#30DayMapChallenge Day 30: Makeover 🏔️
This is it! Thirty maps in 30 (ahem… 35) days.
For today’s prompt I revisited a map I started in the 2024 challenge, when I only managed to complete the coastline. This time, I gave it a proper makeover using the 1:250k LINZ contours
#30DayMapChallenge Day 29: Raster🎨
Today is a “paint by numbers” raster grid of soil moisture based on NASA’s SMAP. Shout out if you’d like a copy to “paint” yourself. Soil moisture is a key piece of the flood puzzle: when soils are already saturated, floods can escalate fast.
#30DayMapChallenge Day 28 Black ⚫
For today’s prompt I worked entirely in black, letting texture and material determine the map’s form. Three layers come together to depict the buildings, roads and background of Te Herenga Waka Victoria University of Wellington’s Kelburn campus.
#30DayMapChallenge Day 27: Boundaries 🍮
The Hutt River flood extent in Jello and wafer paper. The coastline is often represented as a hard line on maps, and I played with the idea of rethinking permeable boundaries.
#30DayMapChallenge Day 26: Transport 🚣♀️
Today’s map charts Wairarapa Moana in beads. Each bead represents 10 sq km. The lake was an important part of pre-colonisation transport for Māori, connecting communities, resources & seasonal movements across the landscape.
#30DayMapChallenge Day 25: Hexagons 🔷
I started this hexagon map for the 2024 challenge but didn’t get very far at the time. This year I finished the stitching and added the legend.
The map shows population density change from 2018 to 2023 using New Zealand Census data.
#30DayMapChallenge Day 24: Places & Their Names 🏞️
I want to introduce you to Wairarapa Glistening Water. A co-designed website that weaves video, audio, text, VR & maps to allow 5 wetlands to tell their kōrero (stories). Co-designed w Ngāti Kahungunu ki Wairarapa
#30DayMapChallenge Day 23: Process 🧵🗺️
Today’s post is less about the final map and more about how it came to be. Turning soil lead concentration data into a field of crocheted hexagons.
Data sources: GNS Science Report 2023/23 & LINZ
#30DayMapChallenge Day 22: Data Challenge: Natural Earth🌏
Today’s map of plate boundaries is created from string and beads on paper. The Natural Earth dataset, recentered on Aotearoa New Zealand, is shown using an equal-area projection. Pacific grouping boundaries also shown.
#30DayMapChallenge Day 21 Icons⚽
Today's map shows focal mechanism diagrams (based on moment tensors) for earthquakes in New Zealand from 21 Oct to 21 Nov this year. Each of the 11 ‘beachballs’ shows the style of faulting and the direction of slip during each earthquake.
