#gischat Cartographic Representations were an ArcMap thing only, is that right? What took over from that in Pro? What does Esri call the functions that do on-the-fly symbology changes like line offsets and layered symbol styles?

The First Amendment defined the right to free speech and a free press. But a free press doesn't just happen. It's something we must protect. Your support is essential to our ability to provide journalism that upholds your right to know. Donate now: n.pr/4hgyjzz
Statement on White House bans from Thomas Evans, NPR’s Editor in Chief: Barring journalists from the White House because the president dislikes their reporting is a blatant violation of the First Amendment, and NPR condemns it without qualification.The American public has a right to know what its government is doing in its name — not only the coverage a president finds flattering, but the full and accurate account of the use of power and public resources.That right belongs to the public, and it is not the president's to revoke. The press, and specifically public media, exists to conduct that accounting to every American, in every community, in service to the public interest.NPR and our Member stations will continue to uphold these First Amendment rights, and to stand with any news organization targeted for its reporting.

Why Japan wants the new world map changed
Japan was among the 164 UN members that supported the new world map, until it realised the disputed Kuril islands were in the same colour as Russia.

TLDR... John Snow wasn’t the cartographer, he didn’t invent GIS, the map didn’t lead to the discovery of the outbreak source. This is once of geography's oldest and least accurate mythologies. What's too bad is the real story is still very interesting and informative!

Every time he does this he erodes the value intrinsic in the American identity. He makes himself a petty weak fool, he erases history, and diminishes the identity of a nation to nothing more than a crude branding mark that will inevitably be undone when he's dead and gone.

All cops should have to spend their first two years on the job without a firearm so they are forced to rely on other tactics besides pull out gun and yell. They can partner with an officer who has already had two years of firearms restriction and is allowed to carry a firearm.

Great example of why NOT to trust the AI summaries. Asking a question about outboard motor placement the AI responded with an absolute answer about the height (2" below bottom) but the post that answer is based on the author only stated how their motor is currently set up, not how it should be.

Want to work with the GIS data from this lava flow map of Kilauea? The USGS data release (if you can find it) lists 100 separate items. Want to download those individual footprints? You will have to individually grab each of the shapefile component files, for every lava polygon layer. WTF?

The problem w Trump is because he's a narcissistic prick who doesn't care about US citizens, he's likely not suffering any of the normal stress induced health issues you'd expect the worlds most powerful person to have. He's literally too selfish and stupid to suffer the ill effects of his own job.
