There's a new blog post about the new terrain mapping & compression tool.

You can find it here: http://outerra.blogspot.com/2011/04/new-terrain-mapper-tool.html

Very Nice!!!
Question: do you also map coastal lines in this tool? Because netherlands werent possible to show due to that it is beneath MSL...

No, not yet.
I'm not entirely sure how to handle it. For the ground level views to render correctly, there simply should be dikes that stop the water from flooding the area, not just some magic that masks the water out of a region. Applying coastal lines there would mean creating the dikes, but their size is below the resolution of terrain data and thus would have to be created separately in a vector layer - for example by placing a kind of road around them, elevating the terrain. Or it could be another stage that patches coastal regions only, smoothing the shores everywhere.

I feel like making a T-Shirt that says...


I use a variant of quadrilateralized spherical cube projection, along with wavelet-based compression to process my data.

Wow!  200 X faster does sound like a little more than just an improvement!  :D

When do you think you will have the video out comparing the old datasets?

It's not a video, but screens comparing the same locations now and then. I have them almost ready.

There will be some video from Angrypig though, if he ever comes through the phase of him saying - "I'm just going to fix/add this and that before making it" :)

No need. Sometimes people need a little motivation. That includes calling them out in-front of an audience.

...

So hows that video coming along?

LOL!

Nice screens.  I can see a HUGE improvement in the before and after shots.  Can't wait to fly through terrain in the demo.  I've actually bitten off quite a few fingernails waiting in anticipation.

A quick question about the video:  Why did the water areas process so quickly if there's land under the water?

Underwater terrain comes with 1km resolution, whereas the land data have 90m or better. When processing oceans, the tool doesn't have to go so deep (in quad-tree hierarchy) as with the land, which results in the quicker processing.

Excellent news!

No it seems that northern part of Europe will aslo get better elevation data..
Cant wait to see the results in Norway..

Keep it up, will be sure to follow this thread....
