1∶500,1∶1000,1∶2000系列数字化测绘产品的精度目标与实现

The Accuracy Requirement and Realization of 1∶500,1∶1000,1∶2000 Series Digital Surveying and Mapping Product

1∶500,1∶1000,1∶2000系列数字化测绘产品按其生产工艺和用途的不同其精度规格也不尽相同,但产品的精度状况始终是测绘生产部门与用户所关心的问题。本文列举了现行有关规范的相关精度指标、规格,并结合产品的用途、特点和测绘生产的实际,简要阐述精度目标的控制与实现过程,对测绘实际工作有一定的参考价值。

According to the difference of production technique and purpose of 1：500,1：1 000,1：2 000 series digital surveying and mapping product ,the accuracy requirements are also different. But the accuracy of product is always the core problem for surveying and mapping production departments and users. This paper listed the relevant accuracy index and specification of the present standards. Combining with the purpose and characteristics of products and surveying and mapping production, it briefly discussed the accuracy control and realization procedure. It has reference value for surveying and mapping practical work.
