This routine provides the ability to analyze, search and represent data generated by Polygon Processor.
A query is defined based on the parameter name (original layer name) and a condition. Several expressions may be combined using ANDs or ORs to produce a complex query. To verify the query, click on the Calculate button and the number of matching polygons will be reported.
The values stored in the polygon areas are text strings from the original text labels used in Polygon Processor. The expressions are evaluated on these text strings, but the program will compare numbers embedded into strings as numbers:
A12B < A50B
A12B > A5B
A12B < ABC
123 < A123
5-ABC < 13-ABC
A complete report on all polygons matching the specified query may be obtained by clicking on the Report button. All the parameters, along with the areas and polyline handles, are shown in the standard report formatter dialog. The Hatch button applies various hatches to the polygons matching separate queries to create a visual representation of the data. To remove unwanted polygons, i.e. ones which do not contain a combination of required parameters, you may click on the Delete button. This removes processed closed polylines from the POLYPROC layer. To pre-select queried polygons to be used in some other command by means of "previous selection set", use the Select button.
