小班多边形专题自动接边技术及其应用

Automatic Edge Match Technology between Subcompartment Polygon Themes and Its Application

对数字林相图的误差进行了分析 ,定义了误差多边形、误差专题、最大误差直径、误差平均直径等几个基本概念。应用ArcView中的Avanue编程系统开发了小班专题自动接边的程序 ,对黑龙江省上甘岭林业局查山林场和长青林场的小班多边形专题进行了摸拟接边操作 ,结果表明 ,接边操作是有效的并达到了预期效果 ,并给出相应的误差报告。

Journal of Northeast Forestry University.-2003,31(1).-12～16 The error of digital forest map was analyzed and the concepts of error polygon, error theme, maximum error diameter, average error diameter were given. Meanwhile the edg fitting program with Avanue of ArcView GIS was developed, with which hypothetical simulating for the subcompartment theme edge between Chashan forest farm and Changqin forest farm in Heilongjiang Province was performed. The results of execution indicate that the program is valid and reaches the expectation.
