Data Access
Provided by 
NadirEO Data Access is the platform’s unified gateway to Earth data, providing resilient, on-demand access to a broad catalogue of more than 200 open sources — spanning far beyond satellite imagery. Alongside optical and radar missions such as Sentinel-1, Sentinel-2, and Landsat, the service reaches climate and weather reanalysis, elevation and terrain models, land cover and land-use datasets, vegetation and biomass products, population and built-environment layers, and a wide range of environmental and geophysical datasets.
Built on cloud-native geospatial standards, the service discovers data through STAC catalogues and reads directly from public cloud storage, returning only the area and variables requested rather than depending on the rate-limited APIs of individual providers. Users simply select the dataset, area of interest, time range, bands or variables, and output format; the service transparently handles spatial clipping, multi-scene mosaicking, format conversion, and reliable delivery at scale, combining unrestricted free sources with a managed queue for rate-limited archives.
Fully integrated with the NadirEO ecosystem, Data Access acts as the data foundation for the platform’s application modules and services — from super-resolution and flood delineation to hazard assessment — feeding analysis-ready data directly into automated Earth Observation workflows, or delivering it to your own tools and pipelines through a developer-friendly API. By removing the complexity of multi-source data retrieval, it lets teams focus on analysis and decision-making rather than data logistics.
