Abstract: In 21st century, humankind is facing the information society (IS) and sustainable development(SD). It means that we are in a Coordination Development System of Man and Earth society which is an open, complex, nonlinear, dynamics and super-system. This paper discusses outer space information and geographic information network system and their application to the sustainable development information society. There are three parts in it which are as follows: (1) Outer space and geographic information network systems. The outer space information is including Remote Sensing Systems(RSS), Data Collected Systems(DCS), Position Satellites Systems(PSS), and Satellites Communication Systems(SCS). The grographic information is including Geographical Information System(GIS), Geographical Expert System(GES), Management Information System(MIS), and Decision Support System(DSS). The network system is as shown in figure 1. There are 4 levels which are technicians, experts, managers and decision makers levels in the network system. (2) Information society of sustainable development strategy. The population is growing up more and more in the world, nowadays it is more than 5.84 billions(1997). But the earth could not be increased. There is about 0.148 billions sq km land on the earth surface. It is about 40 persons/sq.km on average. On the earth surface the land, resources and environment are all limited quantity. Human is facing non sustainable development. The Man and the Earth System(MES) is an interweaving system of humansphere(society) and an earthsphere(nature) subsystems. Both subsystems have input and output to and from each other. There are 5 limited conditions to the input and output for both humansphere and earthsphere. See formulae (2)-(6). Author has advanced the Coordination Development System of Man and Earth. Using outer space information and geographic information network systems could be monitoring and controlling the Man and Earth System. (3) Infomation models for coordination development system of man and earth. There are many kinds of information models in the outer space and geographic information network systems. At least there are 4 kinds: such as remote sensing information models(RSIMs), geographic information ceded models(GICMs), management information models(MIMs), and decision support information models(DSIMs).
