I've just published my new topographic map of Mars in Mercator and polar stereographic projections.
Basic info is directly in the map.
Map is available as 17 400 14 700 pix 78 MB jpeg via Flickr and as PDF with searchable text via Google Disc (106 MB!).
As always for big PDFs, I recommend Sumatra viewer.
Some other infos are on my blog but it's in Czech language.

Very impressive work. And Google translate apparently does a relatively good job translating the Czech text into English - I think I was able to understand/interpret all of translated text.

Google translate is very good for some languages in case of translating them to English and Czech is one of them ( I think smile.gif ).

New version of my topographic map of Mars is now available.
This "Easter egg" version has high resolution (~ 100 m/pix) parts around most of the landing sites.
It works only as PDF so only this version is available. It has 116 MB and it needs good PDF viewer and
computer with enough power (tested with Sumatra, FOXIT, SMART viewer and 8GB RAM).

For an example here is part around Mars 3 landing site (located via HiView, longitude 202.01934056, latitude 45.0445105).

EDIT: Files are now with correct English abbreviation for Soviet Union.

Dear Machi, thanks so much !!!!
Could you, please, be so kind to provide us also with the Mars 3 lander elevation ?
Thanks so much in advance and with warmest regards,
VM

You're welcome!
Closest measurement from MOLA gives 1626 meters, HRSC DEM with better coverage but with lower precision gives ~1660 meters.
Best guess based on published data 1655+/-30 meters. I suppose that I will add elevations for every identified lander in future version of the map.
BTW, according to HiView coordinates of Beagle 2 are 90.4303226,11.5270253. These are slightly different than values which Doug Ellison extracted from Google Earth (90.4295E 11.5265N). This very small difference gives location error ~500 meters. But I have no idea how precise HiView is but based on my experience with other landers I suppose
that Google is worse than HiView.

I pulled my values from HiView also...which is worrying.

From which image? I've used ESP_037145_1915.
I tried to extract location again in full resolution and it gives me 90.43036115568,11.52698736394 or 90.43036543916,11.52698314553.
And I used wrong number in calculation so it's not error ~500 meters but only 50 meters. That's relatively negligible error.

My apology, as in previous version, I forgot Czech abbreviation of the Soviet Union in the map.
Now links leads to version with correct English abbreviation.
And I've added small new feature - the map has hidden word "outpost" which facilitates the searching for landing sites.

Updated version of my map with all official names up to date 14.1.2016.
Full resolution image has ~110MB and PDF has 117MB.
BTW, lowest place on Mars has finally official name - crater Badwater.

Interesting to match Machi's stunning topographical map with the just completed Gravity and crustal thickness maps.
