Introduction

Sustainable Development Goals (SDGs) of the United Nations were set to provide solutions to global challenges such as climate change, poverty, food security, and protection of the environment. In order for these goals to be met, there is a need for quality data, and the best source of which is satellite data. But while some government and public agency financing has made the data accessible, much of it remains stuck in commercial satellite archives. Making these archives available would go a long way to advance SDG research and stimulate more effective global action.

The use of satellite imagery in SDG research

Satellite imagery is essential to monitor and measure many SDGs, such as:

Climate Action (SDG 13): Monitoring deforestation, carbon footprint, and global temperature deviation.

Life on Land (SDG 15): Measuring biodiversity, desertification, and land degradation.

Clean Water and Sanitation (SDG 6): Monitoring water bodies, drought, and the pollution index.

Zero Hunger (SDG 2): Mapping agricultural yield and food security risk.

Sustainable Cities and Communities (SDG 11): Urban development, disaster risk reduction, and infrastructure development.

Although open satellite data sources such as NASA Landsat and Sentinel provided by the European Space Agency prove to be handy, commercial satellites possess much clearer resolution, frequency of observation that is higher, and application-specified sensors having the capability of greatly improving the accuracy and contribution of research.

Restrictions in Access to Commercial Satellite Repositories

Though such vast amounts of potential reside in commercial satellite image repositories, these repositories aren’t available to use for pursuing SDG-type research freely owing to some obstructions:

1. Excessive Expenses

Commercial satellite imagery is expensive, with high-resolution data typically charged by the square kilometer. Most research institutions, particularly in developing countries, cannot meet the costs, and their ability to conduct in-depth SDG studies is therefore limited.

2. Licensing Restrictions

The majority of commercial satellite data vendors have stringent licensing terms that limit sharing, redistribution, and public use of the data. These limitations hinder large-scale collaboration and narrow the scope of SDG studies.

3. Data Fragmentation

Satellite images are shared between different commercial sources, and as such, combining data from a wide range of sources is not easy. Absence of one central point for access makes researchers struggle to access comprehensive datasets.

4. Technical Barriers

High-resolution image analysis and interpretation demand sophisticated computing facilities, expert computer software, and technical skills in remote sensing and geographic information systems (GIS). Such demands could deter small research teams and developing countries.

How Unlocking Commercial Satellite Archives Can Revolutionize SDG Research

Unlocking commercial satellite archives can release revolutionary value for SDG research:

1. Improved Data Accuracy and Coverage

High-resolution detailed images from commercial satellites can give more in-depth and localized information on environmental change, urbanization, and climatic impact, with improved policy guidance.

2. Accelerating Disaster Response and Monitoring

Routine imaging by commercial satellites enables near real-time monitoring of natural disasters, deforestation, and water shortages. This accelerates the response and reduces the damage caused by extreme weather events.

3. Increased Collaboration and Innovation

Open access to satellite archives would stimulate intergovernmental and interdisciplinary cooperation among governments, research institutions, and technology firms. This would create new solutions, including AI-based environmental monitoring and predictive analytics.

4. Increased Research Equity

Poor countries are generally not given access to cutting-edge technologies and information. Making commercial repositories for this are available to the public is a chance for scientists globally to collaborate on SDG solutions to create data-driven development that is more inclusive.

Strategies to Open Up Commercial Satellite Archives

Unbundling commercial satellite data involves strategic initiatives by stakeholders such as governments, private industry, and international organizations. The following are some of the possible strategies:

1. Public-Private Partnerships (PPPs)

Governments and international institutions can partner with commercial satellite firms to establish subsidized access programs for research related to SDGs. Programs such as the World Bank’s Open Data Partnership can be extended to commercial satellite imagery.

2. Data Grants and Licensing Reforms

Commercial satellite operators can launch data grant schemes with low-cost or no-cost imagery for SDG activities. More relaxed licensing models can also allow more data sharing between scientists.

3. Cloud-Based Open Platforms

Having cloud-based archives where commercial operators donate screened datasets for public research can democratize access. Google Earth Engine and Amazon Web Services (AWS) already have some open datasets and could have a greater rollout.

4. AI and Data Compression Breakthroughs

Using AI to mine useful information from sparse satellite imagery can limit reliance on costly full-resolution imagery. New data compression methods can also render imagery more available for researchers with constrained computational resources.

Success Stories in Open Satellite Data Initiatives

A few success stories have been realized already for opening satellite data for SDG research:

Digital Earth Africa makes satellite imagery free and available to aid sustainable development activities in the African continent.

Planet’s Education and Research Program awards non-profits and universities with grants of satellite imagery for humanitarian and environmental causes.

NASA’s Open Data Policy enabled researchers from all over the globe to access Landsat imagery for city planning, disaster relief, and climatic studies.

Up-scaling efforts like these with commercial satellite companies could expand SDG research capacity dramatically.

Conclusion

Releasing commercial satellite archives for SDG analysis is not just an option but a requirement. The challenges we face in responding to climate change, urban resilience, and global food security require the best data available. By breaking down obstacles such as cost, licensing barriers, and data fragmentation, commercial firms can be an essential contributor to speeding up the rate of accomplishment of the Sustainable Development Goals. By way of partnerships, policy reform, and innovation, we can ensure that high-resolution satellite imaging serves not corporations alone but all of humanity.

Going forward, it is necessary that the governments, the private sector, and the international scientific community come together to transform the data into a global common good propelling an efficient and secure future.
