this is a VERY enhanced and cleaned up map
with the missing data filed in with the data from "Marc Buie's et al"
based on "PIA19956" and "PIA19858"

2k lores ( 0 to 360 !!! )


16k zip

looking cold and very detailed. Could be that there is a bit too much icy blue compared to these NewHorizons extended color images?:




To me these "enhanced color" images look more appropriate than the official natural color ones

this July the first set of NH data will be on PDS
then next April and Next 2017 July the rest of the data

until then all we have are stretched jpg's

Here are John's extended color Pluto texture in comparison with my natural color version, both reduced to 2k size. Should be good enough for comparing the very significant color differences. The natural color makes Pluto look definitely "warmer" than the icy extended color variant

@John:
At the 16k texture level I noted significant pixel shifts (both in x and y directions) of your texture compared to the official rectangular one in extended color: i.e. PIA19956
My 16k Pluto texture (natural colors) is OK in this respect. Any ideas?

for these i use Gimp and the polar projection remapping can move things a few pixels the first time it is remapped ( and i use cubic interpretation in gimp )
isis3 ( cam2map & map2map ) also can do this if cubic or bilateral pixel reinterpretation is used
in isis you need to use "nearestneighbor" to keep that from happening to much


For areas near the poles where this happens i really have never seen a issue in Celestia with a texture remapped with gimp and a DEM remapped using ISIS3

now if you are referring to a bit of image offset
this is a blend of two images
PIA19956 ( for color layer on the B&W )

John,

your above 16k rectangular Pluto texture (extened color) is offset by quite a few pixels relative to the official texture (PIA19956) from which it originates. The offset is far from the pole in this best studied central-equatorial region of the rectangular projection:


To quickly check for yourself, reduce PIA19956 to 16k, load it along with your above final 16k texture as (superimposed) layers into GIMP and then reduce the opacity of the top layer to 50%.

Fridger

As to Charon in extended color, I started like JohnVV from the 4k texture that Steve Albers has projected to rectangular form about one year ago and uploaded to the UMSF forum:
http://www.unmannedspaceflight.com/inde ... t&p=227014
Then I continued my way to eliminate nasty transitions between hires and lores regions. I also applied various wavelet filters etc. The result looks quite pleasing I think (despite being only 4k in size). Here is the size-reduced 2k texture
[Click first on the image (1-2 x) and then hit the fullscreen key of your browser (F11 for FF)]


Unlike JVV I always prefer to fill regions where observations are lacking with a uniform color that represents the color-average of the (non-empty) texture. This way, one easily notices that data are missing, yet the respective transitions are rather smooth...

Finally, have a look at a "kingsize" (1920x1080) screenshot with the new Charon in the center and Pluto (=> JVV) in the background.

As a comparison, here is the official photo of Charon in extended color as of 10-1-2015 and in unnaturally bright illumination


Enjoy,
Fridger

PS: If there is interest, I'll make a .zip with the 4k texture for downloading.

I'm very interested.

Very nice guys.

Is 4K the highest resolution that's been published so far?
I'm not sure if Horizons completed transmission of all it's data yet. If not, then perhaps there may be yet higher resolutions to come in the future...I hope so anyway.
NASA and JPL always put everything in the public domain as far as I am aware.

... and judging by that official photo, I think Charon will need a mesh as well!

John will have to comment on the availability of high resolution mosaics. I'm guessing he's made a few himself.

The Ralf imager uses CCDs which are 5024x32. For details, see http://www.boulder.swri.edu/pkb/ssr/ssr-ralph.pdf (technical publication) and http://www.ball.com/aerospace/Aerospace ... f?ext=.pdf (popularized description by Ball Aerospace [no relation ] )

The last of the New Horizons data is not expected to be downlinked until almost the end of 2016. They're currently expecting to have a Post-Encounter Pluto System Science Conference in November, 2017.

These dates are mentioned in the New Horizons timeline at http://pluto.jhuapl.edu/Mission/

the data will not be released for 1 year after all the data is down -- that will be this winter( think early 1980's telephone modems )
so the winter after NEXT we will have access to it on PDS

all i did was use the color image to colorize the B&W and add in the southern data ( Marc Buie et.al)

so other than looking at a possible mismatching and a bit of miss alignment ( the Prime Meridian is still NOT official )

yes i do make some rather BIG maps
" You just won't believe how vastly, hugely, mind-bogglingly big they can be "

current is Mercury at 256 pixels per degree


as to pluto
this is the current highres map

Hello John.

Do you happen to have a version of the 16k Pluto map with a zero degree central longitude, so that it can be accurately used in Celestia?

Thanks.

you can offset it easy enough
open in Gimp
select :
/layer / transform / offset

in the menu
and offset x by 8192 px

but for a large image you WILL want to use a "virtual texture"
there is a whole section devoted to this

This new, detailed global mosaic color map of Pluto is based on a series of three color filter images obtained by the Ralph/Multispectral Visual Imaging Camera aboard New Horizons during the NASA spacecraft's close flyby of Pluto in July 2015. The mosaic shows how Pluto's large-scale color patterns extend beyond the hemisphere facing New Horizons at closest approach- which were imaged at the highest resolution. North is up; Pluto's equator roughly bisects the band of dark red terrains running across the lower third of the map. Pluto's giant, informally named Sputnik Planitia glacier - the left half of Pluto's signature "heart" feature - is at the center of this map.
