Methods:
A successful GIS operates according to a well-designed plan and business rules that are the models and operating practices unique to every organization.
GIS gives information such as the location (example for where is the customer, line, cable, DTR, feeder, substation, etc.?), topology, that describes the spatial relationships among adjacent features (e.g., what land use is adjacent to each of these customers, lines, DTRs, feeders, cables, substations, etc?), attributes (e.g., what are the capacity, numbers, voltages, crossings, etc.?), dimensions (e.g., what is the area and perimeter?), etc. GIS organizes geographic data within a series of thematic layers and tables. It links locational (spatial) and database (tabular) information and enables the user to relationships, visualize patterns and trends.
