Transfer (http://www.findingchina.info/article/gps/2009-10-10/108.html) Preface: for some purpose that few people do not know the truth, the electronic map (including GPS navigation software) of tianchao abolished the function of displaying the longitude and latitude of the current position. This is a good opportunity for a few G-friends who wish to freely share accurate locations, a few outdoor enthusiasts, and a few who want to know geographical kno

Abstract: The previous chapter teaches you how to build your own administrative region map. This time, we will provide you with a visual selection of regions and the ability to automatically generate longitude and latitudeCode. ToolSource codeIt is completely open and detailed annotations are made. It can be used either as a tool or as a learning case for Baidu map API. Tool description: 1. The switch can be controlled to determine whether to create a line covering on the map. 2. Double

Because the GPS signal positions are longitude and latitude spherical coordinates, the State cannot directly reference them from a security perspective. Therefore, kailide gridded the coordinates of longitude and latitude to facilitate the navigation of the navigators, each grid unit represents a vertical direction of 0.1 seconds. The specific format of the K-code is as follows: 1. The K code is a 9-
