Embodiment
As shown in Figure 1, in the preferred embodiment of the present invention, specifically comprise following computer software process step:
101) first the position of each point is shown on map according to the longitude of GPS and latitude data;
102) when the accuracy of map zooms in or out time, GPS location precision according to the map should change display position automatically;
103) calculate the distance between mutual 2 on map, calculate the space length between 2 according to GPS position information, calculate the precision size apart from the rear map according to current display, calculate the pixel distance shown on interface between 2.
104) after obtaining the pixel distance between 2, judge 2 dot spacings from value, if be greater than the value of setting, think that location comparison is apart far away, can not think in the scope of a Vertex cover.
105) if the distance between obtain 2 is less than the value of setting, think in the coverage of same point, now think that they are in same point range.
Whether 106) when the accuracy of map is exaggerated or after reducing, recalculate pixel distance between points, with equally rejudging above in the coverage of same point.
107) when one of them some position changes, do the calculating of this point and other some distances equally, judge whether in same point coverage, just can delete from list if do not have this to put, if in this point, just add this point in list.
