Map of Eros Options

[Phil Stooke]

Here's a bit of something I have been working on for the last few months. I am making a high resolution photomosaic of 433 Eros. It will eventually go in the Planetary Data System.

This square image is part of the mosaic, hot off the press. It extends from approximately 60 north to 60 south, and 240 west longitude (right edge) to 360 (AKA 0) at the left edge. The original is 5000 pixels square. The projection is Simple Cylindrical. When finished the original will be 14400 by 7200 pixels.

I leave on Monday for a couple of weeks in the UK. When I get back I'll post a version of this with a grid, and the two polar sections I have also done.

I should add that in areas where this appears distorted (lower left region), this is caused by the extreme irregularity of Eros in this region.

Excellent work, Phil! I am more and more impressed with your abilities.

I second that - marvellous job!
Enjoy your time in the UK Phil - the sun's shining as I type.....

Could you also add the landing point ?
Thanks Phil

Phil...

beautiful.....

looking at this I am tempted to caption it "The Gravel Runs Through It".

Just time to post this before leaving... complete consistency in lighting is not possible at the poles.

Here is the new Eros section with a labelled grid.

Phil, you're our (H)ero(s)

I thought that image looked familiar. Finally put my finger on it.

Wow...that is really incredible. Also, the Scream resemblance is uncanny!

Phil,

Do I hear correctly that you are now working on a high res photo-mosaic of Eros? What sort of projection are you planning to use? The square grid one does make it hard to visualise the "banana-shaped" object.

It would be good to get some place names on there as without The Saddle and whatever else indicated it's hard to relate such a weird angular place to the spectacular photos we saw a few years back.

And weren't you going to add the landing spot of NEAR?

Keep up the great work

Hi Kenny!

Yes, I'm working on the map. One third of the whole thing is posted above. I have nearly finished the second third now. It's a very slow process.

As I have said to others elsewhere, the square grid version - a simple (or equidistant) cylindrical projection) is the most useful format for compiling a global image database, because pixel location translates directly to latitude and longitude. Other representations, including images draped over 3D shape models for dynamic display, are better for many reasons... but where do you get the global mosaic to drape over the shape if some poor slob hasn't devoted a year of his life to compiling it?

So I'll do the hard bit - making a global mosaic. It will go into PDS for everybody to use, and I'll post reduced versions here. But I'll let others do the 3D versions, the animations, the annotated versions etc.

Here's a version with the approximate landing site added, taken from the NEAR website illustration linked to above.

Here's a superb scale model of Eros:
