| 2 | Application of Earth Remote Sensing and GIS in Mapping Land Cover Patterns in Kinangop Division, Kenya显示文摘Land cover is a fundamental variable that links many facets of the natural environment and a key driver of global environmental change.Alterations in its status can have significant ramifications at local,regional and global levels.Hence,it is imperative to map land cover at a range of spatial and temporal scales with a view to understanding the inherent patterns for effective characterization,prediction and management of the potential environmental impacts.This paper presents the results of an effort to map land cover patterns in Kinangop division,Kenya,using geospatial tools.This is a geographic locality that has experienced rapid land use transformations since Kenya's independence culminating in uncontrolled land cover changes and loss of biodiversity.The changes in land use/cover constrain the natural resource base and presuppose availability of quantitative and spatially explicit land cover data for understanding the inherent patterns and facilitating specific and multi-purpose land use planning and management.As such,the study had two objectives viz.(i) mapping the spatial patterns of land cover in Kinangop using remote sensing and GIS and;(ii) evaluating the quality of the resultant land cover map.ASTER satellite imagery acquired in January 23,2007 was procured and field data gathered between September l0 and October 16,2007.The latter were used for training the maximum likelihood classifier and validating the resultant land cover map.The land cover classification yielded 5 classes,overall accuracy of 83.5%and kappa statistic of 0.79,which conforms to the acceptable standards of land cover mapping. This qualifies its application in environmental decision-making and manifests the utility of geospatial techniques in mapping land resources. | Kennedy Okello WERE Andre KOOIMAN | 2010 | 遥感学报2010，14，1： | 1 |

| 4 | 加拿大局域多点通信系统现场测试显示文摘加拿大通信研究中心对一个28 GHz的先导性局域多点通信系统的现场测试在一个 5 km半径内的395个地点进行,以评估系统的可用性。可用性与地势、通道间隔和发射机/接收机天线高度有很大关系。另一个值得注意的一点是,对这两个单元,在预想的 5 km半径之外的地点也有效。该试验的目的是要验证在不存在大的障碍的小范围内,下变换后的信号功率(SPAD Signal Power After Downconversion)没有大的变化。从结果可见,在一个区域内SPAD仅变化几个分贝,而且所有测试结果与假定在自由空间传播时计算的SPAD曲线非常吻合。还需要开展的研究包括:关于在不同气候和季节条件下的长时间可用性;为获得更好的频谱效率和可靠性的高级调制与信道编码;业务之间的干扰和高屋顶定向接收天线的安装。为获得较好的可靠性和/或较高的数据传输能力,CRC现正评估不同的调制技术,也正计划对双向通信业务中需要的返回通道的有关问题进行研究。 | 吴奕彦 姜有保 Bernard Caron Alain Bergeron Benoit Ledoux Pierre Bouchard Andre Kennedy Michele Guillet | 2000 | 电视技术2000，24，4： | 0 |
