Regional Information System
|
A computer based Regional Information System is developed
and maintained by the MMRDA. Basic data on population, employment,
industries and other sectors are regularly collected and
processed. The information system facilitates the planning,
development and co-ordination functions of the MMRDA. Training
programmes for the staff of the MMRDA and local authorities
in MMR on use of computer systems and softwares are periodically
conducted.
A Geographic Information System (GIS), which integrates
the maps and attribute data in digital form, is extensively
used for organising various databases. The software used
is: PC ARC/INFO with NETWORK and PC TIN modules together
with ARCVIEW.
The following spatial and non-spatial data are
stored under the GIS at 1:250,000 scale:
-
SOI topo-sheets:
Soil type, Soil texture, Slope, Physiography and Flooding
hazard zones;
-
Derived information
from SOI topo-sheets:
Coastal proximity and Altitude;
-
Satellite imageries:
Land-use; and
-
Other information: Industrial area
distribution, Environmental data on air pollution pertaining
to SO2, SPM and NOX levels.
The
following spatial and non-spatial data are stored under
the GIS at 1:50,000 scale:
-
Census sections in Greater Mumbai
and Village boundaries from the village maps at
different scales obtained from the
office of the Land Records
-
The non-spatial data from
census and other sources for the years 1971, 1981,
and 1991 corresponding to the above
spatial
data.
The spatial database is being updated by procuring IRS-IC
satellite imageries at 1:50,000 scale LISS-III and
1:12,500 scale PAN geo-coded products. Various demonstrative
studies
like Development Plan Monitoring, water supply network
analysis and air pollution monitoring have been undertaken.
A few
collaborative projects have been carried out with
the Space Applications Centre, Ahmedabad and the National
Remote Sensing Agency, Hyderabad to demonstrate the application
of GIS in
urban planning and management.The following publications
give an overview of the applications of GIS made
