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.

Prepare offline data deliberately
Offline use is more than one map file on the device. A useful field view depends on matching maps, POI, elevation models, overlays, profiles and map styles.
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.
Offline status
The offline status shows whether map, POI, elevation data, active profile and map style are available for a position or whether online tiles would still be needed.
Profiles and visibility
Map profiles combine map, active layers, terrain, POI display and map style. This lets you switch between outdoor, field and specialist views.
Licenses 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.

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 Downloads | 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 terrain 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, layers, POI, terrain and themes separately. The same file format can have different targets depending on its content.
| Area | Supported 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. |
| Layers and overlays | GPX, GeoJSON, KML, KMZ, LOC, JSON, GeoPackage, GeoTIFF, Shapefile ZIP | Vector and raster data can be prepared as additional layers. Visual GeoTIFF belongs to raster overlays; DEM GeoTIFF belongs to terrain. |
| 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. |
| Terrain and elevation features | SRTM .hgt, DEM GeoTIFF .tif/.tiff/.geotiff, ESRI ASCII Grid .asc, DTED .dt0/.dt1/.dt2, terrain ZIP | Used for point elevation, route elevation profiles, hillshade, contours and viewrange. GeoPackage DEM is not intended for these elevation queries. |
| Render themes and 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 profile.
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 profiles before entering an area without coverage.
Limits
What is different offline
Offline data 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, terrain archives and POI databases need storage and can take time to import or index.
Deletion
Imported maps, layers, POI, terrain and themes can be removed in the relevant data areas. App data can also be cleared through Android.
