The empirical approach to strengthen coordinated cadastral database accuracy

Abstract The coordinated cadastral database in Malaysia is known as National Digital Cadastral Database (NDCDB) with an expected accuracy of ±10cm rural and ±5cm urban area. Till date, there are approximately 7.8 million land parcels 22 boundary markers the NDCDB for whole Peninsular Federal Territory Labuan covering total area 132,183 km 2 . Since 2010, block adjustment has been carried out continuously without giving prime concern to eliminate gross errors adjustment’s input data. This approach aims propose a methodology improve positional existing through utilisation current eKadaster application. A comprehensive investigation office field processes prove efficiency introduced. was focused on East Coast Rail Link (ECRL) right way (ROW) survey from Dungun Besut where displacement 1 6 meters relative coordinates, shown Land Acquisition (LA) Plan, have identified. Areas involved coded Block T10701, T1100101 T1100102 which located Lubuk Kawah Pelagat Sub-districts, state Terengganu. Positional after further verified by comparing coordinates randomly picked ground proofing points using Real-Time Kinematic (RTK) observation. will determine Root Mean Square Error (RMSE) respective based actual observations adjusted coordinate values. With that, it can be concluded that proposed reasonably practical capable strengthen used Malaysia.
