Geographic Information System (GIS) is used to input, store, retrieve, manipulate, analyze and output geographically referenced data. In order to support decision making for planning and management of land use, natural resources, environment, transportation, urban facilities, and other administrative records.The Role of GIS is very large as many aspects of its planning and operations are highly dependent on spatial data & also provides a digital data bank for future monitoring program of the site…….etc

4. GIS
 Geographic Information System (GIS) is used to input, store,
retrieve, manipulate, analyze and output geographically
referenced data.
 In order to support decision making for planning and
management of land use, natural resources, environment,
transportation, urban facilities, and other administrative
records.

5.  A number of processes are involved in effectively
managing waste for a municipality.
 These include monitoring, collection, transport,
processing, recycling and disposal.

6.  Site Analysis (Synoptic Views)
 Route optimization
 Multispectral Capability
 Fuel Consumption
 The Role of GIS is very large as many aspects of its
planning and operations are highly dependent on
spatial data & also provides a digital data bank for
future monitoring program of the site…….etc
MSW Practice

7. Transportation Model
 Based on population density, width of roads, availability of space and
minimum travel distance from a house, three types of bins viz.
 Type-A (7.0 m3), type-B (0.75 m3), type-C (0.5 m3) have been
proposed to be placed in different parts of the city.
• Collection of solid waste is carried out by using suitable vehicles. The
type of vehicle to be used depends on the type of collection bin and
width of road.
• All of the mechanized vehicles are chosen to reduce the pick-up time
of bins at different locations and thus to reduce the number of vehicle
requirements.

8. Types of bins

9. Types of Vehicles

10.  Vehicle Type-A: It is a skipper type of vehicle having a
length of 4.5 m. It lifts only A-type bins and travels only on
the major roads. It can carry only one bin at a time.
 Vehicle Type-B: It is a lifter type of vehicle with a
frontloading mechanism and lifts B-type bins and travels
both on major and minor roads.
 Vehicle Type-C: It is an auto-rickshaw type of vehicle and is
used for the collection of waste from the congested areas.
It can collect wastes from C-type bins and unload it into
the nearest A-type bin.

11.  GIS provides an effective means for import, management
and analysis of spatial based data.
 Dedicated to the reallocation of waste collection bins,
making use of the GIS spatial analysis functions.
 Finally, performs the optimization of routing for minimum
time, distance, fuel consumption and gas emissions with
the use of ArcGIS Network Analyst GIS

12. Spatial Analysis
 Location of dumping site to suitable site for the
disposal of urban solid waste generated areas using GIS
techniques.
 The principal sub criteria that used for spatial analysis
are lithology, geomorphology, slope, drainage,
population, distance from major roads, distance from
major streams and distance from drainage.

18. Case Study - Coimbatore
 LATITUDE - 11°N
 LONGITUDE - 76°E
 411.2 meters above SL.
 Area - 257km²
 100 wards
 Population - 2,151,466 - (2011 census)
 ANNUAL AVG. SOLAR RADIATION - 4.98 kWh/m²/day

19. Coimbatore City
Zonal Ward map
Consists 4 Zones and each zones contains 18 wards, Each zone is
headed by an assist. commissioner who is delegated with adequate
powers to discharge his functions effectively .

20. The Arc view calculator was used to obtain the P.D value. It denotes that No of persons
Per Area of ward. More than 50% of the wards are identified with density b/w 9934 to
28727 persons per sq.km. These are the potential wards for development and high
growth rate is attributed to these wards About 20 wards densities ranging up to 9933

22. Advantages
 In-depth analysis shown on a single page –no written
explanation needed.
 Audience needs no special knowledge or training to
understand maps.
 Works perfectly with simple graphs and charts to present
study results or any data to decision makers (legislators,
community partners, administration)

23. Disadvantages
 Expensive software
 Impossible without minimal training
 Time consuming Process

24.  Remote sensing and GIS makes easier to get valuable
information about the study area.
 GIS enables us to integrate different layers and to manage
large database.
 It gives more accurate results when compared to conventional
methods.
 Hence GIS is proved to be a powerful tool in managing spatial
and non spatial databases in suitability evaluation.
