Question 1

What does Digital Earth Africa do?

Accepted Answer

Digital Earth Africa (DE Africa) is a continental-scale open data platform that makes analysis-ready satellite data freely accessible for the entire African continent, providing tools, datasets, and APIs that allow researchers, governments, NGOs, and developers to extract valuable insights from years of Earth observation imagery without requiring specialized remote sensing expertise or high-performance computing infrastructure. Backed by African governments and international development partners including the African Union, Digital Earth Africa addresses the fundamental challenge that satellite data — while publicly available — historically required substantial technical expertise and computing resources to process, making it inaccessible to most African organizations.

The DE Africa platform is built on the Open Data Cube framework and exposes satellite datasets as analysis-ready datacubes where each pixel contains atmospherically corrected, geometrically accurate surface reflectance values aligned across time. This means Nigerian data scientists and environmental analysts can query pixel-level time series data across Nigerian territory without the complex preprocessing normally required for raw satellite imagery. The Python API enables querying: "Show me the vegetation index (NDVI) for all farmland pixels in Kano State for every July from 2015 to 2025" — a query that would previously require months of data processing.

Water monitoring datasets from DE Africa include the Water Observations from Space (WOfS) dataset, which classifies every pixel in Africa as water or non-water based on Landsat and Sentinel-2 imagery analysis. For Nigerian flood monitoring platforms, this dataset provides historical flood extent mapping across Nigeria — enabling analysis of which areas in the Niger Delta, Benue Valley, and Sokoto Rima floodplains are repeatedly inundated and need permanent flood risk classification. The Waterbodies dataset monitors changes in the extent of lakes, reservoirs, and rivers over time.

Vegetation and land cover datasets support Nigerian agricultural and environmental monitoring. The Annual Crop Mask dataset classifies agricultural land across Africa, allowing Nigerian agricultural agencies to estimate cropland extent by state and track year-on-year changes in agricultural land use. The Fractional Cover dataset quantifies the proportion of bare soil, green vegetation, and non-green vegetation in each pixel, useful for monitoring rangeland health in the Sahel portions of northern Nigeria and detecting land degradation.

Coastline monitoring data from the Continental Coastlines dataset maps the African shoreline and tracks changes over time due to erosion, sedimentation, and sea-level effects. Nigeria's Atlantic coastline in the Niger Delta region is subject to intense erosion pressures due to oil infrastructure, wave action, and reduced sediment supply. Nigerian coastal management agencies and environmental researchers can use DE Africa coastline data to quantify erosion rates and identify the most vulnerable coastal communities.

The DE Africa Sandbox provides a browser-based Jupyter notebook environment where Nigerian developers and analysts can explore datasets, run Python code against the datacube API, and visualize results without any local installation. This browser-accessible development environment lowers the barrier to entry for Nigerian universities, research institutes, and NGOs that want to experiment with satellite data analysis without infrastructure investment.

Digital Earth Africa data and platform access are entirely free, funded as a public good by African governments and international partners. Nigerian government agencies, universities, research institutes, and civil society organizations can access all datasets without subscription fees, supporting evidence-based environmental management, agricultural policy, and climate adaptation planning across Nigeria.
