Page History

In the present platform version the available Applications ("Applications" tag in the IS-EPOS main page) are grouped into the categories shown in Figure 1, each one containing several applications (click on each Applications for details):

Figure 1. Applications available in IS-EPOS Platform.

In general, Applications in IS-EPOS can be divided into Data Handling and Data Processing Applications in terms of their outputs. Data Processing Applications sustain advanced methodologies for AH data analysis, whereas Data Handling Applications comprise tools for data transformation and handling. A possible taxonomy of the Data Processing Application is the following. These applications are available after clicking on "'add to workspace" ' panel (right side of Figure 1).

Step 1:Browse Anthropogenic Hazard Episodes by clicking on "AH Episodes" and select a specific Episode from the list by clicking on one of the panels (e.g. the one indicated by the red box in Figure 2):

Figure 2. Episodes list on IS-EPOS Platform.

Step 2: Select a data type from the list (e.g. catalog in the example shown in Figure 3). There are several data types available with respect to the episode and the induced seismicity technology:

Step 3: Once the User selects one data type he obtains access to data attributes, numerical values and visualization applications. For further data processing the User has to click on the "'Actions" ' tab and then on the "'ADD TO WORKSPACE" ' window which appear right below (red frame at the top of Figure 4):

Alternatively, the User may continue from step 2, through the following process:

Step 3b: After selecting an episode the user may receive access to all available data from any episode by clicking on the "'All data related to this episode" ' tab (red box, in the bottom left corner of Figure 5).

Step 3c: A Data search screen is now displayed (See also "'Advanced Data Search" ' in "'AH Episodes" ' chapter). The User may either select one or more (even all) episodes, or apply a filter from the list provided such as time range, country, data type etc (Figure 6).

Step 3d: All  All data after the filtering criteria application is now demonstrated and the User may select one or more data types for further processing. If the User chooses the "View File" tab, the same screen as in the previous step, appears. If the User clicks at the "'Add to Workspace" ' tab, the data is directly transferred to his/hers personal workspace (Figure 7). (See also AH Episodes chapter)

Step 3d: Once the selected data is uploaded at the personal workspace, the User may click on the "'Actions" ' tab in order to use these data in one of the available applications, grouped into 3 categories: "'USE IN APPLICATION"', "'USE IN VISUALIZATION"', "'USE IN SIMPLE COMPONENT"'. This is the Data Oriented Approach shown in Figure 8.

Alternatively, an Application Oriented Approach can be followed as displayed in Figure 9. The User selects the Application first and then clicks on the "'Change input" ' tab for choosing (Shown in the red frame of Figure 9) the appropriate input data file(s).
