The study of High-Resolution Airborne LiDAR Data to delineate the landslide

susceptibility area based on DTM Parameters, Land use and Vegetation cover will

conduct in following phases. i. Acquisition of Satellite Digital Stereo Images/Digital

Topographic Map/Aerial photographs. This process involves the acquisition of High-

Resolution Airborne LiDAR Data from Bahagian Kejuruteraan Cerun, JKR Malaysia,

Satellite digital images from Malaysian Remote Sensing Agency, topographic map and

aerial photographic from Sarawak Land Survey Department. ii. Desktop Studies

Desktop study involves literature reviews of related information regarding vegetation

cover, landslide hazard mapping, satellite image interpretation and other related

geological information such as landslides, erosion, and areas of instability, geology

and geological structures. Aerial photographs and satellite imagery were also used to

gather information as above as well as the pre writing of Table of Content of the

research paper. iii. Processing of High-Resolution Airborne LiDAR Data, Satellite

Images and Aerial Photographs. The geological structures such as lineament, relict of

landslides and the accumulation of colluvium will be derive from a high resolution DEM

and multispectral satellite images. These information are based on the study of

vegetation cover of the study area. Other information on vegetation cover and landuse

will be extracted from aerial photographs and literatures. Attempt be made to verify the

accuracy of the images before analyses being carried out. iv Field Investigations The

purpose of the fieldwork is to locate and ascertain the general morphology and

engineering geology of the area besides identification of forest types, forest structures

and soil types. From this viewpoint, the features such as the geological structures,

distribution of colluviums, types of vegetation and land use that were demarcated on

the base map are then compare with the initially being draft from the desktop studies

based on the aerial photographs for accuracy. v. Analysis of data Field data such as

forest types, land use, physical characteristic of soil and geological information and

data from satellite images will be merge for analysing to find out the relationship

between geohazard potential and the distribution of specific vegetation cover. vi

Preparation of maps and texts The preparation of maps are based on the findings of

the image interpretation, how is the analysis being carried out and what are the

formulae used. The framework of the report writing will be tabled and presented before

being finalised. The findings of the research will be discuss in details together with the

recommendation in the last chapter.
