What is openstreetmap? The openstreetmap “one-liner”

A web project to create a free and open map of the entire world, built entirely from volunteers surveying with GPS, digitizing aerial imagery, and collecting and liberating existing public sources of geographic data.

Facts on remote OSM work in Haiti

OSM data in SHP & GPS map extracts (Garmin) available day 1; WFS day 2

OSM = roads core data set (OCHA Core Data sets check-list).

OSM data used as SHP, WFS, WMS in responders mapping production

26 hours to get imagery released and 48 hours to get 1st imagery loaded on the OSM platform available for tracing

Day 1 Day 28

Tasking server – walking paper

Combined, GPS and Walking Papers can be used for rapid surveying and ground truthing.

Walking Papers allow users to print out small sections of the OSM map. In the field, these paper maps can be used to draw new features, annotate existing data, and take notes that will help with the import of GPS data.

Icons in each of the corners and a unique code for each Walking Paper let users scan the paper and upload to OSM so the notes can be viewed in an editing environment.

 The analysis shows that, where OSM was collected by severalusers and benefited from some quality assurance, the qualityof the data is comparable and can be fit for many applications.

The positional accuracy is about 6 metres, which is expectedfor the data collection methods that are used in OSM. Thecomparison of motorways shows about 80% overlap betweenOSM and OS .
