Vector layers
Vector layers contain individual geometries. They are useful for planning data, boundaries, search areas, routes, tracks and imported project information.
Practice
Offline Data
Prepare maps, POI, overlays, themes and terrain for offline use.
Workflow
Suggested Flow
Use these steps to combine maps, data and tools for the task.
- Choose data sourceTreat map, overlay, POI, terrain or theme as separate data types.
- Use smart importImport the file and check the suggested target.
- Activate terrainUse HGT, DEM GeoTIFF, ASC or DTED for elevation profiles, hillshade, contours or viewrange.
- Test the profileCheck map, layers and theme in the map profile and keep only needed data active.
Terms
Separate maps, vector layers and raster overlays clearly
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 | Data sources for elevation values and terrain analysis. They are not a visible map in the narrow sense, but provide height information. | 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 |
Raster overlays
Raster overlays are finished image surfaces above the map. They are useful for aerial imagery, historical maps, scans or special map views. Opacity is often adjusted so the base map remains visible below.
Show or use
Maps, vector layers and raster overlays can be shown on the map. Elevation data is usually used by tools: point elevation, elevation profile, hillshade, contour lines and viewrange.
Download
Download data from the provider first
The practical workflow stays simple: choose a suitable source, download the file, check the license, import it through Android's file picker, then activate map, vector layer, raster overlay, POI data or elevation data in the profile.
