Everyone knows that polar bears are carnivores，But why doesn’t it eat penguins？Jing Ke assassinates King Qin，Why are you offering "See you with a dagger in the picture"，Instead of offering gold, silver and jewelry？If you want to take a flight from Wuhan to the United States，Does the plane cross the Pacific Ocean directly?？Aren’t these questions interesting?？Although these problems seem varied，But they are all related to an important element，That’s the map，Map can help us understand the world，Map can also change the world。November 3, 2021，Our school invited dafabet sports betting websiteprofessors from the School of Resources and Environment of Wuhan University、Doctoral supervisor Ying Shen，Introducing the importance of maps to us。
Professor Ying Shen is part of the national high-level talent program、Leading talents of the Ministry of Natural Resources；Deputy Director of the Department of Geographic Information and Map Science, School of Resources and Environmental Sciences, Wuhan University。Presiding 4 National Natural Science Foundation projects，Presiding 1 Hubei Provincial Natural Science Foundation Outstanding Youth Fund，Won 5 national, provincial and ministerial level awards including the First Prize for Surveying and Mapping Science and Technology Progress Award in 2019；Published more than 100 papers。Main research fields are cartography and visualization、3DGIS and three-dimensional cadastral、Spatial analysis and geographical big data。Professor Ying Shen’s opening，Quotes a famous saying: How far is the thought，How far can one go，But in fact，How far is the field of view，How far can a person go，For example, Li Bai, the most famous poet in ancient my country，Many of his works were inspired by his experiences while traveling around the great rivers and mountains of the motherland。According to statistics，Li Bai visited 97 cities in his life，Traveled 35851 kilometers，Write 1015 poems。Another example，Ptolemy active in Alexandria in the 2nd century AD，He is a person with a strong thirst for knowledge，In Astronomy、Astrology、Mathematics、Geography、Making achievements in music and other fields。Ptolemy described the locations of continents and oceans on a spherical Earth，And the location relationship of each region，Draw a bird's eye view of Morocco in the west with equally spaced longitude and latitude lines、A vast area east to China。He gave mankind an overall "world" understanding of the earth，Its view of the world is ahead of all maps drawn by any country，Also influenced the world’s navigation activities，He also deserves to be the father of the world map。
Many turning points in the history of world development、Events that changed the development of the world，It’s all about the map。So what can maps be used for?？Map has many functions dafabet best online casinoand images for us。For example, big data analysis，Now our mobile phone positioning、Sky Eye System, etc.，By locating people、Action trajectory analysis，Big data robots can quickly identify a person’s life trajectory and whereabouts。It can also help many businesses conduct site selection analysis，For example, McDonald’s and KFC，Always appear in an area within a radius of no more than 1 kilometer at the same time。This is just what maps mean to our lives，Map has an important meaning far beyond navigation in life。
Why did Jing Ke assassinate the King of Qin，What was presented to King Qin was a map？This is the national significance of the map。2014，The General Secretary raised the "map question" at the 17th Academician Conference of the Chinese Academy of Sciences: the map of China drawn by missionaries in 1708 by the Qing government，Why as a collection house, it has no effect on economic and social development，These missionaries brought the information back to the West and compiled and published it，But it has enabled Western countries to understand our country’s geography better than we do for a long time？Territorial Map，It is of great significance to the country。Why the South China Sea belongs to China？The location map of the South China Sea drawn by the Republic of China in 1947，Clearly stated Dongsha、Xisha、Zhongsha and Nansha，and has a U-shaped line。via map，You can also establish a correct worldview。If you look at the China-US route from a globe，From China to the United States，The shortest connection is across the Pacific Ocean，But flying from China to the East and West Coast of the United States，No route is directly across the Pacific。In the world view expressed by the map，The expression "center of the world" is very interesting，The perspective of the center of the world，The expression is different in every era and every country and region。For example, the 1937 "Commonwealth: The British Empire" version of the world map，The center is Britain；American version of the modern world map，Just like my country’s modern world map，The perspective is completely different；Australian version of world map，It is completely opposite to the map of the Northern Hemisphere；dafabet online sports betting appUnited Nations LOGO world map，centered on the North Pole，Expresses the idea of national equality。In addition to the horizontal world map expression we often see，Chinese scientists also drew a vertical map of the world，The military significance of maps、Strategic significance is also crucial to our country。Map can be used to express opinions and situations，For example, we often say "all roads lead to Rome"，This was the Roman Empire that was very prosperous at that time，This pattern is real。Another example is the famous Hu Huanyong Line。Hu Line，or Heihe-Tengchong Line，or Aihui-Tengchong Line)，That is, the contrast line for dividing my country’s population density proposed by Chinese geographer Hu Huanyong (1901-1998) in 1935，This line starts from Aihui, Heilongjiang Province (renamed Aihui in 1956)，Renamed Heihe City in 1983) to Tengchong, Yunnan Province，Roughly a basic straight line inclined at 45 degrees。The 36% of the land southeast of the line is home to 96% of the population (according to the fifth national census data in 2000，Accurate calculations using ArcGIS show，The southeast half calculated based on the Hu Huanyong Line accounts for 43% of the country’s land area.8%、Total population 94.1%），With plain、Water Network、Hills、Karst and Danxia landforms are the main geographical structures，Farming has been the economic basis since ancient times；The population density in the northwest of the line is extremely low，It’s grassland、A world of deserts and snowy plateaus，The world of nomadic people since ancient times。Thus demarcating two completely different natural and cultural regions。
With the development of technology，The map also consists of the original flat map、The image map developed to the present、Surface model、Vector map、3D map、Holographic Map、Live map、Augmented reality maps and more。Map has changed our daily life，Travel、Catering、Entertainment、Business and other activities，The first thing we do when driving is probably to turn on the mobile phone navigation system，Go on a date、Dating、Dinner、Travel, etc.，Wuhan University’s surveying and mapping science and technology is the world’s number dafabet online sports betting appone surveying and mapping major，Teacher Ying Shen’s humor and wisdom made the students very interested in this major。
