Abstract
The objective of this paper is to analyse the various issues involved in the Urban GIS application development, and how it meets the timely requirements of the various local urban authorities. The various issues discussed in this paper are, the process of urban GIS application development – starting from the collection of the data or acquisition of data, and the various methods employed, data base development, GIS development and the customized application development etc. The analysis of the various issues and the requirements of the local authorities leads to the recommendations on the need of the hour for urban GIS application development. The paper finally concludes with the results of the analysis, and the broad recommendations or guidelines for urban GIS application development.

2. Introduction
Urban GIS application, is an essential decision support system for any local Urban authority, which handles complex urban issues varies from road development, solid waste management, drainage, hospitals, the property tax collection and the tax assessment etc. All of the various urban issues, the urban authorities has to involve in the planning, development and monitoring of the various infrastructure facilities.

The foremost need of these authorities is to have the scientifically prepared digital basemap, which showing the existing infrastructure facilities like roads, drains, the built up areas and the waterbodies etc. These basemaps also helps them in knowing the extent of their jurisdiction and the various divisions like zones, ranges and wards etc for day to day monitoring and development works. The other requirements of the local authorities is the detailed digital maps of the various local areas/wards which is showing the properties/buildings, utilities etc. These detailed digital maps (database), which many of the authorities, not affordable in terms of the cost and also the time required for development of these digital databases also enormous. So for these local authorities the essential requirement like the development of GIS application has to be affordable and time bound solutions. The GIS based decision support systems development has to address these two major issues of cost and time of the local authorities.

3. The process of urban GIS application development
There are three phases involved in this kind of project, first phase involves the study of the existing system and analysis to arrive at the objectives of the project, the second phase involves data analysis, data collection, database design and development and third phase involves the implementation aspects like application development, customization and training etc. The first phase is the study of existing system – (local authorities) of data available with the local authority. This step must be given more importance to make use of the available data with the authority.

The second phase involves the data analysis, data collection and database development. Data needs assessment has to be dome extensively, in terms of what level of details, accuracy and to be precise-what is needed at this point of time and meets the immediate requirements of the local authority. This stage of the project is very crucial, in terms of the cost & time since 50% of the total project cost and time will be spent on this stage of development. The suitable data for this kind of project has to assessed based on the affordable time a cost by the local authority. The comparative analysis of the various data & process for the large scale mapping & GIS projects as explained in the table1 (enclosed table)
