摘要:
为进一步挖掘资源一号02C卫星(ZY1-02C)数据在土地整理业务中的应用潜能,以内江市威远县界牌镇响罗村土地整理项目为例,以ERDAS,AutoCAD和ArcGIS软件为工具,通过内业核查与外业核查相结合的方式,提出利用ZY1-02C数据进行土地整理项目验收核查的技术路线和操作流程,并对该技术的可行性和准确性进行分析.实际应用表明,利用ZY1-02C影像进行土地整理项目验收核查,能准确解译土地平整工程内的地类情况、灌溉与排水工程中的山平塘情况以及田间道路工程中的田间道整治情况;但对于囤水田田坎、排水沟、蓄水池以及错车道等工程,难以从ZY1-02C影像上判读;对于工程施工质量,则无法从ZY1-02C影像判读.根据应用评价结果得出,ZY1-02C数据能为土地整理项目验收核查提供技术支撑,可用于土地整理项目验收核查工作.
Abstract:
The purpose of this paper is to study the potential application of ZY1-02C satellite data when they are used in the checkup of land consolidation project. The land consolidation project in Neijiang of Sichuan Province was selected as a case study for this research. Based on the software including ERDAS,AutoCAD and ArcGIS,the authors carried out the indoor verification and the field investigation to put forward the complete technical method and operation procedures by using 02C satellite data for the check up of land consolidation project. The results show that the 02C satellite images could be used to evaluate the cultivation in land leveling project,the shanping pool in irrigation and drainage engineering,and the field road in road project. Nevertheless,the projects,such as the bank of paddy field,field drain,water tank and the passing track,can hardly be checked. The quality of project cannot be evaluated. The conclusion of the paper is that the 02C satellite image can be used in land consolidation project checkup.
