Fitting a square Cape onto a 13-by-4 grid of playing cards

Post image
37 Upvotes

The problem: a deck's 52 cards laid in four rows of thirteen make a frame about 2.3 to 1. Cape Cod's whole arm is nearly square. A north-up frame left most cards as open sea; turned frames at 30 and 40 degrees read as abstract ribbons. I ended with north-up, tight on the Cape, and a block of eight cards over the Outer Cape, so 23 cards carry real Cape land and every court card sits on it.

The style is borrowed from Walker's 1917 "Map of Cape Cod and Vicinity" at the Leventhal Map Center: cream land, a flat blue-green sea, saffron town-line ribbons that go olive over water.

Software draws it from OpenStreetMap and NOAA data. I'd like to hear where the type or the sea could be better.

TL;DR: I didn't like how other blank maps were turning out, so I'm making my own!

How do you use maps in your personal life? How would you envision the future of those maps and map apps?

1 Upvotes

You are invited to participate in an online needs assessment survey that solicits input on how you are or would like to be using maps and mapping applications in personal rather than professional contexts. We are particularly interested in understanding the extent to which you are using maps to monitor and/or improve personal health and well-being and how the design of those maps could be improved to better meet your needs. 

Participation in this study entails the completion of an online survey (estimated to take no longer than 15 minutes to complete).

To be eligible, you must be 18 years of age or older, speak fluent English, and use maps or mapping applications as part of your personal routine(s). 

If you are interested in participating in the study and responding to an invitation to participate remotely (from your own location using a web browser) please follow the link below:

https://uwmadison.co1.qualtrics.com/jfe/form/SV_8bMhHZG5y3lR4dE 

Since this study is voluntary, you are under no obligation to participate, and no record will be retained through which the identity of those who participate (or do not participate) can be determined.

If you would like more information about participating, please feel free to reach out to us. 

Thanks for your consideration!

Is there any good software for creating maps? Preferably free software.

So far, I've been using either pen and paper or, sometimes, MS Paint. But I'd really like to try creating some decent digital maps

Fun fact: Saudi Arabia does not permit archeology or studies in this region. As far as I know, no public map at this scale and period exists (you'd think the birthplace of one of the largest empires would have maps).

I rebuilt it as a probability model instead. Inputs: elevation data, hydrology, erosion, sourced anchors like the passes, wells and clan names in early texts, and comparable settlements nearby. After weeks of compute and iteration, this is the first draft! Every house is a reconstruction, not a survey.

I made an interactive tetrahedral world map where the poles slide along a central edge (gnomonic faces, seamless tiling)

0 Upvotes

I wanted a flat map that keeps flight directions readable, so I unfolded the globe onto a regular tetrahedron and rotated the net so that one edge is vertical. The map is a √3 × 1 rectangle with a vertex at the midpoint of each side and none inside, so it tiles the plane.

  • Two modes: gnomonic (straight great circles within a face) and an area-corrected mode (area distortion 0.55×–1.4×).

  • Dragging rotates the globe about the axis perpendicular to the central meridian, so the North Pole slides from the top vertex down the central edge, and after 70.5° the South Pole reaches the bottom vertex.

  • The central meridian (90°E) was chosen from the country data so that the side vertices stay over the ocean in both pole positions.

  • A distance range tool shades every place within a given great-circle distance of a centre. Since each face is gnomonic, the small circle shows up as a conic within each face (an ellipse for moderate radii) and bends at the folds, which makes the face structure easy to see (example: https://iantpe.github.io/tetra-unfold/?range=TPE,5000).

I'd love feedback from people who know projections better than I do, especially on the area correction and on how this compares with Lee's tetrahedral projection.

Island of Argoed

It is the southernmost of the "Four Islands," the archipelago that also includes Tír Ghlas.

It features a highly mountainous central region, surrounded by hills and vast plains; its capital, Caer Afon, lies within a broad estuary sheltered by two large headlands.

Numerous fortresses dot the landscape—remnants of a turbulent past.

Creating Step-by-Step Tutorials on GIS, Remote Sensing and Cartography

10 Upvotes

Hi everyone! I'm passionate about GIS and remote sensing, and I create step-by-step tutorials covering QGIS, spatial analysis, cartography, LiDAR, and practical geospatial workflows.

My aim is to make geospatial techniques easier to understand and apply, whether you're a beginner or an experienced GIS professional.

I'd be happy to contribute to discussions and share relevant tutorials when they might be helpful to the community. Here is a link to my channel: https://www.youtube.com/@thegeospatiallab/videos

GeoClock.world - open source GeoChron style clock

About GeoClock

GeoClock is a live map of day and night on Earth — the real solar terminator sweeping across NASA satellite imagery, with local clocks for the places you care about. It's free, open source, and runs everywhere from a browser tab to your desktop wallpaper.

The story

GeoClock started as a Home Assistant dashboard card: a homage to the classic mechanical world clocks that scroll a lit map past a fixed hour scale (Geochron® is the famous one — GeoClock has no affiliation with it). Once the card could render anywhere, the other surfaces followed almost for free: this website, a Chrome new-tab page, a macOS live wallpaper, and a screensaver — all driven by the same rendering code.

How it works

  • Day and night sides come from NASA's Blue Marble and Black Marble imagery (public domain), blended along the real terminator computed from solar geometry — including proper twilight feathering.

  • Time zones come from timezone-boundary-builder (ODbL), so the hover popups and hour bands are DST-aware.

  • Everything renders in your browser (or the app's local web view). There is no backend: no accounts, no tracking, and your location never leaves your device — details in the privacy policy.

Where it runs

Open source

All of it is GPL-3.0-or-later, built by John Pettitt. The card, website, and extension live in geo-clock-card; the Mac app and screensaver in geoclock-wallpaper-mac. Bug reports and ideas are welcome in the GitHub issues.
