Sector overview
The Geographical Information System (GIS) is a framework to collect, store, manage, manipulate, analyse and visualise spatial data. GIS enables to store information in layers and retrieve data to identify unique patterns, solve complex problems, automate processes and build decision support systems. The GIS has the potential to be used in virtually every field. The application of GIS includes urban planning, transportation planning, environmental risk analysis, climate change, flood forecasting and damage estimation, disaster management and mitigation, emergency response, hydro informatics, irrigation water management, reservoir site selection, wetlands mapping, natural resources management, wildlife management, landslide hazard zonation, soil mapping, mineral exploration, modeling renewable energy, agriculture, land information system, public health, waste management, crime analysis and utilities mapping. At NESPAK, the GIS Sector continues to grow exponentially in the engineering and environmental domains.
NESPAK is the pioneer in the GIS Sector in Pakistan and its industry leadership extends over three decades. The Company's vast experience in diverse disciplines has increased its portfolio of GIS projects manifold. So far, more than 60 projects have been undertaken in this sector for local and international clients in addition to providing in-house services for the Company. NESPAK possesses a strong team of GIS experts having excellent technical knowledge and broad experience to ensure successful and timely completion of projects. NESPAK scope of services and experience in the GIS Sector are given below:

As many as 14 projects have been carried out in the utility network sector. NESPAK has recently developed three advanced utility networks projects focused on the Implementation of Web-Based GIS along with Mobile Applications and the Mapping of HT/LT Distribution Networks for IESCO, FESCO, and LESCO. These projects represent some of the most powerful GIS initiatives in the utility sector. A key component is the mobile application designed for the collection of HT/LT and consumer data, including meter and service line information. The heart of the system is an Enterprise GIS application that not only gathers real-time data from the field but also integrates sophisticated algorithms for comprehensive GIS analysis. This includes Load Flow analysis and line loss calculations, which are seamlessly displayed on the web-based application without any human intervention. This system exemplifies the integration of Web GIS, Mobile Applications, and automated data processing to create an efficient and effective solution for managing utility networks.
