CREATING A GEOPROCESSING MODEL FOR MAUI’S E911 Abstract Enhanced 911 (E911) is a system that automatically pinpoints a wireless caller’s physical location. The E911 system holds Geographical Information System (GIS) data that helps locate the caller for the appropriate emergency service. Since Maui is growing rapidly, many new roads, buildings, and subdivisions are being built. The emergency database must be updated to ensure safety. The goal of this project was to create a geoprocessing model that would update different data layers into the E911 system automatically. The model takes new subdivision and Tax Map Key (TMK) information and uses the appropriate tools and processes to translate the data into GIS data. Then the GIS data can be added into the emergency database. Maui has not been able to update their TMK GIS data since 2006. In two years, over 300 changes have occurred, and manually updating the GIS layers has become impractical. This new automatic geoprocessing model will ensure that new data is being updated into the system. This will allow operators to find callers faster and save lives, no matter the location of the call.

Step 1: Selects the CAD lines and data that make up the new subdivision parcel and creates GIS Data
Step 2: Selects the points or labels of the Lot Numbers that contain Tax Map Key Information
Step 3: Selects the points or labels of the Lot Numbers within the new subdivision parcel
Step 4: Updates new Tax Map Key Information and creates new GIS subdivision parcel with TMK Information
Attribute Tables of Subdivision Parcel Lot Numbers without and with Updated Tax Map Key Information

Since each new subdivision onMaui County is at a differentlocation, the new GISInformation must be put into the911 Database System Manually.
The subdivision will betranslated by either hand or theuse of a geographicalbenchmark into the Tax MapKey. A geographical benchmarkis a stationary object used bysurveyors to pinpoint thelocation of roads andsubdivisions. The geographicbenchmark has its own Latitudeand Longitude Coordinate. Fromthis coordinate the 911 centercan calculate the X,YCoordinates of the newsubdivision parcel.
These new updates will:• Provide the 911 operator
with enough informationto alert and emergencyservice
• Cut down the responsetime
• Help save lives
