A linear object position data generating method and generating system capable of achieving improvement in efficiency of data transmission by compressing effectively resample data of a linear object like a road profile on a digital map in terms of a resample processing method is provided. A linear object is resampled at a predetermined resample length, and respective angular information of a plurality of resample points on the linear object, which are set by the resample, are acquired. Then, markers representing additional information corresponding to at least one resample point are set, and incidental code values representing incidental codes of the angular information and the markers are decided. Then, a starting-point block, an angle/marker block, and an incidental-code block are generated, then these blocks are compressed individually, and then these compressed blocks are linked together. |
