2. 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

33. 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.

34. 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

35. 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.

36. 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.
