VI. TEKNIS EVALUASI LAHAN DENGAN SIG

• Teknologi SIG dapat mempermudah proses evaluasi lahan

• Menterjemahkan data penggunaan lahan, kemampuan / kesesuaian lahan ke

bentuk digital (sesuai tipe SIG)

• Proses standarisasi dan kategorisasi

• Proses tumpang-tindih

• Proses ekstrasi dan pemetaan dan analisis
