The use of Baidu Map API to achieve GPS coordinates to Baidu coordinates of the batch coordinate conversion (such as 1000 points)

conversion request sent first reaches the program. If there is no control, due to network reasons, it is possible that the data requested for conversion will arrive first. Program, so you do n’t know who responded to the returned data, that is, you ca n’t find the correspondence between the coordinates after correction and the coordinates before correction. Use

Convert GPS coordinates to Baidu coordinates

=============== Problem description ==================== To convert the GPS coordinates collected by mobile phones to Baidu coordinates, I found the code on the Internet: GeoPointgeoPoint3=newGeoPoint((int)((mLat1+0.001)*1E6),(int)((mLon1+0.003)*1E6));GeoPointGeoPointBaidu=CoordinateConvert.fromWgs84ToBaidu(geoPoint3);mOverlayList.add(newOverlayItem(GeoPointBaid

GPS coordinates to Baidu map coordinate method

First you need to know the GPS coordinate system. The GPS coordinate system follows the WGS-84 standard, under which the GPS chip can emit different packet formats. The GPS data can be classified into Gpgga, Gpgsa, GPGSV, GPRMC and so on, according to the different frame-frame head of the data. These frame headers iden

Calculate the distance between two GPS coordinates

Scenario: the longitude and latitude coordinates of two GPS points are known. Calculate the distance between two points. 1.Distance/latitude relationship GPS: 22.514519, 113.380301 GPS: 22.511962, 113.380301 Distance: 284.6439379583341 Jl_wd = 284.6439379583341/(22.51451-22.511962) = 111712.6915064105572998430141
