2GIS - 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

Capacity Enhancement - awareness of GIS bymunicipal staff
12FEATURES CAPTURED IN BASE MAP Road network of all types of roads with associateddetails. Rivers and drainage systems including all waterbodies. Railways with associated details. All built up structures such as human settlements, industries, educational, recreational, religious etc. Utility services such as water supply, seweragesystem, power distribution etc.

22DETAILS OF PROPERTY AND UTILITY MAPPING AND DEVELOPMENT OF GISDETAILS 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 structureThe tasks covered
23PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. GHMC4/11/2017 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 borIn 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
24PROPERTY 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 pipeSurface 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)
25PROPERTY 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
26PROPERTY AND UTILITY MAPPING & DEVELOPEMNT OF GIS ………contd…….. Data on property and utilities network:Actual measurement of locations and assets in the field.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.

33Door numbering systemWe 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 GHMCRust 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.
34Existing System of House Numbering The present House Numbering System consists of Ward - Block - Housenumber and the same is being followed since long.The house numbers are not in a continuous series. When a new house comesinto existence in between the existing numbers, sub nos. and bye-numbersare given without any order, causing further confusionEntire GHMC will be divided into different blocks. Block boundaries will bedrawn in such a way that the boundary is clearly identifiable on ground withreference to land marks.In the new system the entire city will be delineated into Localities and Mainroads. The premises are numbered in the Localities and Main Roadsseparately 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 digitsrepresent the Locality Number. Similarly all the Main roads are also givenunique Code numbers for identification
35Delineation of Localities GHMC4/11/2017Delineation of LocalitiesLocalities are proposed to be delineated in each ward, with the following parametersThe 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.
36APPLICATION DEVELOPMENT Assignment of House NumbersEach premises built-up / open will be assigned with one number.Each Apartment / Commercial Complex will be assigned, with one generalnumber.Each Flat / Shop / Unit will be assigned with by-numbers.Slums which are prone for changes will be assigned two or block wisenumbers easy location the houses.Normally the numbering in a locality would start from the corner nearer tothe 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 tothe 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 ofnumbers.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.
