BMTC GPS/GIS GIS applications for route
planning and vehicle tracking have been implemented in the West. Such an
application for the tracking of private buses operating under the BMTC is being
proposed. The use of Global Positioning System to monitor the location of the
buses and generate appropriate bills based on distance traveled is on the anvil.
The pilot project is to track 200 buses, which will then be expanded to 2000
buses. Provision for interfacing the data with the GIS of Bangalore City, being
developed by ISRO, is also being planned.
BWSSB GIS BWSSB has
planned to develop a GIS to map and monitor the water supply and sewage systems
in the Bangalore region, day to day maintenance of the system will be enhanced
by developing a complete database on the technical components of the network.
The system would also help to plan extensions to the network. A French
consulting firm is developing the system.
Sathyanagar Layout GIS
Sathyanagar Layout near Banaswadi Main Road, Bangalore was selected by the
Centre for Environment Education (CEE, South), Bangalore for carrying out
improvements to the environment. In a related project, a Comprehensive
Development Plan (CDP) of the area was to be prepared.
For carrying out
the activities, physical plan (base plan) of the layout and socio economic
information about the residents of the layout was necessary. Instead of
following the traditional method of preparing physical plan (carry out a
physical survey and draw it on a hard copy), a computerised GIS was developed.
The advantages of such a GIS would lead to easy retrieval & modification of
data and preparation of outputs. Other advantages of GIS software like spatial
analysis (buffering, overlay, queries, etc.) and non-spatial analysis (basic
statistics like standard deviation, mean, sum, etc.) can be availed. Preparation
of thematic maps that would aid in identifying problems & communicating with
the stakeholders is facilitated.
A GIS system for the Sathyanagar Layout
using the desktop mapping GIS software Maplnfo 4.0 was implemented by TIDE for
CEE. The GIS of the Sathyanagar contains both physical & socio-economic data
that can further be used by CEE for preparation of CDP. Base map at 1:500 scale
contains building data and shows the footprints of the building. Location of
physical infrastructure such as roads, taps, streetlights, garbage bins are
given on the map. Also included in the database are photographs of the lay out
taken at some locations. Contours are also mapped.
The individual houses
were mapped and the socio-economic-physical survey was linked to the map data,
so that spatial analysis could be carried out to give an understanding of any
spatial patterns.
Plane-table survey was carried out to prepare maps at
1:500 scale. All the aboveground features as mentioned below were surveyed &
mapped.
Entities surveyed and mapped:
- Footprint of houses and other buildings
- Roads inside the layout
- Above ground services like drains, etc.
- Other entities like trees, water taps, hand pump, stone slabs, etc.
- Outline of the lake
- Spot height at 5.0m interval
- Immediate surroundings
- Socio-economic mapping was done to obtain the following details at household
level.
- Number of dwellers
- Age-wise population data
- Occupation
- Physical condition of buildings
- Income
- Literacy
- Use of existing spaces, etc.
The GIS is being extensively used
by CEE for its activities in the layout. CEE is presently using the system to
plan a drainage system for the area.
Malleswaram GIS The
Geographical Information System created for Malleswaram ward contains both map
and attribute data of all the parcels that come under Malleswaram, Ward-7
of Bangalore City. It contains map and attribute data of roads, features on
the roads, landmarks, and other services. These data were computerised using one
of the standard GIS software, MapInfo so that the final product is in a form
useful for solid waste management, planning and monitoring. The files were
converted into Arcview format so that the information can be viewed by means of
freeware available for viewing, such as Arcviewl.0 and Arc Explorer. This
project was carried out in co-ordination with Mythri Sarva Seva Samithi and
Bangalore City Corporation (BCC). This data is also available with Centre for
Science and Technology, Malleswaram, and Swabhimana, Malleswaram. (For more
details refer to GIS@development March-April, 1998 issue.) It is hoped that
these efforts would act as forerunners for such similar efforts throughout
India.
