Gerrymandering the USA Black Belt

October 1, 2016

Found myself in a discussion yesterday about homogeneous anthropological districts, in particular the USA Black Belt.

Just thought I’d take a look at the present political representation.

Enceladus — for counting craters

May 11, 2016

This map corrects map-boundary imperfections in the earlier Enceladus maps.

Note the smoother curve at the both pole (left and right tips of the map), and the tangent-to-the-vertical cusp.

Enceladus centered on the north pole

Enceladus “B” large file

March 16, 2016

Here’s the map in near-maximum resolution. (Click on map for full-size version)

(You might have to open it in a photo-editing software such as Photoshop. I have trouble opening this in Mac Preview.)

(Not sure if this will work; it’s the largest file I’ve yet posted.)

(Yeah. Doesn’t want to open on screen. Try right-clicking on the map and select “download linked file.”)

Suggestions welcome for how to fix this posting glitch. EDIT: the download problem appears to be native to my home computer. Enjoy the map!

Enceladus gets another custom projection

January 13, 2016

Enceladus D_Titled_postI had to make up the projection. Long story. Summary is that the cut (the edge of the map) is 270˚ (three-fourths of a circle).

The purpose was to put the tiger stripes, the south polar district, into global context. Other compact maps were either unable to make the polar region large enough, relative to the nether regions, or the map periphery went squirrelly.

The cut can turn on 45˚ increments, which has the effect of rotating the stripes around the pole; the lobes refocus from leading and trailing hemispheres (the posted map) to anti- and sub-Saturnian hemispheres.

A really large version is in the works. Maybe by March, knock on wood.

Here’s what the grid looks like:

with a little Photoshopping, you could make your own! Hmm . . . would this projection be of any use on another planet or moon? Pseudo-Eisenlohr Grid

For instance, here’s the projection applied to Earth (not that you need to know where is San Luis, Argentina!). Not so useful because of the longer interruption.

The mosaic is based on the July release, so I expect NASA will have something better for us soon.

Spaces & Illusions

October 9, 2015

My design for an children’s participatory exhibit titled Spaces & Illusions, which was  installed from 1976–1980, give or take a few months, at Atlanta’s High Museum of Art.

Its appearance here in a blog about a novel way to make world maps may appear incongruous until I offer that the process of designing and installing the exhibit presaged all the constant-scale natural boundary maps you find here.

Presaged in a cluelessly groping way, I admit, but some things take time to resolve themselves.

Enceladus Foldable Globe

January 18, 2015

Hey, if you’re visiting from papermodelers, leave a note in the comments. I’m  curious to hear what uses you put this model to! Thanks, Chuck


Oh, by the way . . .

Under the Pages menu (on the right), a new cut’n’fold map of the asteroid Itokawa sneaks onto the blog.

Also (March edit), the beginnings of a cartographic exploration of Enceladus geology.

And (April edits) a poster recently presented at the Association of American Geographers annual meeting, as well as the start of a meteorological animation.

Further (Feb 2011 edit) a Ganymede foldable geology globe.

Watersheds “N” with currents

At a loss for words at the moment; must confess I’ve been absorbed in these patterns:
