#ArbolateSum is my favourite spatial hydrography parameter...

So I asked AI (on my personal PC) to make me a t-shirt in the style of #SpinalTap, the prompting was fun...

My 'favourite' technical phrase specific to hydrography - Arbolate Sum - I thought deserved an #AISlop band t-shirt in the style of 'Spinal Tap'...

“... Several things stand out:
1) the massive flow of the mighty Mississippi and Columbia River systems
2) the paucity of major rivers in the western US, especially the southwestern US, where the only major rivers are the seriously over-tapped Colorado and Rio Grande Rivers
3) the local importance of the Sacramento-San Joaquin Rivers in California, which serve the state’s cities and agricultural regions…”

I don't get to be here that often (and that is OK, #ILikeMyJob) - but it is nice to be back working directly with some individual spatial datasets - be it in #QGIS, #ArcGISPro, #PostgreSQL / #PostGIS or wherever...

I really enjoyed seeing all of the Day 1 toots and data viz! For Day 2, I’m getting out of my comfort zone to explore hydrological data. The map shows streams and reaches from the USGS National Hydrography Dataset (Hydrological Unit 8) in the upper Potomac River Watershed.

Blow-Me-Down Brook, NH – An NHD Flowline Picked ‘Randomly’

I am working on some hydroaddressing / network traversing technical approaches for 3DHP – and needed an example of a multisegment flowline in NHD-sourced dataset, and so ‘randomly’ got this one - Blow-Me-Down, NH, from WBD HUC4-0108.
Although we map so many flowlines (~20 million in the USA for NHD-sourced spatial data, estimated 10x that for the EDH data still to be determined across the USA), I like trying to understand what a flowline or waterbody ‘is’ to the people on the ground as much as I can...

Saturday afternoon, we reached our NHD fundraising goal! 🌎 ✈️

THANK YOU SO MUCH!

We're ending the GoFundMe tonight (Sunday night). Any additional funds we receive today will be given to the girls' teachers to help defray their travel costs.

https://www.gofundme.com/f/help-our-girls-get-to-washington-dc

On behalf of all the families, we are so grateful for the support we've received from all over.

We have raised ~ $3,800 so far toward sending my daughter and her classmates to National History Day. 🌎 ✈️

THANK YOU!

We have reduced the goal on our GoFundMe to accurately reflect the families' updated cost estimates. We still have a ways to go, and appreciate any signal boosting you can do!

But — we heard today our school district won't pay for teachers to attend. 👩‍🏫

Something personal: My daughter and five of her classmates are raising money to travel to Washington D.C. to compete in the National History Day competition. 🏛️

https://www.gofundme.com/f/help-our-girls-get-to-washington-dc

The six girls are students in the Ferguson-Florissant school district. They took top honors for individual and group performances at the Missouri state competition, securing spots in the nationals. 🏆
