Userinterface
This overview image illustrates the main map window, with hazard points in purple and the selected hazard point in red, and the wizard-like sidebar accordion. Unlike TsuDAT 1.0, this proposes anchoring the wave height dialog to the hazard point as a pop-up and, optionally, displaying mouse position as a tooltip rather than a field in the sidebar.
Notes on cartography: The purple/red colors for hazard points are not necessarily a final proposal but serve to indicate that the hazard point colors should be distinct from the source points (ie, sub-faults). Furthermore, the source points should probably not be colored along a red-green ramp as in TsuDAT 1.0, as a full 8% of men are colorblind along this dimension (see Penn State Geo486 and ColorBrewer 2.0 for further resources).
Step 1 is where the user explores the disaggregated hazard (the coloured source zones). The user can select a return period which will colour each hazard point according to its tsunami waveheight for that return period. If the user selects a hazard point the wave height field will be populated for that single hazard point for that return period. This will also generate the disaggregated source zone map coloured according to how much each source contributes to the hazard at that point for that return period.
They also can select a source zone and see which events fit the criteria - events with the specified waveheight at the selected hazard point in the selected source zone. These events populate the event table and give details on their unique ID, probability, wave height, earthquake magnitude, and slip on the fault. The user then selects ONE event which will be run in the tsunami simulation.
Step 2 is where the user defines a polygon that represents the tsunami simulation area. This is done by either importing or drawing a polygon and then defining the mesh resolution. The user then has the option to create internal polygons that define different areas of mesh resolution, mesh friction or areas of interest. The polygons will appear in the table for review.
Here are simulation parameters for such as the initial water level, start and end time, and a mesh smoothing parameter.
Here the user defines some output parameters. These include the area they want the output raster to be generated for - either the whole simulation area or AOI(s) defined in step 1 and the raster resolution. They also specify the layers that will be output for the simulation - these are physical properties from the simulation. The user can also create points within the simulation area that will output timeseries of the tsunami waveheights over the simulation. These can be offshore (elevation=0) or onshore. The user can then choose to save the simulation set up or run the simulation.
The elevation data table shows the elevation data that is available within the simulation area. The user can import their own data as well. They can view the metadata then rank the elevation data sets according to their spatial resolution (finest at top) or accuracy. This will guide the elevation data compliation step which will cookie-cut the elevation data sets to create a single elevation data set.
Initial display window showing the Hazard Points all colored red. Note that no items in the right hand control panel are selected.
The user next selects a Source Zone by drawing a bounding box around the Sub Faults. Only one Source Zone can be selected at a time, so if two or more Source Zones fall within the specified bounding box, a popup asks the user to select which Source Zone to Use.
The Sub Faults constituting the selected Source Zone are now highlighted and the list of events valid for the specified parameters (Hazard Point, Source Zone and Wave Height w/ +/-) are displayed in the Events grid.
A single event is now selected in the Events Grid.
The user next uploads a text file containing a list of points constituting the desired bounding polygon.
The Bounding polygon is now displayed on the interface.
