Ireland was chosen for the theme (Europe) of the 2023 #30daymapchallenge and it is the second-largest island of the British Isles, and the third-largest in Europe.
The map features European roads (E-roads) and connections between built-up areas. In addition to main routes, it includes roads necessary for a fully connected transportation network, such as direct links between areas or routes to isolated places like harbors and airports. Within built-up areas, the map focuses on main roads, ensuring clarity and ease of navigation.
All roads are depicted with a single line, regardless of their size or number of lanes. This dataset is made available by Tailte Éireann.

Throughout the 2023 #30daymapchallenge, I encountered various OSM maps and likely explored most of the methods for acquiring data from sites supported by OSM. I became interested in automating this workflow to obtain a similar map for the challenge theme. I came across Prettymaps, a #Python package for drawing maps with customizable styles using OpenStreetMap data crated by Marcelo de Oliveira Rosa Prates. It is created using the osmnx, matplotlib, shapely, and vsketch packages. The documentation on GitHub provided a smooth experience, outlining the various steps to create and customize OSMs.
I also discovered the webapp version (Prettymap) developed by Christoph Rieke which has improved features on speed and adapted configuration to interface with the webapp.

Mount Kilimanjaro, situated in the Kilimanjaro Region of Tanzania, is a dormant volcano characterized by three distinct volcanic cones: Kibo, Mawenzi, and Shira. As the tallest mountain in Africa and the highest single free-standing peak above sea level globally, it reaches an impressive elevation of 5,895 meters (19,341 feet) above sea level, towering approximately 4,900 meters (16,100 feet) above its plateau base. This volcanic giant holds the distinction of being the highest volcano not only in Africa but also in the Eastern Hemisphere.

This visualization was created from the NIWA's bathymetry model of New Zealand. With a 250m as the original resolution, I clipped out portions of the model to focus mainly on New Zealand. This represents a significant advancement in our understanding of New Zealand's underwater landscape. Compiled from various sources including coastal charts, digital soundings archive, and multibeam data from both national and international surveys, this model is a comprehensive representation of the underwater terrain- NIWA Geospatial Data

During the 2023 #30daymapchallenge, I discovered one concept about north arrows on maps through a comment from @Mirza Waleed. Not all maps demands north arrows and that decision depends on the kind of data the creator is visualizing (in terms of the extent/area of the place) and more importantly the type of projection being used for the visualization.

During the 2023 #30daymapchallenge, this map (elevation in meters) was created using the Contour Polygon tool in #QGIS under the theme, Minimal- less is more.
Contour polygons in QGIS refer to the process of generating polygon features from contour lines, which are lines representing points of equal elevation on a map. These polygons are created by connecting the contour lines to form closed shapes, allowing for the visualization of areas with similar elevation levels.

Under the theme, Dot of the 2023 #30daymapchallenge, this map was created to visualize the pubs in UK. In my search for data, I found the GetTheData website It's all about organizing UK open data into location-based dashboards. What's really cool is that it not only surfaces the available data but also provides clear signposts to the original sources.
One of the standout features is the GetTheData panel that accompanies each dataset they publish. This panel explains exactly where you can access the data and view its license. It's incredibly user-friendly and a great resource for anyone interested in exploring open data in the UK.
I've found it super helpful, and I think you all will too. Check it out when you get a chance!

Is this a chart or a map? In thematic maps, you can't always tell. This features an article I read about Japanease Season.
Japan's climate, as outlined by the Japan Meteorological Agency, showcases a diverse range of weather patterns across its regions. From subarctic conditions in the north to subtropical climates in the south, Japan experiences four distinct seasons.
The climate varies between the Pacific and Sea of Japan sides, with northern Japan witnessing warm summers and freezing winters, characterized by heavy snowfall in mountainous and coastal areas. Eastern Japan, on the other hand, endures hot and humid summers alongside cold winters, with significant snowfall in specific regions.
Moving westward, Japan experiences very hot and humid summers, with temperatures occasionally soaring above 35°C, while winters are relatively moderate. The southern regions of Okinawa and Amami enjoy a subtropical oceanic climate, featuring warm and humid summers and mild winters, with temperatures rarely exceeding 35°C.
This climatological data, based on averages from the period of 1981-2010, sheds light on the diverse and contrasting weather conditions found across Japan's various regions.

The day's task for the 2023 #30daymapchallemge was about Population. I decided give this theme to my motherland, Ghana and visualize the population density from the available WorldPop Hub #geodatabase.
The data is available for download in Geotiff and ASCII XYZ formats, this dataset offers insights into population distribution at a resolution of 30 arc (about 1km at the equator). Utilizing a Geographic Coordinate System (WGS84), the data provides information on the number of people per square kilometer, derived from country totals adjusted to align with official United Nations population estimates from the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat (2019 Revision of World Population Prospects).
