Original如何将经纬度利用Google Map API显示C# VS2005 Sample Code日前写了一篇如何用GPS抓取目前所在,并回传至资料库储存,这篇将会利用这些回报的资料,将它显示在地图上,这个做法有两种,最简单的就是直接传值到Google Maps上. 举例来说,当我们知道经纬度后,只要将数据套到以下网址即可. http://maps.google.com/maps?q=25.048346%2c121.516396 在参数q=后面,就可以加上经纬度了. 25.048346是Latitude纬度 %2c是空格 121.516396就是Longitude经度了. 范例画面: 而另一种做法就比这个复杂一点,要使用Google API来做,首先,要使用google API就必需要有google的帐号,没帐号是无法申请的,当有google的帐号后,就可以到http: //code.goog

Take the current mobile phone as an example: Get the current mobile address, and then convert from latitude to detailed address (including: Country name-Country code, province, city, street name, postal code, etc.). 1: Get the current mobile phone latitude and longitude degree Reverse Geoder Class 1:-(void) Startedreversegeoderwithlatitude: (double)

In a three-dimensional system, you must determine the sun position based on time and set this position as a specific light source. To produce real lighting and shadow effects The method for calculating the longitude and latitude of the direct sun point is as follows: Based on the basic geographic knowledge, Latitude: the lat
