"OSM Arbitrary Excerpt Export" (osmaxx) Osmaxx Logo 16x16.png

The source of worldwide data for interactive and printed maps and for geospatial data analysis. Cuts out (extracts or excerpts) 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. Schneidet OpenStreetMap-Daten aus (exract, excerpt), bereitet sie zu Geodaten auf und gibt sie als GIS-Fileformate ab.

Project

Project staff (mainly from Geometa Lab HSR):

  • Stefan: Lead and concept
  • Raphael: Coordination, integration, frontend and backend
  • Tobias: Frontend (Javascript, ...)
  • Nicola: Backend (Python, PostgreSQL, ...)
  • Dhruv: PostGIS loading and schema transformation/data homogenization
  • Van An: QGIS symbology

Former staff members:

  • Eugene: PostGIS loading and schema transformation/data homogenization
  • Lukas: Extraction tool chain (Linux tools, ...)
  • Martin: ArcGIS symbology (ArcGIS)

Map Gallery

This gallery shows some maps made with Osmaxx data using QGIS styling (see also Making Maps from OpenStreetMap Data):

  • Rapperswil (Switzerland)

  • Frankfurt (Germany)

  • Asmara (Eritrea)

  • Tacloban City (Philippines)

  • Port-au-prince (Haiti)

  • Nairobi (Kenya)

  • Gaza (Palestine)

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.
