Project Hub ychenzgithub
A curated collection of wildfire satellite tools, spread simulation metrics, deep-zoom historical cartography, GeoGuessr meta guides, and algorithms.
Featured Web Applications
Interactive platforms built with modern web tech, covering deep-zoom cartography, GeoGuessr meta tools, food discovery, cipher education, Rubik's Cube tutorials, tree and wildflower identification, and classical music appreciation.
Historical Map Appreciation Platform
An ultra-high-resolution deep-zoom platform for exploring historical maps. Zoom into millimeter-level pyramid tiles of Matteo Ricci's Kunyu Wanguo Quantu (1602) and Martino Martini's Novus Atlas Sinensis (1655), with historical layer annotations for an immersive viewing experience.
GeoGuessr Knowledge Hub & Quick Reference
A global GeoGuessr meta identification guide and review system distilled from real game notes. Covers Street View camera generations, utility poles, bollards, car and antenna meta, and a detailed interactive atlas of countries and regions to help competitive players pinpoint locations fast.
Irvine & Orange County Asian Food Map
An interactive map of 200+ Asian restaurants, boba and dessert shops, and supermarkets across Irvine and nearby Orange County cities (Tustin, Costa Mesa, and more), with category filters and spatial search.
Codebusters Cryptography Training Center
A training platform for Science Olympiad Codebusters (Division B, 2026–27), with tutorials for all 13 cipher types, unlimited practice generators, timed speed drills, and mock tests.
Rubik's Cube Guide: Beginner to CFOP
A bilingual Rubik's Cube tutorial: notation, the layer-by-layer beginner method, CFOP (F2L, OLL, PLL), the 2×2, and 4×4 reduction with parity. Every case diagram is generated from its algorithm, and every algorithm plays on a 3D cube.
Tree ID: Photo Guide to Identifying Trees
Learn trees by whole tree, leaf, flower, fruit and bark: a photo atlas of 92 common trees, SciOly Forest Finds species with identification keys and look-alikes, botany basics, conifer classification, and city tree maps.
Wildflower ID: Photo Guide to Wildflowers
61 wildflowers of California, gardens and the Canadian Rockies with photos, ID features and bloom calendars from iNaturalist records, plus look-alike pairs, flower anatomy, where to see wildflowers and a quiz.
Classical Music Collection: 55 Masterworks
Curated collection of 55 timeless classical masterworks spanning Baroque, Classical, Romantic, Impressionist, and Modern eras, with embedded playback and program notes.
Wildfire & Spatial Computing
Open-source computational toolkits and data pipelines for satellite fire monitoring and spatial spread benchmark metrics.
GFED5NRT · Global Near Real-Time Fire Emissions
Combines VIIRS 375m satellite active fire detections with GFED5 region- and vegetation-specific effective fire area (EFA) and fuel consumption (FC) scalars to automatically generate near real-time global burned area and chemical species emissions on a 0.25° grid.
- Automated daily retrieval of Suomi-NPP / NOAA-20 active fire detections
- Rigorous multi-species emission factor (EF) matrix conversion
- End-to-end cloud sync and global spatiotemporal mapping
FireSpreadIndices · Spread Simulation Benchmark
A Python benchmark library for evaluating the spatial agreement between simulated wildfire spread and observed fire perimeters. Includes overall agreement metrics (IoU, Dice, SDI, ADI, SSIM) and over-/under-prediction decomposition.
- Supports both vector polygons and binary/continuous raster grids
- Complete spatial metrics for fire spread shape and area deviation
- Reproducible Jupyter test workflows and visualizations
