Roads

Neighborhood grid

Residential buildings are usually located on a residential or living_street and has access to a road only on one side, and optionally on the backside via a service alleyway. A building with residential roads on multiple sides is a sign of mistaking building shadows for streets. The street grid in an an area will have repeating patterns that make it easy to guess how the roads are laid even if they are obscured by trees.

Using Fast draw plugin

• Install and use Fast draw plugin (shift + F).
• Press down arrow to simplify way, up arrow to add more complexity and then Enter.
• Q to simplify straight segments of roads.
• Shortcuts to tag each type of road classification Preferences > Customize the icons in the toolbar > Presets > highways/ features that require shortcut > highways/streets > select the road you want to add as shortcut > right click on the shortcut and add a shortcut.

Buildings

• Parallel buildings can be traced using the building tools plugin (B). Select a building and using the tool align subsequent buildings to the first one in one step.

• You can use the Area extrude tool (x), to quickly add details to the outlines by creating new nodes (double click) and then dragging the faces.

• Compound buildings To combine overlapping buildings, select both building and click Join overlapping Areas (Shift + J). For several intersecting buildings, use I > Shift+J. Or, use the Auto Tools > Combine LA buildings.

• In Extrusion mode (X), do Ctrl + Cmd to redraw/reshape buildings for irregularly shaped buildings.

• In Extrusion mode (X), add four nodes in a segment, hold the Ctrl + Cmd key, and drag the middle segment to create pyramidal extrusions.

• Double tap A to draw buildings with irregular sized extrusions. Or create several smaller buildings

• For buildings sharing the same wall, draw buildings (B) and, select intersecting node and click Join Node to a Way (J) or Move Node unto Way (N).

• To split a single building into two, select two nodes and select Split Object (Alt + X)

• Use Terracer plugin for multiple same shaped buildings sharing the same wall (Shift + T)

• For circular features, draw the diameter, select the way, and click Tools > Create Circle (Shift + O).

• Use Resize tool (Ctrl + Alt) to re-size shape.

Others

Individual parking spaces

Draw a box enclosing the parking spaces and use the terracer plugin to create a grid. Replace the default building=yes tag with amenity=parking_space. If you created adjacent grids, you would want to use the validator to automatically merge the overlapping nodes.

Tagging driveway through a building

Relevant tagging option for building would be

building=roof and layer=1

Highway road under the roof tagging options

covered=yes
highway=footway
highway=residential
highway=service

Tagging stadium tracks

Relevant tagging option for Stadium would be

• trace centerline of track as line (leisure=track;area=no)
• connect centerlines with surrounding foot paths or streets where possible
