Recommended 25 of PHP's most useful class libraries, 25 PHP non-class libraries Snappy Snappy is PHP5 used to generate thumbnails, snapshots, pdf,url or HTML pages. It incorporates excellent webkit based wkhtmltopdf and wkhtmltoimage that can be adapted to the windows of the Osx,linux. Geocoder Geocoder can help you build a geo-aware application. It provides an abstraction layer for geocoding operations.

Placemark (the object of the mkplacemark class) is actually an attribute of geocoder (the object of the mkreversegeocoder class. Obtaining placemark from geocoder is not much different from directly obtaining placemark.

This article illustrates the implementation of Android's address information display via the location API. Share to everyone for your reference. Specifically as follows: The Android Locatin API allows you to display specific latitude and longitude address information through the Geocoder class. Such as: By Geocoder Method Getfromlocation () can get the list of address objects. I only take one address resu

P.s: in this article, you will find a way to obtain the latitude and longitude Based on the city keyword, that is, to obtain the latitude and longitude through the reverse latitude and longitude query interface of the Google map API.Google map APIIs a powerful map API, many well-known websites are using Google map API, once I also wrote a program based on visitors or even domain names to query latitude and longitude (http://js8.in/mywork/ipsearch ).
