Emergency and Disaster Management

Domain Working Group

The mission of the Emergency and Disaster Management (EDM) Domain Working Group (DWG) is to enhance the efficiency and effectiveness of users engaged in all stages of emergency and disaster activities. This group facilitates modifications and extensions to OGC Standards, resulting in geospatial products and other information resources that can be shared across communities in an interoperable manner.

The Emergency and Disaster Management (EDM) Domain Working Group (DWG) is committed to enhancing the efficiency and effectiveness of users engaged in all phases of emergency and disaster activities. This mission is achieved by refining and expanding Open Geospatial Consortium (OGC) Standards, resulting in interoperable geospatial products and other information resources that can be seamlessly exchanged across these communities.

The EDM DWG is formed through the merger of the Law Enforcement and Public Safety DWG and the Emergency and Disaster Management DWG. Its ultimate charter is pending approval, but it is driven by the purpose of promoting and supporting the establishment of requirements and best practices for web service interfaces, models, and schemas. These enable the comprehensive handling of information, fostering improved discovery, access, sharing, analysis, visualization, and processing. The focus extends to activities related to forecasting, prevention, response, and recovery from emergency and disaster situations.

Key objectives of the EDM DWG include unifying communities of users encompassing government agencies, industry, research organizations, and non-government organizations across various emergency and disaster activity phases. The group serves as a platform to discuss interoperability and standards requirements, with topics ranging from events of different scales to situations with limited communication capabilities. It evaluates input against existing standards and architecture, identifying interoperability gaps and opportunities to enhance information sharing and collaboration. The EDM DWG collaborates closely with other OGC Technical Committee activities, developing new requirements and change requests.

This DWG aligns with the mission to drive open geospatial standards and products that support improved decision-making and operational efficiencies. It aims to foster domain-specific collaboration, identify requirements and gaps, and promote best practices. The membership of the EDM DWG is open to OGC members and organizations interested in contributing to interoperability goals. Its governance adheres to OGC Technical Committee Policies and Procedures.

The purpose of the Law Enforcement and Public Safety (LEAPS) DWG is to establish requirements and best practices for web service interfaces, data models, and schemas. This supports comprehensive addressing of crime, terrorism, and public safety incidents. The LEAPS DWG covers all phases of GIS-enabled law enforcement, civil security, and public safety activities. It fosters collaboration between various stakeholders, and its objectives include driving domain requirements, promoting collaboration, and educating users and technology providers.

Overall, both the EDM and LEAPS DWGs contribute to advancing geospatial solutions for emergency and disaster management and law enforcement, respectively. Their efforts aim to ensure interoperability, data sharing, and effective decision-making in critical domains.

The EDM DWG reviews the deliverables from COSI Disaster Pilots. The graphic above demonstrates how to account for the distinct time and space scales of management and response, recognizing the significant variations across different hazards, such as flood events spanning hours to minutes and drought conditions extending from days to years.

OGC Discussion Papers must be submitted for approval by the DWG. This paper explores the applicability of yellow and red warning publishing rules using the disaster early-warning mechanism for debris flows and large-scale landslides established by the Soil and Water Conservation Bureau (SWCB) in Taiwan.

Tien-Yin (Jimmy) Chou is a co-chair of the EDM DWG. Dr. Chou earned his doctoral degree from Michigan State University’s Department of Resources Development in 1990. For two decades, he has directed Feng Chia University’s Geographic Information Systems (GIS) Research Center. As a Distinguished Professor in the Departments of Urban Planning and Spatial Information and Land Management, Prof. Chou, along with his dedicated team of 150 staff members, has significantly advanced GIS.FCU’s standing in domestic and global GIS-related academia and industry. His leadership has propelled research and projects spanning data infrastructure, security, resources management, UAVs, smart cities, cloud computing, and more. Prof. Chou also guides graduate students and teaches GIS science, land management, and resources management at FCU.
