This value is normally the average value for the whole ground area covered by the pixel. Surface spectral data were collected along a transect through the center of the lake prior to the Hyperion overpass.

The final product is an estimate of the top-of-atmosphere (TOA) spectral radiance, which is compared to Hyperion and ALI radiances. www.nexosproject.eu The initial objectives for the TRW Hyperion team was to characterize the on-orbit performance as thoroughly as possible and to compare with pre-flight characterization test data. Also include in Table 1 is the Hyperion VNIR, and SWIR pixel corresponding to the field measurem, indicated in Table 1, all four sites correspond to approxim, the moisture between the time of the field measurements (December 17-20, content. Another focus of the project is improving access to difficult to find, yet valuable data by developing web crawlers to discover descriptions of data and services that are ready to be brokered. The new generation of Landsat, the Landsat Data Continuity Mission carrying the Operational Land Imager (OLI), has improved SNR and high radiometric resolution. The capacity of reproducing spectral feature by EO1-Hyperion has been checked on bright pixels (ice-snow) in the acquired image. Interpretation of these data, with the aid of numerical models which allow inference of multiphase cooling histories, indicate three discrete cooling events that are likely to correlate with sedimentation events in surrounding depositional settings. The approach presented here may be particularly useful for remote and inaccessible volcanic areas and also represents a potentially powerful tool for the exploration of extraterrestrial volcanic surfaces. over, share and access data. Figure 1-2 – Summary Of Primary EO-1 Instrument Characteristics. The first four months of mission life were focused on instrument activation, functional checkout, and performance verification. Calibration techniques and tradeoffs between alternative approaches are discussed. The goal is to characterize air-fall deposits, recent lava flows, and old lava flows based on their spectral reflectance properties and on the textural characteristics (grain size) of pyroclastic deposits at an active basaltic volcano. Abstract: A calibration experiment was orchestrated on February 7, 2001 at the Salar de Arizaro, Argentina to assess the on-orbit radiometric and spectral calibration of Hyperion. y sector and the GEOSS and Copernicus stakeholders. Moreover, the observed differences in the field spectra of volcanic surfaces have been compared with differences in the signal intensity detected by airborne LiDAR survey showing the possibility to include information on the texture of volcanic surfaces at Mt.
