Digital Earth Africa’s Data Cube: Who Owns the Continent’s Satellite Archive?

Digital Earth Africa describes its mission as processing openly accessible and freely available data into decision-ready products for the continent, working closely with the AfriGEO community and responsive to African priorities. That is a real achievement. It is also a governance arrangement that deserves scrutiny, because the archive it assembles is not owned by the continent in any ordinary sense of the word.

The data cube is a continental-scale, analysis-ready Earth observation archive. It incorporates historical to near-real-time data on Africa’s coastlines, waterbodies and land expanse, and it is delivered through tools including DE Africa Map, dashboards, metadata explorers and OGC web services. The question of ownership is not a technical footnote. It determines who can decide what the archive contains, who can access it under what terms, and what happens if a foreign operator changes its mind.

What the data cube actually is

Digital Earth Africa is not a satellite operator. It is a processing and service layer. Its own materials state that it “processes open data to meet the continent’s needs” and that its mission is to “process openly accessible and freely available data to produce decision-ready products.” The archive is assembled from satellite imagery that is already open, then harmonised, corrected and made analysis-ready for African users.

That distinction matters. The raw imagery comes from foreign-operated satellite systems. The value added — calibration, cloud masking, tiling, time-series assembly, user tools — is produced by Digital Earth Africa and its partners. Ownership of the archive is therefore layered: the upstream pixels are not African property, the downstream products are governed by the programme’s own arrangements, and the infrastructure that holds the whole thing sits in a jurisdiction that is not specified on the public homepage.

The treaty layer: what international space law does and does not say

The five United Nations treaties on outer space, concluded through the Committee on the Peaceful Uses of Outer Space, establish the basic framework. The Outer Space Treaty, adopted by General Assembly resolution 2222 (XXI) and in force since 10 October 1967, provides that outer space is not subject to national appropriation and that activities are to be carried out for the benefit of all countries. The Registration Convention, adopted by resolution 3235 (XXIX) and in force since 15 September 1976, requires states to register objects launched into outer space. The Liability Convention, adopted by resolution 2777 (XXVI) and in force since 1 September 1972, addresses damage caused by space objects.

None of these instruments says who owns a continental data cube. They regulate state activity in outer space, not the intellectual property or contractual arrangements around derived data products. The Remote Sensing Principles, adopted by General Assembly resolution 41/65 of 3 December 1986, are the closest thing to a relevant norm. They address remote sensing for the benefit of all countries and provide for access to data on a non-discriminatory basis. But they are principles, not a treaty, and they do not create an enforceable ownership claim over an archive assembled from open data.

The practical consequence is that African states cannot point to a treaty article and demand control of the data cube. The legal architecture that governs the archive is contract, licence and institutional arrangement — not space law.

The ITU layer: spectrum and orbital slots as upstream dependencies

The International Telecommunication Union’s Space Services Department implements the regulatory and technical procedures of the Radio Regulations for space systems, earth stations and radio astronomy stations. It processes frequency assignment notices submitted by administrations, establishes coordination requirements, and records assignments in the Master International Frequency Register. It also monitors the deployment of satellites in geostationary and non-geostationary orbits and assists administrations with harmful interference cases.

This is where African states have real leverage, and where the data cube’s upstream dependency becomes visible. Earth observation satellites need spectrum and orbital positions. Those are allocated through ITU processes in which administrations file notices, coordinate with other administrations, and accept cost-recovery obligations. A state that does not file, coordinate and protect its assignments is not a full participant in the system that makes the imagery possible.

The ITU framework is intergovernmental. African administrations can file, coordinate and defend their assignments. But the satellites that feed Digital Earth Africa are largely filed and operated by other administrations. The continent’s access to the resulting imagery depends on the licensing decisions of foreign operators and the open-data policies of foreign governments. That is a structural asymmetry, not a legal violation.

Who owns what: a layered answer

The honest answer is that ownership is distributed across four layers, and African institutions control only some of them.

Upstream imagery. Owned or controlled by the satellite operators and the administrations that filed for their spectrum. Digital Earth Africa’s own description confirms it uses openly accessible and freely available data, which means the programme is a consumer of open data, not the owner of the source pixels.

