BACKGROUND
In order to meet the needs of eKadaster concept in Malaysia, CRM(Cadastre Reference Mark) was introduced as one of the control pointsthat can be used as a datum in cadastral surveying work in Malaysia.
In order to meet the requirements of eKadaster, recommended CRMcontrol points (Cadastre Reference Mark) have to meet requirement asbelow:
Distance between CRM points not less than 75 meter, At least to establish 3 CRMs, 2 CRMs needs to be visible each other, CRMs must across the lot, and Distance CRMs between 2 lots not more than 300 meter.
