Why We Built a Space-GIS Curriculum From a Hawaiʻi Perspective

Mon, 11 May 2026 00:00:00 +0000

When we shipped LaunchDetect Academy — a free 30-week space-GIS curriculum — most online courses position their work as universal. A coordinate system is a coordinate system. A satellite is a satellite. The pedagogical assumption is that the math is what matters and the place doesn’t.

We disagreed. Today, the academy ships with explicit place-based framing for every week, written for Hawaiʻi-based learners and Pacific Islander youth as the canonical audience. Other learners are welcomed, of course — but the curriculum names where it comes from.

Here’s why.

Coordinate systems didn’t begin with WGS84

For roughly 3,000 years before any European cartography existed, Pacific peoples navigated the world’s largest ocean using stars rising and setting at specific points on the horizon, ocean swells refracted by the islands they passed, the seasonal flight paths of nesting seabirds, and the changing feel of the swell against a canoe’s hull. The Polynesian Voyaging Society’s Hōkūleʻa — a 19-meter double-hulled voyaging canoe — has been sailing using these traditions since 1976, including a four-year worldwide voyage from 2014 to 2017.

That is a coordinate system. It works. It is verifiable. And it was — and is — a complete intellectual tradition belonging to the people who developed it.

WGS84 (the satellite-derived geodetic system that GPS uses) was finalized in 1984. It is one way to describe where a point is on Earth. It is not the only way, and it is not “more true.” It is just precise to a millimeter and machine-readable.

A space-GIS curriculum that treats WGS84 as the only way to know where you are is incomplete on its own terms. So we wrote one that doesn’t.

What this looks like in practice

Every week of the academy opens with a place-based question — something like “When your kupuna give you directions to a place, do they say latitude and longitude — or do they say it differently?” — then a “Connecting to Hawaiʻi” sidebar that grounds the week’s technical concept in local institutions and tradition.

Some examples:

Week 1 (coordinate systems) points at Pacific wayfinding alongside WGS84 — same Earth, two complete traditions for describing it.
Week 13 (GOES-R imagery) points out that GOES-18 is the satellite stationed directly south of Hawaiʻi watching the eastern Pacific 24 hours a day. It’s your satellite.
Week 14 (Band 7 thermal IR) explains that the same physics — Planck inversion at 3.9 µm — that LaunchDetect uses to detect rocket plumes is what the USGS Hawaiian Volcano Observatory uses to track Kīlauea lava flows.
Week 19 (real-time GIS) anchors WebSocket streaming to the Pacific Tsunami Warning Center in ʻEwa Beach, which delivers alerts to ~50 Pacific Island nations.
Week 22 (machine learning for satellite imagery) points at U-Net for coral bleaching detection at the Hawaiʻi Institute of Marine Biology in Kāneʻohe Bay.
Week 23 (SAR / InSAR) is built around HVO’s use of Sentinel-1 InSAR to track Kīlauea’s pre-eruption uplift.
Week 24 (geodesy) uses Hawaiian tide-gauge records (Honolulu, Hilo, Kahului) — among the longest-continuous in the Pacific — as the worked example.

The academy also includes a deep-dive essay connecting Pacific wayfinding traditions to modern space-GIS coordinate systems explicitly. And a 44-term glossary that includes Hawaiian/Pacific terms (ʻāina, ahupuaʻa, kuleana, wayfinding, Hōkūleʻa, mauka/makai, Mauna Kea, Kīlauea, Indigenous data sovereignty) on equal footing with the Western technical terms (WGS84, SGP4, GOES-R, EGM2008, MGRS, ITAR).

Pedagogy — not decoration

Place-based framing only works if it teaches something the abstract framing can’t. Some examples of where the Hawaiian context does actual conceptual work in the curriculum:

The wayfinding-WGS84 pairing teaches that coordinate systems are cultural objects — they answer “where am I?” by way of a particular question, not the only question. This is the foundation for understanding why so many Sentinel-2 false-color rendering decisions are arbitrary choices, why MGRS exists alongside lat/lon, why a project CRS is always a decision.
The HVO–LaunchDetect pairing for Band 7 teaches that the same physics serves multiple use cases — there’s no “rocket plume detector” technology separate from “lava flow detector” technology; there’s brightness temperature thresholding applied to different scenes. Generalizes the methodology far beyond launches.
The Indigenous data sovereignty entry in Week 28 explicitly raises the question — when you build a tool that can map any spot on Earth, who decides what gets seen? This is not a footnote; it’s the central ethical question every GIS engineer should be thinking about, and Hawaiian/Pacific contexts have some of the deepest practitioner traditions for engaging it.

For educators

The academy is free for classroom use — no license required, attribution welcomed. We’ve written a teacher’s guide with three pacing models (extra-credit, semester elective, single-topic deep-dive) and lab logistics for educators who don’t have a strong CS background themselves.

If you teach in a Hawaiian-immersion or Native Hawaiian education context: the place-based framing is intentional and you are absolutely the expert on what works in your specific classroom. The reflection prompts are starting points — rewrite them to match the conversations your students are having. Pull requests adapting the Hawaiian framing are explicitly welcomed at github.com/ops-sketch/academy-labs.

Why this matters more broadly

Every place has a coordinate system that predated WGS84. Every place has an ongoing community that maintains traditional ways of knowing where things are. Space-GIS curricula that ignore these and present the WGS84-and-Web-Mercator stack as universal are teaching students one tradition while pretending it’s the only one.

The math is universal. The voice is not. We’ve tried to build a curriculum whose voice names where it comes from, on the conviction that doing that produces better technical educators — practitioners who can hold their tools accountable to the places where the work matters.
