The Mapping coverage is a generic coverage used for building feature objects for conversion to a scatter set.

General Mapping Options

When creating a new Mapping coverage from the New Coverages dialog, the General Mapping Options dialog will appear.

The General Mapping Options dialog

Mapping Arc Attributes Dialog

Arc Attributes dialog

The Arc Attributes dialog is used to set the attributes for feature arcs in a Mapping type coverage. These attributes will set parameters for the arc conversion with generating a scatter set from the coverage. Attributes that can be specified for each arc include:

  • Generic Arc
  • Hydraulic Connection Arc
  • Active Edge Arc
  • Coastline Arc

The dialog is reached by double-clicking on an arc with the Select Feature Arc tool with the Mapping type coverage active.

Mapping Polygon Attributes Dialog

Polygon Attributes dialog

The Polygon Attributes dialog is used to set the attributes for feature polygons in a Mapping type coverage. The assigned attributes will set parameters for how the polygon will be converted when the coverage is converted to a scatter set. Attributes that can be specified for each polygon include:

  • Extrapolation Type
    • Zero extrapolation
    • Interpolation
    • Standard extrapolation
    • Hydraulic connection extrapolation
    • Coastline extrapolation

The dialog is reached by double-clicking on a polygon with the Select Feature Poygon tool with the Mapping type coverage active.
