[Talk-ca] Importing buildings in Canada

[Daniel @jfd553]

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.
