EmerGeo Integrates Hazardous Material Models into OpenGIS Emergency Mapping Software

EmerGeo’s ALOHA and ERG2004 mapping interfaces give responders rapid, real-time modeling and reporting for chemical plumes and the people and infrastructure affected.

VANCOUVER, B.C., November 15, 2004 – EmerGeo Solutions Inc., a developer of OpenGIS based mapping solutions for emergency managers and major event security planners, today announced additional mapping tools to enhance preparedness and response capabilities. EmerGeo emergency mapping software is based on interoperable OpenGIS and web mapping technologies to manage and distribute information about an incident or event to those who need it. Today’s announcement adds chemical dispersion models to EmerGeo’s natural hazard models to support all-hazard planning and response.

ALOHA® Plume Model Interface
ALOHA® (Areal Locations of Hazardous Atmospheres) is an atmospheric dispersion model that is widely used for evaluating releases of hazardous chemical vapors. It is developed by EPA’s Chemical Emergency Preparedness and Prevention Office (CEPPO) and the National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA). ALOHA gives users an estimate of the downwind dispersion of a chemical cloud based on the toxicological/physical characteristics of the released chemical, atmospheric conditions (including real-time meteorological data inputs), and specific circumstances of the release. Graphical outputs include a “cloud footprint” that can be automatically plotted on EmerGeo maps. EmerGeo can use customer’s existing GIS map data, or third-party map data, to display the location of hazards and vulnerabilities that may be impacted by a toxic release, such as hospitals, schools, shelters and other critical infrastructure. Analytical tools (spatial query function) in EmerGeo generate quick reports of what lies within or within distance of (buffer zone) the plume. These reports can be exported to Microsoft Excel for graphing or additional reporting. Specific information about each location or area can be extracted from EmerGeo through simple ‘hotlinks’, such as chemical inventories, emergency plans, or company web pages, to help make better decisions and respond more effectively.

Emergency Response Guidebook Interface

The Emergency Response Guidebook (ERG2004) was developed jointly by the US Department of Transportation, Transport Canada, and the Secretariat of Communications and Transportation of Mexico (SCT) for use by firefighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving a hazardous material. It is primarily a guide to aid first responders in (1) quickly identifying the specific or generic classification of the material(s) involved in the incident, and (2) protecting themselves and the general public during this initial response phase of the incident. EmerGeo’s ERG2004 Hazard Model allows users to rapidly produce maps of isolation and protection areas based on the ERG2004 chemical list and guidelines.

EmerGeo’s OpenGIS® data connectors enable users to work with their own GIS data, regardless of whether they use ESRI, Intergraph, MapInfo, AutoDesk or other OpenGIS® compliant GIS mapping system(s). The application can also run on mobile PC’s, allowing first responders to selectively publish model outputs, drawings and other data layers to other individuals and groups with an EmerGeo Smart Client or just a web browser.
