30 Day Map Challenge 2025 - Days 6-12

Another week of my Gulf of Mexico 30 Day Map Challenges. Last week's are here.

Day 6 - Dimensions

The prompt “dimensions” can mean height, depth or multidimensional data. Since my focus is on a body of water, I went with bathymetry (water depth) using the same data from Day 5 but rendered with an attempted 3D look. 3D is definitely a weakness of mine and it shows here.


Day 7 - Accessibility

Again, here’s a prompt that can mean many things. I went with public beach access. The data came from a couple of different Google Map queries but it seems very incomplete, especially in Mexico.


Day 8 - Urban

This challenge should ideally be a learning experience for me and all of us. Veracruz is a large city, regional center and significant port that I know little about. Here is a map showing some of the city’s amenities. The data is from OpenStreetMap. I will be revisiting this for my Day 14 map.


Day 9 - Analog

I made a cut paper map of the Gulf of Mexico. Here it is presented with the land on top of a glass coffee table at my mother’s apartment against a piece blue fleece and the water piece in the back.

Day 10 - Air

I took an air quality map from PurpleAir and mixed and expanded the colors to try and present a more regionalized picture of air quality. The problem with that data is that because there are many fewer sensors in Mexico than the United States, the one in Tampico that had a very high (bad air) reading made the entire region look worse than it is. There was another sensor in Tampico with good readings but there are too few of them to moderate the bad readings. I probably should have moderated the map a bit more and not spread the red color so far and wide there. Veracruz was also impacted by a negative reading from a town over a hundred miles inland from there.


Day 11 - Minimal

For the minimal theme, I revisited the paper cut map, mainly because I liked this version I had made for Day 9 and here was an excuse to use it. This one is presented against my blue nylon jacket, standing in for the water.


Day 12 - Map from 2125

We are instructed to make a speculative map showing 100 years into the future. I used predicted sea level rise data from NOAA, a US agency, so there is no Mexico data. These estimates are conservative and are not as alarming as they maybe could be. I did a little airbrushing of the colors representing inundated areas and added some Chinese text to list the Chinese States of America, Mexico, the Gulf and the Special Administrative Autonomous Region of Houston. Just having some fun speculating, nothing to take too seriously.

Next week - more!
