Adds attributes about the banks of each cross section in a dataframe of cross section points Function adds "bottom", "left_bank", "right_bank" columns that are the Z values of the "lowest" bottom point, and the "highest" left and right bank Z values, respectively. If there are And also a "valid_banks" column is added that is TRUE if the hy_id/cs_id set of cross section point has at least 1 bottom point with at least 1 left bank point AND 1 right bank point that are above the lowest "bottom" point.add_bank_attributes

Add relief attributes to a dataframe of cross sections points Given a set of cross section points (derived from hydrofabric3D::cross_section_pts() and hydrofabric3D::classify_points()) add a "has_relief" logical value to data. The "has_relief" value is indicating whether a cross section "has relief". Relief is determined by checking each set of cross section points have a left OR right bank that has a depth difference from the bottom that isgreater than or equal to a percentage of the cross section length (e.g. Assuming a 'pct_of_length_for_relief' of 0.01 (1%) of a 100m cross section would have a relief depth threshold of 1m)add_relief

Selectively removes intersecting transect lines Attempts to remove transects intersecting other transects by first removing transects that interesect the most other transects, then re checking intersection condition, and doing this until there are no multi intersections this gives the benefit of removing a transect line that intersects many other transects, potentially leaving those other transects with no extraneous intersections ONCE the MULTI intersecting transect is removedrm_multi_intersects
