我怎样才能实现在Android的离线地图。我试图与mapsforge库。 它不为威斯康星州二进制映射文件。那么，怎样才能创建自己的地图二进制文件？

How can i implement offline map in android. I tried it with mapsforge library. It does not provides binary map file for Wisconsin state. So How can create my own map binary file ?

在此先感谢。

推荐答案

您将需要两件事情：

一个程序，让您使用mapsforge库。关于这一点，你可以叫AdvancedMapViewer的程序，将其视为与图书馆为例棒。

a program that allows you to use the mapsforge library. Concerning this, you can stick with the program called AdvancedMapViewer which comes as an example with the library.

映射文件。 Bascially你必须创建自己的映射文件从OpenStreetMap的数据。这是通过一个插件的渗透。这个插件描述如下：

a mapfile. Bascially you have to create your own mapfile from OpenStreetMap data. This is done with a plugin for Osmosis. This plugin is described here:

的https://github.com/mapsforge/mapsforge/blob/master/docs/Getting-Started-Map-Writer.md

在短期它的工作原理是这样的：

In short it works like this:

在安装反渗透（ http://wiki.openstreetmap.org/wiki/Osmosis ） 安装的插件（的https://github.com/mapsforge/mapsforge/blob/master/docs/Getting-Started-Map-Writer.md) 下载数据（例如，从geofabrik.de： HTTP： //download.geofabrik.de/north-america/us/wisconsin-latest.osm.pbf ）

运行渗透任务，因此（在你的路径与渗透）在shell中运行这样的： Install Osmosis (http://wiki.openstreetmap.org/wiki/Osmosis) Install the plugin (https://github.com/mapsforge/mapsforge/blob/master/docs/Getting-Started-Map-Writer.md) Download the data (e.g. from geofabrik.de: http://download.geofabrik.de/north-america/us/wisconsin-latest.osm.pbf)

run the osmosis task, thus run this on a shell (with osmosis in your PATH):

渗透--read-PBF威斯康星latest.osm.pbf --mapfile作家文件= wisconsin.map

osmosis --read-pbf wisconsin-latest.osm.pbf --mapfile-writer file=wisconsin.map

然后把你的设备上创建的文件wisconsin.map和AdvancedMapViewer加载它。

then put the created file wisconsin.map on your device and load it from AdvancedMapViewer.
