📊 Since I have been working on flood modeling for over a year, I wanted to start the map challenge with the flood topic. This map shows where people were reported to be affected by major flood events between 1985-2010. The most affected regions include the US (Dallas, Pennsylvania), South America (Brazil, Bolivia), Africa (Burkina Faso, Gao, Botswana), Asia (Pakistan, India, Bangladesh), and Australia. Moreover, people in coastal cities were observed to be more frequently affected than the rest.

It may be the easiest theme of the challenge, but always make sure to avoid such common mistakes in cartographic designs:
-
Extra text is not always a good case! AVOID clusters of text, and use simple attribute labels where possible.
-
Unwanted colors: not all maps need colors, and sometimes unintentional use of colors can convey the wrong message. For instance, here, sequential choropleth colors are used based on ADM2 property, WHICH DOES NOT MAKE SENSE!

This is by far the most difficult day for me. Being a digital cartographer, I have only thought of making a map with a computer. For this day, I looked into previous year's challenges and loved how they used day-to-day things to create a map. I quickly looked around and saw some shining red beans in my kitchen, and the rest you can see 😂

Bright colors on dark canvas always fascinate me. So here's my take on visualizing a road network and a destination route. The map shows my daily travel route from my home in Shum Shui Po, to my campus, Hong Kong Baptist University. The road network in neon blue is shown for just Kowloon, in which the red lines show the route. The road network with the route was prepared using the OSMnx python package and was later edited in Adobe Illustrator.

For today's theme, I created hexagons in ArcGIS Pro (using the Generate Tessellation tool), resampled them in Google Earth Engine with Global Aridity Index (GAI) data, and visualized them in QGIS + Illustrator. Each hexagon has a circumradius of approx. 15 Km.
GAI is an important indicator because it provides a comprehensive visual representation of areas worldwide that experience varying degrees of aridity, helping researchers and policymakers understand and address water scarcity issues. Moreover, the aridity index is a crucial metric for assessing the availability of water resources and predicting potential drought-prone regions, enabling proactive measures for water management and conservation.

I have always admired animated maps/gifs for conveying time-series information. So, for the North American theme, I used the North American Drought Monitor (NADM) dataset in Google Earth Engine. The animated map shows that in 2023, North America experienced significant drought variations, with regions like California and the Great Plains facing severe water scarcity, impacting agriculture and increasing the risk of wildfires.
For designing the animated map, I first assessed the NADM dataset from Awesome GEE Community Catalog, and then exported individual maps with Orthographic projection using geemap.cartoee module. Later on, I finalized the maps in Illustrator and Photoshop.
Shout-out to Prof. Qiusheng Wu for including cartoee in geemap, and Samapriya Roy, Ph.D. for maintaining the Awesome GEE Community Catalog!

A few weeks ago, I saw an aerial image of this place on social media and was instantly in love with the beauty of its landscape. So for today's theme, I chose this place called Manaus, located on the banks of the Negro River in northwestern Brazil.
For preparing this map poster, I used Maxar basemap image for 2021 and edited them directly in Adobe Photoshop and then Illustrator. I intended to print this as a wall poster and therefore processed all data in 8K resolution, which resulted in around 200 MB of image size. Here, I am sharing the compressed version (~7 MB, and 300dpi). So, if you need that very high resolution, request it on GitHub, and I will happily provide it.

Nighttime light (NTL) data is vital for identifying areas affected by power outages, infrastructure destruction, and population displacement in war conflict situations. I used sequential choropleth colors to visually represent changes in light intensity and highlight active regions. Although I initially aimed to depict the NTL variation in current months, I could only access data up until September (NTL data is not available after September IDK why!).
Nevertheless, I am sharing all available data, including rasters, individual maps, and original timelapse gifs, in the hope that it contributes to a better understanding of conflict dynamics, aids humanitarian efforts, and informs policy decisions for peace and stability in the region.

