Hyperspectral remote sensing technology obtains hundreds of narrow spectral bands in the visible, near-infrared, mid-infrared and far-infrared bands and contains a wealth of space, radiation and spectral information. Much materials can be identified that are not recognized in multispectral data. The recent advances in broad width hyperspectral imager, space-borne hyperspectral data digital simulation, calibration and processing and typical applications in the investigation of mineral and oil-gas resources are introduced in the paper. In additon, the information system of hyperspectral data acquisition, storage, management, typical geological application and distribution is established, which shall be of great significance to the application of hyperspectral remote sensing data to the investigation of mineral and energy resources. ©, 2015, China University of Geosciences.

Hyperspectral remote sensing technology is new in oil and gas exploration. Based on the theory of abnormal surface symbiosis with oil and gas microseepage, four typical classifications, maximum likelihood classification in the wavelet-based principal component analysis, endmember extraction, typical alteration classification with spectral libraries and decision tree classification based on vegetation indices are chosen to carry a case study of Hyperion images in Yulin, to obtain the related thematic maps such as clay, carbonate, vegetation and determine six comprehensive anomalous areas. A comprehensive analysis of the distribution of existing gas well and oil-gas anomalous areas show that the information extraction method of oil and gas microseepage is valid. ©, 2015, China University of Geosciences.

In order to verify the anomalies without any field survey data in remote sensing image caused by hydrocarbon micro seepage phenomenon, the multispectral image and hyperspectral image anomaly interpretation results are used to verify each other in this paper. A new method to confirm the multispectral principal component aberrant threshold value by counting the multispectral pixel value located in the hyperspectral anomaly area is proposed. The overlap rate between the multispectral image anomalies divided by the new method and the hyperspectral image anomay area is computed at 98.808%, higher than the traditional principal component threshold technology. ©, 2015, China University of Geosciences.

Enjoying great advantage in accurate classification of ground objects, hyperspectral imaging technology has become popular in geological remote sensing. To determine the suitable sensor specifications for the geological applications, the users' demand and relationship between hyperspectral sensor's specifications including ground resolution, spectral resolution, swath and SNR are analyzed. Specifications of high resolution and wide swath hyper-spectral sensors for geosciences are proposed. Both large area searching and specific area monitoring in details can be achieved with the specifications system, which can facilitate further development of hyperspectral remote sensing in geological applications. ©, 2015, China University of Geosciences.
