OAS Geospatial Consults is a Lagos-based surveying and geospatial practice. We exist because too much land data in Nigeria is undocumented, disputed, or simply out of date — and every one of those gaps eventually becomes someone's problem at the worst possible time.
To become a trusted African geomatics and geospatial consultancy with international relevance, recognised for transforming complex land, engineering and spatial challenges into reliable information that enables confident decisions and sustainable development.
To solve land, engineering and development challenges through precise surveying, intelligent geospatial solutions and professional technical expertise. We deliver reliable spatial information that supports planning, design, construction, property investment and infrastructure development for clients in Nigeria and beyond.
Land, infrastructure and development decisions depend on accurate and dependable spatial information. OAS Geospatial Consults exists to reduce uncertainty by transforming field observations, geospatial data and technical analysis into reliable information for planning, design, construction, investment and asset management.
We combine professional surveying practice with modern geospatial technologies to help clients manage risk, make informed decisions and deliver projects with confidence.
Every assignment is approached with appropriate survey control, verification, quality checks and professional judgement. Our work is prepared to meet relevant technical, professional and regulatory requirements, producing spatial information that clients can rely on.
We structure survey and geospatial information for continued use beyond a single drawing or report. Where appropriate, project data can support GIS, engineering design, construction, asset management and future development decisions.
Reliable geospatial information carries professional responsibility. From land and engineering projects to construction, infrastructure and spatial planning, clients depend on accurate measurements, sound professional judgement and technically robust deliverables. OAS Geospatial Consults combines professional expertise, disciplined survey practice and modern geospatial technologies to deliver information that can be trusted throughout the project lifecycle.
Our work is guided by professional judgement, technical competence and a clear understanding of the responsibilities attached to surveying, geomatics and geospatial information.
Our capabilities span cadastral and topographical surveying, engineering surveying, GIS, construction support, spatial analysis, hydrographic applications and geospatial consultancy.
Projects are planned, executed, verified and delivered with appropriate survey control, technical checks and quality assurance, while considering applicable regulatory, project and client requirements.
We develop structured spatial information for continued use across GIS, CAD, engineering design, construction, asset management and future project development, not simply as information confined to a single drawing or report.
Our practice is grounded in Nigeria’s professional and regulatory environment while embracing modern geospatial workflows, interoperable data and professional delivery standards suited to multidisciplinary and cross-border collaboration.
