Ich bin leider eine Nachteule und werde erst (spät)abends produktiv. Jetzt habe ich Ideen und dazugehörige Tabs im Browser offen, was ich für @GeoDatenGuerilla schreiben kann bzw. was für Projekte ich angehen / weiterführen kann. Leider habe ich morgen Termine, auf die ich mich noch etwas vorbereiten muss und weswegen ich gleich ins Bett muss. Dazu kommt, dass mein neurodiverses Gehirn es gerne schwer macht, sich auf Dinge zu fokussieren.

#QGIS folks: any tips for creating balanced zones/territories?
I’m after an algorithm or plugin that can partition areas into regions of roughly equal size and equal potential (population, sales, etc.) based on underlying layers.
Pointers, docs, or workflows welcome! 
Gibt's eine Möglichkeit bei einer Karte Systematisch nach Gewässern zu filtern?
Ich liebe kleine versteckte Gewässer, winzige Waldseen Wasserläufe usw. Aber die tauchen auf Karten erst auf wenn eins nah ranzoomt, sofern überhaupt erfasst.
Manuell suchen sowie auf Zufall hoffen ist sehr ineffizient.
Geht das irgendwie einfacher?
based on https://chaos.social/@djh/114353061956304750 I present: #zbush - a very fast spatial index for 2D points based on a z-order space filling curve and BIGMIN search space pruning 
npm install zbush
