Mining Standard Land Price with Tension Spline Function

Abstract

Standard land price is an economical indicator for measuring land value. In this paper, we propose to use the tension spline interpolation function to mine standard land price. First, we extend the definition of standard land price, which is based on land region composed of several neighboring land parcels with the same or similar features. Second, the regional factors that affect the standard land price are classified into the geometric features of point, line and area according to the quantitative rules. Third, a tension spline interpolation function is proposed to mine standard land price, which is determined by the influential factors. Finally, as a case study, the proposed method is applied to mine land prices for Nanning City in China. The case study shows that the proposed method is a practical and satisfactory one.
