SESSION OUTLINE

WHAT IS OPENSTREETMAP(OSM)?OSM is a collaborative, user-driven, free to use mapping platform that allows people to create a map of the world. OSM maps are unlike Google maps because the data that is used to create the map can be modified and downloaded for use.

All OSM data is created under the Creative Common license Attribution-ShareAlike 2.0 (CC BY-SA 2.0). You are free to copy, distribute, transmit and adapt OSM data, as long as you credit OpenStreetMap and its contributors by using ‘Data © OpenStreetMap Contributors’ as the source

OpenStreetMap is spelt as one word but it is often abbreviated to ‘OSM’

WHY USE OSM?

OSM allows users to trace buildings, roads, landuse features and more using satellite imagery. These features are created either as points, lines or polygons.

Additional information can be added to each feature, for example. A building can be traced in OSM and you can added information about the material of the building, how many floors it has, the address, if it has a basement and lots more.

USE OF OSM TO STRENGTHEN RESILIENCEDuring a disaster information is crucial, a detailed, up-to-date map overlaid with damage assessment and needs assessment help in response

Before a disaster, detailed and up-to-date maps overlaid with hazard information can be used to prepare for disaster and address areas for disaster risk reduction

Use OSM to create the detailed and up-to-date map of your community to strengthen resilience

Your first question may be…..Where and how do I access

OpenStreetMap?

Open an internet browser (either Google Chrome, Mozilla

Firefox or Internet Explorer)

Google Chrome

Once confirmed, you are ready to use OSM. Welcome to

OpenStreetMap!

When you access OpenStreetMap again

after you have set up your account, you

can click on the Log In button.

Enter your account credentials

and click on the LogIn button.

Click on Remember Me checkbox

to save your account details

LOGGING IN

USING OPENSTREETMAP

To move or to pan, hold down the

left mouse button and drag your

mouse to the left, right, up or down.

If you have a mouse with a scroll

key, you can scroll up to zoom in

and scroll down to zoom out.

You can navigate in OpenStreetMap by using your mouse.

Hold down to Pan

Use for Zooming In & Out

USING THE SEARCH PANEL

To go to a specific place, use the Search panel and type the name of

the area you are looking for.

Type the name of your municipality and click Go.

A Search Results window will

appear listing down all matches of

your search query.

Scroll down and look for the

specific name of your search query.

Click on the correct match.

OpenStreetMap automatically zooms in to the match area of your

search query.

LEGENDS

To understand the various map feature view the legend by selecting

the icon shown below in the right side panel.

MapKey provides the

symbol and its

corresponding ground

feature it represents.

MapKey is available

for the Standard Map

Style only.

VIEWING MAPS IN DIFFERENT MAP STYLES

In OpenStreetMap, data can be interpreted and view in different map

styles

Click on the Layers button in the Tool panel

found at the right side of the map

AVAILABLE MAP STYLES

We have five (5) available map styles.

Standard

Cycle Map

Transport Map

MapQuest Open

Humanitarian

STANDARD MAP STYLE

Standard Map Style is the

default tile layer in

OpenStreetMap.

CYCLE MAP STYLE

Cycle Map Style primarily aimed to

show information for cyclists.

It shows cycling routes and other

specific features such as:

Cycle tracks and routes

Bicycle parking

TRANSPORT MAP STYLE

Transport Map Style shows public

transport lanes like railways and

buses.

MAPQUEST

MapQuest is an online mapping

company based on the United

States and owned by AOL.

MapQuest is the first large online

mapping service to embrace

OpenStreetMap.

HUMANITARIAN MAP STYLE

Humanitarian Map Style focuses on

developing countries with an

emphasis on features related to

development and humanitarian work.

EDITING MODE IN OSM

In order to adding buildings, roads, bridges and more to the OSM map you need to go into ‘editing’ mode

Once the region of interest has been chosen and you have zoomed into the area select ‘Edit’ on the upper left toolbar as shown.

Choose ‘edit with iD (in-browser editor)’

It is recommended to choose the ‘take a walk-through of the editor’

SATELLITE IMAGERYSelect a background image

for mapping

Choose the layers tab in the

side panel

Select the imagery provided

in the list.

Note: you should check all

imagery to see which is the

best for your mapping needs

CUSTOM MAP BACKGROUND

Custom Map

OSM allows the user to upload or tile

their own custom map background. This

could be updated satellite imagery or

high resolution drone imagery of an

area with new or improved

infrastructure.

Custom maps are found in the side

panel of the OSM online website.

CUSTOM MAP BACKGROUND

Once the custom map is added it will be seen overlaid on top of the base layer.

New layer added of drone imagery

CUSTOM MAP BACKGROUND

This custom layer can then be used as the background image for

mapping of new buildings and added data in specific locations.

Mapping and adding data to the map is shown in the next step.

ADDING FEATURES TO THE MAP

Adding buildings, roads, bridges and more

Once the region of interest has been chosen the user can add buildings, roads, locations and more by tracing them using the satellite imagery provided. The first step is to choose which feature type needed.

Feature types and their uses:

Points – regions of interest, specific landmarks, locations

Lines – roads, paths, walking trails

Area – all buildings, houses, parks, sports fields

ADDING FEATURES TO THE MAP

In this example we have mapped a building by tracing the outline with

the ‘area’ tool. Click on the outside of the building to form a polygon and

double click when finished to close the shape.

SAVING YOUR EDITS Save your edits by clicking on the save button as shown below. It’s good

practice to save you edits every 10 minutes.

You must add a ‘changeset comment’

CHANGESETCOMMENTS

A changeset is a group of edits made by one user in a relatively short time. When you upload a changeset, the editor you are using will give you a chance of entering a changeset comment which should describe your edit.

Source: OpenStreetMap – wiki Good changeset comments

CHANGESET COMMENTA good changeset comment should concisely and adequately describe an edit. Real

examples of good changeset comments include:

"Added buildings in industrial area."

"Add a footpath link from Donnington Close to Roman Way based on local knowledge"

"Updating Danish street addresses from OSAK (AWS): Bag Hegnet"

"Updated Algonquin Park boundary"

"Add country roads and cycleway SE of Newport"

"Köln: Nicht-Kreisverkehre, 'junction=roundabout' entfernt, Vz 215 nicht vorhanden" (German for

"Cologne: Removed junction=roundabout from non-roundabouts, traffic sign 215 not present")

"added a few tidal inlets to the coastline of Maranhão"

"Added houses and house numbers based on Bing and local knowledge. Some house numbers could

sadly not be found."

Some changeset comments are useless and bring none of the benefits that a changeset

comment can bring - again real examples:

"BBOX:3.23,41.96,3.23,41.96 ADD:14 UPD:0 DEL:0"

"151005-DE-FUe"

"Edit uploaded via ArcGIS Editor for OpenStreetMap feature service dec20 at 1/13/2012 9:56:00 AM"

"some fixes"

ADDING DATA TO THE MAP

Once completed more known information

can be added about this location. These

maps created on the desktop application

can be shared with a mobile device to

people in the field for verification and to

add more on the ground information.

THANK YOU FOR COMPLETING THE OPENSTREETMAP
