Evidence first
We say what the data shows and how confident we are in it. Our methods and sources are documented so others can check the result.
About us
Vertical Aspects is a GIS and remote sensing consultancy, founded in 2018 and based in Port Harcourt, Rivers State.
Daniel Obriango founded Vertical Aspects in 2018, after working in GIS in the United Kingdom and Nigeria. He saw the same problem again and again: organisations held plenty of data, but had no way to read it spatially. Decisions about where to allocate resources, where to focus attention and what to do next were being made without the location evidence that could inform them.
We set out to close that gap. We collect, analyse and present geographic data, then customise the output to the client, whether that means an interactive map, a geodatabase, charts or a written report. We build it to fit the systems the client already has.
Since then we have worked for government agencies, non-profit organisations and private companies in oil and gas, power, manufacturing and consulting, including Brass LNG, Chevron, PHEDC and the Rivers State Government.
Much of our work sits where environment and communities meet: informal waterfront settlements facing demolition, island communities missing from official maps, and the land and water affected by oil and gas operations. In places like these, a good map shows who is affected and what is at stake, and gives communities and decision-makers a shared set of facts.
That is why social-impact work leads our portfolio. 7 of our 8 published projects are in this area. See our projects.
We say what the data shows and how confident we are in it. Our methods and sources are documented so others can check the result.
Field and community mapping is done alongside residents, and we ask consent before we photograph or record people.
Outputs fit the client's existing tools and workflows, and we design them to adapt as needs change.
