Mobile Guiding System for Parks Based on Highly Precision Electronic Map
نویسنده
چکیده
Mobile Guiding System for Parks based on highly precision electronic map is of many researchers' concern, but commercial software cannot perform GPS positioning on custom-made maps for parks, and is not accurate enough to satisfy the requirements for drawing high precision electronic maps. This study uses trajectories measured by My Tracks software and a map edited in JOSM software to implement a custom-made electronic map. By processing GPS data gathered by smooth filtering, k-mean algorithm, mean filtering, and weighted-averaging (SKMW), it calibrated a custom-made map for a park mobile guiding system, based on a design from the gvSIG Mini open source project. Using Beijing JiuFeng National Forest Park as a case, this study developed LBS and SNS related service functions. The field test shows that the SKMW method can effectively improve the accuracy of a custom-made electronic map, and the practicality and expandability of a park mobile guiding system.
