Adjacency Effect Measurement and Data Analysis
遥感邻近效应测量与数据分析

Supported by NSFC, we have carried out the research on adjacency effect since 2004 and conducted 2 satellite and 1 aerial synchronous experiments. The experiments on May list and July 25th, 2005 and the results analysis were introduced in this paper. With improved measurement design and measurement device, data are analyzed by comparing the spectral curves from ground measurement, flat platform measurement and framed platform measurement, the results show that the improved measurement can prevent more scatter lights to come in the adjacent measurement system. Two adjacent effect analysis results show that if the two pixels have the same brightness there are mutual adjacent influence source and the influence strength is around 12.5% , if the two pixels do not have the same brightness, the influence strength toward weaker pixel, in other word the less brighter pixels get more adjacent effect.
