Cross sections are measured locations along a branch, where a surveyed cross section is located. This data type includes a unique identifier, the branchID it is associated with, and the chainage or location along the branch. Cross sections are measured locations along a branch, where a surveyed cross section is located. This data type includes a unique identifier, the branchID it is associated with, and the chainage or location along the branch. Label of cross section - this links to the branch and also to the longitudinal profile Geographic coordinate (Easting) of cross section Geographic coordinate (Northing) of cross section Coordinate of the left bank point (cross section coordinate) Coordinate of the right bank point (cross section coordinate) Coordinate of the thalweg point (cross section coordinate) Elevation of the left bank point Elevation of the right bank point Each cross section can hold an (unlimited) umber of X and Z point representing the surveyed location and elevation along the cross section and two attributes describing the resistance and mark use this field as a notebook to add comments, suggestions description of data entered etc. Each cross section can hold an (unlimited) umber of X and Z point representing the surveyed location and elevation along the cross section and two attributes describing the resistance and mark cross section point distance co-ordinate cross section point elevation This assigns roughness to each point in the cross section.
