Damage Assessment Mapping Module

From WikiNET

The Damage Assessment Mapping Module (DAMM) for Portland NET provides volunteer responders with a tool to document and map impacts of a disaster, and electronically transmit that information to the Portland Emergency Coordination Center (ECC). It is, essentially, an electronic version of NET Form 1 for damage assessment. ECC personnel can immediately use information sent to them from DAMM to allocate resources for response and recovery. Volunteers can document assessments with the DAMM even in the absence of internet service, though internet service is required to transmit the reports completed by a user.

Every NET volunteer and ATV with a smartphone should download the software onto their device and know how to use it in the field.

Program Overview

The Damage Assessment Mapping Module (DAMM) is one of the most important communication tools available to NET volunteers. The tool promotes accuracy, consistency, and efficiency in collecting post-disaster data for use in high-level decision making.

Observations inputted to the DAMM via the Survey123 app are relayed to an Operational Dashboard (fig. 1) displayed to emergency response planners in Portland’s Emergency Coordination Center (ECC). In turn, ECC personnel will use the data to assemble a highly detailed situational awareness picture and allocate response resources accordingly and (where possible) expeditiously. Data inputted to the DAMM will also be critical for applying for federal relief aid and other resources in the aftermath of a major disaster.

Practical DAMM applications in a disaster

The DAMM is set up for volunteers to perform a site-to-site assessment, with one survey submitted per site. While this assessment method is labor intensive, it is highly accurate and used when a higher degree of confidence in the information is required. PBEM recommends that planned use of the DAMM appear in all NET Operations Plans with a Team Leader assigning at least one or two volunteers to begin making reports with it after the acute phase of disaster response has passed (probably 24 hours after an earthquake, for example). Volunteers using the DAMM assess each property site in their neighborhood, site by site, and reports should include undamaged property (in the survey, there is an option to indicate up front that a volunteer observes no damage).

Who is allowed to use the DAMM?

NET and COAD volunteers above all others. But, NET and COAD volunteers can also “deputize” spontaneous volunteers as needed. In the survey, a deputized spontaneous volunteer should use their own name but the badge number of the volunteer who deputized them.

DAMM Form Fields

 
Figure 2: Different types of DAMM field. Click to enlarge.

The field structure and interface of the DAMM is designed for quick and detailed reporting. Though the number of fields might intimidate a new user, note that most of them are "selection" fields which often require no more than a "yes" or "no", with one answer already selected as a default. With practice, a typical volunteer will complete a single site report in only a few minutes.

The table below lists each of the reporting fields, broken up into sections such as "Site Details" or "Damage Details". The fields are not numbered in the DAMM, but numbered in this article for easy reference. Most fields do not require a response; the ones that do are indicated with a checkmark in the table. Each field has a "type", indicating the type of information to input (Fig. 2). The more common ones are:

  • Selection, presented as a series of radio buttons, and the user can only choose one of the given options.
  • Checkboxes are similar to Selection radio buttons; but, a user can select multiple checkboxes.
  • Text is a text field the user can type in to. Though text can paint a more detailed picture, text boxes appear rarely because typing slows down a responding user.
  • Integer is a field with +/- buttons so a user can quickly input a number.

The "Notes" column includes selection options and special attributes, if any, of a field.

Taking a Photo in DAMM

One key step to good incident observation is taking photographs of the scene. The photos are one of the best ways to demonstrate the extent of damage sustained from an incident. Incident commanders, insurance adjusters, FEMA representatives, and property owners will all get a better idea of conditions with photographs. Keep in mind that you are simply trying to preserve evidence, not win photography awards. The built-in camera from your mobile device will capture details. Also, the built-in watermark will add a timestamp and detailed location to each photo that will link your photos to the location.

How to take a photo in DAMM

  1. Activate the camera: Pressing the camera icon button will activate the camera of your mobile device.
  2. Taking the picture: Point your mobile device at the subject you wish to report (i.e. fire, damage to building, fallen tree) and press the photo button. Note the style of the icons will vary based on phone model.  Take photos in horizontal orientation with good Lighting.
  3. Additional photos: After taking a photo, an icon will appear that allows you to take an additional photo. The system allows for a maximum of three (3) photos for each report. Example uses for additional photos:
    • Multiple incidents at a single observation point (i.e. fire and structural damage);
    • A different angle of the same incident;
    • Thorough documentation of damage.
  4. Watermark: For documentation purposes, the system will automatically embed each photo with the following:
    • Site address (top left, line 1)
    • Latitude/Longitude (top left, line 2)
    • Observer name (bottom right, line 1)
    • NET Team (bottom right, line 1)
    • Badge number (bottom right, line 1)
    • Date and time, 24 hour format (bottom right, line 2)

What to consider when taking a site photo

Capture the details

When thinking about what to photograph, it may not be obvious which details will become important later on. Generally, the more pictures you take, the better. However, the DAMM only allows for three photos to send with each report, so choose your photographs carefully.

Take pictures of:

  • The structure and damage sustained;
  • Other structures at the address, and the damage they sustained;
  • The overall site (i.e., the intersection, parking lot, or other location);
  • The environment/weather conditions; and
  • Any visible bodily injuries (if feasible and consented to).
Take photos from different angles and distances

It's best to take a wide variety of photos. Snap photographs from at least three different angles and distances. For close-up photographs, take the picture from one to five feet from the subject. Also take medium distance photographs (from 10 to 15 feet away) and long distance or panoramic photographs (from 20 or more feet away) when it is safe and makes sense to do so.

When taking pictures of the surrounding area, try to keep a common landmark in each of the photographs to demonstrate distance and scale. Also be aware of sunlight and weather conditions and how those might affect your photographs, especially those relating to damage. If possible, use different flash intensities, and/or take the same photographs with and without flash.
