NASA Earth Day/Night Images
We serve two NASA image products: The Blue and Black marble mosaics. We have filtered and down-ampled those as well at the same resolutions that are available for the Earth DEMs. However, all images are pixel-registered only.
The available resolutions for this image are:
"01d", "30m", "20m", "15m", "10m", "06m", "05m", "04m", "03m", "02m", "01m", "30s"
. Where the suffixd
,m
ands
stand for arc-degrees, arc-minutes, and arc-seconds. See also the manual of remotegrid for information about the grid registrations.
On first usage, the grids are downloaded to the user ./gmt/server/...
directory. On later usages, the image(s) are loaded from that local directory.
Refer to earth_daynight for more details about technical detail, available resolutions, sizes, version information and references.
Example
I = gmtread(remotegrid("day", res="6m"))
viz(I)
or for the night images
I = gmtread(remotegrid("night", res="6m"))
viz(I)
