The document discusses the emerging trends in geographic information systems (GIS) for real estate development. It notes that foreign investment in real estate has increased demand for land information but this information is dispersed across different government departments without standardization. GIS can help integrate this information on land ownership status, infrastructure access, zoning, and utilities. It also discusses how GIS needs are shifting from 2D parcel maps to 3D/4D models with accurate boundaries and property layers to better support complex urban planning activities. Regularly updating integrated regional/national maps will be important to facilitate real estate and land market activities globally.

- 2. • Indian economyis witnessing a surge in economic development. • Opening of foreign direct investment (FDI) in real estate market has created unprecedented demand for raw land. • Investments in real market are considered to be lucrative in terms of high returns. • Compared to demand for information related to raw land, very little information is available. Emerging Trends in GIS
- 3. • Information requiredby the investors is related to; (i) Ownership status (ii)Availability of transport network e.g. metro or rail/road network etc. (iii)Existing & proposed land uses (iv)Availability of services e.g. water supply, sewerage, drainage etc. (v)Litigations & permissions from local bodies etc.• Above information is maintained by various govt departments but not necessarily in a uniform format. • Such a situation leads to mismatch between information held by two departments. Emerging Trends in GIS
- 4. • GIS hasan important role to play & to act as an interface between various departments which holds crucial information on above mentioned aspects. • These exterior demand on GIS and globalised community will affect &shape the design of future GIS. 1. Firstly, there will be a need for geo referenced base map and cadastre data. 2. Secondly there will be shift in focus from land parcels to buildings/property. 3. Third will be a need for vertical information e.g.- height & underground services. 4. Fourth & most importantly real time updating of Emerging Trends in GIS
- 5. • Then thereare various activities which are intertwined with each other related to complex field of urban development. • Integration of urban development activities with land market world wide, induce the need for regional & national base map network integrated with cadastre information. Emerging Trends in GIS
- 6. Cadastres will movefrom approximate boundary representation towards survey – accurate boundary representations Cadastres will change from purely parcel – based systems towards system of layered property objects. Cadastres will expand from 2D approaches to include 3D and 4D perspectives. Emerging Trends in GIS
- 7. Desperate national and state– based cadastres, indicated red and blue, will become interoperable at regional and global levels. Property interests are now designed around strict bearings around strict bearings and distances or Cartesian coordinates but future cadastres will better model the organic natural environment by enabling fuzzy and dynamic boundary definitions.

- 8. LOCATION Use of satelliteimageries in ROHINI PROJECT of Delhi Development Authority(DDA) was found very useful. This project or sub city for 1 million population spread over 5000 Ha. Of land is located in the North West of Delhi. Existing Base maps were at least 10 years old or in some cases simply not available.
