to list and describe

Geographical objects

Where do you want to go to?

Alice in Wonderland…

Would you tell me, please, which way I ought to go from here?''That depends a good deal on where you want to get to,' said the Cat.'I don't much care where —' said Alice.'Then it doesn't matter which way you go,' said the Cat

Motivation and Goal

De Wikimedia en OpenStreetMap (OSM) organisatie en vrijwilligers delen heel

wat principes. Het zou goed zijn als gemeenschappelijke projecten kunnen worden opgezet en

ondersteund. Wikipedia, Wikidata en Wikimedia Commons kunnen worden gebruikt

samen met OpenStreetMap om onderlinge linken vast te leggen en te tonen. Wikimedia

objecten kunnen worden gekoppeld in OpenStreetMap via node tags (labels, key-value pairs).

Dit laat toe om nog meer metadata, beschrijvingen en multimedia te verzamelen en te

documenteren over geografische objecten. OpenStreetMap interactieve kaarten

kunnen worden getoond in Wikipedia-artikels. Wikidata kan doorverwijzen naar OSM objecten.

OpenStreetMapSystem architecture and objects

Graphical Editors

OpenStreetMap Architecture

Geographic/geospatial tool anddatabase

Multiple (web) Editors depending on complexity

Multiple Coordinate systems (in the background)

Aerial images (Google, Bing, AGIV)

Database driven

Query tool(s)

Map production, and GUIs

Objects = nodes = way

Open source, Open data

OpenStreetMap Objects

Locations: coordinate EPSG systems & Projections

Attributes & Values: object type, name, address, characteristics

… Entities, attributes, relationships

… Generic data model ~ Wikidata

Pictograms

Object (Nodes)

Examples

(way)Point amenities, monuments, shops, services

Line rivers, roads, walls, fences

Polygon buildings, land lots, industrial zones, landuse, forests, agriculture, lake

OpenStreetMap EditorsEditor Platform Complexity Functionality

iD Browser Intermediate• (good quality) AGIV aerial images• Easily create roads, buildings, land use• Add labels (key/values)

PotlatchBrowser and Adobe Flash-

playerSimple

• Bing aerial images• Choose icons• Drag and drop• Show coordinates

JOSM Remote Control

Java 8 Complex• Requires special Java client application• Requires additional software,

infrastructure, training

Merkaartor LinuxStandalone application

• You can work offline• For experts - Very fast• You can download one or multiple tiles• With subsequent merge and synchronisation• Very efficient when you need to update a lot of

nodes

OsmAnd Android Easy • Add POI

Map Rendering

Offline / online / device specific

Web browsers

Android tablet, iPad, smartphone; OsmAnd

(vector) Tiles and (automatic, manual) map download

Multiple layers (car, bike, foot, ski, tourism, thematic)

Depending on scale (omitting details)
