Spatio-Temporal Visualization of Land Price Change in the Greater Yogyakarta City, Java, Indonesia

Abstract

This paper analyses changes in the land distributions, patterns, prices and the causal factors affecting land price in the greater Yogyakarta city, Java, Indonesia in 1996-2011. Field survey in hundreds of sample points with a sample size of 100x100 square meter have been carried out to identify factors affecting changes in land price. In addition, reports from the government offices were used to assist the data analyses. Furthermore, by using combination between visualization model based on isoline symbol combined with isopleth symbol and multiple linear regression analysis, this study was able to visualize the changes in land price of the study area for past and future conditions. The results showed that the distance to city centre and the distance to socio-economic activities were identified as the most significant factors affecting land price. In addition, this study found that the sub-urban in the study area was currently transforming into urban area affecting changes in the land price pattern. It was also observed that in the past an increase trend of land price was toward the north-eastern area, but currently began to shift towards south-western area. Finally, it was predicted that the south-western part of the greater Yogyakarta will be the target for land buyer in the near future for which several measures are required to control an increase in the land price.
