TERMS OF REFERENCE FOR
PREPARATION OF GIS BASEMAP
1. BACKGROUND
1.1 Telangana Government through its Municipal Administration and Urban
Development Department (MAUD), with a view to comprehensively address the
challenges of urban development will implement the Telangana Municipal Development Project (TMDP). The objective is to create economically productive,
efficient and equitable urban centers in the state with increased capacity to reduce
urban poverty. This is to be done by significantly improving the financial viability,
effectiveness, and efficiency of urban services under the control of participating
urban local bodies with a focus on reforms to institutions and practices in addition
to investments in municipal services.
1.2 The Commissioner & Director of Municipal Administration (C&DMA) is
the nodal agency under MA&UD, who will manage the implementation
and monitoring of the project. A Municipal Strengthening Unit (MSU) under CDMA
isheaded by Project Director and supported by Technical Support wing from
DT&CP will oversee the implementation of the project.
1.3 The Project aims at various improvements at three different levels: State, ULB,
and Subprojects. The Project focuses more on improvements at lower
levels. Reforms and Capacity Building at ULBs require Technical Assistance and Local Policy Actions, whose design and implementation need sustained support.
Financing of urban investments would not only alleviate urban service
deficiencies but also provide an incentive and concrete platform for local Capacity
Building, with detailed monitoring and support.
1.4 Water supply and Sanitation provisions are the most conspicuous
of municipal activities. However, lack of planned capital investment and
inadequate operation and maintenance, combined with a growing
population demanding higher service levels has reduced the effectiveness of
water supply and sanitation services in many municipalities.
GIS Basemap preparation for 22 ULB’s P a g e | 4
1.5 The project has four major components, namely, i) State Level Policy and
Institutional Development Support, ii) Municipal Capacity Enhancement, i i) Urban Infrastructure Investment and iv) Project Management Technical Assistance.
1.6 In Telangana state, the municipalities are governed by the Municipalities Act
of 1965. The corporations are governed by theHyderabad Municipal
Corporation Act of 1955. Inadequate Water Supply, Sanitation and wastewater
Management has been an essential issue in many urban local bodies.
In order to address this, fund in the form of Loan is received from the World Bank
for Municipal Development Project.
1.7 The Project development objectives of MDP are to help improve high-priority
urban services in selected cities of Telangana,and build the capacity of Urban Local Bodies to develop and manage urban services. The
Project will support improvements in the Financial, Technical, and
ManagementCapacities of all the ULBs of Telangana, in addition to infrastructure
financing.
1.8 These are required to ensure the effectiveness of urban planning in thecontext
of current and future economic expansion in the State. The conventional
procedure of preparing statutory urban development plans is seen to be devoid of
effective participation, unconcerned about financing implications and time
consuming. A concurrent but separate study seeks to establish the reformed
legislation, simplified land use planning procedure and lay down guidelines for
town planners of ULBs in preparing the city plans.
1.9 For efficient, economical and meaningful municipal administration, including
the tax administration, a comprehensive and integrated data set through GIS
application has become essential. To achieve the goal of electronic governance
for all the services of the ULBs, large scale and detailed GIS base maps are required. TMDP intends to appoint a Consultancy firm / Agency to carry out
thework of preparation of GIS base maps for 18 ULBs using Geographic
Information Systems (GIS) platform.

Simultaneously with Task-1,the Consultant shall collect maps and secondary data from various authorities. A set of such maps that will form a part of the spatial
database is illustrated below:
(a) Master Plan / General Town Planning Schemes showing proposed land use
zoning, transport network and sites designated for various public purposes.
(b) Maps showing administrative boundaries of ULB jurisdiction, administrative
and electoral wards, area/ block units used by census. (c) Base Map/ Revenue Maps showing Cadastral Boundaries.
(d) Maps/ Engineering drawings of utilities like water supply, sewerage, storm,
water drainage, solid waste disposal, roads and street lights along with the
data available with ULB/ any other concerned Department.
(e) Data regarding services like Fire Protection, Cremation and Burial Grounds,
Slaughter Houses, Cattle Ponds, Parks, Gardens and Swimming Pools etc.
GIS Basemap preparation for 22 ULB’s P a g e | 19
In case such data is missing, this will form a part of the field survey/
verification. (f) Locationof State and Central Government offices,railways and highways, all
roads along with centerlines, post and telegraph offices, police stations,
primary & high schools, colleges, universities, primary health centers,
hospitals, banks, theatres etc. also need to be located on the maps through
field verification.
(g) Existing land use categories like residential including slums, industrial,
commercial and healthcare, educational, sports and recreation facilities.
(h) Property boundaries along with slum boundaries (Notified and Non- Notified).
In case such data is missing, this will form a part of the field survey/
verification.
(i) All features should be collected along with the necessary attributes that will be later used for annotation.
(j) Preparation of survey proforma for each of the layers to be generated.
TASK 8: INCORPORATION OF CADASTRAL INFORMATION
After collection of map mentioned in Task No.7, all maps have to be scanned as
raster images and the vectorisation of scanned raster images shall be done with
label symbology and annotation with unique Ids. Digitized map shall be geo-
referenced with satellite image using sufficient numbers of GCPs before
incorporating the cadastral and utility information.
Overlay of Cadastral Maps on High-Resolution Satellite Image (HRSI):
The vectorized cadastral maps are overlaid on high-resolution satellite images to
find out the changes in parcel quantity and quality in terms of size and shape. The
analog cadastral maps are vectorized and village-level digital cadastral maps are prepared.
For each village it is suggested to have 15 to 20 GCPs are collected with
reference to HRSI. The GCP numbers and their distribution play a major role in
overlaying the cadastral maps on HRSI with good accuracy.
GIS Basemap preparation for 22 ULB’s P a g e | 20
For transferring the cadastral map to the HRSI image, the mathematical model
used is the affine transformation model is suggestive. The model is to be validated in terms of residual error at each GCP location and root mean square value of the
model. In general, the threshold for RMS value and residual error is sub-pixel
respectively.
Based on the validated model, the village cadastral maps are to be geo-referenced
and new outputs are to be generated.
The individual geo-referenced vectors are overlaid on HRSI. The primary network of each village map, i.e., road network, drainage network, water-bodies and abadi
area is verified across the village. Well-defined field boundaries are also validated.
Using a similar process, all villages in a tehsil/taluk are geo-referenced and
validated.
All the village maps are overlaid on the satellite data and validated for under-lap
and over-lap across the villages as per the acceptable threshold of the ULB. Based on the thresholds, appropriate corrections are carried out.
After due corrections, a single mosaic of all the village parcels of the ULB is to be
generated and super imposed on to the Basemap.
TASK 9: FIELD VERIFICATION SURVEY The Consultants / agencies have to carry out the field surveys to verify the proof/ check plots of maps marked for incomplete features with reference to the ground, collect the information on features, especially man-made ones, available on satellite images, collection of names for important land marks, roads/ streets/ lanes/ by-lanes, areas, etc. or any other feature not captured in the HRSI. Check the accuracy of some points on the ground randomly to meet the accuracy standards. The surveyors for field verification shall go round, street by street, to verify the features that are marked on proof plots.
TASK 10: DRAFT BASE MAP
The Draft Base Map along with a reporton various gaps identified shall be consolidatedand prepared. The draft map should be made available in soft copy
(formats to be finalized during workshop. Preference would be for a platform/
