A Data-Driven Look Using JRC Global Surface Water, Landsat, and HydroRIVERS (1984–2024) Bangladesh is one of the most flood-affected countries in the world. Its landscape—woven by the Padma, Jamuna, Meghna, and hundreds of tributaries—is shaped each year by monsoon rainfall, upstream flows, and seasonal inundation. But how has flood exposure changed over time? And which regions experience the most persistent flooding? To answer these questions, I created a nationwide Flood Ex

A spatial map showing how climate stress (flood, drought, salinity, heat) intersects with major crop zones (rice, jute, tea, vegetables). Why this is unique Bangladesh has extremely diverse agro-ecological zones and is highly climate-sensitive. A composite map that blends multi-hazard climate layers with crop intensity gives a powerful way to visualize where agricultural systems are most vulnerable . What the map shows A national map with: 1. Crop Zones (from MODIS/ESA Landc

By: Zarrin Tasneem Florida is no stranger to severe weather. Between intense heat waves and some of the strongest hurricanes in history, Floridians live with a unique mix of climate risks. But how resilient are different parts of the state to these threats? To answer that, I built a simple yet powerful Resilience Map , using a data-driven score that blends multiple environmental and social factors. The goal: to help visualize which communities might be more vulnerable during

By Zarrin Tasneem Ever feel like you need a break from the heat, the traffic, or just the chaos of your city? What if you could map out the most relaxing place to escape using a mix of data science, satellites, and a little imagination? Welcome to the Blue–Green Escape Map , a Python-powered interactive tool that reveals the coolest (literally), greenest, and water-rich cities across the United States. This project started off as an experiment in blending geospatial data, en

Few natural forces have as much impact on the North Carolina coast as hurricanes. Every season, powerful systems sweep across the Atlantic, reshaping shorelines, testing infrastructure, and reminding us of the delicate balance between land and sea. The Hurricane and Coastal Surge Tracker is an interactive map designed to bring this story to life, merging historical hurricane tracks, active storm forecasts, and coastal tide data into one unified, real-time visualization. Trac

Across North Carolina’s diverse landscapes from the Appalachian headwaters to the coastal plains, rivers pulse with life, data, and risk. The Live River and Flood Watchboard brings those dynamics into view in real time, transforming raw sensor streams into an intuitive dashboard of river health and flood conditions. What It Shows The map combines two powerful, open data feeds: USGS National Water Information System (NWIS): real-time measurements of stream height and dischar

Every city tells a story, not only through its architecture or skyline. It’s in the quiet corners, the first snowfall, the park benches, the cafés, and the small details that become part of our own story.The Memory Map reimagines Toronto not as streets and buildings, but as a tapestry of lived experiences. Each point on the map represents a memory , plotted as an emoji, a 🌸 for peaceful walks in High Park, a ❄️ for that first snowfall at the Harbourfront, a 🌮 marking a fav

Turning City Data into a Playful Emoji Story What if you could read a city’s character not through symbols or charts, but through emojis? This Emoji Map of Toronto does exactly that, which is transforming urban data into a fun, thematic visualization using 🌳 for parks , 🏢 for offices , and 🏠 for homes . Concept Urban maps can usually feel technical and dense. The Emoji Map reimagines them as intuitive and expressive, which is a way to see the rhythm of the city at a gla

This interactive map explores the city of Toronto through time contrasting its daytime landscape with its nighttime illumination. Using a temporal swipe interface , the map allows users to slide between daytime satellite imagery (Esri World Imagery) and nighttime Earth observation data (NASA GIBS Black Marble) , revealing how urban form and light patterns intertwine across the metropolis. Data Sources Daytime : Esri World Imagery , which is a high-resolution composite of tr

In a city that never sleeps, calm can be as rare as quiet. Yet even within Toronto’s dense urban fabric, pockets of tranquility persist in parks, waterfront trails, or forested ravines. This Soundscape Map visualizes those hidden oases of calm through a geospatial analysis of relative noise levels across the Greater Toronto Area. What the Map Shows The heatmap above represents the relative calmness of the urban environment where areas with lower ambient noise or reduced urb

Mapping the Ride Toronto’s cycling network is expanding rapidly but not all routes are created equal. While some paths glide smoothly along the waterfront, others snake up steep ravines and hilly neighborhoods. To visualize these differences, this map highlights bike lanes across Toronto , color-coded by slope gradient , which is a key factor impacting effort, accessibility, and ride enjoyment. Using OpenStreetMap data for cycling infrastructure and elevation models from pu

Toronto is known for its vibrant urban forest, from High Park and the Don Valley to the quiet corridors of neighborhood parks. But how green is the city really? To answer this, I used Sentinel-2 multispectral imagery and Normalized Difference Vegetation Index (NDVI) analysis to map vegetation health across Toronto’s urban green spaces. What Is NDVI? NDVI is one of the most widely used vegetation indices in remote sensing. It leverages the difference between near-infrared (

Toronto’s public transit system, which is operated by the Toronto Transit Commission (TTC) is one of the most extensive in North America, carrying over 1.6 million passengers daily . The video, and map below highlights the flow of Toronto’s subway and streetcar lines , demonstrating the lifelines that keep the city moving every day. About the Map This interactive visualization displays the TTC’s subway and streetcar network using OpenStreetMap data. Each line is color-coded

Illuminating Toronto from Space Every night, satellites orbiting hundreds of kilometers above Earth capture a dazzling view of human activity. One of the most remarkable datasets comes from NASA and NOAA’s VIIRS (Visible Infrared Imaging Radiometer Suite) instrument. It records night-time light emissions from streetlights, buildings, vehicles, and even ships giving us a glowing fingerprint of urban life. This visualization focuses on Toronto , a vibrant city whose energy is

Stretching from Mississauga to Pickering, Toronto’s waterfront is more than a line on the map, it is a living gradient of vegetation, architecture, and atmosphere. This stretch along Lake Ontario captures how a modern city meets its natural edge, revealing the delicate balance between urban density and ecological space. Using Sentinel-2 multispectral imagery , I mapped vegetation patterns along the waterfront at a spatial resolution of ~20 m. The resulting NDVI (Normalized Di

Every summer, Montréal becomes a patchwork of heat and coolness, a living thermal mosaic shaped by buildings, trees, and pavement. Using Landsat 9 imagery and Google Earth Engine, I mapped surface temperature and vegetation to reveal the city’s Urban Heat Island (UHI) pattern. The red areas on the map mark neighborhoods where surface temperatures run hottest and vegetation is sparse such as downtown, industrial corridors, and dense residential zones. In contrast, the blue
