[HOT] recruitment: new volunteer training

[John Whelan]

Generally it's best to refer to the HOT project by number rather than by 
title.  It just makes it less confusing.

HOT has a lot of beginner mappers and if it is project 750 you are 
referring to then I wouldn't describe the instructions as clear for 
beginners.

For example map primary roads as primary.  Yes but a beginner might 
think that primary means the tag for the lowest or simplest type of 
highway.  There is room for confusion here and remembering back to 
efforts to make things idiot proof remember that idiots are evolving 
everyday.

Projects that concentrate on just one aspect such as roads or buildings 
have even simpler instructions and less room for the novice to go wrong.

polygon #26 I suspect most of us would describe this as tile 26.

It also talks about please use the hosted imagery and accept the 
NextView License.  Mark the source as Bing.  This sounds like Bing is 
not the source.

To my mind one of the most pressing needs is data quality.  This means 
validation is important.

You are mapping in Openstreetmap which means the official way to correct 
something is the make a changeset comment and see if you get a 
response.  With HOT mapping we see a lot of novice mappers who map for 
perhaps once or twice then disappear.  In JOSM you can look at the 
history <crtl>h and my rule of thumb is if they have less than 5 edits 
and last mapped 4 years ago just correct it. Obviously there is a 
judgement call between such a mapper and one with 25,000 edits who 
mapped this morning and has used a different tag to perhaps one you 
might use.

There is also just drag the entire project into JOSM and look for 
duplicate buildings etc.

Have fun and you may bug me directly with questions.
