Feature Description

The Reclassify Field function can assign segmented values to a new field or update existing fields based on specified field values.

Feature Entry

• Table Tab -> Edit Group -> Reclassify Button.
• Data Tab -> Data Processing Group -> Vector -> Reclassify.
• Toolbox -> Data Processing -> Vector -> Reclassify.

Parameter Description

• Operation Field: The field used for segmentation.
• New Field: Set the name for the new field.
• Type: Only supports numeric fields, with options for single or double precision.
• Segmentation Method: Provides the following segmentation methods:
  • Equal Interval: Divides data into equal intervals based on user-defined number of segments and the maximum/minimum values. Each segment has equal length.
  • Square Root Interval: Performs equidistant interval segmentation using square roots of field values. First takes square roots of all values, performs equal interval segmentation on transformed data, then squares the breakpoints to obtain original value ranges.
  • Logarithmic Interval: Similar to square root method but uses base-10 logarithms. Performs equal interval segmentation on logarithmic values, then converts breakpoints back using powers of 10.
  • Square Segment: Uses squared field values for segmentation. Squares all values first, performs equal interval segmentation, then takes square roots of breakpoints to determine original value ranges.
• Classes: Number of segments for reclassification results.
• Numerical Precision: Computational precision.
• Min: Minimum value for reassigned segments.
• Max: Maximum value for reassigned segments.
