In the process of planning the landuse of an area, town planners require basic information such as the geology, topography, landform and zones which are potentially unstable. Terrain Classification Map and its derivative thematic maps such as Landform, Erosion, Physical Constraints, Engineering Geology and Construction Suitability Maps serve as useful tools for such a purpose. Geological terrain mapping is carried out based on the evaluation of four attributes, namely, slope gradient attribute, terrain or morphology attribute, activity attribute and the erosion and instability attribute. To prepare the various derivative maps, a GIS system (using Arc Info or Arc View software) is used to analyse data from the four attributes. Geological terrain mapping was conducted in the Cameron Highlands and the various derivative maps produced from the mapping programme are used in the planning and approval of development projects in the area. Abstrak: Dalam proses perancangan gunatanah bagi sesuatu kawasan, perancang bandar memerlukan maklumat asas seperti geologi, topografi, bentuk muka bumi and zon-zon yang tidak stabil. Peta pengelasan terain and peta-peta tematik seperti bentuk muka bumi, hakisan, kekangan fizikal, geologi kejuruteraan dan kesesuaian pembangunan dapat berfungsi sebagai alat untuk mencapai tujuan berkenaan. Pemetaan geologi terain yang dijalankan adalah berasaskan kepada penilaian empat atribut iaitu kecerunan cerun, terain atau morfologi, aktiviti yang dijalankan serta hakisan dan ketidakstabilan cerun. Untuk menyediakan berbagai peta tematik, sistem GIS (menggunakan perisian 'Arc Info' atau 'Arc View') digunakan untuk menganalisa data dari keempat-empat atribut tersebut. Pemetaan geologi terain telah dilakukan di Cameron Highlands dan berbagai peta tematik yang telah dihasilkan dari program pemetaan ini sedang digunakan dalam perancangan dan kelulusan projek-projek pembangunan di kawasan berkenaan.
