Warm up this morning was actually hard. Had to walk half of it. But intervals went pretty well.

Day 16 - Cell
Nearest Hill in Rhode Island

The Ocean State is pretty flat, at least to someone who has lived in Appalachia for most of his life. The highest point is 244 ft. I sampled the elevation from a DEM & I mapped the nearest "hill" for anyone looking for a potential view.

✈️ Flying into NZ for #FOSS4G @foss4g.org - couldn't help but nerd out on all the beautiful tidal flats that surround Auckland.

Here's a quick #DEAIntertidal tidal flat elevation map of Auckland’s Manukau Harbour, generated using #opensource code + satellite data loaded via #OpenDataCube and #STAC!

What if all of Greenland's ice melted?

For today I played around with Greenland’s terrain elevation data beneath the ice sheet.

#5KADay 521 #running Monday was 10.1k in ~ 1:07:11, 73F, with a long water break at ~ 51 mins. Goals were, continuous 10k & 70 mins running but too darn hot & burning arm. The body glide doesn’t stay put so new burn abrasion under arm. Knees stiff after break but warmed up again. #Runchat #Runsky
Selfie of me after running ~ 1:07:11 with a break about halfway in because I was so hot and thirsty. Sweated out of my heather colored run top, also wearing purple hat, rx sunglasses. Background is a shady area of the more northern part of the path, which isn’t kept as nice but doesn’t have red light intersections, but car/ped safety isn’t better, more cars stop at the uncontrolled intersections in Albany and Berkeley/Oakland than El Cerrito GPS map of run. Went South in Albany/Berkeley/Oakland first, then went north to El Cerrito. Cooldown fitness walk back South which is off map Applefitness overview of 10k run with 41 meters elevation gain, 152 bpm average heart rate, 6’39” avg pace, 173 watts avg power. Screenshot of weather conditions for run. 73F, still air during run but noticed a breeze picking up on walk home, 3 UV index, clear piercing sunny skies for first ~ 9 kms.

Hihi, thanks for the artshare!

I'm Vihala, and I like to think of myself as mostly a TTRPG artist! But if I'm being so for real I draw whatever bullshit crops in my head, which is usually my OCs
A massive spider crab facing off against a magically augmented tornado in the background, as part of a boss splash for a TTRPG campaign. The piece is half painterly, half overlaid with art deco-esque lines. On top of the crab are the silhouettes of four humanoids. A TTRPG combat map for a church in Holo, my worldbuilt setting. It features pews with chromatic fires lit up on either side, a point at the front, and a higher and lower elevation. The entire map is rendered in a painter-esque style. A reference sheet for Darius, my TTRPG OC. He looks very stereotypically "demon", but is actually more of a fleshy mech suit for a nudibranch core that is his mouth. His humanoid legs are a fusion between a human's legs and a horse's, including the feet being made of solid keratin and being inflexible. He has wide wings and wears cozy pants and a blanket around his head. His night shirt is a satin night shirt fashioned to look like a toga of a sort. A Warriors cat (Alluringwhisper, glutenfrog (Twitter) 's OC) chilling in the snow. It's holding a fern in its mouth and looking up at the camera, which is situated right above it.

Lighthouse Marathon ✅

- 14 miles on brutal coast paths,
- 8 miles on road / trail,
- 4 ish miles on dunes.

Over 1,000m of elevation gain.

Slipped down a bank on mile 5. Stacked it coming into St Ives on mile 13.

Perfect weather and fantastic scenery
A strava map showing my route on the Lighthouse Marathon. I got lots of personal records on my third run on this route. A view of the coast path heading to a rocky area. The sea is on the left. In front of me is another runner. The sunsetting over the beach and sea on the last part of the Lighthouse Marathon.

#30DayMapChallenge 🗺️ Day 5️⃣: Earth

Here’s a minimal isometric relief map of Santorini. I haven’t been to #Greece 🇬🇷 but I definitely want to see Athens, and either Santorini or Mykonos. Maybe I hope that by creating this map I can manifest that trip? 😁

Digital elevation model data is from NASADEM.
Map of the island group of Santorini shown in an oblique isometric view such that the sea level is a very light tan color with the islands in an aqua color ranging from nearly transparent at sea level to very dark cyan at the highest point. The map is titled with a large text “SANTORINI” with the Greek “ΣΑΝΤΟΡΊΝΗ” above it in a smaller font size and the coordinates 36° 24′ 13″ N ▪ 25° 23′ 45″ E below in an even smaller font size.

#30daymapchallenge | Day 6 Dimensions | Unrealized Heights

Still tinkering with this one, but here’s unbuilt volume for large buildings within 1 mile of the Capitol, where the Capitol View Preservation Ordinance restricts buildings from exceeding the elevation of the base of the Capitol’s columns.
3D map visualization showing downtown Madison, Wisconsin, with transparent red blocks representing unrealized building volume below the Capitol View Preservation Ordinance height limit within one mile of the State Capitol. Existing buildings and trees are shown in beige tones, highlighting areas with potential for taller development constrained by the ordinance. The title reads “Unrealized Heights,” with details about the dataset and design credits at the bottom.
