Local, not cloud
Imported offline data is stored in app-owned storage or at a file location you choose. There is no ArxSilex cloud sync for maps, POI, terrain or projects.
离线
离线数据
提前准备地图、POI、高程模型、栅格叠加层和地图样式，让 ArxSilex MapTools 在没有移动网络时也能使用。

Data center
Prepare offline data deliberately
将当前底图与叠加层和导入的图层数据分开管理。
Import through file picker
The app uses the Android file picker. You select files deliberately; ArxSilex MapTools does not request broad storage access to the whole device.
Smart Import
Smart Import analyzes files by content and suggests a target: base map, layer, raster overlay, POI, terrain, render theme or project.
此位置的离线状态
在线地图可能会向外部地图提供商请求瓦片。如果希望此视图保持本地，请使用已导入的地图、POI 和地形数据。
地图预设
地图预设会保存全部四个地图槽、槽位顺序和活动槽，包括地图源、样式、图层、地形、叠加层、路由偏好和对象可见性。界面模式、坐标、颜色、图标收藏和菜单顺序仍是全局设置。
许可证 and sources
OpenAndroMaps, OpenStreetMap, your own GIS data, authority maps or commercial data may have their own license terms. The app does not automatically bundle external map data.
使用条款
清楚区分地图、矢量图层和栅格叠加层
ArxSilex MapTools uses these terms deliberately. They make it clear whether a file is used as a base map, editable geometry, image overlay or elevation data source.
| Term | Short definition | Examples |
|---|---|---|
| Maps | Base maps used as the main working view. | OpenStreetMap, OpenAndroMaps, offline .map, MBTiles as a base map |
| Vector layers | Additional object, line or polygon data above the map. The content consists of points, lines or areas and can often be displayed or evaluated individually. | GPX, KML, GeoJSON, Shapes, KML polygons, GeoJSON areas, GPX tracks as overlays |
| Raster overlays | Georeferenced image or tile data above the map. They are placed as a finished image surface and are not interpreted as individual objects. | GeoTIFF, MBTiles, image maps, aerial imagery, scanned maps, georeferenced plans |
| Elevation data / terrain | 数据来源 用于高程值和地形分析。它们并不是狭义上的可见地图，但会提供高度信息。 | HGT, DEM GeoTIFF, ASC, DTED |
| Map style | Rendering rules for vector maps. The style defines colors, symbols, paths, POIs, contour lines and other map elements. | OpenAndroMaps render theme, Elevate Theme |
| POI data | Search and display data for places and points of interest. | OpenAndroMaps .poi, custom POI files |
Vector layers
矢量图层包含独立几何对象。它们适用于规划数据、边界、搜索区域、路线、轨迹以及导入的项目信息。
Raster overlays
栅格叠加层是覆盖在地图上方的成品图像面。它们适用于航拍图像、历史地图、扫描图或特殊地图视图。通常会调整透明度，使下方的底图仍然可见。
Show or use
地图、矢量图层和栅格叠加层可以显示在地图中。高程数据通常由工具使用，例如点高程、高程剖面、山体阴影、等高线和可视范围。
来源
在哪里获取离线数据？
ArxSilex MapTools 不随附第三方地图数据。请从合适的数据提供方下载文件，检查许可证和格式，然后再有意导入应用。
| 数据类型 | 合适来源 | 说明 |
|---|---|---|
| 离线底图 | OpenAndroMaps General Maps OpenAndroMaps Countries and Regions Examples: Germany, Europe, USA, South and Middle America, Canada, Australia, New Zealand, Oceania, Asia and Middle East, Russia, Africa | For OpenAndroMaps, choose a world, country or regional map on the source page. Import ZIP files with Karte_Map in the name as Map/Custom; import POI_Normal...poi.zip as POI. |
| POI、图层和 OSM/GIS 数据 | BBBike Extracts Geofabrik 下载s | BBBike 和 Geofabrik 提供 OSM 摘取数据以及 GeoJSON、Shapefile 或 GeoPackage 等 GIS 格式。并非所有原始格式都能直接作为应用地图；请只导入受支持格式。 For Geofabrik, the relevant app format is usually .gpkg.zip when a GeoPackage download is available for the selected region. |
| 高程和地形数据 | Sonny LiDAR DTM Sonny DTM overview map USGS SRTM OpenTopography Copernicus Data Space | Sonny provides European digital terrain models as a source for elevation data. DTM 1" and DTM 3" are grids in arc seconds, roughly about 30 m and 90 m at the equator; DTM 20m and DTM 50m state the grid spacing directly in meters. Finer resolution needs more storage and import time. Use the overview map to find the matching coordinate/region, then select it on the source page. |
| 栅格叠加层和专用地图 | 开放数据门户 | 政府门户、开放数据门户或自己的 GIS 项目可提供 GeoTIFF、KML/KMZ、MBTiles 或 GeoPackage。导入前请检查地理配准和使用权。 |
| 渲染主题 | OpenAndroMaps Elevate | Use the OpenAndroMaps theme page for the Elevate mountain/hike theme. On Android, use the quick-install hint for the default maps app or download Elevate.zip and import it into ArxSilex MapTools as a theme. |
| 许可证和更新 | - | 数据来源可能要求署名、注册、使用限制或有自己的更新节奏。应用不运营这些提供方，也不能替代其许可证文本。 |
Formats
Which offline data is used for what
The app treats maps, 矢量图层, 栅格叠加层, POI data, elevation data and map styles separately. The same file format can have different targets depending on its content.
