The present vertical datums in Sabah and Sarawak (East Malaysia) are based upon various tide gauge measurements of mean sea level over certain period defined locally, are manifested by a physical framework of vertical reference point i.e benchmarks. An effort to establish a unified vertical network in Sabah and Sarawak has undergone very tedious survey operation, lack of access routes to connect levelling network due to geographical setting constraint, and it is too costly to be fully implemented. This paper discussed the current status of vertical datum in East Malaysia as well as the concept of realizing new vertical datum based on gravimetric geoid model.

Human-Elephant Conflict (HEC) has been identified as one of the major threats to wild elephants throughouttheirrange in thirteen countries,including Malaysia. With development encroaching onthe elephant’s natural territories, the number of HEC cases has increased. The aim of this study is to focus on developing a framework for elephant rerouting and causewaysusing geomatics technology and 3D geo-visualizationas a strategy to conserve elephantsin a sustainable wayfor Taman Negara Rompin.The framework wasused to propose alternative pathwaysbased on rational model. As a result of the framework, four main elementsstrongly highlighted in the rerouting framework are elephant diet’s sources, tracking trails, fencing and deterrents,and the corridor monitoring. These elements are important for rerouting and causeway of the elephant. With the integration of geographical information system,the knowledgeneeded toprotect elephants from HECcan be enhanced.
