Quality Control and GIS Integration in Electricity Meter Installation Audits
This document outlines the processes involved in electricity meter installation quality control (QC) and audits using Geographic Information Systems (GIS). It discusses the compilation of base map information, integration of financial data, and the use of mobile GIS for field data collection. Key components include the use of rugged handheld computers, GPS, and database software for effective data capture and analysis in the field. The report highlights the significance of quality control post-installation and the systematic approach for effective audits linked to municipal systems.

Contents • Base Map Information • Meter and Debtor Information in Financial System • Mobile GIS • Quality Control on Installations • Audit • Delivery • Conclusion
Consumer Meter Audit: Form Design • Data gathered: • Basic Property Information: • position, photo, building information • Electrical Connection Information • position, photo, phase type, meter no, meter reading, meter type, condition, etc
Mobile GIS • Traditional definitions: • Mobile GIS is the expansion of GIS technology from the office into the field. A mobile GIS enables field-based personnel to capture, store, update, manipulate, analyze, and display geographic information; • Mobile GIS is the use of geographic data in the field on mobile devices • Adopted Mobile GIS definition for municipal service delivery • Mobile GIS is the use of geographic data in the field on mobile devices focusing on information gathering • Mobile data capture integrates six essential components: • Rugged handheld computers; • Global Positioning System (GPS); • Camera; • Mapping (GIS)software; • Database software; and • Wireless communications
Mobile GIS Uses • GIS Analysis and Decision Making • Execute GIS analysis while in the field – not really needed except for field data capture monitoring • Mapping • Create, edit and use GIS maps in the field – not cost effective, use aerial photography, etc and only do annotation • Asset Inventory and Maintenance • Create and maintain an inventory of asset location, condition, components and maintenance • Incidents and Inspections • Create a portfolio of evidence with regards to complaints and services rendered, e.g. water leaks, illegal connections, site inspections
