[HOT] duplicate mapping

[john whelan]

It sounds silly but I come across things being mapped twice often uploaded
with a fifteen minute gap.

If you're leading a maperthon could you please ask your mappers to upload
every fifteen minutes or so to reduce this.

If you're mapper the same suggestion applies.

Thanks John

Cristian,

There might be some others on this list that know the area, but you might have 
better luck asking on the OSM India mailing list or forum; both links can be 
found on the WikiProject India page: 
http://wiki.openstreetmap.org/wiki/WikiProject_India 

Hope that helps,

Subject: [HOT] Looking for a contact with OSM contributors in the area of 
Varanasi, Uttar Pradesh, India

Hi.

I am Cristian and I am member of OpenStreetMap Italia. I have been asked
by a student - at the University of Bergamo, Italy - that wants to
perform some analysis on OpenStreetMap around the area of Varanasi,
Uttar Pradesh, India if I could put her in contact with some local OSM
contributors. Does anybody contribute to OSM in that area or can you
point me towards some local user and/or group?

Thank you.

Cristian

Re: [HOT] Mapping buildings with new mappers at a maperthon

scratch, why not just do so and use ctrl+shift+g to preserve history?

Probably because I have very little interest in correcting buildings.

 Hi,

 A lot of this would be addressed if iD had a building mapping tool
 like JOSM does. I am going to restart the effort to get that added in
 to iD, I have some new ideas for how we might be able to accomplish
 it. I think it would save literally hundreds of hours volunteer time
 fixing buildings that are mapped by new mappers and help new mappers
 increase their productivity and accuracy.

 iD is by far the more approachable editor for OSM, it
