Database of OCFCD-maintained drainage facilities linked by reach number to Flood Programs Support Deficiency Study (AKM, 2010). This data can be viewed through GeoResearch 3.0 application.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The original linework was directly converted from MicroStation CAD files without much corrections, therefore the database undergoes continual editing of channel alignments to be spatially accurate when overlaid with OC Survey parcel landbase. Where needed, as-built plan sheets were georeferenced and channel alignments traced from the sheets. The "Data of Data" field indicates when the channel segment was corrected or otherwise confirmed to be accurate. </SPAN></P></DIV></DIV></DIV>
