About this data

Is the analysis based on one-metre lidar?

The current analysis uses the national baseline elevation. A finer display grid does not create finer source detail, and underlying survey dates and quality vary.

Does low slope mean an area is buildable?

Slope describes terrain only. Grading, drainage, geotechnical conditions, access and permissions require separate investigation; the output is a screening estimate rather than a survey.
