Once I crack this for my context case, I get to be very happy. It is old code Infound that I have been using for YEARS. It has worked this whole time until I tries pipes and content that was perfectly vertical. I had a slick way (then) of getting my number fast, but never considered the how I got it, and it was strictly bad math!! I had a div by zero issue since the X1Y1 and X2Y2 were equal, and I was using maths for a 2D situation.
What I literally need is X here, because it is the number I need to find distance from primary pipe end to place a branch node.
This has real world implications wherein we save a LOT of money at the shop by this process correcting broken branch nodes-- at the fabrication stage, this point is used to automate cuts for the taps on the pipe, and cut them out by plasma torch.

30 DAY MAP CHALLENGE 2024 | DAY 1 - POINTS

The Philippine archipelago mapped using 10^n points with each point being 1000 x 2^(6-n) meters in diameter.

DATA
> GADM country-level data (adm0)

PROCESS
> Use the "Random points inside polygons" algorithm in QGIS to generate layers with 10^n points
> Style accordingly
> Add the 6 layers into a single Print Layout

Not sure if this qualifies as #points or raster for #30DayMapChallenge

The City of Wolfsburg is home to German automobile manufacturer #Volkswagen (VW). Population counts from the 2022 census are mapped as proportional symbols, each representing 1 hectare. Point like symbols clearly depict residential quarters south of the train station against the industrial area above.

#30DayMapChallenge #points

I looked at the ratio of male/female commuters. Seems like in most urban centers the commuting flows are dominated by women.

"Which direction shall we choose?" asked Timon, looking up from the map. "North? East? South? West? Our ship is shipshape! We're provisioned and ready to go."

Fuyumi traced the #points on the compass rose. "South by southwest," she announced. "Through the Sea of Serenity to the Sea of Vapors."

Timon grinned. "Aye aye captain." he turned to the waiting crew. "You heard the captain! hoist sails!"
