here is the highly interrupted constant-scale natural boundary map of Phobos

Here is a constant-scale natural boundary map of Phobos; primary ridges are the map edge. A poster by Pam Clark, Phil Stooke and me to be presented at lpi week after next. this one doesn't fold to a very good likeness because it is a very compact map. I'll post another in a minute with extensive ridge boundary, which, I say with confidence although
I haven't had a chance to fold it up yet, will fold to a good likeness of Phobos.

"Presumably there is insufficient interest in panoramas generally among the wider public for the big software companies to provide it as a standard facility."

Above is meant to be a forum "quote." I've yet to fully absorb the posting format.

Once upon a time, a century ago or so, the Panorama was the hottest thing going, the biggest urban attraction before the era of the moving picture. And the panorama was indeed "connected at the ends," in giant viewing rooms to which a couple would stroll of an evening. World-wide travel was difficult, and this was a way to compensate. If I have my history straight a fellow named Frederick Catherwood produced in New York City Panorama viewing rooms on the order of 100 feet in diameter showing Jerusalem, for example, and, another, Mayan ruined cities.

Atlanta still has something you can still go to called the Cyclorama, a 360 degree Panorama painting depicting a pivotal moment in the civil-war-between-the-states battle of Atlanta.

It is really quite a shame, in my view, that our digital era -- we see 3-D inside a flat screen -- has seen the corruption of this term.

Yes, join those ends up, even if it's only a big enough circle you can stick your head into!

Here are two constant-scale natural boundary maps of Mars showing color topography.
CSNB maps are made by a geometrical method of my own devising. These of Mars were suggested by Rene de Hon at the 2003 ISPRS meeting in Houston.

The "Mars as a dale" CSNB map has as its edge the primary ridges of the southern highlands. It's the view from the top down, so to speak, from the edge of the map inward.

The Mars as a hill" CSNB map has as its edge the primary valley-lines of the northern lowlands. It's the view from the bottom up, relative to the edge of the map inward.

The dividing line of the crustal dichotomy thus occurs as a ring around the middle of each map.

The maps or as twins, mirrored points of view.

The accompanying cylindrical insets show the boundaries of the respective CSNB maps.

Cheers

Any chance of the CAD file being shared? The PDS release isn't the sort of thing that will drop into 3DS Max too easily

Doug,
What do you mean by "the CAD file"? By the "PDS release"? By "3DS Max"? By "I had a go with the net"?

I can easily provide higher resolution versions. Perhaps you mean that?

At present, a world map with constant scale natural boundary can only be made the old-fashioned way, that is, by hand, tracing lines on a object, or plotting points by measurement. All those trigonometric formulas you'll find in, for example, Snyder & Voxland's Album of Map Projections are not germane. You have to go back one more step to the Renaissance era, back when point-plotting of perspectives was a new science. Those are still the active tools for making CSNB maps -- creating the outline and subdividing the map's interior (usually into a grid of longitude and latitude). All the fancy eye candy, the satellite derived imagery, is added later.
Constant-scale natural boundary mapping is a method distinct from our 470-year-old Mercator-based tradition.
Not that it's impossible to digitize the process; indeed, with today's computers and 3-D input devices, it's not even a big challenge. It's just that nobody's done it yet.

Seems like these folks have already done it, just not a web available version. What would be different in the OneGeology Project, more detail?

Here is another way to see -- and think about -- the whole globe: with a map, of course. Some of the above posts have been map-like.
This is a constant-scale natural boundary world map of Earth.
Its boundary is a portion, the Atlantic Ocean portion, of the mid-ocean ridge. You might, if you want, follow along with what I learn is called "the Wilson cycle": where the spreading apart of the Atlantic Ocean floor will eventually push closed the Pacific Ocean. That idea, I also hear, is a lot of simplistic, anthropomorphic bunkum. I don't mean to take sides in any argument here, just to point out that with a little ingenuity world maps may be fashioned to illustrate ideas global in scope.
Something meant to address climate change, to reveal large scale patterns in meteorology, a CSNB world map edged by continental divides, for example, would look entirely different.

