1. Development of a Tactile Map Automated Creation System Using OpenStreetMap Data *1 *1 *2 *1 Graduate School of Science and Technology University of Niigata *2 Faculty of Engineering, University of Niigata Implementation of a Contents Change Function According to the Scale ◦Chiharu BABA ◦Toshimitsu YAMAGUCHI ◦Tetsuya WATANABE 1
2. Importance of maps • Know unfamiliar places • Know uncertain places • Recall the routes • etc. 2 The same roles apply to blind persons OSM of Tsurugajo Castle
3. What is tactile map Tactile maps support blind people • Orientation • Navigation 3
4. When using swell paper Swell paper Need monochrome drawings of maps 4
5. How monochrome image is created Step 1. Download a map image Step 2. Trace roads in black (with drawing software) Step 3. Put tactile patterns and symbols 5
6. Problems in making tactile maps 6 Takes much time and effort Needs technical knowledge Need for tactile map automated creation system
7. Tactile Map Automated Creation System (TMACS) for OpenStreetMap 7
8. System overview System category: Web application How to use: 1. Search for a place by address 2. Move and zoom the map 8 System top page
9. Top page OSM map object Tactile map image Setting panel 9 Settings Location Base map Opacity of the base map Search OFF
10. System block diagram Top page (HTML) JavaScript Mapfile ① MapServer ③ Web API Map data (OSM data) ② Sever Client Google Maps API (Geocording) OpenLayers (Display Map) OpenStreetMap (Map Object) 10
11. Conversion of OSM data Convert OSM data to GIS database by osm2pgsql 11 Download site DB OSM file (XML format) osm2pgsql
12. Characteristics of the system 1. Maps can contain information useful for blind people 2. Wide area images are readable by touch 12
13. Characteristics 1 Maps can contain information useful for blind people 13 By using OSM data
14. Information useful for blind pedestrians • Tactile paving • Obstruction • Signal with sound • Change of the sidewalk surface 14 OpenStreetMap General map data
15. Merits of using OSM data 1. Arbitrary information can be registered － such as tactile pavement 2. Covers the globe 3. Free 15
16. Map features Key Value Tactile pavement tactile_ paving yes Obstructions barrier block bollard cycle_barrier Data useful for blind people 16
17. Characteristics 2 Wide area images are readable by touch 17
18. Wide area images 18 Select roads to display according to the scale A gap of at least 3 mm between the roads is necessary Too many objects
19. Tactile symbols 19 Type of symbols Objects Images Line Road Huge Large Normal Small Road with tactile paving Railway River Area Water area Station Point Traffic signals Obstacle
20. Select roads to display Road type 1/2500 1/5000 1/10000 Huge ◦ ◦ ◦ Large ◦ ◦ ◦ Normal ◦ ◦ ― Small ◦ ― ― ※ Other objects are displayed in all scales 20
21. Select roads to display Road type 1/2500 1/5000 1/10000 Huge ◦ ◦ ◦ Large ◦ ◦ ◦ Normal ◦ ◦ ― Small ◦ ― ― ※ Other objects are displayed in all scales 21
22. Select roads to display Road type 1/2500 1/5000 1/10000 Huge ◦ ◦ ◦ Large ◦ ◦ ◦ Normal ◦ ◦ ― Small ◦ ― ― ※ Other objects are displayed in all scales 22
23. How to use the system 23
25. How to use the system 25
26. Tactile map image 1 Station Rail Water area Signal Road 26
27. Tactile map image 2 Tactile paving Obstruction 27
28. Future work 28
29. Add more information on the tactile map Less key:tactile_paving and key:barrier is registered 29 More data useful for blind people
30. Add entrance symbols on the tactile map 30 More key:entrance! Blind people hardly find an entrance ? ? ? ?
31. Classify roads by width MAPPLE 10000 OSM data New system Old system 2mm 3mm 31 Add width data at roads
32. Create a map wherever user needs More object data at all area evenly Rural area have only poor data OSM Google Map
33. Every little helps! 33
