用于离线视图的JMapViewer ADD切片 [英] JMapViewer ADD tiles for offline view

问题描述

您好，我正在Java中使用此示例尝试加载OpenStreetMaps离线图块，

Hello I'm using this sample in Java to try to load OpenStreetMaps Offline tiles,

例如，我在C:/OSM/tiles/

for example I have my tiles on C:/OSM/tiles/

但是我需要知道如何在地图(JMapViewer)类中添加此信息以在本地加载图块.

but I need to know how to add this information in map (JMapViewer) class to load tiles locally.

非常感谢您的帮助，这是我的消息来源:

推荐答案

我直接由源代码编译并更改

I compile by the source directly and change

\ org \ openstreetmap \ gui \ jmapviewer \ tilesources \ AbstractOsmTileSource.java

\org\openstreetmap\gui\jmapviewer\tilesources\AbstractOsmTileSource.java

这是JMapViewer.zip/JMapViewer_src.jar内的源代码，提取Jar文件，并将文件夹/org复制到邮件源代码文件夹中

Here is the source code inside JMapViewer.zip/JMapViewer_src.jar extract the Jar file and copy the folder /org in the mail source code folder

http://svn.openstreetmap. org/applications/viewer/jmapviewer/releases/2011-02-19/JMapViewer.zip

并更改下一个

 public AbstractOsmTileSource(String name, String base_url, String attr_img_url) {
        this.name = name;
     // this.baseUrl = base_url;
        this.baseUrl = "file:///C:/OSM/tiles";
        attrImgUrl = attr_img_url;
    }
