Maintenance descriptionGIS technicians are creating new features by digiting channel improvement lines from improvement or construction plans via ArcMap. Derived attributes are created through a model process programmed by Elisabeth vanderLeeuw. That process also converts the feature class to shape file format which is copied to gislib.

Trigger: Feature class edits cause a database trigger to do post-edit processing, including calculating the URL field value from other feature fields.
