GADEP Toolbox
This page goes over the GADEP toolbox, its tools, and how they work.
The GADEP toolbox contains two script tools:
- Disaster Impact
- Disaster Route Analysis
 |

The Disaster Impact tool is a script (or geoprocessing) tool capable of calculating the disaster impact on one or multiple infrastructures given an earthquake magnitude.
 |

| Figure 2: Disaster Impact tool |
This tool takes in two different parameters:
- Feature Layer
- Earthquake Magnitude
The Feature Layer parameter will take in one or multiple different feature classes present only in the Infrastructures geodatabase. Feature classes in this geodatabase are compatible with the Fragility Database, meaning they will already contain the fields and values necessary to be used in this tool. Learn more about what makes a feature class compatible with the Fragility Database and this tool in the Preparation For Disaster Impact tool page.
This parameter will contain two different dropdown arrows to select the infrastructures you want to use in this tool.
 |
|---|
| Figure 3: Feature Layer dropdown arrows |
To select one or multiple infrastructures:
- Click on one of the dropdowns (preferably the top one; it allows multi-select)
- Make your selection(s) (or select the Toggle All Checkboxes option to select all)
- Click Add

The feature classes will be added to the parameter as a list.

The Earthquake Magnitude parameter has a dropdown arrow which will reveal four different options:

Every earthquake magnitude produces different data and variables that are going to be used in our calculations. For this project, our data was limited to these four magnitudes.
Make your selection by clicking on it.

To run the tool, click on the Run button.

When the tool is running, click on View Details to view the tool's progress.

As the tool runs, messages are printed out as significant sections in the code are reached. In this case, we can see the messages in Figure 10 stating that the simulation for each infrastructure was successful (meaning that the calculations were performed successfully).
To see the results of the calculations on the map, we can click on the refresh button located on the lower right side of the map.

The infrastructures we chose in our Feature Layer parameter will update their colors according to their Damage legend.
 |
 |
|---|---|
| Figure 12: Damage legend for bridges | Figure 13: Bridges damage results |
Clicking on one of these points will produce a pop-up window describing its attributes, including the damage state, the EP value, and the earthquake magnitude selected.
 |

| Figure 14: Bridge pop-up |
These values will be updated for every infrastructure selected in the Feature Layer parameter.
As a result, we have a tool capable of knowing what kind of damage to expect on specific infrastructures after an earthquake.
The Disaster Route Analysis tool is a script (or geoprocessing) tool capable of finding optimal routes between two different sets of points while avoiding any bridges that are too badly damaged.
