The information turns, the network turns, the arithmetic figure turns, the wave tide that intelligence turn is dashing and crashing, the arithmetic figure city is exactly the tide a stride over type for, if our country can holding tight history giving develop -ment opportunity of this wave tide, Chinese city planning, developments with mana - ge the level may wash into the ex- row of the advanced countries of world the pole, an -d arouse the development of the related industry.A,GIS development historyPut forward first from 1962 Canadas rogertomlinson the concept of the geography information system combines to leads to establish in the world the first has the practi -ceal worth a geography information system Canada geography information s -ince system( canada geographic information system, brief name cgis), geography information the system acquired the substantial advance within the scope of world. the conduct and actions turns to describe to the living spatial arithmetic figure in mankind, analysis with expression of tool, gis an importance that become the information industry gradually constitutes the part, becoming the national economy to increase to order newly. be engaged in the theories of gis inside the world scope with the application study of development personnel, section a main melody for with high and new business enterprise countlessly, applied sciences turning, science technique turning, techniIque industry turning already becoming the realm of gis developping. geography information system at from a pure and applied system the development is a complete technique system with theories system.The gis( geography information system) development is from 1965 of, at that time Harvard a land measures the professional student to mention like this a viewpoint in graduation thesis:Can measures the data system and geography the fusion is together. Hence, he designed a the most simple the system of gis, and established the company of esri after graduating.It is the company of the biggest the system of gis of world now.Development that through several decades, the system of gis has been turned into by an application for learning realm for with service a foundation type for learning realm application as main purpose terrace software, then serve the company use to transact realm is main purpose that tables top type terrace software that am/ fm/ gis( automated mapping/ facilities management/ geographic information system) sy -stem with then serve in the city public facilities management is the main purpose waits several branches.The gis is not only applied in the geography, geology.etc. pr -ofession realm, it is current to all there is extensive application in the each realm, such as water conservancy, electric power, petroleum, transportation, telecomunicati- on, public security official, environmental protection.etc.Come up to say from the concept, the geography information is the gross of the arithmetic figure to point the elemental quantity, quantity, kind in environment in ge -ography in enunciation and distribute the characteristic, contact to wait with the regu -lation, writing, picture, sketch.etc. information to call.Pass the geography informat- ion technique, collect relevant the Earth every bit and all informations, tidy up the da -ta that process easy to usage, and press permafrost geography to sit the mark deposit, needing deliver the homologous place immediately, and here the foundation is last, as to its proceed to process, tidy up, for the analysis of various applied realm, manage, the decision offering is more the basis of science.See from the system angle, in future and severally 10-yearl
