2. OpenStreetMap 13th ICOM 2009-08-16Andreas Oxenstierna What is OSM? One world-wide geographic database with many contributors – “GeoWiki” Phocus on streets – but also other features like land cover and POI Geometry types: Nodes, ways and closed ways (“areas”) Relations – group of geometries (Data Primitives) GPS-measured – quite good accuracy but not so detailed Stored in latitude/longitude – rendered in spherical Mercator projection Map Features with defined tags (common and extensible object model) Profiles like OpenCycleMap (specific tags and rendering)

4. OpenStreetMap 13th ICOM 2009-08-16Andreas Oxenstierna Why? Geodata is expensive, difficult to order and to use Especially true for vector data (and orienteering map data …) Object models are not standardized (ISOM is a notable exception) “Free” alternatives (e.g. Google Maps) are proprietary How? Database – PostgreSQL (earlier MySQL) Editors – Potlatch (Flash), JOSM (Java), Merkaator (Qt, i.e. C++) Interactive editing (GPS tracks) and batch import Renderer – Mapnik (out: raster tiles) and Osmarender (out: SVG) Runs on Linux, Mac and Windows OpenSource – all software (except maybe OS) More info www.openstreetmap.org http://wiki.openstreetmap.org/wiki/Main_Page

6. OpenStreetMap 13th ICOM 2009-08-16Andreas Oxenstierna COMO David Svantesson has created COMO, which might stand for Collaborative Orienteering Mapmaking Online or with Open software i.e. a potential alternative to OCAD and PC-Mapper and includes: MFStandardMFStandard Map Features Standard (object model stored as specific OSM tags) EditorEditor: JOSM or Merkaartor RenderRender: Osmarender (i.e. SVG files) OCAD Conversion toolsOCAD Conversion tools - converting between OCAD, OSM and COMO Local storage as OSM XML files or in OSM database (MySQL or PostGIS) i.e. no collaborative data contribution or ”OpenOrienteeringMap” More info http://como.oxtract.se http://wiki.openstreetmap.org/wiki/IOFmapping

7. OpenStreetMap 13th ICOM 2009-08-16Andreas Oxenstierna COMO – current best test map Issues: Another purpose Early days WYSIWYG editing Printing Projection Render from OSM data Ownership Pros: Database Common software OpenSource software Standardisation – ISOM tags Use OSM data
