ASSESSMENT OF SETBACKS FROM THE CENTRE OF THE ROAD TO INFRASTRUCTURAL FACILITIES USING SPATIAL DATA IN WAZIRI IBRAHIM HOUSING ESTATE, DAMATURU TOWN, YOBE STATE, NIGERIA.

Abstract

Spatial Data Infrastructure (SDI) comprises geographic information about the earth’s surface and
its features. This information was in the form of coordinates that describe physical developments
in towns and cities. However, these physical developments were not properly coordinated due to
differences in projection and datum used. Hence, the right of way from the centre of roads to
building lines, power lines and water pipelines was ignored. Scholars and media houses continue
to inform the government and general public on the dangers of ignoring the right of way during
construction as this leads to accidents, uncontrolled fire outbreaks and in some cases demolition
of buildings. This study assesses the setbacks from the centre of the road to the building line, power
line and water pipeline in Waziri Ibrahim Housing Estate in Damaturu Town, Yobe State. Ground
and satellite data for these features were collected and analysed. The results indicated that the
power lines encroached on top of buildings by a distance ranging from 3 to 7m, while the water
pipelines intruded on residential buildings by 2 to 5m which violates the town planning
regulations. Setbacks from the centre of the road to the building lines were reduced from 3 to 7m.
It was recommended that SDI be set up at the state government level so that state ministries of
works, housing; power holding companies and water corporations use spatial data generated by
their respective Surveyors with the same projection and origin. This will contribute to the
realisation of SDG 11 targets 11.1, 11.2 and 11.3. Enhance inclusive and sustainable urbanization
and capacity for participatory, integrated and sustainable human settlement planning and
management in all countries.
