Geological Terrain Mapping using Geographic Information System (GIS) and Drone Photogrammetry

The research area was conducted within the Bukit Persekutuan, Kuala Lumpur, and it located at latitude 3° 8'32.93"N longitude 101°40'32.80"E. researcher carried out geological terrain mapping to evaluate in accordance with classification attributes of each thematic map produced, namely, Terrain map, slope gradient erosion, instability as well construction suitability map. occurrence landslide events becomes a major contributing factor thoroughly conducting an investigation by field analysing using Geographic Information System (GIS) technology. application drone photogrammetry images play essential role analyze process data, thus, generate maps. indicates that about 79.11% overall not appreciable 8.58% contribute 11.00% recent general instability, 2.97% represent event. for development illustrated Class I (23.40), II (36.37%), III (26.39%), IV (15.50%) where can be referred system, high class I, moderate II, low suitable IV.
