[HOT] [RFC] suggestions for HOT work

Reading though this (and other recent) threads a couple of points I
would like to add as an occasional mapper on HOT tasks.

1. Highlighting of priority or important areas by a co-ordinator would
be nice to have, but not essential.

2. Being able to pick an area, especially next to the one you have
already mapped is (IMO) essential, as there may be features that go
between them that you have partially mapped in the first task, and
would like to continue mapping. Therefore an automated selection
process would be counterproductive IMO.

3. A multi-stage completion process could be useful. For example, if
the most important thing is to map the main roads and residential
areas, these could be completed and the square marked as 'level1
complete' and you could move on to another area. Once most/all of the
areas have the basic items mapped, you (or someone else) could return
and add in supplementary data like buildings, footpaths, land use etc.
I sometimes feel reticent to mark a square as complete if others are
mapping every building but I have not (even if the task is only to add
roads and residential areas). The key part of the task is complete,
but the area is not fully mapped.

4a. I don't know if it would be possible to set up the task with
different sized grids in urban areas. Say for example a 1km grid over
the wider area, but with each 1km square split into 4, 9, or 16
smaller squares in dense areas?

4b. An alternative approach (using existing tools) might be to set up
multiple tasks, with large squares across the region, and separate
subtasks with smaller squares in dense urban areas covering one (or
more) of the large squares. These subtasks could then be marked as a
subtask on the main grid (and shown similar to validated). This could
offer a compromise between ease of implementation and control.

Hope this makes some sense.

regards, Donald
