I search Altimetry Profiles Titan. Where their possible find?

You're right -- but I'm pleased to say that you posted bootleg versions not just of Outbound Ta, but of both Inbound and Outbound T3. You naughty boy. They're awfully fuzzy, but at least we've got them:

In fact, R.L. Kirk and Charles Elachi both say that the only altimetry profile returned from Ta was the Outbound one. That's the only one which has been officially released yet (and it does match your bootlegged copy of that one):

As for the two altimetry profiles returned from the T8 pass, Elachi says: "Rudimentary threshold processing of the T8 altimetry indicates modest regional slopes and no major topographic features in the ~300 km-long swaths. More sophisticated processing to account for off-nadir pointing and the use of reconstructed ephemeredes is needed for more robust conclusions." ( http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1252.pdf )

Finally, there are several interesting LPSC abstracts on the use of clinometric techniques to try to calculate topography (although Jason himself has expressed doubts about the use of this, at least on optical and near-IR wavelengths, given both the haze-fuzziness and our uncertaintities about local albedo variations on the surface). These include Kirk's abstract, and also:

And we have the analysis of the startlingly rugged topography at the Huygens landing site from stereo DISR images: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/2089.pdf . (Note that the extremely nice color-coded 3-D topographic map is described as having "no vertical exaggeration", with the italics being theirs. Steep local slopes produced by liquid runoff erosion seem to be one of the biggest threats confronting future Titan landers.)
