describe a concept, a map overlay: All overlays or overlays to the map, collectively referred to as map overlays. such as callouts, vector graphic elements (including: Polylines and polygons, and circles), positioning icons, and so on. Overlays have their own geographic coordinates, and when you drag or zoom the map, t
Today, because of the needs of the work, the previous compilation of a GPS test program has been revised again. This program is a bit of a history, I wrote 11 years, when I learned how to develop Android, is an experimental work. Now the work needs to be put back out to fix. At the same time I found that the Android GPS

From: http://www.linuxidc.com/Linux/2011-09/42454.htm Concepts and basic classes Recently I learned GPS, so I made a GPS signal parsing tool on the Android system (HTC G7 mobile phone). The following is a summary. Thank you for your correction. Function: 1. obtained the location GPS information, including longitude a
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
1. Rewrite the batch conversion js provided by Baidu to achieve 100 coordinate points at a time 2.Using recursive callbacks to control the return sequence of coordinate transformations to ensure that a set of coordinates (a set of 100) requested first arrives first First, let's take a look at two examples of coordinate transformation in the demo of Baidu Maps API: Convert original coordinates to Baidu coordinates: http://developer.baidu.com/map
I have developed GPS-related embedded software for several years, So when talking about a program to test the GPS positioning module, the first reaction is to read the data from the GPS module through the serial port, and then parse the NMEA format data of GPS. Today, due to work needs, I took out a previously written
