Abstract: This paper explores the method of integrating Map World Yunnan into ArcGIS and assesses its application effect in the field of forestry. The forestry sector faces challenges with data timeliness and accuracy due to the delayed update of existing free remote sensing images. Map World Yunnan provides quickly updated and free geographic information resources, and its integration with ArcGIS significantly improves the efficiency and accuracy of forestry work. This paper details the steps and technical points for loading Map World Yunnan into ArcGIS, and demonstrates its application in forest resource management, planning, and supervision through practical cases. Despite limitations in image clarity, the advantages of this integration are notable. The study emphasizes the value of this practice and suggests its broader application in other fields.
