[OSM-talk] to all potlatch and JOSM users - automatic simplification of geometry

[Richard Fairhurst]

Martin and I have had this conversation on private e-mail too, but one point
bears repeating:

> I know that some people like this tidy-points-function to 
> work on TIGER-Data, but I tell you: if the TIGER-Data is

That is evidently not true.

Find a grid system - almost any US city will do. Look at the TIGER data. It
weaves and waves all over the place.

Turn on the Yahoo imagery, align the start and end points of the way, and
select the 'Tidy' function. Hey presto, the street is now correctly aligned
to the grid. You could have done this manually, but it would have taken 10
times as long and wouldn't be as precise.

_That_ is why this function is here: to simplify the work of one of the most
tedious parts of TIGER fixup. As always, "it's of no use for my mapping"
should not be extrapolated to "it's of no use and should be banned".

cheers
Richard
