I. Introduction
With expansion of electrical distribution network even to remote corners in any country, the spatial nature of the network affects the planning process. Usually the network parameters such as resistance and inductance also depend on length of conductor and their configuration for catering power to different consumers. Thus in distribution system modeling based on spatial data along with consumer demand seems to be promising for real-time applications such as consumer indexing for tariff as well as planning purposes. Spatial data, also known as geospatial data or geographic information, is the information that identifies the geographic location of features and boundaries on earth, such as natural or constructed features, oceans, and more. It is usually stored as coordinates and topology, and is data that can be mapped. It is often accessed, manipulated or analyzed through GIS [1].
