To implement or transition to the map validation process in Alert Responder™, the following requirements must be met. After your map data is reviewed, the process should be thoroughly tested in your live training environment to ensure accuracy. Successful map validation depends on highquality map data—precision is essential.
Required independent map layers:
ESN
EMS Responding Agency
Fire Responding Agency
Law Responding Agency
Census Tract
Zip Code
City
Law Grid
Fire Grid
EMS Grid
Optional Layers based on user requirements and expectations
EMS Reporting District
Fire Reporting District
Law Reporting District
Run Card
Subdivision Name
MABAS Box
Address Alerts
Intersections
Hydrant Data
Postal City
Township
For the address locators, the following fields are required:
Roads layer
street name
address ranges
community left and right
Address points
house number
street name
community
For network routing the following fields are required in the roads layer:
speed limit
one-way
Each map layer must include a layer ID that corresponds to the information in the database if one already exists. When creating a new database, consistent and appropriate naming conventions must be applied.
The map control settings must then be configured to ensure the correct information is retrieved during location validation. Two primary scenarios must be considered: point-based validation and intersection-based validation. Point-based validation, such as addresses or wireless locations, is straightforward. The system queries the shape files at the point’s location and returns the associated information. Intersection-based validation is more complex, particularly when the intersection lies between multiple shape files. In these cases, the dispatcher must determine the correct result using the left/right side settings defined in the map data.
It is critical that layer lines are continuous, without gaps, and that they align precisely with one another. This ensures that information can be retrieved from any location on the map. Although this requirement can be challenging, every shape within a layer must be complete to guarantee accurate and consistent results.
