ArcGIS Geoprocessing除了提供常见的GIS空间分析功能外,还支持建立复杂的地理处理模型来完成定制的地理处理任务.根据现有的干旱遥感监测模型,采用ArcGIS Geoprocessing技术实现干旱遥感监测模型的建模处理.并以重庆市2006年干旱数据为例进行处理,所得结果和同期干旱状况吻合.使用插件式GIS二次开发技术基于ArcGIS Geoprocessing实现了干旱遥感监测系统.与传统手工分布处理相比,在模型选取、数据转换、数据处理、产品制作等方面,自动化程度得到了极大的改进和提高.系统主要功能为:通过对遥感影像数据的干旱模型自动化处理,快速获取干旱结果空间分布,并生成相关产品为决策部门提供决策依据.
In addition to providing common GIS spatial analysis functions, ArcGIS Geoprocessing also supports the establishment of complex geo-processing models to accomplish customized geo-processing tasks.According to the existing drought remote sensing monitoring models, ArcGIS Geoprocessing technology is used to model the modeling of drought remote sensing monitoring models .Taking the drought data of Chongqing in 2006 as an example, the results are in good agreement with those of the same period.Using plug-in GIS secondary development technology to realize the drought remote sensing monitoring system based on ArcGIS Geoprocessing.Compared with the traditional manual distribution processing, The main functions of the system are as follows: Through the automatic processing of the drought model of remote sensing image data, the spatial distribution of drought results can be quickly obtained and the correlations are generated Products for decision-making departments to provide decision-making basis.
