LiDAR data flown in 2013. In particular, the physical location of some street segments in the 2000 imagery were often obscured by continuous canopy. Where needed, the original street centerline features were moved to more closely align to the physical locations shown in the LiDAR. Street attributes such as left and right from/to address range, street name, and type, were conflated from US Census TIGER data and augmented by street attributes from the County’s 911 dispatch system. Subsequently staff engaged in an extensive QC process to correct errors in the conflation process. This information was provided to the US Census in 2005 and incorporated into the Census US TIGER data set for the 2010 decennial census.</SPAN></SPAN></P></DIV></DIV></DIV>
