Im looking for a map of every well imaged object in the solar system.

Well imaged as in seeing surface variations or better.

Im still looking for maps of these objects

Idas moon Dactyl
asteroid Annefrank
comet Tuttle
asteroid Juno
Jupiters moon Metis
Saturns moon Pan
Saturns moon Atlas
Saturns moon Pandora
Saturns moon Calypso
Uranian moon Puck
Neptunes moon Larissa
asteroid Geographos
asteroid Davida
asteroid Golevka
asteroid JM8
asteroid TU24
asteroid NY40
asteroid KY26
asteroid Eugenia
asteroid Braille
Neptunes moon Nereid
Asteroid Lutetia

Does anyone have a map or knows where a map is of anyone these objects surface.
If you know where one is please include the site on your post
And the map has to be cylindrical projection

If you're looking for global cylindrical maps, they're unavailable AFAIK. Shape models might be a different story. Several of the worlds you've listed have been too poorly resolved for detailed mapping (Annefranke, Calypso, Dactyl, Metis, Pan) , imaged very noisily (Puck, Larissa, Nereid), or imaged by radar (Geographos, ect.) Steins and Borrelly might be decent candidates though.

This forum has a few gifted contributors working on this subject...Phil Stooke has produced excellent maps of Eros and other irregular bodies, and arguably the best existing maps of Larissa, Proteus, and many other nonspherical worlds. Ted Stryk has managed to tease out subtle details from imagery that was otherwise practically useless. John van Vilet has contributed beautiful shape models and surface textures for Celestia, and probably the best existing cylindrical maps of Phoebe and Hyperion.

Welcome to UMSF, too! Hope this was somewhat helpful.

I can definitely provide these:
asteroid Annefrank
comet Borrelly
asteroid Juno
Jupiters moon Metis
Uranian moon Puck
Neptunes moon Larissa
Neptunes moon Nereid

I can also provide a few worlds you didn't list.

Can you provide a link please?

I recently made a cylindrical map of Borrelly based on an image with a grid overlay that appeared on a poster by Randy Kirk at LPSC last year (Thanks Randy!) - but it's not finished yet. I need about 3 lifetimes to do all the things I want to - anybody want to donate a decade or two?

EDIT: Oh yeah, I did Stardust's comet too. From images with an ellipsoidal grid overlay and a bit of fudging. I must dig this stuff out.

Here's the Stardust map of Wild-2. The gridded images are based on a paper published a few years ago - can't go looking for it now but easy to find. Longitude is probably arbitrary and I've assumed the visible pole is north.

Thanks for the map but i already have Wild 2
Whats weird is that i cant find a map of these objects especally
Atlas and Pandora because they have been imaged in detail but have no maps.

[Phil Stooke]

For Steins see my note in the Steins thread. You can email me privately about this.

The small satellites of Saturn may not be mapped the way you want them to be until the Cassini mission ends. Peter Thomas, the main worker in this field, has his hands full, and the data sets are still coming in, so a final shape model is not yet available. There's little point working with a bad shape model when a better one will be available soon. I will post my very preliminary Borrelly cylindrical map next week, but I warn you, it isn't pretty.

OK, so here I unveil the first cylindrical projection map of Comet Borrelly - as far as I know, anyway. It's not very good.

First the data source - this image shows a grid superimposed over a visualization of the nucleus. It's from work by Randy Kirk and colleagues at USGS Flagstaff and was shown at LPSC last year. Note that there is no useful published shape model of Borrelly and this must be derived from unpublished work. Those guys are brilliant but the data are very poor so the shape model will be of limited reliability.




I have modified the grid to remove (to fudge over) grid artifacts created where the surface cuts radii more than once (i.e. the surface cannot be represented as a unique set of lat-long-radius points... think of an overhanging cliff on Earth). Here's my version:




Then that underlying image is projected into Simple Cylindrical map space. Because of the extreme irregularity of shape and the fudge factor where the surface 'overhangs', the ends of the nucleus (where most of the interesting topography is found) are compressed and distorted. Future work may allow that to be improved, but I don't have time for it yet.




'north' is chosen arbitrarily.

Thanks for the map
It actually turned out better than i expected.
