It is sometimes necessary to calculate the total length of lines within a polygon to perform spatial analysis for an area in a map. For example, the extent of the rivers for water quality analysis, the length of the rivers within an area, or the distance between rivers for gold exploration...

• When I say that one symbol is twice as large as another, I mean itsareais twice as large, not its point size, or diameter, or circumference. Specifically, the square root of the data value will be used as the radius to calculate the area of a circle symbol. ...
