The objective of this research was to evaluate agricultural potential land class (APLC) by geographic information system based on 4 agricultural potential land criteria including elevation, soil order, irrigation system and soil moisture regime. This research used application of geographic information system for analyzing and developing spatial model to classify 6 APLC orders: APLC 1 (commercial farming, CF), APLC 2 (sufficient farming, SF), APLC 3 (urban and industrials, U&I), APLC 4 (biomass plant, BP), APLC 5 (economic forest, EF) and APLC 6 (natural conserve, NC). The results showed that the agricultural potential land classes of Phetchaburi province were APLC 6, APLC 4, APLC 5, APLC 2, APLC 3 and APLC 1, with 1.564 (40.55 %), 0.759 (19.68 %), 0.596 (15.45 %), 0.405 (10.50 %), 0.339 (8.79 %) and 0.194 (5.03 %) million rais, respectively.
