DiKnow TechnologiesUK / GhanaSite Plan Verification for Ghana
SPV transforms the boundary information in paper site plans into georeferenced polygons—helping professionals verify Location, Overlap, Size and Environment.

The SPV system
A structured verification workflow makes the site plan easier to understand, compare and act upon—without replacing the role of the licensed surveyor, lawyer or relevant authority.
Receive the paper or scanned site plan, then digitise its boundary, coordinates and essential survey information.
Transform the coordinates and project the parcel onto satellite imagery so its real-world location becomes visible.
Test area, overlap, displacement, encroachment and spatial relationships against other plans or records.
Present clear maps, measurements, tables and findings for professional review, decisions and courtroom explanation.
Professional applications
SPV gives decision-makers a common spatial view of the evidence—so important questions can be identified before registration, lending, development or litigation progresses.
Compare disputed site plans, test composite plans and present map-led evidence in a form that is easier to examine.
Check the stated location, extent and overlap of land offered as collateral before risk becomes exposure.
Project plans on current imagery, compare boundaries and identify inconsistencies early in the transaction cycle.
See where a paper plan actually falls on the ground and obtain a clearer basis for professional follow-up.
Featured professional briefing
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.
Clarify true location, acreage, overlap, encroachment and surrounding features.
Support pleadings, cross-examination, case theory and expert evidence.
Identify shifted plans, duplication, double allocation and spatial uncertainty.
