Which of the following is a method of using GIS in assessing the built environment?

Using datasets with objective built environment measures is a method for leveraging Geographic Information Systems (GIS) in assessing the built environment because it involves quantifiable data that can be mapped and analyzed to provide insights on various factors affecting public health, accessibility, and urban planning. Objective measures could include data on land use, population density, transportation networks, and green spaces, all of which can be spatially represented to reveal patterns and correlations.

This approach ensures that the assessments are grounded in measurable facts rather than subjective viewpoints, allowing for more accurate planning and policy-making. It is crucial to base assessments on objective data to formulate effective interventions and strategies that utilize the built environment to improve health outcomes and enhance public spaces.

The other options, while they may have their own relevance in different contexts, do not harness the full potential of GIS in evaluating the built environment as effectively as employing objective datasets.
