Cadastral Plan Georeferencing
Aligning registry plans with current satellite context for preliminary planning
Historic parcel structure made comparable with today's built context
This workflow aligns scanned cadastral and sectional plans with present-day satellite imagery using roads, building footprints and other identifiable features as control references. The transparent overlay supports preliminary comparison of parcel structure, access, easements and built form.
Registry sheets and contemporary imagery use different scales, orientations and levels of certainty. The useful output is not a false claim of survey accuracy, but a traceable planning aid that makes discrepancies and questions visible.
We completed source-plan review, control-feature selection, georeferencing, transparent overlay design and planning interpretation.
- Preserve the original registry plan as the traceable source
- Identify stable roads and built features as preliminary control references
- Align and test the plan against satellite context at multiple scales
- State the limits of the overlay and flag where licensed survey control is required
- Georeferenced registry plan
- Transparent satellite overlay
- Parcel and access comparison
- Preliminary planning interpretation
- Old paper records translated into a usable GIS layer
- Spatial uncertainty communicated rather than concealed
- Planning analysis separated clearly from legal survey work
Bring this capability to a live brief.
Site planners, property teams and development consultants often need to compare old registry information with current access and built form before commissioning survey work. We create an indicative evidence base and define the questions that formal verification must answer.
