An evaluation framework for comparing geocoding systems.

Area of Science:

• Geospatial Health Informatics
• Health Services Research
• Geographic Information Systems (GIS)

Background:

• Geocoding is crucial for spatial health studies, impacting data quality for agencies and consumers.
• Evolving geocoding systems necessitate robust evaluation criteria for organizational decision-making.
• Existing criteria often lack a holistic view of geocoding systems within large organizations.

Purpose of the Study:

• To develop and test an evaluation framework for large organizations selecting geocoding systems.
• To provide criteria for assessing geocoding systems based on operational needs and organizational context.
• To support informed decisions regarding building, buying, or maintaining geocoding platforms.

Main Methods:

• A geocoding platform evaluation framework was developed by reviewing geocoding accuracy literature.
• The framework extends standard geocoding metrics to address the specific needs of large health organizations.
• A case study evaluated five geocoding platforms in the Australian market.

Main Results:

• The evaluation framework successfully differentiated geocoding systems based on organizational priorities.
• Key differences were identified in spatial data accuracy, reference data coverage, and system flexibility.
• Results highlighted variations in integration potential, staffing needs, and funding requirements.

Conclusions:

• The developed framework empowers decision-makers in large organizations to invest wisely in geocoding systems.
• The evaluation provides a comprehensive approach to assessing geocoding platforms beyond simple accuracy metrics.
• This research aids organizations in selecting systems that align with their operational capabilities and strategic goals.
