Remote Sensing & GIS

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.

A number of processes are involved in effectively

managing waste for a municipality.

These include monitoring, collection, transport,

processing, recycling and disposal.

MSW

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

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.

Types of bins

Types of Vehicles

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.

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

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.

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 .

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 Persons/sq.kmSource-Dr.K.Rasppan, Professor – CIT, Coimbatore

Based on population of each ward and the waste generation of each ward using this per capita waste generation map were prepared. Per capita solid waste generation is denotes (Total weight of solid waste generated per day) Per (Population served) Source-Dr.K.Rasppan, Professor – CIT, Coimbatore

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)

Disadvantages

Expensive software Impossible without minimal training Time consuming Process

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.
