It depends on the reader. If they use it to navigate somewhere, or to explain to someone the location of a thing/place in relation to something else in the image, then it's a map. If they just think it is pleasant to look at, then it's a photo.

I am also celebrating by finally organizing my #cyanotype misprints and having another one of my irregularly-scheduled "pay what you want" sales. Please consider giving a home to one of these less-than-perfect hand-printed pieces. Some have scorch marks!

Where curiosity leads: Crafting stories with Aaron Koelker The ArcGIS StoryMaps team sits down with Aaron Koelker to discuss his approach to creating delightful and informative stories.

Excited I could chat with some of the StoryMaps team about, well, stories and maps. You can read some of the conversation here: ow.ly/cL1n50WzKHG

Perhaps it can just be an amusing distraction from all the physical exhaustion, then

Thanks! It was actually harder than expected to find those kinds of things, and I ended up putting my own list together based on various articles, interviews, documentaries, etc. Hopefully they're actually meaningful to runners!

Currently obsessing over this 12 ft wide, 1921 strip #map of Palisades Interstate Park in NJ/NY. An amazingly detailed birds-eye view paired with a profile sketch of the park's cliffs, as seen from the Hudson River. collections.lib.uwm.edu/digital/coll...

A quick and dirty map I made of the federal lease cancellations announced by DOGE so far. Data from DOGE's website on 3/14/25.

Glacial Gardens Relicts, Refugia, and Preserving Biodiversity

A few months ago, I made this #StoryMap about glacial relicts and refugia, with a look inspired by botanical field journals. It was a fun side-project to reseach and create. storymaps.arcgis.com/stories/9b04...

That's so cool. Is it running with something like an Arduino or Rasberri Pi inside?

Thanks! Mostly by hand on an iPad, yes. I wrote about it a bit on my website: aaronkoelker.com/taughannock-...

I recall iterating over bands with arcpy/python once, but not sure about model builder. ArcGIS Pro has an Extract Bands tool that might work for that, though

This map covers the Guana, Tolomato, Matanzas estuary and watershed around the city of St Augustine, on the east coast of Florida. It is a tall, narrow image with the ocean in light blue to the right and white land to the left. Conservation areas are shown in light green, while wetlands are a faded olive color. In the top left corner is a abstract water diagram showing the major rivers within the watershed and the tributaries that flow into them. A logo for the Matanzas Riverkeeper and a mission statement sits in the bottom left corner. The logo is the stylized outline of a great blue heron in blue and orange colors.

Recently updated this map for a watershed non-profit group to be vertical instead of horizontal. The original use-case was for tabling events, so we'd made it wide to get more of the map closer to the reader and save them from having to lean forward. The new layout is for signboards at boat ramps.

This was made to support a project on glacial refugia, explaining how the landscape and climate have shifted over time as ice sheets advanced and retreated

Thanks! It can be pretty stark in places. Places like Bloomington it even shows up clear on the aerial imagery, neat to see

Was this in the NACIS map gallery last year? If so I remember staring at it for quite some time. Awesome work!

This animation I made for a recent project shows the changes in ice extent over North America since the last glacial maximum (roughly 18k years). Each frame was hand drawn using Procreate.

Interesting, I could see that especially for movies that are so bad they're funny
