CURRENT STANDINGS ( general issues) q Paper based information q Disintegration of information (drawings and textual are not together) q No uniform standards for the capturing data q No standardized software q Long turnaround time to capture and maintain CAD-based q Non proper definition and procedures for attributes input q No proper updating of information q Planning and maintenance not based on proper analysis

OBJECTIVES OF GIS 1. Makes information more accessible (digital environment) 2. Identify spatial (locational) based assets 3. Improve Customer service 4. Integrated data management and decision support system

POSSIBLE SOLUTION WITH GIS q Digital information q Integration of information (Pipeline, Assets, billing, etc ) q Standards procedures for the capturing data q Short turnaround time to update information q Easier and consistent updating of information q Planning and maintenance is based on proper analysis
