Earth Console Guide

What this version is trying to be

A globe for asking, “where was this place when the continents were somewhere else?”

Earth Console combines a realistic present-day globe with reconstructed deep-time and present-day layers. The central idea is not just to show a dot moving through time, but to let that dot sit in context: modern borders, ancient coastlines, plate outlines, rough motion directions, and boundary zones can be switched on or off depending on the question.

The Three Time Regimes

Geologic past, -250 Ma to -10 Ma: Uses GPlates Muller2019 data for reconstructed place positions, coastlines, and plate polygons. This is the most science-grounded part of the prototype.
Present, 0 Ma: Uses the realistic Blue Marble-style Earth texture plus Natural Earth modern country borders. This is the reference state everything passes through.
Future, +25 Ma to +250 Ma: Uses broad hand-authored continent drift vectors. It is deliberately labeled scenario mode because future plate evolution is uncertain and model-dependent.

What The Timeline Does

Dragging the timeline changes the active reconstruction year. The top readouts tell you which model and layer family are being used. Expedition buttons are shortcuts to useful moments: Pangaea, Cretaceous, Today, and several future scenario jumps.

The Play button increments time continuously. In the past, the app loads the closest cached GPlates snapshot; between snapshots, tracked places interpolate smoothly while coastlines and plates step between the nearest available reconstruction.

Focus: Places And Countries

The Focus selector chooses the active object. Cities use their present-day coordinates. Countries use the Natural Earth label point, which is roughly a country centroid suitable for tracking the country as a representative point.

This means “Ireland” is not every rock in Ireland deforming perfectly. It is an approximate track for Ireland’s present-day country label point through the reconstruction model.

Lenses

Planet: The home for Earth systems: land, ocean, terrain, tectonics, atmosphere, climate, ice, hydrology, and other natural-system layers. Tectonic data is a layer family inside this lens rather than a separate top-level mode.
Political: The home for human systems: countries, cities, borders, population, routes, trade, air travel, and related datasets. Deep geologic time is not the natural default for this lens.
Game: The future home for playful edits and world-changing tools. The current build uses this lens for the game-style surface prototype: bright country regions, close zoom, walking controls, and a small avatar. Later versions can add actions such as changing borders, raising sea level, adding mountains, or modifying coastlines.

Layer guide

What Each Switch Means

Layers are data elements, not lenses. Each layer has its own time domain, so a layer that is meaningful today may need to hide, freeze, switch source, or show a caveat in deep time.

Reconstructed land

In the past, this draws GPlates reconstructed coastline traces on a neutral ocean base. It avoids treating coastline rings as a solid land mask, because those rings can wrap oddly near seams and poles at supercontinent times. In the future, it draws scenario-shifted modern land.

Country borders

Shows modern Natural Earth country boundaries. Useful for recognizing present-day countries, but it can be conceptually misleading in deep time because political borders did not exist. In the new model this is a Human Systems layer rather than a planet-science layer.

Plate polygons

Shows GPlates topology snapshots. These are plate-model surfaces, not country or coastline shapes. They help explain which moving plate region a location belongs to.

Plate motion

Surface arrows indicate broad plate motion. Longer arrows represent faster plate movement, and the animated glow under each arrow shows direction. They stay close to the globe surface, more like a wind-direction chart, so they should be read as motion across the crust rather than flight paths above Earth.

Orientation grid

Adds external pole extensions, meridians, latitude guides, and a highlighted equator. This is meant to help you stay oriented when the familiar present-day surface texture is replaced by reconstructed coastlines.

Boundary zones

Highlights a few recognizable modern tectonic interactions: the Mid-Atlantic Ridge, Himalaya, Andes, and East African Rift. This layer is educational scaffolding, not a full global boundary dataset yet.

Selected trail

Draws the active place or country track between present and the selected time. It helps answer “how did this place get from there to here?”

Reference trails

Adds a small set of comparison tracks for saved places. It is off by default because multiple trails can look like accidental ghosts when you are focused on one country.

Labels

Shows the selected object label and boundary-zone labels on the globe. If Reference trails are on, their labels may also appear.

Atmosphere and Star field

Purely visual depth cues. They make the globe feel spatial and alive, but they do not change the scientific data.

Future layer families

Day/night, rainfall, ice sheets, sea level, climate, and hydrology should be added as Planet layer families with explicit time-validity rules. For example, current rainfall climatology should not be shown at 200 Ma unless a paleo climate source supports it.

How To Read Ireland Through Time

Select Ireland in Focus.
Leave Reconstructed land, Selected trail, Labels, and Plate polygons on.
Jump to Pangaea or drag into the geologic past.
Watch the Ireland label and trail relative to the reconstructed coastlines.
Return toward Present to see the track reconnect with the familiar modern North Atlantic.

Good Feedback To Give

Useful feedback can separate visual confusion from model limitations. For example:

“I understand this is an approximate centroid, but the label placement is hard to read.”
“The coastline layer helps, but I need clearer land/ocean contrast at 250 Ma.”
“Plate arrows are useful, but I cannot tell whether they mean past motion or future motion.”
“Country borders in deep time are helpful as references, but they should look less official.”

Known Limits

The future is a scenario sketch, not a validated prediction.
Country tracks use representative points, not full deforming country shapes.
Boundary zones are a small curated set, not a global plate-boundary database.
Reconstructed coastlines and plate polygons update by cached snapshot, not continuously every year.
Modern political borders are useful for recognition but historically inappropriate in deep time.

Data Sources

GPlates Web Service, Muller2019 model: past points, coastlines, and plate polygons.
Natural Earth 1:110m: present-day country geometry and labels.
Local scenario vectors: future land drift and future motion arrows.

The app precomputes data into /public/data, so ordinary use does not depend on live calls to the GPlates service.
