Project Goal

The implementation of the Mobile & Web Application (MoWA), a solution developed on the ArcGIS Enterprise platform for Land Health Assessment (LHA). The initiative aimed to replace manual and siloed workflows with a centralized, location-enabled system to support planning, field data collection, and real-time operational monitoring for TNB. By leveraging ArcGIS field applications and real-time dashboards, TNB successfully bridged the gap between office-based planning and field execution, resulting in improved data integrity and operational transparency.
The paper further outlines the business challenges, solution architecture, implementation methodology, and key outcomes achieved, including increased productivity, reduced operational costs, strengthened data governance, and enhanced decision-making visibility.

Business Problem Solved

Prior to the implementation of the LMU Mobile & Web Application (LMU-MoWA), Land Health Assessment (LHA) activities were largely dependent on manual and fragmented workflows. Task planning and site assignments were managed through spreadsheets, while field data was captured using paper-based forms and subsequently re-entered into digital systems. Field crews operated without access to live, geospatially enabled maps, resulting in several critical challenges:

1) Limited Spatial Data Visibility: Field teams relied on physical plans and static maps, making it difficult to accurately identify land boundaries, encroachments, and site conditions while on-site.

2) Data Latency and Silos: Information recorded on paper checklists often took several days to be digitized into individual Excel files, creating data silos and leading to outdated or inconsistent records. And;

C) Operational Inefficiencies: Route planning and task assignments were performed manually, without spatial optimizat

Technology Implemented

Tenaga Nasional Berhad (TNB) implemented a geocentric enterprise GIS architecture built on three key components of the ESRI ecosystem. This architecture was designed to ensure data integrity, operational efficiency, and enterprise-wide accessibility of spatial information. The three key ESRI ecosystem involved are;

1. ArcGIS Enterprise and Portal for ArcGIS
2. Field Mobility (ArcGIS Field Maps and Survey123)
3. Web Dashboard
