[Talk-ca] Importing buildings in Canada

[Daniel @jfd553]

I think it is desirable to stay close to a KISS (Keep It Simple and Stupid) approach for editing data. I have doubts about the need to ensure that a building will not be edited twice, or about the advantages of changing the angles in the task manager. However, as long as the import process does not become tedious or complex, I have no objections.

Yeah, there are issues with the Toronto Simplification tasks ... I was tempted to orient the task grid more to the actual streets by rotating everything ~17 degrees. The problem with that is that when downloading the task data by bounding box (i.e. a new unrotated bounding box) you end up getting lots of data that's not in the task. I've found that the best way to do the validation tasks is to download the task data and then download a slightly expanded bounding box to ensure I have everything. Not the cleanest solution, but it's the best I've found so far.

Arbitrary task shapes seem to work fine for importing though because you can easily see where the new data starts and ends. And buildings can be assigned to a task uniquely without difficulty.

Bonjour Nate,

Cette approche avec taille et forme variable des tâches est intéressante pour contrôler le nombre de bâtiments à valider.  Pour éviter les conflits d'édition, est-t-il possible de s'assurer qu'un bâtiment se retrouvera dans une seule tâche ?

Si des bâtiments se retrouvent sur la ligne de contour de la tâche, il seront sélectionnés dans deux tâches différentes. Voir par exemple http://tasks.osmcanada.ca/project/168#task/152

Une façon d'éviter cela serait de s'aligner le plus possible sur les routes.

The task size, and even shape is totally customizable. I've set up a couple that are entirely based on the density of the data:
