How it works

Public infrastructure,
open and interoperable.

Arca was designed as public digital infrastructure: a common good that does not depend on a single institution to exist. Its architecture is organized into four layers, each addressing a specific challenge in Brazil’s environmental data.

LAYER 01

Preserve

Redundant copies protect historical records against loss, discontinuity and interruptions. Data that took decades to produce no longer depends on a single server or government.

LAYER 02

Harmonize

Each source speaks its own language. Arca standardizes formats, reference systems and vocabularies so data from different sources can be compared and combined.

LAYER 03

Integrate

Environmental, land and climate data can be queried together through open interfaces (APIs). Solution builders do not need to rebuild the underlying data from scratch.

LAYER 04

Make available

Ready-to-use views, APIs and datasets, with clear governance over who can access what. Transparency is the rule, and confidentiality is a justified exception.

Open source
Data sovereignty
Interoperability
Traceability

A digital common good

Open data and technology, built for the public interest.

Arca is developed openly. Follow the code, documentation and community contributions.
