At feet tall, the giant Dune 7 is believed to be the tallest sand dune in the world. This remote region in western Papua New Guinea contains the Hindenburg Wall, a limestone network of plateaus more than a mile high. The mile-long series of bluffs features nearly undisturbed ecosystems high above the ground. A biological survey of the area found animal and plant species, almost of which were new to science [ PDF ].
Lichen and moss make it a favorite habitat for reindeer. Melting glaciers continue to reveal new islands. Much of the inland part of the country is still uninhabited, as roughly 80 percent of the island is covered by ice cap. This almost foot-tall peak is the largest of a series of mountains that have developed much like separate islands, with very different species making their homes on the different peaks.
In , a group of biologists and rock climbers teamed up to conduct fieldwork in the region, where rock climbing is sometimes the only way to get to unexplored habitats. In , , and respectively. But, all of those expeditions became unsuccessful due to heavy snowfall and unsustainable conditions. So, Gangkhar Puensum mountain became unclimbed and unexplored. It is a known fact that deserts are least explored because of uninhabitable weather conditions. Sahara is the largest desert in the world, depending on unsuitable conditions for growing plants.
Covering over million square miles, Sahara desert located in Africa is the the l argest and hottest desert in the world is Sahara, located in Africa. Deserts only get very little rainfall in a year.
Extreme temperature fluctuations also very common in deserts. The days can be extreme hot. But nights are very cold. It makes very harsh environments for animals, plants and humans. Even though, a few animal and plant life can be found on deserts. Such animals possess high adaptability to live in harsh, desert environment. There are large number of caves located across the world. It is too difficult to explore many caves due to unbearable weather conditions, sharp rocks, scalding water, and slipping conditions in the caves.
Some of the underwater caves in the world are even uninhabited by marine life because of deadliest conditions. The flooded, Yucatan Cenotes cave network in Mexico is the best example for it. The crystal caves and snow caves also become too dangerous for expedition due to unprecedented changes. Covering a total area of 2. The rich biodiversity and presence of many rare species make Amazon rainforest to a focal area for scientific expeditions. There is no dry season in Amazon rainforest, get rain all the year.
The heavy rain in Amazon rain forest between February. It causes drastic rise of water level in Amazon river. It also leads to heavy flooding in Amazon. In such a condition, the transportation through Amazon river also become too dangerous due to extreme river currents.
Users then decide how they want to use it. Nevertheless, even digital maps skew toward the things that their users deem most important. Those areas that the majority sees as unworthy of attention — poor neighbourhoods like the Orangi shanty town in Karachi, Pakistan, or the Neza-Chalco-Itza slum in Mexico city — as well as those places that mapmakers do not often go — war-torn regions, North Korea — remain grossly undermapped. This neglect means maps of remote regions can contain errors that go unnoticed for years.
Scientists paying a visit to Sandy Island , a speck of land in the Coral Sea near New Caledonia, recently discovered that the island simply did not exist. Google has two approaches to addressing these problems: sending mapmakers out into the wilderness with Street View cameras attached to backpacks, bikes, boats or snowmobiles, and launching Map Maker , a tool created in that allows anyone anywhere to enhance existing Google maps. Favelas may be close to well-known cities, but they are not well-mapped Thinkstock.
But while many communities have literally put themselves on the map, others have not. Traditional paper maps tend to neglect these areas as well.
In recognition of this problem, a new effort called the Missing Maps Project — organised by the Red Cross, Doctors Without Borders and the Humanitarian OpenStreetMap Team — recruits volunteers to fill in the cartographical blanks in the developing world. Coastlines often change faster than maps can track them Getty Images. The ocean, likewise, is one of the most poorly mapped areas of the planet, despite the fact that it occupies the most space.
In light of increasing interest in underwater mining and drilling, certain countries — especially Russia — are looking to lay claim on large tracts of ocean floor. Additionally, with sea ice quickly receding, more and more territory will come up for grabs. To draw attention to this gap of knowledge, Brotton and artist Adam Lowe are creating a 3D map of the ocean floor without water.
For others, though, untold stories abound even in some of the most prolifically mapped places in the world. Dave Imus , an award-winning mapmaker based in Oregon, acknowledges that much of the world has been mapped in a basic sense, but believes that the vast majority of maps are not good enough.
