My personal take on the fourth week of the #30DayMapChallange, a daily social challenge aimed at designing themed maps every day of November.
Since 2019, the geographic information systems (GIS) and spatial analysis community has been pretty busy every November, thanks to a fun challenge called #30DayMapChange. Each year, this challenge has a thematic schedule, proposing a theme that should be the main guideline for the map display that will be published on that particular day. While predefined daily themes certainly place a limitation on the creative mind, they also help participants find mutual interests, share data sources, and express individual styles visually and technologically.
Here, I would like to briefly summarize my fourth (and final) week of this challenge, detailing and showing the different maps I created, usually in Python using various spatial analysis tools and geospatial data.
In this article, all images were created by the author.
I have struggled a lot with this piece, both in terms of theme and imagery. In the end, I abandoned my training in Physics and decided to plot the Earth’s magnetic field with its Main field declination lines. These lines, like magnetic poles, can be positive or negative. He earth magnetic The north pole is defined by these lines, which are not always up. It is moving! In recent years it began to migrate from the Canadian Arctic towards Russia at a speed of several kilometers per year.
My first 3D map, so I kept the data relatively simple and opted for central Budapest, particularly District V and District VI. in Pest and visualized the height profile of the building based on ATLO Budapest Open Data Atlas. As for the technical part, I used Python as usual and finally learned the basics of Pydeck to create this piece. Enjoy the interactive version hereevery building…
