Re: [Talk-ca] Importing buildings in Canada

In some cases, the aspect ratio is 1:5, creating long vertical tiles (tasks), 
or I may miss something :-)

I've done a number of building imports using no square shapes with no problem. 
JOSM is set to open up new tasks in a separate layer which avoid the problem of 
having task loading next the the just closed task. (I'm doing the imports in 
the US using voting districts. Each district typically has about 200-250 
houses. None of them are ever square. Perfect for an import.)

Best,
Clifford

Bonjour groupe,

I should soon be able to feed the task manager with tiles containing no more 
than 200 buildings each.



I will be using a Quadtree algorithm similar to what was used to split Canvec 
map sheets. The problem is that the algorithm creates tiles that keep the 
aspect ratio of the data bounding box. I am currently modifying the algorithm 
to generate square tiles instead, which is much more adapted for editing with 
JOSM.

if you have data and the extents I can setup tasks(send them to me somehow)

Bonjour groupe,
I should soon be able to feed the task manager with tiles containing no more