| Area | 支持ed data | Important for use |
|---|---|---|
| Offline base maps | Mapsforge .map, MBTiles .mbtiles, GeoPackage .gpkg | Mapsforge files, for example from OpenAndroMaps, are intended for vector maps. MBTiles and GeoPackage are used as tile containers or map catalog data. GeoTIFF is not a directly renderable base map here. |
| Vector layers and 栅格叠加层 | GPX, GeoJSON, KML, KMZ, LOC, JSON, GeoPackage, GeoTIFF, Shapefile ZIP | Vector and raster data can be prepared as additional layers. Visual GeoTIFF belongs to 栅格叠加层; DEM GeoTIFF belongs to elevation data. |
| POI and offline search | .poi, .db, .sqlite, .geojson, .json, .csv, .tsv, .txt, .zip | Searchable POI must be imported separately. An offline map file alone does not yet provide a complete local POI search. |
| Elevation data and terrain analysis | SRTM .hgt、DEM GeoTIFF .tif/.tiff/.geotiff、ESRI ASCII Grid .asc、DTED .dt0/.dt1/.dt2、GeoPackage .gpkg、高程数据 ZIP | 用于点高程、路线高程剖面、山体阴影、等高线和可视范围。受支持的 GeoPackage 高程数据也可用作地形源。 |
| Map styles | Compatible Mapsforge/Elevate-like theme ZIP files | Map and map style remain separate. External themes must be obtained separately and follow their own license. |
| Projects and exchange data | ArxSilex projects, GPX, KML, KMZ, GeoJSON, CSV, PDF, ZIP | Project and exchange formats can be stored or shared offline. Shared files leave the app only through your action. |
Preparation
Practical workflow before a trip
1. Choose the area
Check which region is really needed. Smaller, suitable datasets start faster and save battery and storage.
2. Import a base map
Import a Mapsforge .map file, MBTiles or a suitable GeoPackage. Then activate it in the map preset.
3. Import POI separately
If you want offline search, import POI data in addition to the map and check categories, size and indexing.
4. Add terrain
Import HGT, DEM GeoTIFF, ASC or DTED for elevation profiles, hillshade, contours and viewrange in the area.
5. Check status
Use offline status, Layers & Visibility and map presets before entering an area without coverage.
Limits
What is different offline
离线数据 is reliable as long as coverage, format and quality fit. Some features intentionally depend on external data or user action.
No automatic routing
The app displays and analyzes geodata, but it does not calculate automatic turn-by-turn routes along roads or trails like a routing service.
Coverage matters
Elevation data and POI only work where the imported files actually cover the area.
Online maps stay online
Google or OSM online maps can still request tiles from external providers. Choose imported maps and data for local use.
Storage and performance
Large maps, GeoTIFFs, elevation data archives and POI databases need storage and can take time to import or index.
Deletion
Imported maps, 矢量图层, 栅格叠加层, POI data, elevation data and map styles can be removed in the relevant data areas. App data can also be cleared through Android.

使用前准备
各项功能需要哪些本地数据
离线模式不会自动提供地图或地形数据。请提前下载或链接合适的文件，并确认覆盖整个工作区域。
高程与可视范围
点高程、剖面、山体阴影、等高线和可视范围需要有效的 HGT、DEM GeoTIFF、ASC、DTED 或受支持的 GeoPackage 高程数据。
路线规划与导航
本地寻路需要有效且兼容的 Mapsforge 矢量地图，并包含可用道路数据。如果没有合适道路，仍可使用直线或自由连接。已创建或导入的路线可以离线跟随。
地图、POI 与图层
离线地图、POI 数据库、矢量图层和栅格叠加层必须在本地可用，并在相应地图槽位中启用。
导入或链接后，请在数据中心或地图浏览器中核对数据源、覆盖范围和地图槽位。
当前工作流程
链接数据文件夹并在桌面端准备文件
MapTools 可以连接 Android 设备上的本地数据集合；可选的 MapTools Converter 可在 Windows 或 Linux 上协助较大的准备任务。
链接的数据文件夹
可通过 Android 文件夹选择器为整个应用或单个项目授权。MapTools 只列出文件夹第一层的文件，绝不会自动导入或启用内容。
避免不必要的复制
兼容的 Mapsforge 地图和地形源可以直接链接。其他文件会在确认后通过 Smart Import 分析并添加。
MapTools Converter
这款独立桌面应用可检查、裁剪和组合现有地图、POI 与高程数据，并导出与 MapTools 兼容的文件。处理完全在本地进行；源数据及其使用条款仍由相应提供方负责。
