![Page 3: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/3.jpg)
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’
![Page 4: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/4.jpg)
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.
![Page 5: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/5.jpg)
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

HUMANITARIAN MAP STYLE
Humanitarian Map Style focuses on
developing countries with an
emphasis on features related to
development and humanitarian work.
![Page 29: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/29.jpg)
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’
![Page 30: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/30.jpg)
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
![Page 31: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/31.jpg)
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.
![Page 32: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/32.jpg)
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
![Page 33: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/33.jpg)
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.
![Page 34: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/34.jpg)
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
![Page 35: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/35.jpg)
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.
![Page 36: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/36.jpg)
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’
![Page 37: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/37.jpg)
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
![Page 38: Lesson 1. OPENSTREETMAP Basic Operations](https://reader031.fdocuments.us/reader031/viewer/2022021923/5a6704647f8b9a91298b5519/html5/thumbnails/38.jpg)
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"
Source: OpenStreetMap – wiki Good changeset comments

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.
