Table of Contents

1. Introduction

This User guide provides general directions for using the Federal Geospatial Data Committee’s National Geospatial Platform (GeoPlatform) for Disasters Resilience. The GeoPlatform is a key component of the United States' National Spatial Data Infrastructure (NSDI), and allows users and communities to post metadata about their critical geospatial assets, thus allowing discovery of those assets by a broad range of users, including the public. These assets include both data and services. The GeoPlatform also allows the creation of communities that can address various challenges and needs. In the case of this pilot, a Disasters Resilience community has been established.

The user guide addresses how a Spatial Data Infrastructure supports the interoperable architecture needed for managing the disaster lifecycle. Users will be shown how to properly support an SDI, the vision for an SDI’s contribution to national disaster lifecycle management, and the critical issues and challenges faced in the use case.

Section 2 presents a high-level architecture of the GeoPlatform and Image Matters SOF4D tool for using data obtained via the GeoPlatform to create GeoPackages for mobile users.

Section 3 will describe in detail the use cases developed for this project.

Section 4 addresses special topics including Right Data for the Right User, Augmented Reality InfoAids, GeoPackage capabilities, and data imagery for the three disasters.

Section 5 describes the three disaster resilience scenarios and the tools used to confront those scenarios.

Section 6 highlights critical data challenges and steps forward.

1.1. Use Case 1: Colombia Rural Wildfire

In 2014, Colombia’s interior and justice minister declared a wave of forest fires affecting a large swath of territory in 12 of the country’s 32 provinces to be a national disaster1. Recurring, widespread wildfires pose a logistical challenge to Colombia’s society and threatens the livelihoods of rural communities. The demo will focus on the rural town of Ciénaga, which supports both agriculture and a coal depot. An emergency response manager will be tasked with assessing information, identifying hazards, and quickly communicating a strategy to first responders.

1.2. Use Case 2: Ghana Suburban Flooding

In 2019, heavy rainfall had been affecting the central coast of Ghana, especially Accra, causing floods. According to media reports, as of 16 April at 8.00 UTC, seven people died in different parts of Accra, four in the suburb of Adjei-Kojo and three in the suburb of Sakaman2. In a simulated flooding event, an emergency response manager will be using topographic, social, and flood inundation data to chart paths for emergency responders to reach stranded civilians.

1.3. Use Case 3: Haiti Urban Hurricane Preparation

Haiti is frequently subjected to hazardous weather conditions that can cause critical damage to local infrastructure and cause loss of life during and after a disaster event. An emergency manager in Port-au-Prince will be using geospatial data to formulate a plan for mitigation and preparedness in the face of an impending hurricane disaster. This plan will be constructed in SOF4D, a fast-response mapping and operational planning web application with GeoPackage capabilities. The emergency manager will outline evacuation routes and triage centers for victims of the event and deploy to disaster preparation teams on the ground.

2. Simple Architecture

2.1. GeoPlatform Architecture

GeoPlatform’s architecture integrates external data gathering with a registry application and web applications for data and metadata visualization.
