For an adequately planned urbanization of a city like Gandhinagar, it is essential to identify potential sites for affordable housing, commercial hubs, and recreational centres based on some specific urban development criteria. These criteria have been decided based on neighborhood concepts in urban planning. We measure each criterion according to its importance, and then a certain weight of each criterion is created. Geographic Information System (GIS) and Multi-Criteria Decision Analysis (MCDA) are the standard techniques used for site suitability analysis at a macro level. For this purpose, toposheets and satellite data have been used to generate different thematic layers in ArcGIS software. GIS technology plays a vital role in the micro-level analysis or spatial planning of sectors such as Gandhinagar Municipality. A semi-automated system to perform spatial land management and a built-up area calculator have been developed by utilizing the Python script incorporated in ArcGIS. The built-up area calculator will help in identifying unauthorized construction. This research can assist the policy- makers, planning officials, bring transparency across different stakeholder groups to better understand the land parcels catering to the ongoing developmental need and future urban growth.
