| 1. | It can provide wetland information to the biggest , this must be advantageous to eye estimation
这样组合的合成影像能够最大程度地反映湿地信息,有利于目视解译。 |
| 2. | Optimal band selection and combination of multi - spectrum data is the key for image enhancement , it directly influences eye estimation and object information distilled
多光谱遥感数据的最佳波段选取与组合是遥感图像增强处理的关键部分,直接影响到图像的目视解译和研究对象的信息提取。 |
| 3. | The investigation method of soil losses status includes methods of conventional survey and qualitative remote sensing ( that is visual interpretation method on image or image processing on remote sensing )
水土流失现状调查的方法，主要有常规地面调查法和定性遥感方法(也称卫片目视解译法、遥感数据处理法) 。 |
| 4. | The result of the estimation demonstrated that the fused images had higher spatial resolution while maintaining the basic spectral contents of the original tm images , and the visual effect and the accuracy of the classification bad been greatly enhanced
评价结果显示，融合后的图像既保留了多光谱图像的丰富光谱信息，又不同程度提高了空间分辨能力，很大程度上改善了目视解译效果和自动分类效果。 |
| 5. | We have therefore adopted an innovative methodology that integrates auto - classification , visual interpretation and gis processing together , to maximise the usage of available data for the production of lup and lut , yet to minimise the impact on the demand on resource and time
鉴于此，我们采用了将自动分类、目视解译和gis处理整合的创造性方法，以便最大限度地利用现有资料编制土地利用图和土地利用表，尽可能降低对资源和时间的要求。 |
| 6. | Visual interpretation , on the other hand , usually produces better classification results that are more compatible with traditional lup . the disadvantage of this approach is the high demand on human resources and time if the production of lup relies entirely on visual interpretation
另一方面，目视解译通常能产生与传统土地利用图相容、效果更佳的分类。但是，如果完全依靠目视解译来绘制土地利用图，则弊端极为明显，即：对人力资源和时间的要求过高。 |
| 7. | This paper takes qingdao as the study field and uses 1995 and 2000 year ' s tm materials , then gets the data about the quantity and change rate on qingdao city ' s land use , and finally analyze the condition of qingdao city ' s land use dynamic changes
以青岛市为研究区,利用1995 、 2000年两期的tm遥感影像资料,运用人机交互目视解译方法以及地理信息系统的空间分析和数理统计功能,得到青岛市土地利用变化数量、变化速度等数据,对青岛市土地利用变化情况进行了深入分析 |
| 8. | It can increase information quantity , improve vision effection , and therefore advance the explanation ability of one frame of image , by carrying out data fusion with remote sensing images got from different satellites or with images of different bands got from same satellite
对中巴资源一号卫星的零级数据的实际处理获得很好的效果。对不同卫星的遥感图像或同一卫星的不同波段的图像进行融合，可以提高单幅图像的信息量、增强视觉效果，进而提高目视解译能力。 |
| 9. | Based on the rank system of rock desertification and the remote sensing and geographical system , the author uses the visual interpreting ways of interchangeable human - machine to establish a 1 : 100000 data base of rock desertification space . the data indicates that the rock desertification areas above the medium degree in guizhou province are 13187km2 , covering 7 . 49 % of the province ; whereas those above the minor degree are 35920km , covering 20 . 39 % of the province
在石漠化等级体系的基础上，在遥感和地理信息系统的支持下，采用人机交互式目视解译方法，建立了1 : 10万的石漠化空间数据库，结果显示目前贵州省中度以上石漠化面积13187km ~ 2 ，占到7 . 49 ，轻度以上石漠化面积35920km ~ 2 ，占到全省的20 . 39 。 |
| 10. | It is discovered that the correlation between msavi ( modified soil adjusted vegetation index ) and vegetation coverage is higher than that between ndvi ( normalized differential vegetation index ) and grassland coverage when the land cover is low . so msavi can be used as the main index of grassland desertification degree . in order to evaluate the precision of the result , different methods such as supervised classification , unsupervised classification and visual interpretation on image are tried respectively
本文将其作为草地沙化的分级指标，直接通过计算分级，建立msavi等级与草地沙化程度的对应关系，确定草地沙化的程度，然后将msavl分类结果分别与目视解译、监督、非监督分类的结果进行了精度比较，其精度高于监督与非监督分类，与典型区现场绘制和目视解译结果的误差为5 . 9 ，能满足草地沙化监测实际应用要求。 |
