Data Intake and Discovery

The following tutorial demonstrates basic functions of the DID for data curation and querying, with more detailed guidance provided in the User Manual. Within the DID Dashboard, the Options tab allows the user to input data through one of two modalities: manual report creation (suitable for users supplying a small number of reports) or database upload using comma separated values (CSV) (more appropriate for users with a large number of reports). The former is demonstrated herein, while the latter is described fully in the User Manual.

  1. User supplies inputs for selected fields, clicking on the Set Geometry with Map button to launch a dynamic map for the user to pin the location of the survey in the case that exact coordinates were not known. After submitting the form, the user can add an arbitrary number of key-value pairs as searchable metadata.

  2. The user can use the DID Dashboard to view not only their submitted damage reports, but also those from other researchers as well as field observations. The DID Dashboard has five different widgets, which can be resized and rearranged into any configuration as desired by the user. The Warehouse Reports Filter allows the user to search for reports, filtering results based on field, filter type, and filter value. A range of both standard filters (e.g., contains, ends with, is exactly, is less than) as well as spatial filters (e.g., bounding box contains, bounding box overlaps with) are available. Users can use the plus button to add as many search constraints as desired. The user then specifies how to view results, e.g., in ascending or descending order by various attributes such as report title, event date, or event type.
  3. The Warehouse Reports List widget is then responsible for displaying reports from the Filter widget in a tabular fashion. Results are paginated and users can move between pages with the controls at the bottom of the widget. By clicking on the title of any report in the Warehouse Reports List widget, the report is loaded into the Warehouse Reports Detail widget and the Warehouse Reports Map will dynamically focus on the location of this report. Users can achieve the same outcome by directly clicking on a report pin in the Warehouse Reports Map.

  4. Users can further refine the search using a joint standard and spatial search to identify damage reports within a specific geographic area. Users can also check multiple reports in the Warehouse Reports List and apply different actions from the drop down at the top of this widget (batch addition of metadata or exporting this bundle of reports to a single PDF).  By selecting a specific report, the full report is displayed in the Warehouse Reports Detail, including geotagged images. The Warehouse Reports Detail also allows users to edit/add metadata key-value pairs to the report at any point in its life cycle to further enhance data discovery through query. From this widget users can also help maintain the accuracy of this communal database by flagging reports that are duplicates, contain inappropriate content, are incomplete or are inaccurate.
