The document describes using GIS techniques to enhance property tax collection in Shakarpur, East Delhi. It involves validating property data from the Delhi Spatial Data Infrastructure (DSSDI) project with records from the East Delhi Municipal Corporation (EDMC) to identify tax defaulters. The first phase involves cross-checking DSSDI spatial data on buildings and units with EDMC's tax ledger to find missing or incorrect records. The second phase entails field surveys to update property information. Analyzing the validated data identifies buildings in the DSSDI but not the ledger, and vice versa, as well as matches, helping EDMC collect taxes from defaulters more efficiently.

tax defaulter

3. Lets just know about TAX ?

4. TAX
Tax is a financial charge or other levy imposed upon a legal entity by a state or the
functional equivalent of a state to fund various public expenditures.
TYPES OF TAXES
 Taxes on income
 Taxes on goods &services
 Taxes on property
PURPOSE OF TAX
 To raise revenue to fund government.
 It include in the expenditure on economic infracturse road, public transportation,
sanitation legal system etc.

5. MUNICIPAL CORPORATION OF DELHI
 The Municipal Corporation of Delhi (MCD) is an autonomous body that governs 8 of the
11 districts of Delhi, India.
 It is one of three municipal corporations in the Capital, the others being New Delhi
Municipal Council, and Delhi Cantonment Board.
 The MCD is among the largest municipal bodies in the world providing civic services to
more than estimated population of 11 million citizens in the capital city.

6. ZONES OF MCD
 Mainly MCD is divided in three zones namely North, South and East.

7. EAST DELHI MUNCIPAL CORPORATION
 The total number of wards under EDMC are 64

8. TAX COLLECTION

9. PROBLEM FACED BY MCD IN TAX
COLLECTION
Major Issues Faced by MCD
• Large number of properties were
unassessed and not brought under tax
net
Unassessed Properties
• Records are tampered
Tampered Records
• Improper assessment of property tax by
officials which was causing huge revenue
loss
Incorrect Assessment
• Low rate of filing the property tax returns,
Negligible penalty for not filing the returnNegligible Penalty of
Defaulters

10.  Reason
Lack of complete and
apposite database.
Lack spatial information of
properties.
Lack of exclusivity in
available dataset.
 Solution
Spatial Database
Individuality of each property
Address of the Properties
Other attributes such as usage,
No.of floors

11. Geospatial Delhi Limited is a Government of NCT of Delhi Company

 Geographical Information collected from the Field survey of the properties as
well as the 3D spatial informations inherited from the DSSDI project is made
available to the MCD through the Delhi Geo-Portal.
 DSSDI- Delhi State Spatial Data Infrastructure, is a project initiated by Survey
Of India(SOI) as a 3D GIS solution including generation of a large-scale base
map to cover the state of NCT of Delhi( 1500 sq. kms)
 Joint Validation of the DSSDI data and the MCD ledger is made to get the
required accurate information of the properties and the information of the
tax paid history thereof.

 Structure Type
 Use Factor
 Occupancy Factor
 Age Factor etc

19. MANAGEMENT INFORMATION SYSTEM AND
GEOINFORMATION SYSTEM
• An Integrated approach to both GIS and MIS is being used here.
• Using MIS, we collect the personal information that is required for
finding out the defaulters, while using GIS we have the geological
details such as location, area coverage, etc.

20. SCOPE OF THE PROPOSED WORK
 Scope of work involves joint validation of the DSSDI data with EDMC ledger data
to find defaulters (listing of properties not covered in taxation) and
subsequently to generate Unique Property ID on all property parcels of Delhi.

21. STUDY AREA
• ENHANCEMENT OF PROPERTY TAX IN SHAKARPUR AREA

22. DATA SOURCE
 SATELLITE IMAGE :WorldView-2 satellite sensor, launched October 8, 2009, provides
0.46m Panchromatic (B&W) mono and stereo satellite image data.
 MCD DATA : MCD(Municipal corporation of Delhi)provide excel data. In the excel data
they give the entire information of the Shakarpur area with one by one building
information like (occupant name, building id ,DSSDI ,floor num etc)
 SOFTWARE INFORMATION: arcGIS 10.2.2 is used for analyzing the satellite image and
MCD excel data

23. METHODOLOGY AND WORKFLOW

29. GEOCODING
 Geocoding is the process of transforming a description of a location—such as a pair of coordinates,
an address, or a name of a place—to a location on the earth's surface.
 The types of locations that you can search for, include points of interest or names from a gazetteer,
like mountains, bridges, and stores; coordinates based on latitude and longitude or other reference
system
 Geocoding is the process which is used for cross checking building DSSDI id for QC.
 It is one of the best process for generating point and give accurate result.

34.  the Geocode tool where the process of assigning location to address to that they can be placed as
points on a map, similar to putting pins on a paper map, and analysed with other spatial data.
 Through this we can know through the score if 100% given that means the points match’s & if 0%
which means some kind of error has done.
 By doing this we get to know who paid & not paid tax.
 After spatial joining and sorting of data, analysis is done on each and every individual
record to identify the following points and final spatial map with list of the individuals
are generated.
Building information available in EDMC Ledger but not in DSSDI data
Building information available in DSSDI data but not in EDMC Ledger
Building information matching with the EDMC Ledger and DSSDI
The results of the pilot work for Shakarpur are depicted in the following maps

35. FINAL OUTPUT

36. PHASE II:Ground Validation/Field Survey
 A full pledged ground validation of property data (door to door) will be
carried out to obtain property information on Single-family dwellings, multi-
tenant dwellings, and commercial entities apartment complex/business complex
inventories.

37. Tranning for field survey Collect build data and
instrument for field survey
Identify Ward and area
Updation information
of building or give mcd
notice
Then match building,
floor& house no
identify owner

38. Analysis & Results
 The Methodology shows that the features created during joint validation are valid to participate in
the analysis along with existing database.
 A new file is created to enhance the inputs from property data of GSDL (DSSDI Buildings and
Building units) EDMC Ledger and online taxpayers.
 This database population involves two stages.
Firstly, the fields in the geo-database (BUILD_ID, D.H.S No., OCCUPANT, Locality,
etc.) are populated.
Secondly, the fields of the external database (External Database entry) are filled with
respective attribute data. For that spatial joining functions are used to correlate ledger
data with property data of GSDL (DSSDI Buildings and Building units)

39. CONCLUSION
• DSSDI project was an outcome of a pilot project , of GNTCD Government of NCT of Delhi
Company, on GIS in shakarpur area, Delhi.
• The project has proven to be of immense usefulness, especially the GIS databases, for various
applications for Government of Delhi.
• It has enabled change detection on real time as occurring on the ground. DSSDI project help MCD
to accruing full information of an area and provide information to MCD about the tax payers and
defaulters .
• These information is used for field survey and provide notice to the defaulters.
• By the identifying and matching of information of the MCD data and GSDL data mcd can get
accurate information of tax payers and defaulters .
• Through these information MCD can take strict information on defaulters.
