GIS plays vital role in decision making process Location convenience is very important in the service
sector. Time, cost of transport, convenient place, service
provided by consumers, suitability of sites etc. are crucial factors in service sector.
Suitability analysis used to give best sites for new ATM sites
Margao is commercial capital of Goa. Density of existing ATM centers and new sites for
proposing ATM mapped.
To assess the density of ATM centers in Margao city
To give site suitability for new ATM center with the help of GIS
Data based on primary and secondary form
Primary data collected from GPS points of all ATM centers, customer details, card holders of each banks
Secondary data based on satellite images, Toposheet, research articles and magazines etc
GPS data points imported to GIS software
Sample survey methods for each banks using questioner format. Questions such as Number of customer
Number of Account Holder
Number of Account Holder with ATM
Approximately percentage of Card holders of that area
Vector operations are as follows used in this work
Georeferenceand Digitizing ward boundry
Import all GPS data
Mosaic and Georeference

Clip image with village boundery
Digitization of Road and Settlement
Digitization of land use
and land cover
Prepare Land use and land

Prepare Exisiting ATM centers map
Final map of ATM, Roads, Settlement
and Land use and Cover

Introduction to Margao
Commercial Capital of goa
Covering nearly 24 sq.km area
More service sector
Nearness to tourist places, better transport and communication facilities creates scope for banking activities
Nearly 25-30 banks having 52 ATM centers
Market area having more density of ATM centers
Difficult to get customer data from banks
Very few works done in India
2011 census data not yet published thus used 2001 census data for demographic factors
Each banks have different policies to construct the New ATM
Density of each ATM points calculate
Kernel density estimation used
calculates the density of features in a neighborhood around those features.
To estimate density categories given such as Very High Density High Density Medium Density Low Density Very Low Density
Distance from first class to second class is nearly 300-400Mt
Market area and KTC area shows highest density and power house , Dowerlim, Fatorda shows the lowest density

Site suitability analysis used to give new sites for the ATM centers
For site suitability following methods are used Multiple ring buffer Reclassification Slope Distance Density
Weighted overlay Conditional operators using CON Optimal site selection from settlement and road buffer
The purpose of reclassification is to create new raster layer by changing the attributes value of the cell of the input layer.
This usually takes one of the following forms that used either logical or arithmetic operators
Ascending the values to classes or range of old value with the purpose of reducing the number of the classes in the original input layer or to group value into categories in a new classification.
Weighted Overlay is a technique for applying a common measurement scale of values to diverse and dissimilar inputs to create an integrated analysis.
Geographic problems often require the analysis of many different factors.
For instance, choosing the site for a new housing development means assessing such things as land cost, proximity to existing services, slope, and flood frequency.
Within a single raster layer, you must usually prioritize values.
For example, a value of 1 represents slopes of 0 to 5 degrees, a value of 2 represents slopes of 5 to 10 degrees, and a value of 3 represents slopes of 10 to 15 degrees.
If slope is a criteria in finding a new site, for example, and your evaluation scale is from 1 to 9 by 1, you might give a scale value of 9 to the input value of 1 (the most suitable areas with least steep slopes), a scale value of 6 to the input value of 2 (the second most suitable slopes), and a scale value of 3 to the input value of 3 (the least suitable, steepest slopes).
If it was decided that slopes greater than 15 degrees would not be considered, all input values greater than 3 would be assigned a scale value of restricted to exclude them.
Site selection based on following criteria Influence of Land use and Land cover such as Barren
land, Settlement, Open Land etc
Distance from the Road ( 30-50 Mt)
Density pattern of existing ATM
Settlement
Number of bank customer and Number of card holders
Buffering from settlement and intersecting Road
With the help of site suitability analysis we can give best suitable sites for recreational sites
SBI, HDFC, ICICI, kotak mahindra, union bank having highest number of ATM
BOI having more customer nearly 20000-30000 in Fatorda, Aquem area but no ATM centers
BOM and IDBI banks also having low frequency of ATM
Doverlim and Power House ,ravanpond, Pajifond area having very low frequency of ATM centers though this area having highest population
Location convenience is an important factor when customers select a financial institution.
Doverlim, PowerHouse, Sonsodo, Gogol, Fatordaarea have potential for constructing the new sites for the ATM centers
BOI, BOM, IDBI banks have great potential to settled the New ATM centers in Gogol, Fatorda, Powerhouse and Dowerlim area because of highest number of customer and population
