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.


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.


2. OBJECTIVE OF THE STUDY 1. 2. 2.2 Project development objectives are:

The objective of the assignment is to Prepare GIS Base Maps for Urban

LocalBodies (ULB) in Telangana state using Geospatial technologies to assist

theULBs in strategic planning and resource utilization, management function andplanning & management of day to day operations. The area of the ULB

toprepare Base Map includes the area up to the present administrative boundary

asindicated in Annexure-I

2.2 The project’s specific development objectives are to:

(a) Improve urban governance and finance through the implementation of an

agreed reform agenda at State and Local levels. (b) Enhance the capacity of State, Local, and Community groups to manage

urban affairs through a demand driven capacity enhancement program; and

(c) Support the rehabilitation and creation of sustainable urban services with

economic and social benefits at community and city-wide levels.

3. BRIEF DESCRIPTION OF TASK 3.1 Telangana Municipal Development Project (TMDP) intends to appoint Consultancy

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.


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/

software independent geo-database file). Hard copy maps in duplicate at 1:1000 in

A3 size, 1:5000 in A1 size&1:10000 in A0 size to be submitted.


TASK11: QUALITY CHECK ON DATA SUBMISSION, DATA SECURITY GUIDELINES & DATA VERIFICATION
