OpenStreetMap Geography Awareness Week


A global coalition of partners are hosting mapping events at colleges, community

centers and other institutions to map places around the globe, following the

Geography Awareness Week 2015 theme, “Explore! The Power of Maps”

OpenStreetMap (OSM)


The OSM project (http://www.openstreetmap.org) was born in 2004 to encourage

the creation of geo data that could be free to use and shareable with anyone.

Why OpenStreetMap?


Geospatial data is not free in many parts of the world.

Anyone can contribute – from people without any geo-training/skills to highly

skilled people and geo people

How to map with OSM?


1. Create the geometry of the feature

2. Add tags to the feature

A tag is composed of a key and a value EXAMPLE: building = hotel→VALUEKEY

2. Add tags to the feature

highway = service

surface = asphalt

amenity = bicycle_parking

building = university

name = Gino Cassinis

Let's start to map!


http://api06.dev.openstreetmap.org

A test iD demo is available to play around with OSM edits without making real

changes to the OSM map.

Open the following link, sign up and map:

Many different editors are available to edit the OSM map:

- iD (Web-based Javascript editor)

- Potlatch 2 (Web-based Flash editor)

- JOSM (desktop-based Java editor)

- Vespucci (Android editor)

- many others, see http://wiki.openstreetmap.org/wiki/Editors

Humanitarian OSM Team


The Humanitarian OpenStreetMap Team (HOT) has the objective of creating and

providing free and up-to-date maps in case of natural disasters or political crises.

Missing Maps project


Whereas HOT maps in response

to disasters and conflicts, the

Missing Maps project maps in

anticipation of crises by

identifying the places where the

most vulnerable people live.

OSM Tasking Manager


The mapping job is divided into smaller tasks that can be completed rapidly.

This approach facilitates the distribution of tasks to the various mappers in a

context of emergency and allows to control the progress of the work done.

OSM Tasking Manager


✔ Today's mapping tasks:

➔ OSM beginners

➔ OSM experienced mappers✗ South Kivu, Democratic Republic of Congo TASKS #1301, #1302,#1309

(description & video: http://osmgeoweek.org/project/south-kivu)

✗ Lubumbashi, Democratic Republic of Congo – TASKS #1254, #1332

✗ Unity State, South Sudan – TASK #1053

✗ Kampala, Uganda – TASK #1334

map focus is on single buildings

map focus is on roads and residential areas

✔ Before starting...

➔ create an account on http://www.openstreetmap.org

http://osmgeoweek.org/project/south-kivu

19

OSM Tasking Manager – instructions


✔ Type the task number on the search bar and click the task title

20



✔ Under the Description tab you can read the general task description

21



✔ Under the Instructions tab you find the detailed instructions for mapping

22



✔ Under the Contribute tab you can start mapping (either be receiving a random subtask or by selecting a subtask on the map)

23



✔ Under the Contribute tab you can start mapping (either be receiving a random subtask or by selecting a subtask on the map)

➔ empty polygons represent areas where mapping has to be completed (if the border is orange the area is locked, i.e. a user is working on it)

➔ yellow polygons represent areas where mapping has been completed and is waiting for validation

➔ green polygons represent areas where mapping has been completed and validated

24



✔ After login, select an empty polygon on the map and click Start mapping

25



✔ Choose iD editor as the OSM editor to be used for mapping

26



✔ Draw the elements asked in the instructions (roads, buildings, etc.)

27



✔ Add the hashtag #mapathonpolimi in the changeset comment and save!

28



✔ If there is still work to do in this area, press Unlock; if you think the work in this area is completed, press Mark task as done

29



✔ Experienced mappers can also check if yellow areas have been completed and validate them. If validation is positive, the areas become green.
