The invention relates to an angle conversion algorithm for ArcGIS polar vector field visualization, which is characterized in that vector field data and longitude data are read, and a vector field angle taking a specified direction as a reference direction is obtained through angle conversion and correction. The algorithm capable of converting vector field angle data in IDL software before visualization for ArcGIS polar vector field visualization correctly expresses the physical meaning of a vector field and makes up a defect that the ArcGIS cannot correctly draw the polar vector field.
