why would anyone sell this machine

thanks!

Today is a great day for the ocean!

Not only is the new Attenborough Ocean film out today, but I had a sneak peak at the new Great Map at the National Maritime Museum in Greenwich, and it's FABULOUS. A giant Spilhaus projection with beautifully detailed topography. Opens to the public June 7th. 🌊

WOW! I'd love to see that some day.

Glorious!

Please don't watch this video about making the Handsome Squidward version of ArcGIS Online maps.

Here's a breakout of coordinate precision by the actual cartographic scale they purport: Decimal Places Actual Distance Say What? 6 10 centimeters Your footprint, if you were standing on the toes of one foot. 7 1.0 centimeter A watermelon seed. 8 1.0 millimeter The width of paperclip wire. 9 0.1 millimeter The width of a strand of hair. 10 10 microns A speck of pollen. 11 1.0 micron A piece of cigarette smoke. 12 0.1 micron You're doing virus-level mapping at this point. 13 10 nanometers Does it matter how big this is? 14 1.0 nanometer Your fingernail grows about this far in one second. 15 0.1 nanometer An atom. An atom! What are you mapping?

I return to @johnnelsonmaps.bsky.social 's Silly Geographic Precision table whenever I see the coordinates in a file I'm trying to make smaller. Latest file was mapping atoms. uxblog.idvsolutions.com/2013/11/sill...

Ah, an oldie but a goodie! And, ah-hem, 6 years before XKCD did the same thing.

Exquisite!

I'll be at in London May 12 for a 1/2 day cartography workshop hosted by @esriuk.bsky.social. If you'd like to spend a half-day of your allotted time on this earth nerding out on map making with me, here are some details. store.esriuk.com/product/arcg...

things I like: the Yuka app

Glorious

things i like: the random 3 or 4 days in a Michigan April when it hits 70 degrees and everyone goes a little bit manic.

i like to kick things off with an existential crisis

I just shared a new video about making that faded inner-ribbon pattern thing in ArcGIS Online and stuff. it's over on the you toobs.

things i like: the internet circa 2010/11

The #EsriUC agenda is out...and there's BIG news for fans of our Map Wizardry workshop. Not only have we got a third offering for the Friday crowd but we got into the plenary hall on Thursday. Thanks to everyone who ever asked for this!!! No pressure at all 🤪

map with red border and faded hatched fill around the interior perimeter

whoa, just had a crazy idea for getting faded inner hatched ribbons for polygons in ArcGIS Online and it totally worked! now, to try to get back to my original objectives today.

Glorious.

things i dislike: jeans in colors other than blue.

¯\_(ツ)_/¯

things i like: my authenticator app gives me a two-digit number to access my account. i seem to have an impromptu anecdote for every number, which helps me remember it in the three seconds between seeing it and keying it in.

things i like: the sound of Bob Ross' palette knife mixing paint.

things i like: ironically, the amount of my brain's memory locked up with 80s jingles and sitcom intro songs.

things i like: finding a good deal (like every other Midwesterner). www.esri.com/arcgis-blog/...
