If it is a point feature (gdbSpatialCategoryPoint), only one feature located within the point neighborhood will be selected. The radius of point neighborhood is specified by the FeaturesetCondition::ZoneWidth property.

If it is a line feature (gdbSpatialCategoryLine), all features intersected by the specified line feature will be selected.

If it is an area feature (gdbSpatialCategoryArea), a text feature (gdbSpatialCategoryText) or an image feature (gdbSpatialCategoryImage) then all features for which the percentage of area/length lying beyond the feature is not lower than the value of the FeaturesetCondition::Percentage property will be selected.

gdbFeaturesetByFeatureBuffer

All features for which the percentage of area/length lying beyond the buffer zone is not lower than the value of the FeaturesetCondition::Percentage property will be selected. The buffer zone width is specified by the FeaturesetCondition::ZoneWidth property. The buffer zone width may be negative (internal buffer zone).

gdbFeaturesetByFeatureNumbers
