| Kajian dijalankan untuk memetakan kepadatan penduduk negeri Pulau Pinang menerusi aplikasi kaedah koroplet dan kaedah dasimetrik. Data banci penduduk pada tahun 2010 telah digunakan dalam kajian ini. Data banci penduduk negeri Pulau Pinang mengikut mukim, iaitu 22 buah mukim bagi Seberang Perai Tengah, 16 buah mukim bagi Seberang Perai Utara dan Seberang Perai Selatan, 7 buah mukim bagi Timur Laut dan 22 buah mukim bagi Barat Daya. Guna tanah bagi negeri Pulau Pinang juga merupakan salah satu data input penting bagi kaedah dasimetrik. Oleh itu, guna tanah di negeri Pulau Pinang telah dihasilkan menerusi interpretasi imej satelit Landsat tahun 2010 kepada lapan jenis guna tanah iaitu badan air, hutan, kelapa sawit, rekreasi, padi, bakau, tepu bina dan tanah lapang. Pemetaan kepadatan penduduk menggunakan kaedah koroplet dan kaedah dasimetrik dilaksanakan dan didapati bahawa kaedah dasimetrik dilihat lebih efektif dalam menggambarkan keadaan yang sebenar di lapangan (negeri Pulau Pinang) berbanding dengan kaedah koroplet yang hanya diwakili oleh satu warna sahaja dalam setiap poligon atau mukim yang terlibat, iaitu warna yang gelap (tinggi kepadatan penduduk) dan warna yang pudar (rendah kepadatan penduduk). Hasil kaedah pemetaan dasimetrik pula menunjukkan taburan penduduk adalah tidak sekata walaupun dalam satu mukim atau poligon yang sama. Secara umumnya, peta dasimetrik menghasilkan taburan spatial kepadatan penduduk mengikut nilai kesesuaian menghuni berdasarkan taburan guna tanah. |
