Geo-information technology is a complex applied technology mainly consisting of remote sensing, geographic information system and global positioning system, which is gradually becoming the important part of the information technology and the key competition point of all countries in information field. The technologies of global positioning system, remote sensing and geographic information system are discussed. Their integrative applications in natural disaster monitor and management, resources investigation and monitor, and fine farming are also discussed.

The potential energy functions and spectrum constants of VFn±(n=0,1,2) have been analyzed by the density functional method(B3LYP/6-311++g(d,p)).The results show that all of them can exist stably.Their ground electronic states are 5Π(VF),4Σ(VF+),4Σ(VF-),3Σ(VF2+) and 5Σ(VF2-).Among them,the potential energy curves of VF2± have the form of a volcanic crater.The molecules of VF2± are in meta-stable states.All potential energy curves have been fitted with the eight-parameter Murrell-Sorbie functions.It has been found that the fitting curves of the meta-stable ions VF2± are well in accordance with their potential energy curves.However,the four-parameter Murrell-Sorbie functions are not suitable for VF2±.At the same time,the effect of charge on the potential energy functions and energy levels have also been discussed.
