Vector layers
Vector layers contain individual geometries. They are useful for planning data, boundaries, search areas, routes, tracks and imported project information.
实践
离线数据
为离线使用准备地图、POI、叠加层、主题和地形。
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。
- 选择数据源将地图、叠加层、POI、地形或主题作为独立数据类型处理。
- 使用智能导入导入文件并检查建议目标。
- 启用地形高程剖面、山体阴影、等高线或可视范围请使用 HGT、DEM GeoTIFF、ASC 或 DTED。
- 测试配置文件在地图配置文件中检查地图、图层和主题，并只保持所需数据处于活动状态。
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.
