Same here, everything is x, y, z when I first start.

Thank you!

Visa requirements for US passport holders by country. There are 46 countries with no visa requirements. 152 countries with visa requirements.

Trying to get back into the #tidytuesday habit. Using visa data from the Henley Passport Index (2025-09-09) to see where I can go without a visa.

Area graph of speaking lines by main character for The Simpsons

#tidytuesday I am a bit late on this, but the show is really all about Homer. Speaking lines by character for seasons 21-26.

I learned how to ski a few years ago and like to keep track of where I have been. I am super excited to have found openskimap.org; so much map data is available! Now that I'm back from holiday break and have been looking for a new map project to start, I think some sort of ski map could be fun.

Fell a bit off the #AdventOfCode wagon, but trying to get back at it. I work almost exclusively with dataframes as inputs, this reminds me that there are other data structures. Completed “Print Queue” - Day 5 adventofcode.com/2024/day/… GitHub: github.com/mhegeman/…

Just completed “Ceres Search” Day 4 of Advent of Code 2024. Part 1 was a breeze, boosting my confidence, but Part 2 fixed that. As usual, I was overthinking it. #Python #AdventOfCode adventofcode.com/2024/day/… Github: github.com/mhegeman/…

So, today, I learned about regex, which is not something that I have used before. I just completed “Mull It Over” - Day 3 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/… #Python

I just completed “Red-Nosed Reports” - Day 2 - Advent of Code 2024 #AdventOfCode I will eventually share answers on Github, but does anyone have a favorite resource to help with Python when you are coming from R? Ihttps://adventofcode.com/2024/day/2

Because I am a glutton for punishment, I’ve decided to give #AdventOfCode a try to practice my Python skills. I’ve completed “Historian Hysteria” - Day 1 - adventofcode.com/2024/day/…

Map of Antarctica showing the locations of shelters across the continent.

The #30DayMapChallenge has wrapped up. I didn't complete every map, but I pushed my skills with mapping in #rstats and open-source #gis tools out of my comfort zone. My final map features shelters in Antarctica using a polar projection 😊 https://www.mel-likes-maps.com/2024/12/01/polar-mapping.html

Lambert Azimuthal Equal-Area projection, north western hemisphere.

Bad rendering of UTM Zone 14N map showing northwestern hemisphere.

Catching up on the #30DayMapChallenge, so I’ll cover AI only (Day 9) and Map Projections (Day 26) with one set of maps. I used Claude.ai to write an R script to show different map projections - no edits from me! The results are a mixed bag! #gis Full post: www.mel-likes-maps.com/2024/11/25/a...

I missed the polygon map from the #30DayMapChallenge, so I am circling back to find counties with campgrounds. Continuing to experiment with #duckdb and #rstats to query and present spatial data: https://mel-likes-maps.micro.blog/2024/11/24/spatial-queries-with.html

#30DayMapChallenge Day 13: A new tool. I finally took the leap and experimented with DuckDB to create and access spatial data from #rstats. #gis #duckdb mel-likes-maps.micro.blog/2024/11/1…

Map of Magellan's route around the globe.

Day 7: Vintage Style #30daymapchallenge I used Esri's Modern Antique Map as the basemap. I searched for a table of Magellan's ports but found nothing, so I asked ChatGPT for a .csv with ports, dates, lat, and lon. Even after some formatting tweaks, I got a result quicker than doing it by hand! #gis

Aerial imagery with an image classification overlay.

#30daymapchallenge I rarely have to use rasters at work, so I decided to try some image classification for Day 6: Raster. 🤨 I'll have to keep practicing.

Animated map of orca encounters in Puget Sound by year (2017-2024).

#30DayMapChallenge Day 4 - Hexagons. My attempts to map with #rstats continue. I used the orca encounter data from Day 1 and plotted it against the H3 index to see if the best locations for seeing orcas changed annually. #GIS

Static world map of travel routes.

Static world map of travel routes with routes color-coded by year.

#30DayMapChallenge - Lines. To keep it simpler today, I wanted to make a travel map highlighting some of my favorite trips with #rstats.
How it started vs How it's going... still needs a little work.

Graduated symbol election map of NC.

Finally, some graduated symbols. #GIS

Map of orca encounters in the Pacific Northwest by year.

I've been wanting to learn more about mapping with R for a while, and now I am finally getting around to it. #30DayMapChallenge #TidyTuesday I'll be adding to this project for the first few maps.
