Here is a map of Venus I had put together (recall this collaboration with Emily L. and Calvin Hamilton), with the feature names now added.

Using a shaded relief map we get another view. Might be better with a different feature color though:

Yes, that would be nice to take a look at your higher resolution map. I recall that the data Emily had given me was intrinsically at a higher resolution than what I have used so far.
The features at present are plotted only if larger than 750-1500km, depending on feature type. These thresholds can be experimented with if one wants more names of smaller features. I also posted a transparent PNG file, so the feature overlay can be added to any map: http://laps.noaa.gov/albers/sos/features/overlay -------------------- Steve [ my home page and planetary maps page ]

here is a link to a 16384x8192 pgm
82.0 MB (86031088 bytes) -- yes there is advertising -- http://www.zshare.net/download/9916352888d55b30/ it is a reduced down to 45.51 ppd from the 469.4485 ppd of the C1 |

I just finished my biggest work ever - topographic map of Venus.
Basic map description is directly in the map. For now, it's available only in reduced (50% of original size) and splitted jpg versions (61% and 80% of original size), mainly due to Picassa size limitations. If someone wants full PDF version of the map (~100 MB), send me a message (via UMSF message system or email). I will be glad for any constructive criticism and informations about errors. -------------------- |

Stunning, Daniel!

Yes, that is superb.

machi
what did you use as the base imaging data the c3 compressed data it looks like you also removes the ~+7 degree offset vertical stripping i had fun with that using the c1 data ,as you get closer to the poles the angle gets closer to +- 90 deg. google translated the blog and answered the question |

Dan, Nick, Phil, Ted
Thanks! John: I used left-, right-, and stereo-look maps from Map-a-Planet. It was hard task for this application, because it lasted 5 - 10 days for the M-a-P to complete these maps. In near future I want to look on other datasets and fill some gaps. Some data I have already on disk and it looks promisingly. -------------------- |

there is a lot of missing data
the low resolution height data is missing a lot near the poles http://pds-geosciences.wustl.edu/mgn/mgn-v...1/mg_3002/gtdr/ and the "f" and "c1,c2,c3" reduced size data from the -- the c1 i used http://pds-imaging.jpl.nasa.gov/data/mgn-v...5-midr-c1-v1.0/ with the pole archive http://pds-imaging.jpl.nasa.gov/data/mgn-v...r-v1.0/mg_0127/ but i am also using ISIS3 for that data as for the "gaps" i had it "inpaint" them most of the missing data is near the poles so in a top down "polarstereographic" i used "resynthesizer" mostly to fill in the areas a bit of code i have been using for years , since before it became a gimp plugin . a screen shot of the southpole ( aprox -45 to -90 ) -- -180/180 is in the bottom middle |

"there is a lot of missing data"
Yes, some gaps cannot be filled with real data (topography, BTW I worked with MG_3003, MG_3002 is obsolete) and in some cases it's possible. I found dataset mg_0127 after I have all maps done, so this data will be incorporated in next version. Also this version has polar stereographic projections made with G.Projector, very good program, but limited in resolution (max. output 7500×3750). For next version I want to use higher resolution data resampled to native map resolution. It looks better. And I don't want to fill bigger gaps for which real data doesn't exists simply because this map must display our current coverage of the surface of Venus. But thank you for your info about "resynthesizer", I didn't know that. -------------------- |
