The Problem

Geospatial data licensing is a minefield. Datasets like OpenStreetMap, Sentinel-2, Landsat, and NAIP each carry different license terms — and combining them in a single project can create legal conflicts that aren't obvious until it's too late.

A GIS professional publishing a derived dataset, a developer building a geospatial app, or a compliance team auditing data usage all face the same question: what can I actually do with this data?

There was no single tool that answered that question clearly.

What We Built

"Every layer has a contract."

GeLi Navigator is a free, open-source geospatial data licensing tool. It helps users understand license terms, check compatibility between datasets, and generate correct attribution — all in plain language.

License Lookup

Search datasets by name, provider, or description. Get plain-language license summaries with color-coded permission badges.

Compatibility Checker

Select two or more datasets and get a pairwise compatibility matrix with an overall verdict. 12 licenses, 66 rules — deterministic and auditable.

Attribution Generator

Auto-generate correct combined attribution for multi-dataset projects in plain text, HTML, or Markdown. No more guessing.

Dataset Registry

Browsable catalog of geospatial datasets with license metadata, filterable by type and coverage. Growing through community contributions.

Magic Link Auth

Lightweight email-based authentication. No passwords, no OAuth complexity — users get in fast and stay signed in.

Community Contributions

Authenticated users can submit new dataset metadata for review, keeping the registry growing beyond what any single team could maintain.

Brand identity created in parallel with development: dark theme with teal accent, modern geometric typography. The design is professional but accessible — built for daily use by working professionals, not a tech demo.

GeLi Navigator went from concept to deployed, production MVP in approximately one week.

That includes the application, brand identity, SEO implementation, infrastructure provisioning, and production deployment with auto-HTTPS. This is what SSLab does: identify a real problem in a domain we know deeply, choose the right tools, and ship fast without cutting corners.

What's Next

Community Growth

Adoption across GIS professionals, developers, and compliance teams. Expanding the dataset registry through community contributions.

AI Compatibility

AI-powered analysis for licenses not yet covered by the rule engine — extending coverage beyond the current 66 rules.

Open Source

Available on GitHub. Contributions welcome.
