建立经验统计遥感信息模型时数据处理中的C Toolkit方法

C Toolkit Method in Data Processing for Establishing Experiential Statistical Model of Remote Sensing Information

在分析建立经验统计模型过程的基础上,为解决样地点数据与遥感影像的自动配准问题,采用C Toolkit模块,运用EML(Erdas Macro Language)语言和Visual C++6.0语言,开发了数据自动转换模块,并将模块镶嵌在ERDAS软件中。结果表明:该模块具有强大的数据转换功能,并具有实用价值;运用C Toolkit模块进行二次开发,打破了运用空间建模工具进行二次开发的局限性,简化建模过程,避免手工输入引起的误差,提高了反演精度。

Data transformation module was developed and embedded in the ERDAS software using C Toolkit module, Erdas Macro Language and Visual C ＋ ＋ 6.0 language in order to resolve the problem of automatic image registration of data from out-side investigating sites and remote sensing image. Result shows that this module has powerful data transformation function and practical value. The secondary development was carried out with the C Toolkit module. The limitations of the secondary development of the spatial modeling tool were overcome.
