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! docs.google.com/document/d/1...

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

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.
A blue and grey map of the United States and territories showing the number and location of federal lease cancellations, using proportional circles and number labels.

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...

A particularly tricky round of Cartographer's Tetris
A map of Long Island NY with green labels and markers over orange land. The labels are dense and often curved to fit.

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 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.

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.

Happy Halloween. Here's a map I did several years ago of cemeteries and graveyards within Great Smoky Mountain National Park. Fun fact: the difference between a cemetery and a graveyard is that the latter is typically associated with a church.

This is a #map (?) I drew of Taughannock Gorge in upstate NY. I designed it specifically with a #risograph machine in mind, and printed it out at a community print space here in town. Excited to try out some other ideas there.

Since videos don't work here yet: Here's a link to another 10ft receipt map I made of the Boston Marathon. It's contained in an enduro route sheet holder so that, theoretically, someone could awkwardly reference this on their wrist while as race. aaronkoelker.com/boston-marat...

Experimenting with a hand-drawn approach
A post-card sized map of the Great Lakes. Water is in blue with green outlines around the shore. Urban areas are shown in orange, and cities are shown with black circles and labels. The style mimics a rough risograph print, with some printing misalignment and imperfections.

I recently moved to Ithaca, NY—so I made this #map of waterfalls to help get familiar with the area. I look forward to finding a typo immediately after posting.
A map of about 50 waterfalls around Ithaca New York. The colors are primarily blue and green. The background features hand drawn rivers, lakes, and streams, and the terrain has a painterly style.Closeup of a map of about 50 waterfalls around Ithaca New York.

Here's a technique I've been using to create dynamic highlights on my data in ArcGIS Online—handy for a bit of extra visual flair or filtering out data when you don't have the right attributes. I've been using it with shifting hurricane forecast cones. youtu.be/M7e2N3c_WvI?...

Here's another ribbon map of a river; this time designed specifically for a receipt printer. Perhaps the most unnecessary thing I've ever made.

For the multiple people that suggested using a receipt printer. Not perfect, but readable! Will be a fun challenge designing a new map that works within the limitations.
Part of a river map being printed from the top of an Epson receipt printer: black plastic cube with roughly 7 inch sides. The visible part of the map says Pinhook Swamp on the right while the river can be seen as a thick black line to its left.

More reposts, this 12ft long ribbon map of the Suwannee River with a 3D printed wind-up container. I'm now looking into buying a receipt printer... for reasons.
A black 3D printed capsule with the end of a ribbon map extending out from it on to a table, the end of which is against a ruler showing it is 2.5 inches wide. Rolled up draft copies of the ribbon map are upright on the table as well, adjacent to the container.A close up of the ribbon map showing the overview area of the river across Florida dn Georgia, as well as the legend and a list of distances between towns on the river. The colors are mostly bright greens and blues.Two copies of the ribbon map pinned to a board at the NACIS 2023 map gallery. One copy is the 12ft long version and is pinned up into long folds with a paper clamp. The other copy is a 12 inch wide by 36 inch tall version with the map arranged in 4 side-by-side sections.

I'm going to repost some things from that old bird app for some semblance of continuity here, starting with this experimental Blender map of the St Kilda Archipelago I made a few months back.
An isometric view of the St Kilda Archipelago, with cyan water and green, cell-shaded land. Labels in white and pale lime color, some floating above and below the islands while other curved labels lay at an isometric angle on the water's surface.
