"OSM Arbitrary Excerpt Export" (osmaxx)
The source of worldwide geospatial data for interactive and printed maps and for geospatial data analysis. Cuts out OpenStreetMap data, processes it to geodata and converts it to typical GIS fileformats before being prepared for download.
Die weltweite Geodatenquelle für interaktive und gedruckte Karten und für GIS Analyse. OpenStreetMap-Daten ausschneiden, zu Geodaten aufbereiten und als typisches GIS-Fileformat konvertiert abgeben.

Technical
Some explanations (incomplete):
- Selected OSM objects are transformed into Osmaxx tables (feature classes / layers). Some objects are captured in OSM as point, some as linestring or as area - and often both as point and area.
- All tables names contain a hint which geometry type they contain:
- poi_p => POIs with point geometry,
- roads_l => line/multilinestring,
- poi_a => area/multipolygon.
| Table Name | Description |
|---|---|
| adminarea_a | Administrative boundaries range from large groups of nation states right down to small administrative districts and suburbs, with an indication of this size/level of importance. |
| adminunit_a | From sep. validated source. |
| boundary_l | The boundary is used to mark the borders of areas, mostly political, but possibly also of other administrative areas. |
| building_a | To mark the outline of the area of the building. |
| (coastline_l) | From separate source. |
| landuse_a | Land use describes the human use of land, for example fields, pastures, and settlements. |
| military_a | See military_p. |
| military_p | The military is for buildings and land used by the military. |
| natural_a | see natural_p. |
| natural_p | Used to describes natural physical land features, including ones that have been modified by humans. |
| nonop_l | non-op./planned infrastructure not usable for traffic. |

Notes
- Das Zielschema umfasst echte Geometrien (Punkt, Multi-Linestring, Multi-Polygon) und ein GIS-Datenmodell (Highways, Railways, Buildings, etc.).
- Zur Aufbereitung in das Zielschema gehört u.a. ein Postprocessing, dass die heterogenen OSM-Daten homogenisiert (z.B. Restaurants als Punktobjekte, auch wenn sie in OSM als Gebäudefläche erfasst wurden).
- Ein zusätzliches Zielschema enthält routingfähige Strassen. Dieses wird als Teil des Garmin-Formats abgebegen.
- Abgabeformate sind GIS-Fileformaten (GeoPackage, Shapefle, File Geodatabase) sowie ein Navi-Format (Garmin .IMG).
- Es werden auch Karten-Symbologien für QGIS und ArcGIS abgegeben, passend zu den GIS-Fileformaten.
