Day 1: Points
Utilising POINT cloud data for Rakiura with the digital terrain model (DTM)... as well as Ackers POINT
The tale of Lewis Ackers is a fascinating one. Lewis, who was raised in a wealthy family with a sizable estate in New York, decided society life wasn't for him. In an effort to instil some discipline in him and curb his wild behaviour, his family agreed to let him sail away. They had no idea that they would never again see him. Around 1831, he arrived in New Zealand as a harpooner on an American whaling ship and immediately fell in love with the south. He started building boats after working at shore whaling stations and finally moved to Stewart Island with his Māori wife, Mary Pi, after buying 600 acres of property there from Chief Tuhawaiki.
There he constructed Ackers Cottage, one of the island's first stone homes, albeit it is still unknown exactly where he got the stone from to pull it off.
Until the late 1850s, Acker and his wife resided in this cottage. Since then, it has served as a workshop, smithy, storage, and brewery. Since then, Heritage New Zealand and the Department of Conservation have repaired it as an example of an early vernacular architecture and added it to the list of historic places in the country (Category I).
Day 2: Lines
CoastLINE; removing vertices till it looks silly...
Day 3: Polygons
Aotearoa - New Zealand's Public Conservation Land; its Mineral Mining Permits; and where they overlap.
At the risk of getting political... #NoNewMines

Day 4: Something 'Green'
Aotearoa - New Zealand's Renewable Energy Generation
The size of the dot corresponds to it's energy output in megawatts (MW). 105 generators of green energy around the motu, from Meridian Energy's Manapōuri Power Station (800 MW) to Watercare Services Limited's Rosedale Solar Array (1 MW).
Ministry of Business, Innovation and Employment (MBIE) reports that the share of energy supply from renewables is at a record 30-year high. Its reporting “shows the share of energy supply from renewables was 40.8% [in 2022], the highest since reporting started in 1990. Twenty-eight % of energy consumption also came from renewables, the highest it has been since 2016.”
The renewable share for electricity generation increased to 82.1% for 2021, up from 81.1% in 2020.
Day 5: Ukraine
The Ukrainian flag is a stylised field of sunflowers with a bright blue sky.
In terms of worldwide annual Sunflower seed production, Ukraine comes a close second with 15,254,120 tonnes produced annually (behind the Russian Federation with 15,379,287). A total land area of 5,958,900 hectares, and a total production of 361 kg per person!
The Russian Federation and Ukraine produce together more than 50% of world's total sunflower seed.
Day 6: Network
Aotearoa - New Zealand's network of High Pressure Gas Pipelines
Day 14/16: Hexagons & Food/Drink
Aotearoa - New Zealand's Livestock numbers (2017)
This indicator measures the numbers of farmed dairy cattle, beef cattle, deer, and sheep over time nationally, by region, and territorial authority, and approximates the density of these livestock across New Zealand.
Day 26: Island(s)
The islands of Tuvalu made news this month as they turn to the Metaverse to create a digital twin of their islands as Climate Change takes hold.
This map shows the islands of Tuvalu and their respective populations (in brakets).
Addressing world leaders at Cop27, Tuvalu’s Minister of Foreign affairs Simon Kofe said his country may cease to exist if climate change continues unchecked.
Last year, Kofe urged global leaders to “take bold and alternative action today to secure tomorrow” at the Cop26 climate summit while standing knee-deep in the sea to illustrate how Tuvalu is on the front line of climate change.
At Cop27 Kofe showed a digital rendering of the main island Funafuti, saying that if Tuvalu could no longer exist in the physical world, then it would find its place in the Metaverse.
“As our land disappears, we have no choice but to become the world’s first digital nation… to keep [Tuvalu’s population] safe from harm, no matter what happens in the physical world, we’ll move them to the cloud.”
Day 28: 3D
Te Wāhipounamu ("the place of greenstone") is the name for South West New Zealand's World Heritage Area. This area contains Te Rua-o-te-moko ("the place of shadows") or Fiordland National Park.
The Manapōuri Power Station (operated by Meridian Energy) is located at the western most arm (West Arm) of Lake Manapōuri; right on the edge of Fiordland National Park. Water falling vertically for 200 metres in vertical penstocks feeds seven 122 MW turbine generators; generating an operating maximum station output of 800 megawatts (enough electricity each year for about 619,000 average New Zealand homes).
This water then enters two tunnels - twin tailraces that discharge the water to Deep Cove in Patea - Doubtful Sound. This alters the natural hydrology of the Waiau River as historically this water would have entered the river and been discharged south into Te Waewae Bay.

Day 30: Remix (Minimal)
Day 30 of the #30DayMapChallenge - Remix (Minimal)
50 metre contours of Horomaka or Te Pataka o Rakaihautū — Banks Peninsula
Three main overlapping shield volcanoes created the majority of the peninsula. 🌋
It’s a composite of two main eruptive centres, one originating in Lyttelton and the other in Akaroa; erosion by the ocean creating their respective harbours.
