The use of remote sensing for environmental studies has contributed significantly to several analysis related to the planning and management of natural resources, as both became possible mainly due to the periodicity and quality of the images provided. According to the needs of each survey, its necessary, to have images with different resolutions to better get information. Thus, the satellite images with high spatial resolution provide important information, besides the best work schedules, however they present a high cost of acquisition. Still, the panchromatic image fusion with multispectral images, is a viable alternative. In this context, this article aims to perform the merger of images from the CBERS 2B Satellite (CCD sensor and HRC), using the IHS method, in order to update data of topographical maps and lower resolution images. The chosen area for the completion of the merger was João Dias Creek basin, located in the municipality of Aquidauana/MS with an area of 11.665 hectares. As a result we obtained a fused image with a resolution of 2,7 meters and it was possible to notice a considerable improvement compared to the spectral resolution that was preserved from the CCD image and gains relative to the spatial resolution of the HRC image that was incorporated, allowing a better definition and distinction of the different targets presented in the images. From the image of the topographic map data, as well as images of lower resolution became possible, favoring the achievement of information that assist in the planning of urban and rural areas.Pages: 7434-744
