Berkeley Environmental Health Explorer (BEHE)

A modern web platform for exploring and analyzing environmental and climate data on the UC Berkeley campus and beyond.

Features

• Interactive Campus Map: Visualizes Berkeley's tree inventory, air quality sensors, and overlays environmental data points on a dynamic map.
• Environmental Data Comparison: Compare air quality, tree diversity, and other environmental factors between campus locations.
• Data Search & Filtering: Quickly search, filter, and explore available datasets by property, category, or source.
• Robust Error Handling: Gracefully handles missing or incomplete data files and provides user-friendly notifications/fallbacks.
• Static Data Loading: Loads all data directly from static JSON/GeoJSON/CSV files for speed and reliability—no backend required.
• User-Contributed Datasets: Supports community-uploaded datasets for extensibility and collaboration.

Data Sources & Static Data Approach

• Berkeley City Tree Inventory (GeoJSON, 2013): Official tree census data for the UC Berkeley campus and city.
• AirNow API (Historical Air Quality): Hourly/daily air quality data for Berkeley, pre-fetched and stored as JSON using a Python script.
• User-Contributed/Community Data: Additional datasets in CSV or JSON format, uploaded or curated by users.

Note: All data is pre-compiled and placed in the public/data/ directory. The frontend loads these files directly—no backend or live API calls are required at runtime.

Technology Stack

• React (with TypeScript) — UI and application logic
• Vite — Fast development/build tool
• Material UI (MUI) — Component library and styling
• Plotly.js & react-plotly.js — Data visualization (charts, radar plots)
• Leaflet — Interactive mapping
• Custom TypeScript Types — Enforced type safety for all data and UI structures
• Python (for data pre-processing only; not part of the deployed frontend)

Getting Started

Prerequisites

• Node.js (v18+ recommended)
• npm or yarn

Installation & Development

1. Clone the repository:

   git clone https://github.com/oilsinwater/ueh-platform.git
   cd ueh-platform

2. Install dependencies:

   npm install

3. Start the development server:

   npm run dev

4. Visit http://localhost:5173 in your browser.

Data Files

• Place static data files in public/data/ (e.g., public/data/airnow/, public/data/processed/).
• To update air quality data, run the provided Python script and copy the resulting JSON into the appropriate directory.
