HaptoRender/Rendering Rules

This page and the talk page shall help to find a common set of rendering rules for HaptoRender.

Primitive: Node

Group	Tag	Value	Appearance	Remarks
Traffic signals	highway=*	traffic_signals	Proposed: Two holes in a rectangle like the lights of a pedestrian traffic signal (tactile test necessary)
Public Transportation	highway=bus_stop with and without tactile paving	Proposed: Circle on street layer, half on the street, half next to it. Braille abbreviation for name of bus stop (-> Legend)	If tactile_paving=yes then with an embossed circle around on empty space level.
Public Transportation	railway=halt with and without tactile paving	to be definded
POI	amenity=(only most important)	to be defined
Tactile Maps	tourism=information + information=tactile_map	to be defined

Primitive: Way

Group	Tag	Value	Appearance	Remarks
Streets	highway=residential		Deeper than empty space layer. Width = 7mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=tertiary		Deeper than empty space layer. Width = 8mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=secondary		Deeper than empty space layer. Width = 9mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=primary		Deeper than empty space layer. Width = 10mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=service		Deeper than empty space layer. Width = 4.5mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Streets	highway=unclassified	(same as residential)	Deeper than empty space layer. Width = 7mm	If additional lanes=* ist given, 3.5mm per lane. If additional width=* is given, devide value by scale 1:1000.
Railways	railway=track	Embossed dashed line	Width = 3.5 mm	Maybe background layer higher than empty space?

Primitive: Area

Group	Tag, Value	Appearance	Attributes	Remarks
Street: Pedestrian area	highway=pedestrian	On the same layer as streets (deep, -1)	Name: Center name in area in Braille	Texture?
Lake: Landuse = Water	landuse=water	On the same layer as empty space (even, 0)	Name: Center name on textureless back in Braille	Texture: parallel sinus waves of 1 mm width, from west to east

Primitive: Relation

Priority for all Relations: Lowest

Group	Tag	Value	Appearance	Remarks
Routes	Relation Type=Route	Route=Bus

Translation to Braille, Orientation of labels

Object	Tag	Appearance	Remarks
"HaptoRender"
Name of the map (name of the city)
Tile number			to sort the tiles of a tile set
Legend	Name-Tag of different objects (bus_stop)	Not in the map but on extra paper. left column: abbreviation like on the map, right column: name
Braille writing	Different naming tags	Size is fix, height is 6.5mm, TTF: Braille Schirftsatz Blista Marburg	How to write in Braille: (German book for sightes persons) Das System der deutschen Blindenschrift We are going to use Basischrift(=Common letter combinations have their own Braille representation) (nicht Vollschrift(=each black letter is one Braille letter)), as street names are not well presented by Kurzschrift (=Braille-Stenographie).
Coordinates	(Base coordinate)	To identify the position of single tiles in a set of tiles	Center coordinates, decimal, scale (?)

Others

Object	Tag	Appearance	Remarks
"HaptoRender"
Name of the map (name of the city)
Tile number			to sort the tiles of a tile set
Copyright and License	none	"Copyright by (my name, your name) and OpenStreetMap contributors, license cc-by-sa" in Braille and embossed printed latin letters (Arial?)	Maybe cc-by-sa in oval as in the original label?
Compass Rose	(none!)	Wide arrow pointing north (=up) with Braille letter for "n" in the arrowhead (maybe "s" in the end)	Not on each tile?
Legend	Name-Tag of different objects (bus_stop)	Not in the map but on extra paper. left column: abbreviation like on the map, right column: name
Braille writing	Different naming tags	Size is fix, height is 6.5mm, TTF: Braille Schirftsatz Blista Marburg	How to write in Braille: (German book for sightes persons) Das System der deutschen Blindenschrift We are going to use Basischrift(=Common letter combinations have their own Braille representation) (nicht Vollschrift(=each black letter is one Braille letter)), as street names are not well presented by Kurzschrift (=Braille-Stenographie).
Coordinates	(Base coordinate)	To identify the position of single tiles in a set of tiles	Center coordinates, decimal, scale (?)
Scale	(no tag)	Box with a streight line and markers on it, and the value and unit, Braille (like this: +-----------+ 50 m )	Not on each tile? Near Compass rose?
Puzzle connector hole	(no tag)	On each side of the square tile, on the back, there shall be a hole in the base layer, shaped like a circle where 20% of the circle area are cut off at the edge.	Different shapes for NWES? How deep?
Puzzle connector pieces	(no tag)	Need to fit into the puzzle connector holes.	How thick?
