Abstract: 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.
