3D structure change detection

3D Structure Change Detection is a type of Change detection processes for GIS. It is a process that measures how the volume of a particular area have changed between two or more time periods. A high-spatial resolution Digital elevation model that provides accurate 4-d structural information over area of interest is required to compute such changes. In production, two or more DEMs that cover the same area are used to monitor topographic changes of area. By comparing the DEMs made at different times, structure of terrain changes can be realized by the ground elevation difference from DEMs. D ...

84th parallel north

The 84th parallel north is a circle of latitude that is 84 degrees north of the Earths equatorial plane, in the Arctic. It passes solely through the Arctic Ocean. The northernmost land on earth, Kaffeklubben Island, Greenland is roughly 40 kilometres south of this parallel. At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and astronomical twilight during the winter solstice.

American Cordillera

The American Cordillera is a chain of mountain ranges that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, South America and Central America. It is also the backbone of the volcanic arc that forms the eastern half of the Pacific Ring of Fire. From north to south, this sequence of overlapping and parallel ranges begins with the Alaska Range and the Brooks Range in Alaska and runs through the Yukon into British Columbia. The main belt of the Rocky Mountains along with the parallel Columbia Mountains and Coast Ranges of mountains ...

Angamuco

Angamuco is the name given to a major urban settlement of the Purepecha civilization, now in ruins hidden under vegetation, in the Lake Patzcuaro Basin of Michoacan, Mexico, and discovered in 2007. In 2012, using LiDAR technology, archaeologist Christopher Fisher and team detected an estimated 39.000 buildings at the site, roughly the same as Manhattan, on a territory of approximately 25 square kilometres. Fisher believes the settlement was founded around 900 CE and reached peak importance from around 1000 to around 1350 CE with a population of over 100.000 – making it the most populous ci ...

Australian Geographer

Australian Geographer is a quarterly peer-reviewed academic journal published by the Geographical Society of New South Wales since August 1928. Covering all aspects of Australian geography, it is currently copublished with Taylor & Francis.

Autonomous province

Autonomous province is a term for a type of province that has administrative autonomy. In political history, the term has been used as designation for various types of autonomous entities, on medium levels of administrative hierarchy. In relative terms, an autonomous province usually has less autonomy then an autonomous state, but more autonomy then an autonomous region. Administrative autonomy of a province can be expressed in its official name, by the use of a particular term designating the autonomy, but such term can also be omitted. In that case, the autonomous status of a province ca ...
