Transcript Monkey Map
A Mobile Map Service Project Kilo 2004 Introduction Location-finding service and mapping system Users can ask for directions to advertising clients Graphical web interface (Java applet on website) Text-based mobile phone interface (WAP pages) 1 Java Client www.monkeymap.tk 2 WAP Client Dynamically created text-based menu system Language selection Transport type Source selection 3 WAP Client Destination selection Instruction display WAP URL is on the website 4 System Overview Web Site 5 Renderer Applet Server Mobile Phone Map Data HTTP Router Instruction Generator Data And Maps Data is entered by map coordinates, based on the Cambridge University Map for this dataset Primary data format: Text file for simple entry Road = chain of Nodes perl script Secondary data format: XML file for server Directed graph of Nodes 6 Data And Maps Server parses XML, performing verification Map data loaded into internal data structures Server loads building images from SVG (Scalable Vector Graphics) file Separation of server and client data 7 Server Architecture Runs as a Java Servlet, using the Apache Tomcat webserver All communication via HTTP Decodes applet requests, and calls appropriate methods on the server Directs WAP requests to the WML generator 8 Route Finding Uses the A-Star algorithm to efficiently find the shortest path on the map Ability to find the shortest route to a category Intuitive instruction generation (in multiple languages) with time estimates Recent routes are cached 9 Map Rendering Roads are dynamically rendered from XML data Uses SVG and the Apache Batik libraries Two layers of image caching for significant performance improvement 10 And the future…? 11 Has the potential for substantially increased map data Response times indicate high level of scalability Tools for automating data entry could be built from the applet Conclusions 12 We have successfully integrated a wide range of technologies Monkey Map is a working product that is of use to a wide range of people Good design leads to easier implementation!
