GEOSPATIAL MAPPING OF BURIED SERVICES: WATER DISTRIBUTION SYSTEM OF EDO STATE POLYTECHNIC, USEN AS CASE STUDY

Abstract

Geospatial mapping is a spatial visualization method that enables the creation of customized maps
to address specific requirements. Its primary aim is to show items with geographic coordinates in a
geographical framework, providing a representation of the physical world on a map. Various
approaches, solutions, and Geographic Information Systems (GIS) software can be employed to
analyze existing geospatial data and geographical and terrestrial databases. Potable water supply is
fundamental for food production, and therefore human existence. Lack or shortage of fresh water
can impact negatively on the ecosystem and predispose human and animals to dangers such as
water-borne diseases and even death. Water distribution systems are key to the provision of potable
water to the public. The location records of these facilities assist in their maintenance, protection
and provision of steady supply of potable water. The map and location coordinates in Nigeria
Transverse Mercator (NTM) of the water distribution network of Edo State Polytechnic, Usen is in
figure and table respectively. Edo State Polytechnic water distribution network has a total length of
4,008.607m as shown in figure 5, and coordinates for its various pipes shown in table 2.
