ITO Map
ITO Map is a new global slippy overlay map service from ITO World which offers a range of map views to highlight many 'hidden' data layers within OpenStreetMap. It was launched in March 2011 and has had new overlays added a regular intervals since then. It can be used to view existing data within OpenStreetMap and also as a quality assurance tool to help improve the quality and completeness of OpenStreetMap data.
See ITO Map ideas page for details and discussions about additional map layers.
History
ITO Map was released for the UK and parts of northern Europe on 18 March 2011 and was extended to cover the USA, Canada and the Caribbean on the 23 March 2011. It went global on 31 March 2011 with a further four rail related layers added on 7 April 2011. A 'building heights' layer was released on 12 April 2011. Since then new layers have been added. ITO Map was developed by ITO World with support from Ideas in Transit, a five UK government funded research project.
Data updates
The map data is normally updated daily by about 1700UTC for the previous day. On Fridays is takes a bit longer. On occasions an update fails and is missed. After an update all tiles are then freshly rendered from the new data.
Map layers
Below are just some of the map layers available within ITO Map. Check the product itself for the complete current list. You can request new maps or suggest changes to existing maps using the ITO Map ideas wiki page.
Barriers
The barriers overlay highlights a number of different types of barrier=*. Hedges are shown as red, fences as green, walls as blue and central_reservation is light blue. Other types of barrier are currently shown as black.
Buildings and addresses
Shows building=*s as red if there is no associated addressing using addr=* or name=*. Buildings coloured green have a house number using addr:housenumber=*, blue ones have a house name either using name=* or addr:housename=*. Address ranges using addr:interpolation=* are shown as green/blue lines.
Building heights
Showing buildings with height information either encoded using height=* or using building:levels=*.
Car parks
Show area tagged with amenity=parking as shown as blue if there is a capacity=* value and red if not. In this case none of the three cars parks have a capacity given.
Electricity distribution
This view shows electricity lines and the associated voltages. Power lines tagged using power=line are colour black unless there is a voltage=* specified. 400KV lines are coloured blue, 132KV red. low voltage lines using power=minor_line are shown as thin green lines. The voltages are currently designed to suit the UK grid. Additional voltages can be added to the script to accommodate other countries voltages.
Fixme
A view showing ways which are tagged with fixme=*.
Former railways
A view of the 'Former railways' overlay. railway=preserved is shown in green, railway=disused in red, railway=abandoned in blue and railway=dismantled in light purple (not shown in this image).
Green space access
The 'Green space access' layer shows public accessibility to green spaces (see linked article for details).
Layers
The Layer overlay shows ways tagged with layer=*. Layers 2,3,4 and 5 are in shown in orange, layer 1 in red, level 0 in green, level -1 in blue and levels -2, -3 and -4 are in light blue.
Metro
ITO Map Metro overlay shows railway=subway in red.
An ITO Map overlay showing navigable waterways which are tagged with waterway=* and a value of canal, drain, stream or river. If they also have boat=yes they are shown in red and is boat=no are shown in blue; rivers without either are shown in black. The coastline is green, lakes are brown and reservoirs in purple. waterway=riverbank is not displayed to avoid obscuring the colour coding of the river itself.
Railway electrification
Highlighting the data in railway=electrified
Railway engineering
Highlighting bridges (bridge=yes), viaducts (bridge=viaduct), tunnels (tunnel=yes), embankments (embankment=yes)and cuttings (cutting=yes)on mainline railways.
Railway loading gauge
Highlighting the data in railway=loading_gauge
Railway stations
Highlighting station platforms (railway=platform) and if they have a reference (ref=*) defined. Platforms are marked in blue if they have a platform reference and red otherwise.
Railway tracks
Highlighting the number of tracks in railway=tracks. Note that it is generally considered preferable to create a way for each track in which case a twin track line will be shown as two parallel way with tracks=1 rather than one way with tracks=2.
Railways
ITO Map overlay showing railway elements. railway=rail is shown in black. ways with railway=rail and also railway=siding (or yard or spur) are shown in light blue. railway=subway is shown in red, railway=light_rail in blue. The deprecated railway=siding is shown in red. railway=platform are also currently shown in red. railway=narrow_gauge is shown in green.
Schools
ITO Map overlay showing amenity=school. Schools with name=* are shown in blue and red if not.
Speed limits km/h
ITO Map overlay showing the value in maxspeed=* for all ways with highway=* suitable for km/h areas. yellow for maxspeed of 'none'. dark blue for 130/120/110. light blue for 100, purple for 90/80, red for 70/60 orange for 50 and green for 5/10/15/20/30/40. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for road classes of tertiary and higher then roads are shown in black.
Speed limits km/h: major roads
ITO Map overlay showing the value in maxspeed=* for highway=motorway, highway=trunk and highway=primary for areas where speed is shown in km/h. Yellow is used for ways with maxspeed set to 'none', dark blue for 130/120/110, light blue for 100, purple for 90/80, red for 70/60 and orange for 50. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for the above road classes the road is shown in black.
Speed limits mph
ITO Map overlay showing the value in maxspeed=* for all ways with highway=* suitable for areas that used miles per hour. yellow for maxspeed of 'none' (some states in the USA), dark blue for '70 mph' (and '70mph'), light blue for 60/65 mph, purple for 50/55 mph, red for 40/45 mph, orange for 30/35 mph and green for 5/10/15/20/25 mph. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for road classes of tertiary and higher roads are shown in black. Note that speeds much end in 'mph' with an optional but preferred space between the number and the letter 'mph'.
Speed limits mph: major roads
ITO Map overlay showing the value in maxspeed=* for highway=motorway, highway=trunk and highway=primary for area that show speeds as miles per hour. Yellow is used for ways with maxspeed set to 'none' (some states in the USA), dark blue for '70 mph' (and '70mph'), light blue for 60/65 mph, purple for 50/55 mph, red for 40/45 mph and orange for 30/35 mph. Where a maxspeed is set to another value is it shown as 'tan'. If maxspeed is not set then for the above road classes the road is shown in black. Note that speeds much end in 'mph' with an optional but preferred space between the number and the letter 'mph'.
Tracktype
ITO Map overlay showing tracktype=*. Blue is for paved surfaces tracktype=grade1. Black is for paths with an unspecified tracktype.
Unknown roads
Overlay showing unknown roads which are tagged highway=road. After investigation these should be given a more accurate description.
Water
Showing different types of water feature.
