Purpose

The Polygon Attribute Reaggregation System (PARS) allows the transfer of data from one polygon coverage to another. This document describes the concepts used in PARS, and the operating procedures.

• Introduction to PARS
  • Types of polygon interpolation
• Different types of data
  • Interpolating NOMINAL and ORDINAL data
  • Interpolating MEASURE data
  • Interpolating COUNT data
• Special cases
  • Dealing with classified data
  • Dealing with non-areal proportions
  • Using Source and target masks
  • Identifying abandoned polygons
• Program documentation
  • Installing PARS
  • Operating instructions
  • PARS programs

PARS was developed for CanSIS in cooperation with Polestar Geomatics. PARS is currently implemented in ARC/INFO. Source: Ballard and Schut, 1995
