A visual language for technical systems
e² is a symbol and pattern design system for environmental science and engineering. It provides a consistent framework for building, documenting, and applying technical visual assets across domains.
Precision by Design
Built on a strict 24×24 grid with a 2px stroke system for consistent, scalable symbols across UI, documentation, and technical workflows.
Semantic Symbols
Each symbol represents one defined concept using controlled primitives, enabling fast recognition and consistent interpretation across domains.
Pattern-Based Encoding
Patterns represent continuous information such as flow, density, direction, structure, and spatial zones.
Designed for GIS
Built with QGIS, ArcGIS, scientific visualization, and engineering workflows in mind.
System Architecture
The system separates construction rules, symbol semantics, pattern logic, and tool integration so each part can scale independently.
Foundations
Grid, stroke, radius, spacing, and SVG production rules.
Symbols
Discrete representations of objects, systems, and concepts.
Patterns
Repeatable visual encodings for areas, fields, and processes.
Integration
Usage in GIS, design tools, documentation, and applications.
Built for real-world technical workflows
The system is intended for researchers, engineers, GIS users, designers, and software teams who need precise visual representation instead of decorative iconography.
Marine Science and Oceanography
Hydrography and Bathymetry
Engineering Software
Technical Documentation
QGIS, ArcGIS, Figma, Illustrator, and web applications
Planned asset formats
The system is designed around clean SVG assets first, with additional formats planned for design, GIS, and engineering workflows.
