Create an Anomaly Footprint Polygon Plot

Use the Target Inversion > Anomaly Polygons > Plot option (UXAPOLYPLOT GX) to plot anomaly footprint polygons in a map.

Create a Polygon Plot dialog box options

Target database	Select the target database. If no database is specified, the entries for Target group, ID channel, and mask channel will be invisible. Script Parameter:UXANALYZE.TARGETGDB2
Target group(s)	Select the target group from All, Displayed, and Selected. Default selection is Displayed. Script Parameter:UXANALYZE.LINES
ID channel	Select the ID channel from the list of channels in the target database. Script Parameter:UXANALYZE.IDCHAN
Mask channel	Select the target database mask channel to filter out specific targets. Only the targets with a mask (channel value) of 1 will be processed. If the value is set to 0 or dummy (*), the corresponding target will be ignored. If the field is left blank, no mask will be applied. Script Parameter:UXANALYZE.MASKCHAN
Polygon directory	Select the polygon folder. Script Parameter:UXANALYZE.POLYDIR
Prefix	Enter the polygon prefix. Script Parameter:UXANALYZE.PREFIX
Suffix	Enter the polygon suffix. Script Parameter:UXANALYZE.SUFFIX

Application Notes

Prefix and suffix values will limit the number of polygons found in the polygon folder. If the target database is specified, the GX will search the polygon folder based on this search pattern: [PREFIX][ID][SUFFIX].ply, where [ID] is the target ID. However, if no target database is entered, all the polygons following [PREFIX]*[SUFFIX].ply will be retrieved.

In order to avoid performance degradation, on the output map all polygons are placed in the same view group.

In order to save the edited vertices to the proper polygon file on the storage device, the polygon editing GX has to link the polygon selected on the map to the corresponding polygon file. To do so the polygon plot GX creates an intermediary Geosoft database, in which for each polygon the position of its center as well as its full path are saved. The name of this database is automatically generated to be a unique combination of the map and the polygon group names.
