Welcome to Stellar Portal—the best starting point for professors, government teams, and NGOs to explore data quickly, understand what’s available, and take action. Think of Stellar as a federated front door to many Data Planets: distinct, provider-managed data “universes,” unified into one discoverable, user-friendly experience.
From “What data do we have?” to “Here’s the evidence.”
Stellar shifts you from aimless browsing to question-driven exploration, giving classrooms, policy work, and social programs citable evidence.
One place, many providers.
Explore multiple Planets in a single interface—no more hopping between portals, formats, or permissions.
Friendly for non-engineers.
Plain-language search, clear fields, and time/geo coverage summaries help you get value without a data engineering team.
From exploration to insight in minutes.
A conversational interface plus AI-assisted retrieval helps you quickly surface related datasets and move toward an aligned insight.
