Odor Complaint Viewer
PurposeThe Odor Complaint Viewer (OCV) is a tool for Dispatch to monitor odor calls/complaints
The system will graphically display odor and priority/emergency orders
Automatically posted when created in our customer information system
Manually posted for all other odor complaints
New orders posted to the map will appear as a bull's-eye
Previous orders will appear as either a red flag or red push-pin as clear visual reference
Legend
Order Location
ProcessThe dispatcher will enter the address, city & state OR the cross streets.
Verify the date range – three-months
Evaluate the area around the new order Check the attributes of the push-pins and flags within
a 500 ft. radius.

Process
ProcessIf there are flags and/or pins and these orders were all inside odor complaints that showed repair, turn off, etc., and the underground leakage investigation was negative, then no further action is required for those addresses
If the object on the map was a flag and the order was an outside odor call, then these addresses require an automatic recheck of the facilities
Any pins that show no resolution, either research the original order to find the resolution and input that information into the system or route the address for a recheck
Manual Input
Manual InputSometimes an order will come in where there is no address in our customer information system, such as an intersection, all electric, propane address, etc.
The dispatcher can add a location by two different methods
Type in the address if known
Click a location on the map and the Latitude/Longitude fields will be populated for the location
Resolution Comments
Computer generated orders will automatically update with field technician comments when completed
Manually input odor locations must be updated by the dispatcher
Other Tools
Other ToolsZoom into a specific area
