ABSTRAK

Pemetaan Geotapak untuk Pulau Ular telah dijalankan menggunakan kaedah penderiaan jauh yang melibatkan data peta topografi, gambar udara, imej satelit serta gambar yang diambil menggunakan dron. Analisis penderiaan jauh ini menghasilkan peta geomorfologi. Langkah seterusnya adalah melakukan kerja lapangan yang akhirnya menghasilkan satu peta geologi. Cerapan lapangan telah dapat mengenal pasti fitur geologi dan landskap yang penting dan menarik, dan sebanyak 10 lokaliti atau tapak telah dikenal pasti mempunyai fitur geologi atau landskap yang penting kepada pemahaman sejarah pembentukan pulau ini, antaranya kepelbagaian jenis batuan, fosil, struktur sedimen, struktur tektonik dan fitur hakisan. Berdasarkan semua maklumat yang diperoleh ini, peta geotapak Pulau Ular telah dibangunkan dan boleh digunakan dalam membuat perancangan pemuliharaan dan pembangunan geopelancongan.

Kata kunci: Kepelbagaian geologi; pemetaan geotapak

ABSTRACT

Geosite mapping of Pulau Ular was conducted using remote sensing which includes data from topographic maps, aerial photograph, and satellite image as well as a photographs made by a drone. A geomorphological map was generated by remote sensing analysis. The next step was field work/observation to produce a geological map. Field observation identified 10 sites and localities with important and significant geological and landscape features for an understanding of the geological formation of this island such as rock, fossil, sedimentary structure, tectonic structure and erosion feature. Using all this information a geosite map of Pulau Ular was constructed and can be used in conservation planning and geotourism development.

Keywords: Geodiversity; geosite mapping
