Abstract Wide-area polynomial approximation can be used to fit the disturbing gravity of a given region. This can reach high accuracy with great efficiency. However, 24 nodes’ value of the vice domains, which are connected to main domain, must be used when we calculate with this method. If the main domain is located on particular places, such as the vertices of the area, not all the nodes’ value of vice domains can be used. As a result, fitting accuracy is dragged down. This circumstance is researched in the paper, in which the accuracy and efficiency between wide-area polynomial approximation and inverse distance weighting are compared. Finally, an improved project is put forward, which made the fitting effect better
