Orbital Commons
The active satellite catalog as one navigable field: browser-worker propagation, instanced rendering, selection, orbit trace, and ground trace.
LEO / MEO / GEO
FIELD / INSTRUMENT / LIMIT
Lab
Observe, compare, and reason through space.
OBSERVATORY
Observe changing systems and representations through declared sources, models, projections, time windows, and spatial extents.
Earth in Change
Recent Earth observations become a temporal sequence rather than a fixed basemap: the date is part of the image, not metadata outside it.
t → image
Geographic Flow Laboratory
One workbench compares continuous vector fields, aggregate origin–destination networks, timestamped trajectories, and Lagrangian releases without pretending they are the same geometry.
field / OD / x(t)
Earth Pulse
A live earthquake field rendered on a self-owned world view. Magnitude, depth, and recency become a changing pulse rather than a generic alert map.
M / km / t
Image → Trace
A small figure engine that turns a field-like image into contours, regions, and traces. It asks when an image begins to act like a map.
image → trace
World as Relation
A world field treated as authored geometry rather than a borrowed basemap. Projection changes the visible relation; geography begins where the choice becomes explicit.
world / relation
Water as Spectrum
An interactive water-colour theory instrument. Change water and atmospheric state, sample a synthetic TOA signal, then invert it with deliberately right or wrong aerosol assumptions.
λ / a / bb / Rrs / ρTOA* / Rrs_est
PLAY / SPATIAL REASONING
Practice location, boundary, adjacency, and path reasoning through direct geographic feedback.
Locate
A location exercise that returns error as distance and direction. The aim is not recall alone, but calibration: where did your mental map bend?
φ / λ
Zone
Find a named country from its position among neighbors. Shape matters, but relation to the surrounding field matters more.
Trace
Cross the world by shared land borders. A route is not a line drawn over space; it is a sequence allowed by topology.
A ↔ B
Project
Predict first, then drag the representation and watch the same geography change appearance.
predict / transform / reveal
Light
Break the light path. Remove scattering, backscatter, or reflection and observe what remains.
source / path / observer
Swath
Change altitude, field of view, and detector sampling. See why wider coverage does not come free.
altitude / FOV / GSD
Every instrument declares what it can see — and what it cannot.
OPEN-SOURCE BUILDS
Engineering tools behind the practice.
GEOSPATIAL DEBUGGINGGeoDebug
Finds geospatial bugs ordinary tests miss.
