However, in such a condition where majority of people leave in rural area and are provided with the least infrastructure facilities, creates a regional imbalance in development, causing shift in population from rural to urban areas. Hence administrators or decision-makers require an efficient GIS based tool which will assist them to get the updated scenario of the region. Recently after the creation of Jharkhand as 28th state, it faces a number of challenges in the path of development. One of the main causes is absence of accurate digital data in the form of maps. The data generated by various state government departments such as Education, Health, PWD e.t.c are enormous but poorly maintained, particularly the spatial data shows the maximum inaccuracy. The present study emphasises the power of GIS technology which will help the state government of Jharkhand to better understand and evaluate spatial data by creating graphic displays using information stored in the database .As GIS does more than just display the data; it enables the user to dynamically analyse and update the information linked to those locations spatially and can further strengthen the e-governance. Ranchi district was taken as a case study covering all the 20 blocks with 2154 villages. The administrative maps were digitised and non-spatial attribute data, prepared on MS-Excel, were incorporated to each of the villages in spatial data. In the present study two prime parameter – health end education were taken as a model to demonstrate the GIS based e-governance. Similarly other amenities can also be linked and a holistic analysis of the regional development can be found out. The purpose of this study is to locate existing health and education facilities and indicate upgradation /new creation of such facilities require as per the norms. An interface was customised where the user can query on the datasets to retrieve tabular and spatial information.ArcInfo8.01 software were used for creating maps (to the scale) and Arcview3.2a for creating the GIS based information system. Provision is made for hosting the maps on the Internet in such a way clients can view the information query using Arcexplorer. It is concluded that a state like Jharkhand which has immense potential of development and has maximum tribal population residing in rural area urgently needs a GIS based e-governance system such that it will help the government in planning, implementation and monitoring of various projects for development in different fields at much faster rate which in turn will make the state technologically more developed.
