Some areas around Athens have received over 100mm of rain.
Is Europe ready for extreme rainfall that climate change will bring ?

Deze wijkt qua technieken en datalagen nogal af van wat ik normaal maak. Heb deze destijds gemaakt met de tutorialvideo van @qwast-gis.com.
Als ik dit nu opnieuw wil doen, moet ik die video weer helemaal opnieuw volgen. Want ik snap nog steeds niet helemaal hoe dit me toen gelukt is.

#30DayMapChallenge Day 5: Earth🌍
#Groningen’s gas extraction and #Limburg’s mining caused seismic risks, which js now a political issue around damage & compensation. Made while teaching #QGIS & @merginmaps.bsky.social in Leek (Groningen) for #QWAST #Fervent & #Geo2Meet.

In terms of hydrology, the Kerrville catchment is hugh. In excess of 1300 square km ?
Extreme rainfall in that region has only one way to go.

Recently read about how the Structural Geophysics Tools (sgtool) QGIS plugin from Mark Jessell could analyse an RGB image file to create an associated greyscale image with correct values.
It showed how to use ChatGPT to analyse a legend colour bar and spit out colour strings.

Thx for @qwast-gis.com for his YouTube videos - as a result I was quickly able to refresh my memory about how to put different decorations on a map to aid understanding.

I recently made a new #QGIS plugin to calculate bounding boxes. I use Github Copilot for text autocomplete. And while editing the README file the AI thought my plugin was created by @qwast-gis.com. I'll take that as a compliment.
