#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. Additonal data: ESRI

#30DayMapChallenge Day 21 Icons⚽
This map shows focal mechanism diagrams (based on the 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. Data: GeoNet (John Ristau)

#30DayMapChallenge Day 20: Water 💧
Today’s map uses free-motion quilting techniques on paper to trace part of the flood extent from Cyclone Gabrielle earlier this year. The blue organza overlays the aerial imagery, letting the landscape show through while evoking the shimmer and movement of water.

#30DayMapChallenge Day 19: Projections🏖️
I cannot take credit for today’s “map”. Our wonderful Felipe Perez has been getting the School’s augmented reality sand table up and running again. The sand table is an amazing way to talk with future students about basic spatial concepts.

#30DayMapChallenge Day 18 – Out of This World 🌕

Today’s attempt was meant to be a glow-in-the-dark 3D print of a lunar DEM. Instead, the printer gods intervened.

Failure is part of the research process, though, and this is what we got: an out-of-commission printer and some ideas for the future.

#30DayMapChallenge Day 17: A New Tool 🧵🌋

Today’s map stitches together the deformation pattern underlying Lake Taupō. The thread trace uplift and subsidence observed over 42 years of lake-levelling surveys, revealing how dynamic the volcano remains beneath the surface.

#30DayMapChallenge Day 16: Cell – The Risk of Rising Water 🌊
Today’s map stitches together a view of flood risk in Lower Hutt, with a thread grid atop a printed map underlay.
Data: GWRC, LINZ, Eagle Technology.

#30DayMapChallenge Day 15: Fire 🔥
For today’s map, I leaned into the theme and used fire to map fire. New Zealand saw a substantial wildfire in Tongariro last week; though still around 2,000 hectares smaller than the 2020 Lake Ōhau blaze mapped. (note Ōhau isn't the largest wildfire - oophs)

#30DayMapChallenge Day 14: OpenStreetMap 🌐

Today’s (slightly late due to grading!) map plays with the idea of layers by using stacked overhead transparencies to physically build the map piece by piece: OSM building outlines and tsunami risk zones.

#30dayMapChallenge Day 13 10 minute map: 10 minutes from campus?

In 10 minutes, distance bends to pace and terrain - on flat streets, a slow wander might take you 600 m, a steady walk 800–900, and a brisk stride up to 1.2 kms. But Wellington isn't flat...

#30DayMapChallenge Day 12: Map from 2125

IPCC’s projections for June - August 2021–2040 temperatures under SSP3-7.0

White: 0.5°C
Pink: 1°C
Red:1.5°C
Dark red: 2.5°C

I went off-prompt and imagined: global temperature change has stabilised at no more than +2°C

#30DayMapChallenge Day 11: Minimal Map – Hikurangi Subduction Zone 🪡

A single sweeping line of tambour beading traces where the Pacific Plate dives beneath the Australian Plate along Aotearoa’s east coast.

The Hikurangi Subduction Zone is New Zealand’s largest and most active fault boundary.

#30DayMapChallenge Day 10: Air – Blown Away: Wind Zones in Porirua City 💨

Using coloured pencil, this map shows how wind exposure varies across Porirua from calmer pockets to very high and specific-design areas.
Designing for hazards is a complex problem. ✏️

#30DayMapChallenge Day 9: Analog🗺️

This hand-drawn chalk map of Wellington City highlights the active faults that define our region’s landscape and seismic risk. The map traces how the city is shaped by the complex boundary between the Pacific & Australian tectonic plates. Data from GNS Science.

Each tiny resin ‘diamond’ marks a cell that includes a tsunami evacuation zone. Red zones take priority; if even a small part of a cell falls inside, the whole cell is red 🔴.

#30DayMapChallenge Day 7: Accessibility🌄

What we see shapes what we value. Not everyone experiences the landscape in the same way. This visibility map of the Ruamāhanga catchment shows which areas are most and least seen from roads. 3D printing the terrain to make the landscape more accessible.

Day 6: Dimensions #30DayMapChallenge

Each air-dry clay hexagon was hand-crafted during a Critical Signals workshop on exploring risk and resilience. Each participant shaped their area based on an aerial photograph & when pieced together, the city takes form: imperfect, dimensional, and human.

🪡🌏Day 5: Earth #30DayMapChallenge

This cross stitched map shows the soil drainage patterns of central Wellington and Miramar, based on Land Environments of New Zealand (LENZ) data.

#30DayMapChallenge Day 4: My Data – The Illusion of Support ❤️💙

This map comments on political echo chambers using a red filter. National had the highest percentage party vote in 2023.

People tend to form relationships with others with similar views, which can make election results feel surprising.

#30DayMapChallenge Day 3: Polygons:
WREMO Region in Fabric 🧵

Eight local authorities make up the Wellington Region Emergency Management Office (WREMO) - working together to respond to floods, earthquakes, & other emergencies.

Day 2: Lines – The Secret Life of Streams 💧

UV light reveals piped streams.

Early Wellington was shaped by streams flowing to the harbour. As the city grew, many were piped underground, hidden from sight but still running beneath our feet.

Day 1 #30DayMapChallenge: Points 🧵🪡

I created a hand-felted map of Wellington showing Community Emergency Hubs as buttons, using locations from the GWRC web map viewer (via the Natural Hazards Portal).

It is roughly to scale, offering a soft, tactile take on community resilience. 💚
