Linux Tool for Geographic Graphs

Just another C++ hack

Requirements

Following programs are required to build:

• gcc >= 4.7 with C++11 support
• OpenSceneGraph >= 3.3.3 (binaries included)
• osgEarth >= 2.6.0 (binaries included)

Usage scenarios

• Simple selection functionalities for geographic maps
• Quick & dirty geo-coordinate processing/visualization

Shortcuts

Switching operation modes

• Enter the Selection Mode with F2 (load/erase/save graph selections)
• Enter the Turn Processing Mode with F3(process road turns)

Selecting graph parts

• Draw a bounding box: in the Selection Mode, click at two map points with the left mouse button. One point is the bottom-left and the other is the top-right.
• Draw an arbitrary polygon: in the Selection Mode, hold Shift and click at multiple screeen points with the left mouse button to form the polygon corners. To close the polygon and finish the polygon marking, perform a last click with the right mouse button.
• Erase a selection polygon: in the Selection Mode, hold Ctrl and click over a geometric form. The polygon containing the center point which is the nearest to the clicked point will be deleted.

Managing pins

• Stick a pin: in the Selection Mode click at the wished map point with the right mouse button.
• Change the pin color: out of any mode, press Shift and click over a pin.

Managing graph nodes/edges

• Stepwise drawing nodes: F5 (number of nodes per round is hardcoded)
• Stepwise drawing edges: F6 (number of nodes per round is hardcoded)
• Save selected graph nodes in a .CO file: F7 (directory is hardcoded)
• Save selected graph edges in a .GR file: F8 (directory is hardcoded)

Geo-coordinate membership tests

• Check whether a cliked point belongs to a geometric form: in the Turn Processing Mode, hold Shift and click at any map point with the mouse right button.

Compilation

$ make

Running

(1) ./run.sh (should work in most Linux systems, if the code is cloned in the home directory with all dependencies)

TODOs

(1) Include some Qt stuff, like boxes for providing the output file name or a combo box for selecting the graphs to be processed, so that not all the graphs must be loaded at once

(2) Actualize the dependencies
