Get a first taste of what will probably become the next level 3D maps / street view, using Gaussian Splatting to map environments in 3D.

In this demo, the detail level gets crude when zooming in, but that will become refined.

Use mouse-buttons to zoom, pan or rotate…

The #Topography plugin for #OSMAnd isn't #OpenSource, is it? 💔

I really would love to look up how it parses data and what formats it supports 😕

Cette infographie répond très bien à la question suivante :
Quel est le point le plus élevé sur notre Terre ?

Effectivement, il y a trois sommets car cela dépend du point d'origine considéré dans la mesure :

  • Si l'on mesure par rapport au niveau de la mer, alors la réponse est le mont Everest (Népal 🇳🇵)

  • Si l'on mesure par rapport à la base de la montagne, alors c'est le mont Mauna Kea (États-Unis 🇺🇲)

  • Si l'on mesure par rapport au centre de la Terre,alors c'est le mont Chimborazo (Équateur 🇪🇨)

Pour bien comprendre la mesure par rapport au centre de la Terre, il faut se rappeler que celle-ci a un modèle ellipsoïde de sphère aplatie aux pôles. Ainsi, les distances entre sa surface et son centre varient de 6 352 km (fond de l'océan Arctique) à 6 384 km (sommet du Chimborazo). Le rayon équatorial est de 6 378 km, alors que le rayon polaire est de 6 356 km.

"The Lunar Orbiter Laser Altimeter (LOLA) has collected and released almost 7 billion individual laser altimeter returns from the lunar surface. The LOLA data is used poleward of 79◦latitude as the elevation basemap necessary for calculating shading…”

“The Lunar Orbiter Laser Altimeter (LOLA) provides a precise global lunar topographic model and geodetic grid that serves as the foundation of essential lunar understanding.
This aids future missions by providing topographical data for safe landings and enhance exploration-driven mobility on the Moon. LOLA also contributes to decisions as to where to explore by looking at the evolution of the surface…”

Scenes from morning hike with my sis. Not shown: heavy fog and humidity! Not their usual Wyoming fare.

Full size print complete!
The culmination of years of learning #3dprinting, experiments, messing with map data and scripts, trying to learn CAD programs and other tools to combine everything so the trails could be printed on the terrain AND be accurate. Colored water is a bonus. “:^)

Another angle with a printed frame. I love how printing in this orientation layers become contour lines that you can trace between trails to compare elevations. Speaking of which, elevation is exaggerated about 3x, which I think does a nice job highlighting glacial artifacts of the area along with giving a sense of climbing effort for a given trail.
