Olá, Vitor:<br>
<br>
Some questions:<br>
<br>
Are you going to use any specific software for the import?<br>
<br>
I've opened the rios.shp and hidrografiaInter.shp files, and many<br>
waterways lack any tag, while some have the name. What will be the<br>
tagging schema, for instance to differenciate rivers, streams and<br>
river basins? You should also document the rest of the tags you<br>
propose, like the source tags, and when waterways go underground, for<br>
example.<br>
<br>
Waterways from the dataset aren't adjusted to the objects of the OSM<br>
database. How will you adjust this offset? (it's sometimes 40-50<br>
meters compared against Bing imagery, for example).<br>
<br>
How will be the import process itself? As for what I see from the<br>
data, I think it can't be imported automatically. So how will be the<br>
detailed workflow of it, and how will you solve the different issues?<br>
Very important here will be how you propose to merge that data with<br>
the existing objects in the OSM database, not only with the water<br>
related ones (like Rio Tieté river basin), but also when the river<br>
goes under roads/streets that haven't been tagged with the<br>
bridge+layer tags yet.<br>
<br>
You should also clearly document the changeset tagging for the import,<br>
and the reverse plan, in case something goes wrong.<br>
<br>
Obrigado,<br>
<br>
