By using the light control image code method and system
Provide a method and a system for controlling light by using an image code. The method comprising: displaying on a display unit an image code; obtain information on light provided by the image identification code; and a light emitting means status information is determined by using information about the light provided; and the apparatus has the image information of code the same device information light emitting means for transmitting a request message according to the light emitting state of the light request setting information.
In the past 19 years,while China's urbanization was fast-developing,a series of problems related to urbanization were there upon production.In this paper,based on spectrum characteristic of knowledge method,the thematic information of three periods of LUCC were extracted from Landsat TM,ETM + and CBERS-2.Combing with the GIS technology,the land-use transfer matrix from 1987 to 2006 were obtained.Besides,the LUCC models were applied to analyze the characteristic of land use change from 1987 to 2006.Based on the land-use change map and land-use transfer matrix,spatial dynamic characteristic and land-use conversion of the study area were analyzed.The research could provide suggestions for land management and making policy for local government.
