As map scale decreases, resolution diminishes and feature boundaries must be smoothed, simplified, or not shown at all. For example, small areas may have to be represented as points. Distance between sample points in a lattice. Size of the smallest feature that can be represented in a surface. ArcStorm provides a restore mechanism.
Root mean square error.
A measure calculated when registering a map to a digitizer, indicating the discrepancy between known point locations and their digitized locations. The lower the RMS error, the more accurate the digitizing or transformation. See also tic . Compare with commit . Routes are based on an arc coverage and are defined as an ordered set of sections.
