Re: [HOT] Missing hospitals/

[Arne Kimmig]

Hi Joaquim and all,

I’m working on the same project and noticed yesterday that some residential 
areas I mapped a few days ago disappeared in Bing. Together with what you 
wrote, Joaquim, I assume that in some areas Bing might have changed to an older 
imagery version, but I’m not sure.

Regards
Arne

Re: [HOT] landuse=residential and routing problems

[Arne Kimmig]

Hi Marco,

Looking at your pictures I’d say that in both the highways are mapped too 
detailed.

My suggestions for mapping these:

-The main path is the one east of the res area. It is clear that it near to the 
res area and you don’t need to map every small access path to the village.
-also the two small villages to the west are nearby and IMHO don’t need extra 
access paths mapped, May be they could be included to the existing res area 
-assuming that the path in the east leading out of the village leads to another 
village then, I think, it should be connected with the main path I mentioned 
above even we cannot discern it in the imagery. In such a case I assume a 
„virtual“ path meandering between the houses and connect it to the main path.

I’m mapping also in #2768. Feel free to have a look at the squares in the NE 
edge of the project. Suggestions are always welcome.

Best,

Arne

[HOT] Waterways in swampy area

[Arne Kimmig]

Is it okay to map waterways in swampy areas as canals? See

Re: [HOT] Feedback about the Tasking Manager

[Arne Kimmig]

Hi Florian and all, 

Thanks a lot Florian, I was also thinking about giving a similar feedback for 
the Aweil project. I support Florian's suggestions and below I added some more 
detailed comments about my observations during mapping.

I also think that TM is a great tool and in connection with Josm (I don’t know 
ID) I really enjoy mapping.

Best regards,

Arne


Errors I watched in the Aweil project

-buildings are marked as points and not traced
-buildings are not rounded or rectangular
-buildings get marked and tagged with additional information like 'residential'

-residential areas are drawn for less than three buildings
-residential areas are marked or tagged as building

-tasks are marked as done even if the mapper knows that residential areas are 
missing. Sometimes you find the comment 'did only buildings' or so.
-tasks are marked as done without any comment

Some questions that arose during my mapping in the Aweil project:

- What to do when I'm not sure if the structure is a building or not? Do not 
map it? Map it? Mark it with a fixme=confirm property?
- there are different styles mapping residential areas: some map narrowly 
around the buildings, others map them by clustering tukuls that are not to far 
apart (50m or 100m), and others map  big areas according to fences and 
geophysical borders. I know that there is no easy rule to define but there 
might some recommendations how to do it.
I myself started with narrow areas, then I was clustering somehow by distance 
and now I try to follow geophysical borders and fences.
