Elevation Contours of the Bathymetry near Shorty's Island and Myrtle Bend, Koootenai River near Bonners Ferry, ID, 2010

The elevation contour data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The contours were created from a surface raster (also referred to as digital elevation model) of the bathymetry data and displays the elevation in 1 meter intervals for the below water areas.

本高程等值线数据基于2010年6月3日至2010年6月19日、历时约一个月的野外勘测所获蜿蜒河段水深测量（bathymetry）数据生成。该子集数据的覆盖范围为上游河流公里标228至237河段。类似的水深测量与数据处理方法可参考Fosness（2013）的相关研究。本等值线由水深数据的表面栅格（亦称为数字高程模型（digital elevation model））生成，以1米为间隔展示水下区域的高程信息。
