In theoretical, this article discusses the feasibility of integrating the geographic data supplied by geographic information system and remotely sensed data. In methodically, it discusses how the ≥10℃ accumulated temperature, terrain elevation and annual rainfall, which were considered as three key factors to reflect the local climatic resource conditions, can be digitized according to a certain ground grid system, then integrated it with the LANDSAT TM data. In application, it takes the natural environment of Changbai County, which located in southern slope of Changbai Mountains, as working area and makes mountainous climatic resource study. The research results show that the research method changes the single spectrum information structure of LANDSAT remotely sensed data set; it realized the digital transmission and image display of geographic data; enriched the image information. In the climatic study, the quantitative boundary of different classes were realized and the accuracy of classifications were greatly improved.
