基于电子地图的农产品地理二维码设计

传统二维码只是简单的属性信息的表达，缺乏地理信息内容。为了研究农产品产地地理信息空间可视化的表达，通过对二维码空间属性分析,提出地理二维码概念,建立起产地-产品-消费者的信息查询及溯源渠道。农产品地理二维码通过与电子地图相结合的方式将农产品产地空间位置信息以图像的形式呈现给消费者,满足消费者对农产品来源的关心,实现农产品来源有迹可循和查询方便快捷的目标,维护农产品品牌权益。以陕西紫阳县富硒茶为例,进行了基于电子地图的农产品地理二维码设计。

Design of Geographic Two-dimensional Code of Agricultural Products Based on Digital Map

Traditional QR codes are simple expressions of attribute information, but lack geographic information content. The paper aims to visualize of the spatial information of agricultural production area. Through the analysis of the spatial attributes of two- dimensional codes, the concept of geographic twodimensional codes is proposed, and the origin-product-consumer information inquiry and traceability channels are established. The agricultural product geographical two-dimensional code integrates the digital map with the spatial location information of the production areas in the form of images to be passed to the consumers, aiming to satisfy the consumers’concern about the source of agricultural products, establish the channel of traceability of agricultural products’sources and realize the quick and easy query to safeguard the rights and interests of agricultural products brands. Taking the selenium-enriched tea in Ziyang County of Shaanxi Province as an example, a geographic map code for agricultural products based on digital maps was designed.
