国家地理格网编码与二维条码的集成应用之探讨

Discussion on integration and application of National Geographic Grid code and two-dimensional bar code

国家地理格网是一套穿越各级行政境界和地图尺度范围的无缝平面坐标系统,不但定位容易、使用方便,并且精度可根据不同应用目的而变化。条码技术作为一种关键的信息标识和信息采集技术,已在全球范围内得到了迅猛发展。本文将着重讨论地理格网编码与二维条码的集成方法,并探讨集成后二维条码的应用前景。

National Geographic Grid is a seamless plane coordinate system which passes through all or different levels of adminis- trational borders and scales of map. It is easy not only to use and determine position, but also to resize different precisions based on ap- plication aims. As an information identifying and collecting method, the bar code technique has developed rapidly on a global scale. This paper discussed the integration of National Geographic Grid code and two-dimensional bar code, and explored the application fore- ground of two-dimensional bar code after the integration.
