Hi everyone! It’s going to be a short newsletter week, but I wanted to make sure to send it out since I missed last week - but there’s still some good stuff in here to help you better understand coordinate systems (I can hear you shuddering already), troubleshoot ArcGIS, and some cool technology. Enjoy!

Prepare Yourself for the Coming New Datums with a Refresher from NEURISA - YouTube
Here’s a video with information on the new datums coming in 2022 - there are already epochal updates to existing datums that help deal with little things like continental drift, but this sounds like something bigger (akin to the NAD27 to NAD83 shift). Worth watching at some point if you work with GIS!

EPSG.io: Coordinate Systems Worldwide
A nice database of spatial references for the whole world - not much more to it than that! It’s sort of like spatial-reference.org, but different :).

Troubleshooting Error 999999 in ArcMap and ArcGIS | CWS Help Website
Set up your tool in ArcGIS, hit OK to run, and then… Error 999999 Unknown Error. The bane of the GIS analyst. In response to a number of questions I’ve gotten from students recently about this error, I wrote up a handy set of troubleshooting steps to take to resolve this error - already solved one persons problem! I’ll probably even reference this myself next time I get the error.

Skybox Imaging Captures World's First High-Resolution, HD Video of Earth from Space (1080p HD) - YouTube
This video isn’t new, but should still be pretty mindblowing to those of you who haven’t seen it yet - stabilized HD video from space (from a satellite orbiting at 17,000 miles per hour - 24,000 km/h) that can even do vehicle motion tracking. This kind of data is going to explode for monitoring economic activity, environmental health, and more, once there’s a constellation of satellites with this capability.

Brand New Subway
This is a fun, and well-made, application that lets you redesign the New York City subway system to your heart’s content, and which tells you what the ridership and fare cost would be for rides on that system. You can start from scratch or use the existing or future system and then make tweaks to design the ultimate transit system for the city. I don’t live there, but this is the kind of application I’ve dreamed of making - design your own subway? COOL! If you want an actual video game that’s similar, check out Mini Metro (a Google search will find it) for some more fun.
