Abstract

This study aims to investigate the change of developed land in three different locations along Highway 4 Road from
Phattalung to HatYai. The method involves creating a digitized grid of geographical coordinates covering the study area. The
land-use codes and plot identifiers were recorded in database tables indexed by grid coordinates. Logistic regression of land
development adjusted for spatial correlation was used to model its change over a 9-year period using land-use at the previous
survey combined with location as a determinant. The results show increasing average percentages of developed land (3% in
2000 and 5% in 2009). Land development occurred mostly in the northern location along the Pattalung to HatYai road.
