南極洲談不上是最熱門的旅游目的地，但對探訪南極的人來說，目前科學(xué)家們可以提供這片凍原的令人難以置信的高分辨率地圖。

據(jù)Earther網(wǎng)站的報道，南極參照視圖模型（REMA）的構(gòu)建使用了幾十萬幅拍攝于2009至2017年間的衛(wèi)星照片。隨時間推移這片土地的海拔等大量數(shù)據(jù)容納于一臺超級計算機，隨后創(chuàng)建了REMA，這是極為詳細的地形圖，文件尺寸超過150TB。

一份俄亥俄州的新聞稿指，這份新地圖的分辨率達到2至8米，而一般地圖的分辨率為1000米。另據(jù)《紐約時報》（The New York Times）報道，新地圖顯示細節(jié)的程度，相當(dāng)于你可以看清地圖上的一輛汽車，甚至更小，而以前你只能看到完整的中央公園。科學(xué)家已經(jīng)掌握了南極每一處的視圖，誤差范圍僅幾英尺。

新超高清地圖事無巨細地展示南極洲。

REMA項目的負責(zé)人、俄亥俄州立大學(xué)冰川學(xué)家伊恩·豪厄特在一份新聞稿中說：“目前為止，只有火星地圖比南極地圖要強一些，在這種分辨率下，可以看到任何東西。我們甚至能看到一些地方雪量的變化。我們可以測量這塊陸地表面隨著時間推移的各種變化。”

這份地圖將成為各研究項目所需的至關(guān)重要的工具，它可以提供雪量、冰層活動、冰山融化、河流和火山活動等各類數(shù)據(jù)。科學(xué)家可以更好地監(jiān)控氣候變化帶來的影響，而研究者也可以更方便地安排實地考察。（財富中文網(wǎng)）

Antarctica might not be the hottest tourist destination, but for anyone who does visit, scientists now have an incredibly high-resolution map of the white tundra. According to the scientists at Ohio State University and the University of Minnesota who created the imagery, Antarctica is now the best-mapped continent on Earth.

The Reference Elevation Model of Antarctica (REMA) was constructed using hundreds of thousands of satellite images taken between 2009 and 2017, Earther reports. A supercomputer assembled the massive amounts of data, including the elevation of the land over time, and created REMA, an immensely detailed topographical map, with a file size over 150 terabytes.

The new map has a resolution of 2 to 8 meters, compared to the usual 1,000 meters, says an Ohio State press release. According to The New York Times, the detail of this new map is the equivalent of being able to see down to a car, or smaller, when before you could only see the whole of Central Park. Scientists now know the elevation of every point of Antarctica, with an error margin of just a few feet.

“Up until now, we’ve had a better map of Mars than we’ve had of Antarctica,” said Ohio State University glaciologist Ian Howat, head of the REMA project, in a press release. “At this resolution, you can see almost everything. We can actually see variations in the snow in some places. We will be able to measure changes in the surface of the continent over time.”

The map will be a vital instrument for research projects, providing data on snow cover, the motion of ice, thinning glaciers, and river and volcano activity. Scientists will better be able to monitor the effects of climate change, and it’ll be easier for researchers to plan field expeditions.
