Disaster events often present broad, swiftly changing geographic impacts. Emergency management operations fundamentally depend on geospatial technologies to successfully respond to these situations. Rapidly authoring, fusing, managing, and delivering data is crucial for up-to-date situational awareness and response and recovery efforts. However, the effectiveness of those efforts can be directly correlated to the proactive planning your municipality engages in before disaster strikes.
Now, using ERDAS IMAGINE, ERDAS APOLLO, and GeoMedia solutions from Intergraph, a broader group of individuals and departments across your municipality can create data, maps, and reports to more efficiently perform their proactive disaster planning tasks, all the while communicating and working collaboratively across departmental boundaries.
Additionally, crowdsourcing data about city infrastructure is a new technique being used by forward-looking municipalities. Intergraph’s Mobile Alert, a cloud-based service that delivers crowd sourced incident information, can be made available to citizens as a free iOS or Android app that allows them to report issues. Municipalities can subscribe to receive the input by e-mail or through portals using the Open Geospatial Consortium web services. You can also decide whether you’d like to add the public’s data into your in-house solutions.
Take, for example, the disaster planning model currently used by many coastal cities concerned with flooding from storm surges. Most coastal communities rely on The Sea, Lake, and Overland Surges from Hurricanes (SLOSH). SLOSH is a computerized numerical model developed by the National Weather Service to estimate storm surges, based on a combination of historical and current storm data. It is a good starting point, but municipalities really need to combine that information with a complete view of the geospatial data they may already have on hand, and create precise 3D maps of the entire area for which they have responsibility.
Municipalities can now augment models such as SLOSH by implementing Intergraph geospatial solutions. City planners can use accurately processed imagery and terrain data from ERDAS IMAGINE to update attributes in GIS and CAD files. They can deliver and distribute that geospatial information via a cloud-based ERDAS APOLLO 2013 portal, and leverage GeoMedia to visualize Digital Elevation Models (DEM) using its comprehensive toolset for managing and analyzing geospatial data. Our ERDAS IMAGINE Spatial Modeler allows you to modify SLOSH models, as well as create and incorporate additional models for scenario-type analysis.
For disaster planning operations, Intergraph geospatial solutions improve staff collaboration and communication while lowering cost of ownership for geospatial solutions. Municipal management workflows, such as disaster planning, provide city departments with productive tools to proactively design evacuation and recovery actions.
GeoMedia helps municipalities achieve these goals by bringing the benefits of a powerful GIS to everyone in the organization. With that sort of precise spatial intelligence at their fingertips, officials can more accurately predict flooding impacts (for example) when a storm is coming, just how many residents will be affected, drilling down to the threat in a particular neighborhood, or even a sub-neighborhood. In addition, GeoMedia Smart Client helps municipalities achieve these goals by enabling geospatial business workflows across the organization. It delivers a disaster planning solution with highly configurable rules, dynamic life-cycle workflows, feature-level access control, data validation and behavior, and easy integration with other systems.
Municipalities can use GeoMedia to simulate the impact of a given storm on city properties such as schools and parks. The information contained within GeoMedia can be as obvious as whether a particular parcel will be flooded, and as granular as how many times and to what degree that particular parcel was impacted in prior disaster events. The result – a geospatially enabled understanding of every parcel of city and privately owned land – enhances proactive planning efforts and drives efficiency.
Effective disaster planning relies on thorough integration of emergency plans at all levels of government. The combination of GeoMedia and Oracle Spatial enterprise database includes advantages such as real-time access to spatial data across the enterprise. It also delivers secure data in a universal format for viewing and updating spatial data. This promotes better information sharing, coordination, and reuse, while preventing inefficiencies, errors, and risks that arise when departments work in data silos.
GeoMedia enables individual users with proper, secure access to instantly update geospatial information, edit feature layers on a map, query data repositories, and analyze data. You can also easily add related documents, drawings, and photos, as well as review any related information added by others.
After a disaster, imagery is traditionally collected from a host of platforms and sensors mounted on satellites or aircraft. Due to the large size of the image products, requested images are traditionally received and distributed via external hard disk. This traditional distribution system encourages unnecessary duplication of data, delays in the receipt of needed data, and the creation of non-standard GIS products.
Time saved means lives saved, and ERDAS APOLLO enables you to quickly organize the massive volumes of mission-critical data created after a disaster and clearly present it to first responders and relief agencies. Agencies can then access the catalog and relevant map displays, and consume data and services in a variety of applications and mobile devices.
