使用OruxMaps的离线地图（卫星图、路线规划、3D地形、GPS和兴趣点）
我想分享一个我在过去几个月里一直在研究的设置。目标是为一个国家准备一个完整的离线地图系统，能够在没有互联网连接的情况下工作。
想象一下，如果互联网断了，或者你在一个没有网络覆盖的偏远地区旅行，大多数地图应用程序将变得无用，因为它们依赖在线服务。我想要的是在这些情况下仍然能够使用的解决方案。
我使用了Android应用程序OruxMaps（https://play.google.com/store/apps/details?id=com.orux.oruxmaps）——我与开发者没有任何关联——准备了一个完整的离线数据集，包括：
• 覆盖整个国家的卫星影像
• 用于地形阴影和3D可视化的高程数据（DEM）
• 使用BRouter的离线导航数据
• OpenStreetMap的兴趣点
• 额外的山脉和徒步旅行兴趣点
• 完整的3D地形可视化
一旦数据安装完成，所有功能都可以在手机上本地运行，无需网络连接。
最终的结果基本上是一个完整的离线GIS风格的地图系统，可以放进你的口袋里。这是一个非常强大的工具，适合徒步旅行者、实地研究人员、应急规划人员或任何在网络连接不可靠地区旅行的人。
准备和组织这些数据集花费了相当多的时间，因此我考虑编写一个指南或准备现成的离线地图包，以便那些想要类似设置的人无需经历整个过程。
我很好奇这里是否还有其他人尝试过这样的完全离线地图设置。
如果有人需要帮助设置类似的系统，请随时联系我——我的邮箱在我的个人资料中。

I wanted to share a setup I’ve been working on over the past few months. The goal was to prepare a complete offline mapping system for an entire country that works with zero internet access.<p>Imagine the internet goes down, or you’re traveling in a remote area with no network coverage. Most map apps become useless because they depend on online services. I wanted something that still works in those situations.<p>Using the Android app OruxMaps (https://play.google.com/store/apps/details?id=com.orux.oruxmaps) — I have no affiliation with the developers — I prepared a full offline dataset including:<p>• Satellite imagery covering the entire country
• Elevation data (DEM) for terrain shading and 3D visualization
• Offline routing data using BRouter
• OpenStreetMap points of interest
• Additional mountain and hiking POIs
• Full 3D terrain visualization<p>Everything runs locally on the phone once the data is installed. No network connection is required.<p>The result is basically a complete offline GIS-style mapping system that fits in your pocket. A very powerful tool to have. This could be useful for hikers, field researchers, emergency planning, or anyone traveling in areas where connectivity is unreliable.<p>Preparing and organizing the datasets took quite a bit of time, so I’m considering writing a guide or preparing ready-to-use offline map packages for people who want a similar setup without going through the whole process.<p>Curious if others here have experimented with fully offline mapping setups like this.<p>If anyone needs help setting something like this up, feel free to reach out — my email is in my profile.
