First day of #30DayMapChallenge complete! I used #rstats for this, including several new (to me) packages: #rnaturalearth #ggrepel and sf (for #SimpleFeatures which is new to me...this is all new given this is the first map I've made in R 🗺️). Lots more to learn...

A map of "Cities Visited in the Past Year" which is from November 2023 through October 2024. Includes Amsterdam, Portland Burlington, and several others

Today the third draft of the 𝗦𝗽𝗮𝘁𝗶𝗮𝗹 𝗟𝗶𝗻𝗸𝗲𝗱 𝗗𝗮𝘁𝗮 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀 book made it on-line.

This new version is primarily an expansion to conform with #GeoSPARQL 1.1. Novel content also on #SimpleFeatures and #MetaData, plus the odd correction and bug fix.

Your path to #FAIR with #OGC and #W3C standards.

Why #dependencyhell every time you try to use #rspatial packages like #terra #simplefeatures #gdal - how do people deal with this issue? #rstats

Work in progress.

If you ever wonder why you polygon layers so frequently contain invalid geometries: even regular national borders violate the #SimpleFeatures topology rules 🤦‍♀️

Day 31: Break a previous image.

For some reason, I did break a lot during this #genuary:

For this prompt I break a previous image by _unbreaking it_.

Coded in #Rstats using #ggplot2 , #SimpleFeatures, and #rayverse

To the left is the original smashed polygons, to the right the "broken" unsmashed ones.

Day 27: Hilma af Klint

A practitioner of automatic painting, af Klint's abstract work predates that of Kandinsky, Malevtich, and Mondrian.

https://en.wikipedia.org/wiki/Surrealist_automatism#Automatic_drawing_and_painting

For this piece I drew inspiration from The Swan series. So simple and yet so full of depth. This seems to be a popular reference for today's prompt!

@AaronReuland @jacquietran @meghansharris @davepagurek

Coded in #Rstats using #SimpleFeatures and #ggplot2. See my repo:

https://github.com/paezha/genuary2023/tree/master/2022-01-27_Hilma-Af-Klint

A piece of generative art created using the R statistical language is a homage to Hilma af Klint's The Swan. The image is a background in solid color and three concentric circles split down the middle and painted with different colors on each side. At the center there is a triangle also split down the middle. af Klint was a practitioner of Teosophy and her paintings, while abstract, where full of symbolism.

Day 25: Yayoi Kusama

This piece draws inspiration from the Kusama's Infinity Mirrors. I got to use some of my favorite R packages: #ggplot, #SimpleFeatures, and #rayrender. Three outputs are shown here, with glossy, diffuse, and metallic spheres.

Coded in #Rstats. The code is available in my #genuary2023 repo:

A field of packed glossy spheres, in different sizes and predominantly in yellows and blues. There is a light source shining from the bottom creating subtle shadows on one side of the spheres.

A field of packed mate spheres, in different sizes and pastel colors, ranging from red to green. There is a light source shining from the bottom creating subtle shadows on one side of the spheres.

A field of packed metallic spheres on a black background. The spheres vary in size but they are all shades of blue. There are reflections of reflections on their surfaces.

This is a homage to @terence whose shattered tessellations I've long admired:

I haven't figured out how he creates the cracks. Here, I borrowed an L-system from A. Sanchez Chinchon to smash a Voronoi tessellation.

@tylermorganwall @jacquietran @meghansharris

A voronoi tesselation was smashed to create a cracked effect. This resembles a polar landscape with ice shards and snow.

Signed distance functions are buffers with values that are proportional to the distance from the primitive geometry. This image was coded in #Rstats using #ggplot2 and #SimpleFeatures.

The code is available in my #Genuary2023 repository:

@jacquietran @meghansharris

Isocurves surrounding three primitive geometries, a triangle, a square, and a diamond. The colors change with distance from the boundary of the primitive geometry.

Day 7: Sample a color palette from a favorite movie.

Like @jacquietran, I use package {ghibli} with palettes inspired by Miyazaki movies. Jacquie chose Ponyo, I chose Laputa. I first saw this movie years ago on TV when I was a student in Japan.

The truchet tiles are almost like alien glyphs, something you might see in the floating castle.

Coded in #Rstats using #SimpleFeatures and #ggplot2. Code is in my repository:

https://github.com/paezha/genuary2023/tree/master/2022-01-07_Sample-a-color-palette

@meghansharris

Truchet tile creates the impression of alien glyphs or a colorful labyrinth. Colors are sampled from Miyazaki's Laputa: Castle in the Sky.

#Genuary3 #genuary #Rtistry

The prompt for Day 3 is Glitch Art.

For this prompt I present glitched geometries, created by overlying two sets of voronoi polygons, one of which is a glitched version of the original. Coded in #Rstats using #ggplot2 and #SimpleFeatures

The code for this piece is in my #Genuary2023 repository:

https://github.com/paezha/genuary2023/tree/master/2022-01-03_Glitch-Art

@jacquietran @meghansharris

Abstract piece of glitch art created by overlying two sets of voronoi polygons. A tantalizing semi-regular pattern of lines, polygons, and colors gives plenty of room for interpretation.

@pokateo

GIS-adjacent: I created a new workshop package to teach exploratory data analysis (EDA) in #Rstats. The package includes #SimpleFeatures data objects for mapping!

Good morning! Today's generative skyline is a rainy crepuscular cityscape. Despite the rain, there is something festive about the light in all those windows.