Processing and derived products. Produced by Digital Earth Africa and its technical partners. The programme’s governance arrangements, not a treaty, determine who can use these products and on what terms.

Infrastructure. The servers, storage and compute that hold the archive. The public homepage does not specify where this infrastructure sits or under whose jurisdiction. That is a gap worth naming, because jurisdiction determines what legal process can compel access, deletion or continuity.

Institutional oversight. The African Union’s Agenda 2063 provides the continental policy frame, and AfriGEO provides the community coordination. But neither is described in the retrieved materials as holding title to the archive or as having unilateral authority over its contents.

Why this matters now

Continental-scale environmental monitoring is becoming essential infrastructure. Flood risk mapping, water scarcity tracking, land degradation monitoring and coastal erosion analysis all depend on continuity of the archive. If the upstream open-data policy changes, or if a foreign operator restricts access, or if the infrastructure provider changes its terms, African users have limited recourse.

The Remote Sensing Principles call for access on a non-discriminatory basis. They do not guarantee permanence. The Benefits Declaration, General Assembly resolution 51/122 of 13 December 1996, calls for international cooperation to take particular account of the needs of developing countries. It is a declaration, not a mechanism.

The gap is institutional. African states have a seat at the ITU, where spectrum and orbital positions are coordinated. They have a seat at COPUOS, where space law is debated. They do not have a clear legal instrument that gives them control over a data cube assembled from foreign-operated satellites and processed through arrangements they do not unilaterally govern.

What practical steps would change the position

These are recommendations, not findings. They follow from the structural analysis above.

Publish the governance map. Digital Earth Africa should state plainly where the archive is hosted, under whose jurisdiction, and what contractual terms govern continuity of access. Users cannot negotiate what they cannot see.

Negotiate continuity guarantees. African institutions should seek written commitments from upstream data providers and infrastructure hosts that access will not be withdrawn without notice and transition arrangements. This is a procurement and diplomacy task, not a litigation task.

Build sovereign processing capacity. The value added in the data cube is processing. If African institutions host and operate the processing layer, they control the derived products even when the upstream pixels remain foreign-owned.

Use the ITU process actively. Spectrum and orbital assignments are filed by administrations. African states that file, coordinate and protect assignments strengthen their position in the upstream system that makes Earth observation possible.

Clarify the AU’s role. Agenda 2063 provides the policy frame. It does not, on the retrieved materials, provide a title or control mechanism for the archive. If the African Union is to speak for the continent on data governance, the mandate and the instruments need to be explicit.

FAQ

Does Digital Earth Africa own the satellite imagery it distributes?
No. Its own materials state that it processes openly accessible and freely available data. The upstream imagery comes from satellite operators and the administrations that filed for their spectrum. Digital Earth Africa owns the processing and derived products, subject to its own governance arrangements.

Does international space law give African states a claim over the data cube?
No. The Outer Space Treaty, the Registration Convention and the Liability Convention regulate state activity in outer space. The Remote Sensing Principles address access to data but are principles, not a treaty, and do not create an ownership claim over an archive assembled from open data.

What does the ITU have to do with a data cube?
The ITU coordinates spectrum and orbital positions for the satellites that produce the imagery. African administrations participate in that process. The data cube itself is downstream of those allocations, which means the continent’s access depends partly on decisions made in a forum where it does have a seat.

Where is the archive hosted?
The public homepage does not specify the hosting jurisdiction. That is a gap. Jurisdiction determines what legal process can compel access, deletion or continuity, and users should ask for it to be disclosed.

What can African institutions do now?
Publish the governance map, negotiate continuity guarantees, build sovereign processing capacity, use the ITU filing process actively, and clarify the African Union’s mandate over continental data governance.

The bottom line

Digital Earth Africa is a genuine public good. It turns open satellite data into products that African policymakers, scientists and communities can use. But the archive is not owned by Africa in any enforceable sense. The upstream pixels belong to foreign operators. The processing layer is governed by programme arrangements. The infrastructure jurisdiction is undisclosed. The treaty framework provides principles, not control.

Ownership is not a slogan. It is a set of legal and institutional arrangements that determine who decides. Until those arrangements are named, negotiated and written down, the continent’s satellite archive will remain a service it uses rather than an asset it holds.
