Specific examples of conditionsfrom SEE-IT CTDB Spiral 3 analysis

• Databases often contain topological holes or other problems that visual

inspection does not (or can not) reveal.

• • Some of the problems can be seen using the JSAF cross section tool (steep polygons, for instance). Other problems confuse even the JSAF cross section tool (often a spike is shown by this tool when trying to create a cross section across a topological hole, even though a spike does not really exist).

• Problems that cannot be identified or are incorrectly described using JSAF

are particularly troublesome and irritating.

• SEE-IT is able to quickly and accurately locate all problems of interest.

• The following 3 slides show examples of specific problems located using

SEE-IT. Correlated snapshots from SEE-IT, JSAF PVD, JSAF cross

section tool, and/or out-the-window views are shown.
