nautical cartography

the theory and technology of ancient Chinese cartography have reached a considerable level. A.D. Third century, China's Peixiu compiled the "Gong area Map" and "topographic abbot map", put forward the "cartography six Body", which is the most incisive exposition of the principle of mapping in ancient China, the formation of the Eastern unique map technology, in China has also affected the last thousand yea

???? Using GIS technology for cartographic mapping, the ultimate goal is to return to the cartography. The following are some of the classic requirements for map making in cartography:Maps must conform to reality, to human perception.???? This is the most basic of the map, each element of the map is shown with the actual entity corresponding, although sometimes in order to highlight the characteristics of the geographical features and moderate exagger

Self-accomplishment of GIS mapping staff (2)--Cartographic consciousness by Li Yuanxiang The last mention of some cartographic errors of GIS mapping personnel, mainly for the GIS cartographic staff to analyze some of the problems in the cartographic work. But how to improve the self-cultivation of cartography, but it is a very long process, this chapter mainly for the promotion of cartographic cultivation to make some theoretical groundwork. One of th

features, you can also see the representation rules and effects under the toolbar.Under this interface, you can use both the free editing tool and the representation's rules and geometric effects tools. Cartography is a job that requires imagination, and when we see the elements of this ellipse, we should be able to relate to the real stadium. At least the first time you can think of drawing with abstract simple strokes. Therefore,

World Meteorological Organization, they are all based on the generalized "distributed model ". Therefore, we acknowledge the spatial and temporal distribution of geographic data, and use the Cognitive View of distributed information to consider and process geographic information, and apply this cognitive view to the mathematical and physical tools used by humans, is the most feasible method. InFrom the perspective of cognition, although humans can perceive geographical phenomena through cogn

Mathematics Institute? The answer is self-evident, but why can no one stand up and shout "stop "? Previously, it was said that GIS in China is "platform and department fly together". Although this is not good, it is always several times better than the current "Research and metaphysics. Although the former is not good, although it wastes the joint property of the majority of working people, it can create MapGIS and Supermap, which can make the market share of domestic GIS software more than 1
