These contours were generated as a cartographic product for use in map production and spatial analyses. While they conform well with the base data from which they were generated, no effort was made to guarantee a specific level of contour accuracy. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>These contours were generated primarily from a 2014 LiDAR-based DEM dataset acquired by Oregon Metro. Historical LiDAR-based DEM data were used to augment the 2014 DEM as necessary to provide complete coverage for the Tualatin Watershed. The general contour generation process was: 1) Apply evenly weighted 5x5 smoothing to DEM via convolution function 2) Generate contours from smoothed DEM using gdal_contour utility 3) Split contours into 1000 ft segments 4) Remove contours with circumference less than 100 ft 5) Build geometry and attribute indices.</SPAN></P></DIV></DIV></DIV> |
