The 2016 LiDAR data had a much higher point density (4 points per m2) than previous versions, which should result in more accurate flow paths. The layer was generated using the D8 flow model algorithm in ArcGIS. </SPAN></SPAN></P><P STYLE="font-style:italic;margin:0 0 11 0;"><SPAN><SPAN>Creation date</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Finalised in July 2019</SPAN></SPAN></P><P STYLE="font-style:italic;margin:0 0 11 0;"><SPAN><SPAN>Update cycle</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Whenever Auckland Council’s LiDAR has been updated, if possible.</SPAN></SPAN></P><P STYLE="font-style:italic;margin:0 0 11 0;"><SPAN><SPAN>Contact Person</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Mahesh Patel</SPAN></SPAN></P><P STYLE="font-style:italic;margin:0 0 11 0;"><SPAN><SPAN>Contact Position</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN>Senior Healthy Waters Specialist</SPAN></P><P><SPAN /></P></DIV></DIV></DIV>