I'm new around here, and have only recently looked through the "new" rules. It's hard to imagine how this string of posts relates to unmanned space flight. But given the drift of this conversation, I just wanted to add this to the discussion of whole earth views of ther globe.

And here is a model, made from hardware cloth -- so it would hold shape a bit better than paper -- of the highly interrupted CSNB Eros map, along with comparison photos to a "real" Eros model. Thanks, by the way, to Peter Thomas, for letting me have the CAD-CAM Eros model.

Here is another CSNB map of Eros. Obviously, it has a much more extensive boundary set, and it folds to a very accurate replica of the asteroid.
If this were accurately loaded with Phil's mosaics, and folded up, the result would be a very fair representation of the asteroid. Like the 3-D animations you see in the computer, but one you could hold in your hand. (Call the earlier posted map CSNB_Eros_1, call this one CSNB_Eros_2.)
Eros_1 with Phil-mosaics will be a slightly "shrunken" version of the real thing.
Eros_2 with Phil-mosaics will be a so-to-speak hard-copy of the object.
Don't hold your breath, because a lot of tedious registration work would be required to locate Eros_2's edges within the mosaics. But the possibility is intriguing nonetheless. Eros-1 will hint at it.

Here is the CSNB map with, except at most of the poles, Phil's latest mosaic. I didn't realize how much more contrast is in this new mosaic than the old ones. Took me a few pastes before I realized I needed to redo the old, and I failed to download Phil's new poles posted above.

No one should loose sight that these CSNB maps are experimental formats. My ridge-edge is not in strict registration with Phil's lighting, to say the least, nor is my ridge-edge jam-on accurate from a digital model. All to say that those who try to cut and fold the map shouldn't expect, where the folded edges come together, the photomosaic to match perfectly.

I'll edit the post above with the folded-map pictures to add some tips for putting one together yourself.

Here are several views of the folded-up CSNB (constant-scale natural boundary) map of Eros. This map has not quite the same data set as that posted above -- there are no mosaic sections, and certain craters (bright-walled ones, I think, but I'll have to check) are shown in red. There are two classes of "red" craters shown: simple circles and circles with stars. At the moment I can't recall the distinction.

The point is to show you what you're going for if you give folding a go.

Cheers.

Folding Tips:
1) When cutting it out, leave a bit of paper as a tab on one side of the seam to fold under the pieces as they come together.
2) This "extra" paper (let's assume it is white) is inconsistent with the 3-D geometry -- you'll see what I mean as tries to bunch up on iteself -- so, to release the compressional stress make a series of short (transverse) snips from the edge of the white to the edge of the map.
3A) The little scissors that come with small swiss army knives work well for cutting.
3B) 1/4" clear scotch tape works well; the narrower the better. I'd use 1/8" if I could find it and were a fussier sort of person.
3C) Run the tape transverse across the seam, and only as often as you need to to hold it together. The touch or feel of folding up a CSNB map is, for many, counterintuitive at first. It is not like folding up, for example, a cube or a cuboctohedron.
Not to digress, but I once had a class of fifth graders, working in groups, successfully fold up CSNB maps of Earth; so you can probably do it too.
4) Joining the last sections is tricky because you can no longer get your fingers inside to resist the pressure you need to apply the tape. A narrow rod or straw (better with a ball on the end) can be poked in through a tape-gap antipodal to the spot you still need to tape and maneuvered into position to resist taping pressure.
I make a lot of these, so I bent a small (3/16") whorl at one end of a 10" length of piano wire, putting the other end into a file handle.

Here also is a series of photos of a "real" model of Eros with the edge of this CSNB map marked in white.

This is my first post so we'll see if this works . . . I've loaded the attachment, but I don't see it anywhere. Presumably it will show up when I post this? Or do I have to do something else to finalize it?
Here is a novel projection world map of Eros showing topography, ponds, and as much of Phil's mosaics as I've been able to paste in so far - all but the above mosaic.
The map is a "constant-scale natural boundary" map, made by geometrical methods of my own devising. After I learn a bit more about links I'll direct you some abstracts describing the method.
If you cut it out and fold it properly, where the various facets adjoin, it will make a fairly good model of the asteroid.
That is to say, the mapping method has inherent proto-topological properties.
And, that there is very little relative distortion of size and shape.
