Trailblazer

An interactive desktop map that can help you find the shortest path between two intersections.

Build

This project uses Maven.

mvn package

Run

mvn exec:java -Dexec.args="FILE [--directions START END] [--show]"

where:

• FILE is the file that contains the map data;
• START is the ID of the start intersection;
• END is the ID of the end intersection.

Controls

• Mouse drag to drag the map
• Mouse scroll to zoom in and out
• Ctrl + mouse drag to rotate the map

Available data

Data is fetched from the data folder. Currently, the following maps are available:

• ur.txt: The University of Rochester's pedestrian walkside data;
• monroe.txt: The Monroe county in the state of New York;
• nys.txt: The entire state of New York (including Long Island!)

Data is from OpenStreetMap.

Examples

mvn exec:java -Dexec.args="data/ur.txt --directions SUEB HOYT --show"

…shows UR freshmen how to get from their dorm to Hoyt auditorium (where the intro CS class usually takes place)!

The command line output shows the intersections one has to take:

Going from SUEB to HOYT
SUEB
UHS
i76
i60
i55
i42
MOREY
i45
HOYT
Total miles travelled: 0.23207491657297358

Here are some more examples.

mvn exec:java -Dexec.args="data/monroe.txt --show"

…shows the Monroe county.

mvn exec:java -Dexec.args="data/nys.txt --directions i102030 i80549 --show"

…shows how to get from the very West of the NY state all the way to Long Island in 3 seconds! FWIW, this map has 389818 intersections.

To-do

• Show raster tiles instead of drawing the roads (WIP!)
• Create panels for GUI controls
  • Allow users to enter locations based on longtitude/latitude or human address
  • Allow users to switch between maps
• Fetch XML from OpenStreetMap and parse for data
