3D surface of the land and ocean floor

[SAZAR]

Can someone point me to 3D model of surface of the land and ocean floor of the Earth,
or a grayscale elevation map so I could make my own 3D model from it.

I was curious - I wanted to play a bit with such "flat" (rectangular i.e. not spherical) 3D model of Earth's relief by placing a flat surface (that is: ocean surface) parallel to it intersecting with relief features at different levels so I would see how would Earth map look like with different ocean levels.

(I mean - imagine: new islands, new continents and other features - like some other planet!)

If someone already made that - I would like to see so give me some link - if not - give me material (grayscale-value elevation map in high enough resolution, but not too large) and I'll make it - no problem!

Google Earth 5 introduced 3D models of the ocean floor.

Is that sufficient?

Hello there!

I found a few resources that might be helpful for your project.

1. The US Geological Survey (USGS) has a website called EarthExplorer where you can search for and download elevation data for different areas of the world. You can select the format you want the data in, including grayscale elevation maps. Here's the link: https://earthexplorer.usgs.gov/

2. NASA also has a website called Earth Observing System Data and Information System (EOSDIS) where you can find various datasets, including elevation data. Here's the link: https://earthdata.nasa.gov/

3. Another option is to use Google Earth Pro. It has a feature where you can view elevation data in 3D and adjust the sea level to see how it affects the land and ocean. Here's the link to download Google Earth Pro: https://www.google.com/earth/versions/#earth-pro

I hope these resources help you in creating your 3D model of the Earth's surface. Happy exploring!
