We usually do map positioning, mainly by latitude and longitude to accurately locate a location.But, we are human ah, we are not satellites AH.The user on the map to find a place, we can not tell him, this place is longitude how many degrees, latitude how many degrees.We're going to have to tell somebody a place name, right?That's what we're talking about today in geocoding and geo-coding.Geocoding: You say a place name, such as "West Lake", we give y

The Address Resolution Service of Google map API is free of charge currently. You can convert the detailed address to the longitude and latitude.The test HTML file is as follows: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> However, this relies on the support of Google's online service interfaces. If Google leaves the Chinese market one day or there are other reasons that it will no longer open these service interfaces, it will be impossi

The map application GNOMEMaps3.10 is used to log on to the Ubuntu14.04s Software Center. GNOMEMaps is an interesting map application that features a striking and lightweight look that gives users the best map experience. GNOMEMaps comes with the zoom-in/zoom-out function. With a Global Map (equipped with OpenStreetMap), street views are supported when you drag and move the cursor over a region, country, or city. Start GNOMEMaps and you will notice its

Now MarcosCostales has started the UbuntuTouchGPS navigation application. Every Ubuntutouch mobile phone user can get the app for free through the Ubuntu store, an intuitive GPS navigation. Based on OpenStreetMap and OSRM, this application provides accurate and up-to-date maps. Allows you to set the destination, arrival time, and redirection to show how many miles you have traveled and how far you are away from the destination. The speed indicator can

Geographical searches with latitude and long1_part I Calculating the distance between two geographical locations is a common feature of Web 2.0 applications. this is usually a two-step process. firstly, obtaining the latitudes and longitudes of the locations from their addresses, a process known as geocoding. secondly, calculating the great-circle distance between these two points and doing something meaningful with this value. In this first of a 2
