Vector layers
Vector layers contain individual geometries. They are useful for planning data, boundaries, search areas, routes, tracks and imported project information.
实践
地图与配置文件
使用离线地图、图层、栅格叠加层和渲染主题构建地图配置文件。
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.
工作流程
建议流程
按照这些步骤为任务组合地图、数据和工具。
- 选择底图为任务选择在线地图、Mapsforge、MBTiles 或 GeoPackage。
- 添加主题导入兼容的 Mapsforge 渲染主题 ZIP 并启用。
- 控制图层仅在需要时启用栅格叠加层、POI 和地形。
- 保存配置文件将地图、图层和主题保存为可复用配置文件。
