Challenge
Redland City Council identified a backlog of more than 100 spatial asset records that had not undergone formal quality assurance or peer review over multiple financial years. This created uncertainty around the accuracy, consistency, and completeness of GIS data used for asset management and financial valuation. The data originated from various sources, including developer-submitted ADAC XML files, DWG drawings, and PDFs, increasing the risk of inconsistencies. Council required a reliable process to validate asset attributes, ensure alignment with financial systems, and confirm that all spatial records accurately reflected “as constructed” conditions to support operational and reporting requirements.
Solution
GIS People undertook a structured quality assurance process to validate spatial asset data against surveyed “as constructed” drawings. Using Esri software, each dataset was reviewed to ensure alignment with financial records and correct asset classification. The process included verifying key attributes such as material, dimensions, levels, valuation factors, and unique identifiers. Data supplied in ADAC XML format was cross-checked with supporting DWG and PDF documentation where required. Comprehensive QA reports were produced for each job, detailing findings and corrections. This approach ensured consistency across multiple asset classes, including roads, stormwater, sewer and water infrastructure.
Outcomes
- Improved confidence in spatial asset data accuracy and alignment with financial valuation systems.
- Established consistent QA process across multiple infrastructure asset classes.
- Delivered detailed reports supporting transparency and informed decision-making.
