Some task suggestions

Here are some tasks this project could work on:

  • Brazilian Federal nature reserves and indigenous lands are completely mapped. The next step is to map state-owned nature reserves. WikiProject Brazil/Unidades de conservação gives one approach to that.
  • There are some very large "natural=wood" polygons in the map (examples: way 192956700, way 185481723). Those are very likely to be imprecise (for exemple, there must be some roads, villages and rivers inside them) so they should be revised and perhaps deleted.

Also, when mapping a river which serves as administrative boundary (or boundary of a protected area), it is important to remember to replace exisiting administrative bondary by the new river geometry.

Highway: unclassified vs track vs path

The wiki says the following:

  • highway=unclassified: public, non-residential ways that are less important than tertiary roads
  • highway=path: non-motorized ways with unspecified usage (the mapper doesn't know what it is intended for) or with multiple primary uses (two or more uses are recognized but none can be said to be the main intent of the path, eg.: combined footway and cycleway)
  • highway=track: private ways in farms and managed forests

Many of those qualities are not apparent from satellite imagery. If very uncertain, use path. There may be a few farms, and forests in nature reserves can be said to be managed. Elsewhere, the Amazon rainforest is not managed, so tracks would be nonexistent there. The distinction between unclassified and path can initially be approximated based on the path's width (at least 3 meters wide for motor vehicles). This will be incorrect sometimes, but I think it is safe to assume future ground surveyors will fix that. --Fernando Trebien (talk) 12:16, 17 December 2017 (UTC)
