DiKnow TechnologiesUK / GhanaSite Plan Spatial Verification for Africa*
Site Plan Spatial Verification for Africa*.
Making land ownership clear, visible and verifiable. SPV transforms information contained in paper cadastral and site plans into mapped evidence, helping people and organisations identify potential location, boundary, size and environmental risks before they become costly disputes, losses or delays.

✓ Spatial relationship made visible
Earlier risk identification
Turning site plans into clearer, safer land decisions.
Land-related decisions can expose individuals and organisations to serious loss and disruption. SPV provides an early, clearer understanding of the plan evidence so concerns can be investigated and preventive action taken before they escalate.

Document-First Verification—Fieldwork When Justified.
Where a legible and sufficiently complete old or new site plan is available, SPV can ordinarily begin without an immediate return to the land. The submitted plan is first preserved and analysed exactly as presented, creating an auditable record of the location, boundary, size and surrounding environment it purports to represent.
This avoids automatically incurring the cost of a repeat site visit before the existing evidence has been understood. It also prevents later measurements or interpretations from obscuring what the original plan actually showed.
Analyse
Reconstruct the parcel and assess internal consistency, spatial coherence and apparent risk indicators.
Escalate
Recommend targeted searches, beacon recovery, site inspection or resurvey when the findings or institutional requirements justify it.
Original-plan evidence
Preserved and assessed as a distinct evidential layer.
Subsequent field evidence
Separately dated, recorded and compared with—not substituted for—the original plan.
Africa-wide capability*
One verification approach. Adapted to each country.
African cadastral and site-plan systems use different grids, coordinate reference systems, survey conventions and area units. SPV applies the appropriate country context while maintaining one consistent and defensible verification workflow.
West AfricaEast AfricaCentral AfricaSouthern AfricaNorth Africa
Country-specific reference systems
The appropriate grid and CRS are selected for the relevant national or regional mapping context.
Local area conventions
Acres, hectares and formats such as ha / a / ca can be reported to match local professional practice.
Consistent spatial evidence
Location, overlap, size and environment are examined through the same clear SPV framework.

How SPV works
Analyse the existing plan first. Escalate with purpose.
A preliminary SPV assessment begins with a clear scanned copy of a cadastral or site plan. The structured, country-aware workflow makes the submitted evidence easier to understand, compare and act upon before additional field evidence is introduced.
01Preserve the submitted evidence
Review the plan
Record and examine the coordinates, bearings, distances, scale, stated area and relevant survey information exactly as presented.
02Plan data → digital boundary
Reconstruct the parcel
Digitally reconstruct the boundary in the appropriate country-specific grid or coordinate reference system.
03Boundary → mapped context
Project & assess
Project the parcel onto suitable imagery or basemaps and assess Location, Overlap, Size and Environment.
04Findings → focused next action
Compare & report
Compare other plans where available, identify apparent inconsistencies and report whether targeted professional follow-up is justified.
✓SPV turns hard-to-read plan data into clearer, measurable and defensible spatial evidence.

Key advantages
Earlier clarity. Better-focused action.
SPV helps decision-makers understand the plan they already have, identify where risk may lie and determine the most proportionate next step.
Faster preliminary assessment
Begin investigating a land parcel from the submitted plan before committing to more extensive fieldwork.
Clear real-world context
See where the reconstructed parcel falls in relation to satellite imagery, roads, buildings and surrounding development.
Measurement verification
Examine the parcel’s area, shape, bearings, distances and other measurable characteristics.
Early conflict detection
Identify potential overlaps, gaps, displacement, encroachment, competing claims and possible plan inconsistencies.
Better-focused investigation
Use preliminary findings to guide site inspections, field surveys, official searches, investigations and legal preparation.
Stronger risk governance
Give decision-makers clearer visual evidence for lending, investment, development, dispute management and litigation.
Who SPV supports
One verification system.
Multiple high-stakes uses.
SPV gives decision-makers a common spatial view of the submitted evidence—so important questions can be identified before registration, lending, development, investigation or litigation progresses.
01Evidence & investigation
Legal, judicial & investigative
Support lawyers, litigants, courts, the judiciary, police and investigative authorities with clearer spatial evidence for disputes and enquiries.
02Risk governance
Banking, insurance & risk
Help banks, collateral teams, insurers and risk professionals examine the stated location, extent and potential overlap of land before exposure grows.
03Professional review
Surveying & land administration
Give surveyors, Lands Commissions, land authorities and other professionals a preserved plan-first analysis to guide focused technical follow-up.
04Land stewardship
Landowners & customary authorities
Help purchasers, landowners, traditional authorities, stools and families see what a submitted plan represents before later evidence is introduced.
05Investment due diligence
Development & investment
Support developers, institutional investors and diaspora property investors with early-stage screening before acquisition or development commitments.
06Public decisions
Government & public oversight
Provide regulators, local authorities and public agencies with a clearer common view of plan evidence for informed decisions and oversight.
Featured professional briefing
SPV helps lawyers see the land evidence behind the paper.
For plaintiffs and defendants alike, spatial verification can reveal the questions that should be asked earlier—before a defective location, overlap or composite plan shapes the direction of a case.
Understand the plan
Clarify true location, acreage, overlap, encroachment and surrounding features.
Prepare the litigation
Support pleadings, cross-examination, case theory and expert evidence.
Detect risk earlier
Identify shifted plans, duplication, double allocation and spatial uncertainty.
Ghana civil proceedings
Independent spatial analysis for composite plans under Order 26 of C.I. 47.
SPV can cross-check a court surveyor’s composite plan against the original site plans, help counsel frame precise technical questions and support a suitably qualified party expert where the court permits.
- Verify coordinates, bearings, distances, scale, orientation, acreage and overlap.
- Identify omissions, displacement, plotting or coordinate-entry errors.
- Preserve a transparent analysis trail for professional and judicial scrutiny.
