|Blue Marble next generation layer for GE||baker99||10/16/05 11:42 AM|
Blue Marble: Next Generation offers greater spatial detail of the surface and spans a longer data collection period than the original. The original Blue Marble was a composite of four months of MODIS observations with a spatial resolution (level of detail) of 1 square kilometer per pixel. Blue Marble: Next Generation offers a year's worth of monthly composites at a spatial resolution of 500 meters. These monthly images reveal seasonal changes to the land surface: the green-up and dying-back of vegetation in temperate regions such as North America and Europe; dry and wet seasons in the tropics, and advancing and retreating Northern Hemisphere snow cover.
Blue Marble: Next Generation improves the techniques for turning satellite data into digital images. Among the key improvements is greater detail in areas that usually appear very dark to the satellite (because a large amount of sunlight is being absorbed), for example in dense tropical forests. The ability to create a digital image that provides great detail in darker regions without 'washing out' brighter regions, like glaciers, snow-covered areas, and deserts is one of the great challenges of visualizing satellite data. The new version also improves image clarity, and gives highly reflective bodies of water, such as salt lakes, a more realistic appearance.

Thats very cool. But why does my PageFile almost reached 950 MB? Luckly I have 512 MB of RAM to run the Blue Marble. You might make it for the Seven Continents instead of the Entire Globe.

I've written about the Blue Marble NG for GE at the Google Earth Blog.
You can read the story here.

Excellen thanks for the blog entry, hopefully the server can handle the load, it is a community funded server so of course it isn't extremely powerful, but so far our sysadmin has kept it running smoothly.

We are currently experiencing some hardware problems, but Google Earth access should be back soon, World Wind users should not be affected as the data is on a different server, thanks for your patience.

Ok you will need to update (re-download) the kmz file as it now points to a different server, enjoy.

The Blue Marble images described in this thread have not been working for some time. I'm hoping to see something new done soon.

Yes indeed! I like the new WMS server for the Blue Marble NG. I especially like the fact the images have been time stamped and that you can do a time animation of the different months of Blue Marbles. It even works well when zoomed in close (after you've given time for each month to load). Very cool!
I do see some weird anomalies when zoomed out to full globe views - where some of the images fail to load (get black areas).
I do wish the images were a bit brighter with stronger color saturation. But, otherwise this is a great move in the right direction.
The only other thing would be to use the <region> tags to cause the image to fade out when you zoom in close so you can see Google's normal images.

More dynamic data via WMS:
The daily MODIS composites, full 250m resolution, available directly from the source server:
TERRA MODIS daily, data collected yesterday around 10AM local, updates every day around 11AM Zulu
AQUA MODIS daily, data collected yesterday around 2PM local, updates every day at about 1PM Zulu
These layers use the raw, full resolution composites. They are generated every day from all the MODIS subsets available at MODIS Rapid Response System.
The composites are created as JPEGs, producing transparent PNGs would be larger and slower, and would also take longer to create.
Yesterday's TERRA MODIS on the current month BMNG This is a pre-blended layer that updates much later than the TERRA composite (if at all).

These MODIS network links are great! Thank you so much for releasing these! I see lots of possibilities!
