Street Addressing System and House Numbering System of Ward 4 Dhulikhel Municipality

House numbering is a system of providing a unique number to each building in a street or area,

intending to make it easier to locate. The house number is often part of a postal address and

describes the number of a building (residential or not). Street Numbering was first introduced

across Europe in the 18th century, to facilitate administrative tasks and the provision of services

such as the post.

Street and house addressing provides a logical and easily understandable system to identify

geographical locations using a system of maps and signs conveying numbers or names of streets

and houses or buildings. The designation of the house address is defined concerning its access

street. This operation of house addressing also serves to improve urban and municipal

management. Street addressing provides an opportunity to create a map of the city used by

different units of the municipality, collecting significant information about the city and its dwellers

and setting up a database on the built environment. Information gathered is associated with an

address making it easily locatable. The database which takes the form of GIS is the major creation

of street addressing initiatives, particularly in Nepal with rapidly growing urban areas.

Recently, TDF has received financial support from the European Union (EU) under the Thematic

Programme: Civil Society Organization and Local Authorities (Contract: CSO-LA/2018/402-797)

for the implementation of ‘Municipal Finance and Capacity Building (MFCB) Programme’ to

strengthen local authorities and the TDF to foster local economic development and climateresilient

investment through blended financing. Under the institutional development component

of the MFCB Programme, TDF intends to hire a consultancy for designing and implementing a

GIS-based house numbering system and street addressing system along with a manual for

implementation of the system in Dhulikhel Municipality.

The major datasets used for the research are existing geometric shapefile of building footprints

and road networks which are collected and compiled from the Municipal Transport Master Plan

(MTMP) of corresponding local authorities. The spatial reference of the data sources used in this

research was based on World Geodetic System WGS 1984 (WGS84). The municipal and ward

boundary were obtained from Survey Department under the Government of Nepal (DoS, 2020).

The new buildings constructed after the preparation of MTMP were digitized from Google Earth.

Google Earth is a popular virtual globe software with open access and a user-friendly interface

that provides realistic and engaging images of the Earth's surface.

Methods

Road Network Datasets

The Road network is one of the essential components for the generation of metric house numbers. The municipal road networks are categorized as per their functional hierarchy as National
Highway (NH), Feeder Roads (FR), District Roads (DRCN), and Urban roads of various subcategories
such as Class A, Class B, Class C, and Class D (DoR, 2013) as shown in Table (1). The
right-of-way (ROW) of each road category as per respective guidelines are as below.

Each building unit is connected to at least one street, followed by the measurement of the distance

of the street segment to the building units. So, the road should have a unique ID, road name, class,

code, RoW, width, and surface status. The full code of road comprises the information of province,

district, municipality, road category, and several road segments as below in Table (2) and provides

base data for house numbering.

The orientation of the road is also an important factor in the measurement of distance. Generally,

road alignments are directed from east to west or north to south. The road is directed from west to

east or eastward, the initial west point of the road is considered the start point of the road. Whereas

the road is directed from south to north or northward, the initial south point of the road is

considered as the start point of the road. The rule is not applicable in all situations such as a dead-end

road directed from east to westward or a branch road starting from the main road.
