Africa on the world map: What's the real size?

But, in reality, three Canadas would comfortably fit inside Africa. Our world map is wildly misleading. It's all down to the European cartographer Geert de Kremer, better known as Mercator, and his 16th century map projection. While a convenient way to chart the world, the map distorts the true size of countries. "Somehow this map projection came to be used on most world maps, especially those produced for classrooms since the beginning of the 1900s," says Menno-Jan Kraak, president of the International Cartographic Association and professor of cartography at the University of Twente, Netherlands.

"Most of us have grown up with this world image. " Made for captains Mercator initially made globes. Mercator's solution was to stretch out the northern and southern extremities of the globe to fill those gaps, producing an elegant and usable map. A political tool? ESRI-Education. Interpreting "Earth at Night" Images. Students Map Real-World Issues with (Free) Geospatial Tools. Imagine being an emergency responder in a small town that hasn't mapped its fire hydrants, labeled rural roads with street signs, or identified evacuation points in the event of natural disaster.

Students Map Real-World Issues with (Free) Geospatial Tools

Now imagine being part of a high school team that addresses those issues by thinking critically and using sophisticated geospatial tools to communicate findings. Until recently, only a small number of schools have had access to the high-powered geographical information system (GIS) software that enables detailed, layered mapping and analysis of data. Thanks to a recent $1 billion pledge from software developer Esri, free access to cloud-based mapping software is coming to 100,000 K-12 schools across the country.

The donation of ArcGIS Online, the same software that governments and businesses use, has been pledged through ConnectED, a White House initiative to improve education in the STEM fields. Animaps.

Mount McKinley Elevation Survey Results Coming Soon (7/23/2015 9:30:00 AM) A team of four climbers has recently returned from the highest point in North America with new survey data to determine a more precise summit height of Mount McKinley.

Mount McKinley Elevation Survey Results Coming Soon (7/23/2015 9:30:00 AM)

It is anticipated the new elevation finding will be announced in late August. The ability to establish a much more accurate height has grown with advances in surveying technologies since 1953 when the last official survey of Mount McKinley was recorded. The new elevation will eventually replace the formerly accepted elevation of 20,320 feet. ”Determining an updated elevation for the summit of Mount McKinley presents extraordinary challenges,” said Suzette Kimball, acting director of the USGS. “The USGS and its partners are using the best available modern GPS survey equipment and techniques to ensure the new elevation will be determined with a high level of accuracy and confidence.” 38 maps that explain the global economy.
