Profiles from Points

Purpose 
    This tool computes the station or distance in a profile. The profile points (e.g.; from field measurements) can deviate from the “desired” profile path, and therefore, the station of each point should not be estimated rigorously as the distance from the first point in the profile.

Usage
    A typical workflow with the tool has the following three steps.

1. The user must specify the point shape file where a field specifies the profile label for each point. From that, the tool will create straight line profiles from the point coordinates by using the best fit method and save them in a new polyline shape file. A new point shape file will be also generated where the computed station value for each point are added as a column. Points with empty profile labels will be ignored.
2. The user can process in GIS (outside of the tool) the preliminary polyline shape file with the profiles. Typical processing includes flipping the line to change the profile direction, correcting start and end vertices position to make the profile perpendicular to a flow path, and adding more vertices if the profile is not a straight line.
3. The user can provide the manipulated profile polyline shape file together with the profile point shape file to recompute the stations values. In the case of profile points without an associated polyline, a new best-fit line is added, as in the step 1. Going back to step 2 may be necessary to process profile polylines as necessary.
