| Resumo | Technological advancements have favored geospatial analysis and Remote Sensing applications, allowing more detailed target characteristics evaluation and reduced information loss. Simultaneous imaging of the same scene in multiple bands of the electromagnetic spectrum became possible, thanks to multispectral and hyperspectral sensors. Also, it is possible to extract directly from an image a reflectance spectrum closer to that which could be obtained in laboratory. Sensors like OLI on Landsat 8 (with 8 spectral bands) and ASTER on Terra satellite (with 14 spectral bands) are important for multispectral observation due to their narrower spectral ranges. Despite having only 5 spectral bands, REIS sensor on RapidEye satellite has shown improvements in spatial, temporal, and radiometric resolutions. Although geological targets are closely linked to soils spectral response, which is influenced by several natural factors, some minerals spectral response overlaps soil response, making possible to identify this behavior through remote data analysis obtained by high spectral resolution sensors. This research aimed to compare three minerals classes spectral response (oxides, silicates, and carbonates) using both laboratory spectroscopy and spectral resampling based on the response functions of four satellite sensors (MSS5 Landsat 5, REIS RapidEye, OLI Landsat8 and ASTER Terra). The minerals spectral data analyzed (hematite, goethite, olivine, topaz, rhodochrosite and siderite) were acquired at United States Geological Survey (USGS) digital spectral library and resampled using ENVI. Satellite response functions (SRF) were acquired and plotted over these resampled spectral curves to analyze remote sensors technology advances influence and its implications facing spectral resolution refinement. Results indicated an overall information gain captured by satellites as the sensors technologically advanced. However, compared to laboratory spectroscopy, there was an information loss due to the sensors greater spectral sensitivity. Nonetheless, by integrating shorter, adjacent spectral bands, sensors could overcome limitations in representing Earths surface targets. The evolution from MSS5 to ASTER sensors particularly showed increased information capture, with contributions extending beyond spectral resolution, including reducing temporal resolution, refining spatial resolution, and increasing the gray levels quantization capacity in remote images. | |||
