The invention belongs to the technical field of offline track compression, and provides an offline track compression method which comprises the following steps: S1, normalizing an original track T to form a track T1; s2, compressing the track T1 for the first time by adopting neighbor synchronous clustering to form a track T2, and then compressing the track T2 for the second time by adopting a course speculation algorithm to form a track T 'to complete the compression of the current layer; and S3, automatically increasing the number of the layers, calculating an allowable error epsilon i of the current layer, detecting whether the number layer of the current layer reaches a set layer threshold value Lm or not, if the detection result is no, taking the track T'as the track T1 of the next layer, executing the step S2, and if the detection result is yes, outputting the compressed track T '. According to the method, the track is compressed from different dimensions, secondary compression is performed on the compr
