Derby/Chaddesden Ward

The table below gives details of progress of mapping the roads in Chaddesden Ward. The street names, road reference numbers and grid references are taken from OS OpenData Locator (see Ordnance_Survey_Opendata).

Please help to improve and update this table, which will help identify the remaining mapping work to be done.

Streets should be marked as mapped only when the full length of the street is mapped, and it is named. If the name in OpenStreetMap differs from that in the OS data, please note this in the notes field - the difference between the names could be a result of the OS's error rather than ours so don't change it on OpenStreetMap without visiting the street to check which is correct. Adding the date of when something was last mapped or checked could also be helpful in the future to identify whether data could be out-of-date.

Abbreviations/codes/terms used in the table

• OSL - indicates that the name was derived from OS OpenData Locator rather than by survey.
• OSSV - mapped only by tracing over Ordnance Survey Opendata StreetView, instead of by a survey. It would be useful to carry out a proper survey of these streets in the future, to verify that the street exists and is correctly mapped on OS StreetView, and to map details which are missing from OS StreetView (eg whether the street is one-way, other restrictions).
• Not present - indicates that there were no shops, amenities etc present on that road at the time of mapping.
• No addresses - no buildings have an address on that particular road.