Heat stress has become a significant global concern, impacting populations worldwide. In this analysis, I focused on Europe, examining the population exposed to heat stress at the ADM 0 level. While Europe may experience lower levels of heat stress compared to other regions, there are still populations within European states facing high levels of heat stress, as depicted in the bivariate population exposure map.
For analysis, I used Global Extreme Heat Hazard (5 year interval) layer provided by World Bank, and Total Population data provided by Worldpop. For analysis, I used geemap for zonal statistics, ArcGIS Pro for maps, Illustrator for editing and Photoshop for final gif. All the individual maps and materials are available below.

Am I the only one obsessed with neon color road networks on dark backgrounds 😂? I have been waiting for this day since the start of this challenge as I wanted to create this masterpiece map showing the dense road network in Lahore city. I am also planning to prepare this kind of map after the 30DayMapChallenge, so feel free to suggest some beautiful cities with prominent road networks.

So, for day 16 theme, I choose Australia, as the country has experienced devastating forest fires that have significantly impacted its ecosystems and communities. Various factors, including extreme heat, prolonged droughts, and strong winds, have fueled these fires. The frequency and intensity of the fires have increased, resulting in widespread destruction of forests, biodiversity loss, and wildlife displacement. From the map, it can be seen that between 2001 and 2023, 3882 forest fires have been recorded.
For analysis, I used Google Earth Engine in Geemap, and exported results in ArcGIS Pro, where I designed the map. Later on, I finalized the map in Adobe Illustrator.

Last year, I was awarded a PhD fellowship at HKBU and had to leave Pakistan. Interestingly, during the same year, Pakistan witnessed the highest recorded number of people (280,000 individuals) leaving the country, resulting in the highest migration rate ever documented in its history. Today, I wanted to explore the theme of migration and depict the flow of people in and out of the country.
Although I couldn't find the most up-to-date comprehensive databases, I came across some valuable resources in nature papers, which I decided to utilize for my work. The map presented here illustrates the migration rates with Pakistan as the origin country and various other nations as destinations. Additionally, the barplot highlights the top 10 countries with the highest percentage of migration flow, with Saudi Arabia and the United Arab Emirates leading the list.
To create these visualizations, I utilized open-source datasets from Nature papers (figshare), cleaned the data using Python's pandas library, and geolocated the information using ArcGIS Pro.

During the COVID-19 pandemic, significant changes in nitrogen dioxide (NO2) concentrations were observed globally. With lockdowns and travel restrictions, reduced industrial and transportation activities led to a noticeable decline in NO2 levels. So, for today's theme, I used Sentinel-5P NO2 data to visualize the trends in NO2 for the pre covid (2019) and during covid (2020) period. Overall, a decreasing trend is prominent from the visualization. This unprecedented reduction in NO2 levels provides a glimpse of the environmental impact of reduced human activity during the pandemic.

Recently, I saw a stunning map poster featuring the Taz River, and I was truly captivated by the breathtaking beauty of this landscape. To align with today's raster theme, I utilized a River Relative Elevation Model (REM) derived from the GLC-30 Digital Elevation Model (DEM) dataset. To evaluate the REM, I employed the RiverREM Python package and ultimately brought the poster to life using Illustrator. It was an incredible experience to combine data analysis and artistic design to showcase the magnificence of the Taz River.

When considering the theme for this project, the idea of exploring the north direction in 3D maps immediately came to mind. I've been intrigued by John Nelson's bathymetric diorama for some time now, and today I finally decided to give it a try. This visualization aims to showcase that in 3D maps, the north direction is not always at the top. For this particular visualization, I selected the Tonga Trench, located in the southwestern Pacific Ocean. It holds the distinction of being the deepest trench in the Southern hemisphere and the second deepest on Earth, surpassed only by the Mariana Trench. To create this map, I utilized ArcGIS Pro and Adobe Illustrator, following an incredible tutorial by John Nelson.
