GIS - Geographic Information Systems “a computer system designed to allow users to collect, manage and analyze large volumes of spatially referenced information and associated attribute data”. “a computer based system used to input, store, retrieve, and analyze geographic data sets. The GIS is usually composed of map-like spatial representations called layers which contain information on a number of attributes such as elevation, land ownership and use, crop yield and soil nutrient levels” “A computerized system that provides advanced capabilities for the processing and interpretation of spatial information from the real world” “GIS is a "smart map" tool that allow users to create interactive queries (user created searches), analyze the spatial information, and edit data” INTEGRATION OF SPATIAL DATA & NON SPATIAL DATA

SCOPE OF THE ASSIGNMENT TO ACCOMPLISH Large scale base map covering entire municipal limit. GPS ground control survey for geo-coding & geo- referencing. 1m Contour maps for upland towns and 0.5m contour interval for coastal towns. Above data sets in softcopy format for easy integration with block boundaries, ward boundaries, etc.

Property information captured : plot area, plinth area, SCOPE OF THE ASSIGNMENT …..CONTD…. Updated base maps. Property information captured : plot area, plinth area, property assessment numbers, land use, etc.. Utilities mapped: water supply, under ground drains, street lighting, roads, etc.. Application of GIS software H.R.D. Capacity Enhancement - awareness of GIS by municipal staff

DETAILS OF PROPERTY AND UTILITY MAPPING AND DEVELOPMENT OF GIS DETAILS OF PROPERTY AND UTILITY MAPPING AND DEVELOPMENT OF GIS  The details of properties assessment number (house number wise)  Plot and building boundaries measured.  Building height approximated to the nearest meter with number of floors  Usage of building with trade specification if any  Type of structure The tasks covered

PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. GHMC 4/11/2017  Water Supply details:  Details of intake works including pump station (if any)  Raw water mains  Treatment plant(s)  Built distribution, transmission  Reservoir tanks including balancing tanks and bor In relation to the above material, age and capacity are collected. Information on the distribution system :  The diameter, age, material and condition of pipe  The location of valves and bulk meters  House service connections, public stand posts inter- connections and valves on each line and separately  Transmission mains including pressure mains

PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. Underground Drainage  Trunk sewers, main sewers and sub main sewers  The location of manholes, center to center distance from upstreams manholes and from downstream manholes, house service connections  The diameter, age, material and conditions of pipe Surface Drains  The main town level drains with final disposal points  The intermediately drains and all other drains  Cross section of all drains with clear width and depth (levels)

PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. Street Lighting  Street lighting network system with information about transformers, electric poles, high mast lighting, status of working condition etc. Roads  Road network system with clear hierarchy  Information relating to right of way, carriage way, width of footpath  Information relating to type, condition

PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. Data on property and utilities network: 1. Actual measurement of locations and assets in the field. 2. Abstraction of details from 'as built' drawings. 3. Information from adhoc sources such as field books in local offices and knowledge from long serving employees.

Door numbering system We propose to conduct detailed study on the existing door numbering system in GHMC area provision of door numbers for vacant sites and a new simplified & rationale numbering system will be developed in consultation with GHMC Rust free steel number plates to the buildings with the given specifications of 10’ X 5’ MS pre coated 1mm thickness plate with letters in white and blue background colour. The vacant sites will also be given continuous number.

Existing System of House Numbering The present House Numbering System consists of Ward - Block - House number and the same is being followed since long. The house numbers are not in a continuous series. When a new house comes into existence in between the existing numbers, sub nos. and bye-numbers are given without any order, causing further confusion Entire GHMC will be divided into different blocks. Block boundaries will be drawn in such a way that the boundary is clearly identifiable on ground with reference to land marks. In the new system the entire city will be delineated into Localities and Main roads. The premises are numbered in the Localities and Main Roads separately in a continuous series. 5-digit Locality Code Number is proposed to be given for all the localities, where, first two digits represent Ward Number and the last three digits represent the Locality Number. Similarly all the Main roads are also given unique Code numbers for identification

Delineation of Localities GHMC 4/11/2017 Delineation of Localities Localities are proposed to be delineated in each ward, with the following parameters The locality is viable in terms of area and population and has distinct boundaries. The name of the area is prominent with reference to name of colony, Revenue Village, Post Office, GHMC Council ward etc. The Area is to delineated with reference to ward boundary, Broad Network of roads, Physical Boundaries like Watercourses, Drains, and Railway Lines etc. While delineating the areas smaller localities, colonies, slums that are locally known with reference to prominent locality name are included and comprehensive area is delineated.

APPLICATION DEVELOPMENT Assignment of House Numbers Each premises built-up / open will be assigned with one number. Each Apartment / Commercial Complex will be assigned, with one general number. Each Flat / Shop / Unit will be assigned with by-numbers. Slums which are prone for changes will be assigned two or block wise numbers easy location the houses. Normally the numbering in a locality would start from the corner nearer to the city centre. The street that nearer to the city centre will be numbered as street number 1. Similarly numbering on main roads will be done from one end of the road to the other end and continue the series on the other side till the starting end. A locality may abut main road / roads where there will be separate series of numbers. Detailed locality plans will be prepared for all localities, main roads showing the locality boundaries, streets, lanes, premises with old and new numbers. House / Premises numbers displayed and street boards are fixed.
