Journal Article
TL;DR: In this article, the authors made a fundamental proof of the connection between the incidence angle and the height precision, as well as the extent that the incidence angles may affect the correcting precision.
Abstract: The correcting precision may be affected by the incidence angle during correction of satellite images.This article clarifies the reason why this influence occur and the extent it may achieve.Meanwhile,we make a fundamental proof of the connection between the incidence angle and the height precision,as well as the extent that the incidence angle may affect the correcting precision.Moreover,through an experimental approach,the vality of our conclusion was confirmed.It is supposed that,with this analysing method used in manufacture,resources can be arranged properly,and reasonable judgement can be made for quality of the products.

Journal Article
TL;DR: The scale effect problem in remote sensing information extraction was studied in this article, where the targets' fractal dimensions, compact ratio, areas, mean value, standard deviation and mean differential to neighbors were experimental researched.
Abstract: The scale effect problem in the remote sensing information extraction was studied.The targets' fractal dimensions,compact ratio,areas,mean value,standard deviation and mean differential to neighbors were experimental researched,which finds that that these index values of all targets would fluctuate with scales,and different targets in the images have different feature values and scales.It is necessary to extract the region of interest in optimal scale images.
