摘要:
借助GIS对图形(影像)、属性、时态数据存储、查询、分析以及管理的强大功能,对利用陕西省2003年全年的MODIS数据生成的不同时相的归一化植被指数(NDVI)、比值植被指数(RVI)、差值\环境植被指数(DVI\EVI)等多种植被指数,及其对应的MOIDS影像和空间位置(地图)数据进行存储,将必要的植被指数分析方法和分析模型整合到该GIS空间数据库之中,达到数据、方法、模型在基于GIS植被指数空间数据库中的集成与统一,以实现基于时相和波谱信息MO-DIS、ETM影像数据的显示、查询、分析、管理等功能。实践证明,在GIS空间数据库中将时相、波谱和空间位置信息应用到遥感影像植被信息的提取中,从分析遥感影像的植被指数空间信息出发,能够较好地实现对植被指数信息的认识,为研究不同地区的植被分类、农作物长势监测及地表植被变化等方面提供分析依据。
Abstract:
With the powerful function of GIS to storage of graph(image), attribute and the temporal data, inquiry, analysis and management, the different temporal vegetation index data(normalization vegetation index NDVI, ratio vegetation index RVI, the differential value\environment vegetation index DVI \ EVI and so on)which produced by the whole year(2003)MODIS data of Shaanxi Province, corresponding MODIS image and spatial location(the map)data was stored. The essential vegetation index application analysis method and the model have been conformed to the database to make the integration and unification of data, the method and model in the vegetation index based on GIS spatial database. And as while as to realize the function of data display, inquiry, analysis, management based on the temporal and spectrum information MODIS, ETM image data. The practice has proved that: using the temporal, the spectrum and the space position information which in the GIS spatial databases to the extraction of the remote sensing vegetation information to make it possible for remote sensing images to analyze the vegetation index information from another angle. It knows better about the vegetation index information and provided the analysis basis for the vegetation classification, the crops growing trend monitor and surface vegetation change and so on.
