Me on Saturday: I’m never doing an ultramarathon again

Me now: *scheming with the topomaps*

When your EEG (brainwaves) data are literally smiling back at you! 😀 🧠

Uh oh I spent the evening looking at topomaps and scheming again

👀

As a photographer here in the South Ngai Tahu's cultural map is, alongside TopoMaps, the most valuable tool I use.

I am at pains to use the correct name for everything now.

I mean I didn't know it was Lake Takapo, but I love that.

Another Houdini experiment, where I was converting heightfields into topomaps and then doing strange things with them - I know the compression is going to kill this - this was rendered in Redshift #houdini #3dart

It could be the end of Eglinton Ave with the wood bridge (W) that goes over the west branch in this 1909 topographical map.

Huh. That’s nothing like the SAR training I did in Virginia — we always had our phones… I mean we trained in a lot of places with no coverage, but we often talked about useful tools like offline topomaps for phones.

Can’t count that the phone will work for wilderness SAR so don’t be reliant, though

Yup. That's probably it. I'm trying to get my new student up to speed on our American Viticultural Areas Digitizing Project that requires topomaps, so it makes sense that it went down.

Biggest change was plotting topomaps when channels are spatially overlapping (3 channels per sensor). Now MNE just plots the most radial channel in each OPM sensor.

Most of the other stuff came from handling mag-only arrays in MNE pipeline, or ignoring calibration files for SSS.

🗺️ Revisiting a post today about bringing 100k U.S. Geological Survey (USGS) Historical Topo maps into gee-community-catalog.org.🌎 I get to post this while visiting USGS HQ, the home of where many of these maps.

I never knew that Quebec/New Foundland and Labrador were so beautiful. I want to go to Lac Agramonte http://www.canmaps.com/topomaps/nts50/toporama/orthoimages/023e12.jpg (large)

Scotland Ordance Survey has this lush web service,

Topomaps 1:63K 1857 - 1891 mapseries-tilesets.s3.amazonaws.com/os/one-inch-...

Deep dive into EEG data science! 🔬 We use MNE-Python to clean, filter (1-40Hz), and epoch brain signals, then stitch it all into a dynamic topomap animation. Major troubleshooting required for undocumented event files! Full process: youtu.be/tO3f2gNVSMg #EEG #BCI #Python

USGS has launched a new line of recreational topo maps—just in time for fall hikes in The Natural State. 🍁
Packed with trails, campsites, and more, explore responsibly and confidently.

Logically speaking, what you say makes sense. But the details of topomaps and contour lines are quite unstable, so I would personally be inclined to dismiss that subtle difference as noise. What would you say, @olaf.dimigen.de?
