"OSM Arbitrary Excerpt Export" (OSMaxx) 
Geospatial data from the unique and worldwide OpenStreetMap project, prepared für map visualization and analyses in GIS. Cuts out (extracts or excerpts) OpenStreetMap data, processes it to geodata and converts it to typical GIS fileformats before being prepared for download.
Geodaten des einzigartigen und weltweiten OpenStreetMap-Projekts aufbereitet für Kartenvisualisierung und Analyse in GIS. Schneidet OpenStreetMap-Daten aus (exract, excerpt), bereitet sie zu Geodaten auf und gibt sie als GIS-Fileformate ab.

Description
German 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.
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.
