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.

Data center
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.
Terms
Wyraźnie rozróżniaÄ mapy, warstwy wektorowe i nakÅadki rastrowe
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 | Źródła danych dla wartoÅci wysokoÅci i analizy terenu. Nie sÄ widocznÄ mapÄ w ÅcisÅym sensie, ale dostarczajÄ informacji o wysokoÅci. | 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
Warstwy wektorowe zawierajÄ pojedyncze geometrie. SÄ przydatne dla danych planowania, granic, obszarów wyszukiwania, tras, Åladów i importowanych informacji projektu.
Raster overlays
NakÅadki rastrowe to gotowe powierzchnie obrazu nad mapÄ . SÄ przydatne dla zdjÄÄ lotniczych, map historycznych, skanów lub specjalnych widoków mapy. CzÄsto reguluje siÄ przezroczystoÅÄ, aby mapa bazowa pozostaÅa widoczna.
Show or use
Mapy, warstwy wektorowe i nakÅadki rastrowe mogÄ byÄ wyÅwietlane na mapie. Dane wysokoÅci sÄ zwykle używane przez narzÄdzia: wysokoÅÄ punktu, profil wysokoÅci, cieniowanie, poziomice i zasiÄg widocznoÅci.
Źródła
Skąd pobrać dane offline?
ArxSilex MapTools nie dołącza cudzych danych mapowych. Pobierz pliki od właściwego dostawcy, sprawdź licencję i format, a następnie świadomie zaimportuj je do aplikacji.
| Typ danych | Odpowiednie źródła | Uwagi |
|---|---|---|
| Mapy bazowe offline | 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, warstwy i dane OSM/GIS | BBBike Extracts Geofabrik Downloads | BBBike i Geofabrik dostarczają wyciągi OSM oraz formaty GIS, takie jak GeoJSON, Shapefile lub GeoPackage. Nie każdy format surowy jest bezpośrednio mapą aplikacji; importuj tylko obsługiwane formaty. For Geofabrik, the relevant app format is usually .gpkg.zip when a GeoPackage download is available for the selected region. |
| Dane wysokościowe i terenowe | 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. |
| Nakładki rastrowe i mapy specjalne | Portale open data | Portale urzędowe, open data lub własne projekty GIS mogą dostarczać GeoTIFF, KML/KMZ, MBTiles lub GeoPackage. Przed importem sprawdź georeferencję i prawa użycia. |
| Style renderowania | 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. |
| Licencja i aktualność | - | Źródła mogą wymagać atrybucji, rejestracji, limitów użycia lub mieć własny rytm aktualizacji. Aplikacja nie obsługuje tych dostawców i nie zastępuje ich licencji. |
Formats
Which offline data is used for what
The app treats maps, warstwy wektorowe, nakÅadki rastrowe, POI data, elevation data and map styles 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. |
| Vector layers and nakÅadki rastrowe | GPX, GeoJSON, KML, KMZ, LOC, JSON, GeoPackage, GeoTIFF, Shapefile ZIP | Vector and raster data can be prepared as additional layers. Visual GeoTIFF belongs to nakÅadki rastrowe; 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, elevation data ZIP | Used for point elevation, route elevation profiles, hillshade, contours and viewrange. GeoPackage DEM is not intended for these elevation queries. |
| 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, elevation data archives and POI databases need storage and can take time to import or index.
Deletion
Imported maps, warstwy wektorowe, nakÅadki rastrowe, POI data, elevation data and map styles can be removed in the relevant data areas. App data can also be cleared through Android.
