I have new images of Venus that I did not announce in these forums.
THe North Pole of the Venus Globe 75x is featured at :
http://www.reliefglobe.com/venus_75x_6deg.html
The resolution is 6 data points per degree of lat/longitude.
The elevations were multiplied by 75.
To see more links to flooded and unflooded Venus see :

By looking at all 4 links on that page, you can look down on
the South Pole, North Pole, and the famous "textured terrain".
The data is combined from Magellan, Mariner, and Venera spacecrafts.
Your colored pictures of a terraformed Venus have been
delightful to look at, repeatedly.
Here is an acknowledgement of the Magellan data source :
The databases for the globes of Venus are from the Magellan Project of NASA. The spacecraft entered an orbit around Venus in 1990. This paragraph acknowledeges the Principal Investigator, Dr. Gordon H. Pettengill, the Astrological Branch of the United States Geological Survey, the Magellan Project, and the Planetary Data System. During 1991 the land height data was published with preparations by Peter G. Ford of the Center for Space Research at the Massachusetts Institute of Technology. One document is called "Altimetric and Radiometric Global Data Records".
Dr. Gordon H. Pettengill first came into prominence for his discovery in 1965 of the unexpected 2/3 spin/orbital period resonance of the planet Mercury, using radar astronomical techniques, although his name is also closely linked to much of the development of radar astronomy since its early years in the late 1950's. Beginning with the first application of coherent earth-based radar to studies of the Moon in 1959, his observations have embraced Mercury, Venus, Mars, several asteroids and comets, the Galilean satellites of Jupiter and the rings of Saturn. He was the Principal Investigator for the Radar Mapper Experiment carried out on the Pioneer Venus Orbiter from 1978 through 1981, providing for the first time a comprehensive view of the global surface of Venus. Since then he has been the Principal (scientific radar) Investigator for the Magellan (Venus-radar-mapping) Mission that was launched in May, 1989, and has since mapped nearly the entire Venus surface at a resolution of a few hundred meters.
Dr. Pettengill received the B.S. in physics from MIT in 1948, and the Ph.D. in physics from U.C., Berkeley, in 1955. Since then he has been affiliated primarily with MIT, first with Lincoln Laboratory and then, from 1970 to 1995, as a Professor in the MIT Dept. of Earth, Atmosphere and Planetary Sciences (from 1984 to 1990, jointly with the MIT Physics Dept.). Leaves of absence enabled him to serve as Associate Director, 1963 - 1965, and as Director, 1968 - 1970, of the Arecibo Observatory in Puerto Rico. From 1984 to 1990, he was Director of the MIT Center for Space Research. Prof. Pettengill retired from MIT in 1995, but has remained active in research since then, primarily with the Mars Orbital Laser Altimeter experiment aboard the Mars Global Surveyor, currently in orbit around that planet.
Dr. Pettengill is a member of both the American and National Academies of Science. In 1980 - 1981, he spent a sabbatical year at the University of Sydney (Australia) as a Guggenheim Foundation Fellow. During the fall of 1991, he was the Thomas Gold Lecturer at Cornell University. In 1994, he was awarded the Magellanic Premium of the American Philosophical Society, and in 1998 he received the Whitten Medal from the American Geophysical Society.
