Ground calibration targets (GCTs) play a vital role in atmospheric correction of satellite sensor data in the optical region, but selecting suitable targets is a subjective and timeconsuming task. This paper describes a method to automatically select suitable GCTs, using a combination of remotely sensed multispectral and topographic data. Desirable characteristics for GCTs sites were identified...

Automatic program execution control is a demanding tool for heteroge neous environments due to the variable availability of processors and network band width Issues such as load distribution have to be re analyzed since strategies developed for homogeneous machines fail to optimize the computation time in heterogeneous net works The nal user should not be involved in deciding which machines sho...

This paper looks at a data set, called the SHARE 2010 collect, that has been designed to analyze the various impacts of illumination change on materials. Similar fabric materials were placed on different backgrounds where spectral signatures were analyzed to determined impacts of background adjacency. Hyperspectral, multispectral, and LiDAR modalities were used to image the panels in the above ...

The paper describes an approach to reason ing about actions and plan generation within the framework of description logics From an epistemological viewpoint our approach is based on the formalization of actions given by dynamic logics but we exploit their corre spondence with description logics to turn the formalization into an actual implementation In particular we are able to carefully weaken...

An expert system developed for use with geologic materials (minerals) has been modified to more generally analyze spectra of all types of materials, including manmade materials, military targets, and background. The methodology requires reflectance spectra, but can also be extended to emissive measurements in the mid-wave infrared (MWIR) and long-wave infrared (LWIR). The spectra of known mater...

Guangxi Province is one of the regions more serious desertification. This paper using ENVI image processing system, according to remote sensing image interpretation target mark and image spectral characteristics, found remote sensing interpretation model of the background information of forest, shrub and grass, agricultural land, surface water, towns, roads from TM and ETM data from 1988 to 200...

A specific task of distributed and parallel Information Systems is workflow management. In particular, workflow management systems execute business processes that run on top of distributed and parallel Information Systems. Parallelism is due to performance requirements and involves data and applications that are spread across a heterogeneous, distributed computing environment. Heterogeneity and...

'Dynamic hypertext ' is hypertext which is automatically generated at the point of need. A number of NLG systems have now been developed to operate within a hypertext environment; and now that these systems are becoming widely available on the World Wide Web, it is useful to take stock of how well-equipped NLG technology is to work in this new domain. A generation system in a hypertext environm...
