Changeset comment- geoMapTool
Why should I use Changeset
Comments?
• Out of courtesy to your fellow
mappers,
• To avoid misunderstandings
• To increase the value of your edit
and prevent edit wars
• As an aide memoire
You must add a
changeset
comment

OpenStreetMap –
wiki Good changeset
comments

In the field
Good practices for general mapping:
 Ensure there is OSM data created by desktop mapping
 Ensure mobile phone is fully charged
 Have a mapping plan

In the field – Mapping residential buildings
Good practices for mapping residential
buildings:
 Respect home owner’s/tenant’s privacy
 Do NOT put the name of tenants in the “name” attribute
 If possible where an identifier clothing that indicates you are a
volunteer working on a mapping project for community
resilience

In the field – Mapping commercial buildings
Good practices for mapping commercial
buildings:
 Many stores can exist in one commercial building – to map this
properly following the below steps (see example below).
1. Record the attributes of the building
2. Add points on top of the building to indicate the name of the
store in the commercial building

Changeset comment- geoMapTool
A 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"
