Flow direction was recorded in the field at the time of measurement using a standard compass or an electronic compass. Topologically correct Points have been checked and attributed Horizontal accuracy of point data is estimated to be within 3 centimeters Vertical accuracy of stream bottom elevations is estimated to be within 10 centimeters Water velocity data was collected using an accoustic doppler velocimeter. The horizontal location of the velocity measurements was determined using either a total station or real-time kinematic global positioning satellite system. Compass direction of flow was noted and the velocimeter was oriented into the flow for velocity measurement. Raw data was output to a text format, then used to construct Geographical Information System in a Shapefile format. 2006 Vector Entity point 730 Transverse Mercator 0.999600 -99.000000 0.000000 1640416.666667 0.000000 coordinate pair 0.000016 0.000016 survey feet North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 National Geodetic Vertical Datum of 1929 0.1 U.S. Feet Attribute values Mean sea level 0.1 feet Attribute values ofr07-1056_up_post_vel_pt point attribute table ARC/INFO ® GIS Software FID Internal feature number.
