Metode cellular automata telah digunakan untuk memodelkan penyebaran kebakaran hutan dan lahan di Kabupaten Mempawah. Data yang digunakan dalam penelitian ini adalah data tutupan lahan Provinsi Kalimantan Barat dari citra satelit tahun 2012 dan peta yang memuat fire history tahun 2013 di Kabupaten Mempawah. Tahap pengolahan data dimulai dengan mengelompokkan data vegetasi ke dalam 2 kelompok vegetasi yaitu: vegetasi basah dan vegetasi kering. Peta yang telah disimpan sebelumnya dalam format ".jpg" dipotong ke dalam ukuran 250 x 250 piksel. Pemodelan kebakaran hutan dan lahan dengan metode cellular automata menggunakan geometri sel segi empat 2 dimensi. Jenis tetangga sel utama yang digunakan adalah jenis moore neighborhood (8 sel tetangga). Gambar hasil pemodelan dan data pembanding kemudian diolah melalui tahap grayscale dan thresholding, lalu kedua gambar diuji untuk diperoleh nilai koefisien korelasinya. Nilai koefisien korelasi tertinggi dari pengujian gambar hasil pemodelan terhadap 49 koordinat titik api yang berbeda sebesar 0,6850 (korelasi kuat) pada koordinat titik api (100,130). Hasil penelitian menunjukan bahwa metode cellular automata dapat digunakan untuk memodelkan penyebaran kebakaran hutan dan lahan di Kabupaten Mempawah dengan baik.
