NG9-1-1 Dataset Improvement Project – Terra Systems Southwest

NG9-1-1 Dataset Improvement Project (NDIP)

Client: Arizona Department of Administration
2018-Present

Four NG 911 Data Improvement Projects (NDIP) were approved in July 2018. They are targeted at four rural counties that previous data evaluations had shown needed significant work on some or all of their NG 9- 1-1 databases. Work includes a comprehensive assessment of GIS data set errors, the development and implementation of a data correction plan to fix the errors found, and the creation of data maintenance workflows to help ensure sustainable NG datasets into the future.

TSSW provides project management, data conversion, and quality assurance services. This includes working directly with 9-1-1 System staff and resources in each County. NG Data sets for address points and emergency service boundaries are being processed. Final data will be provided in NENA NG9-1-1 data schema along with various quality assurance fields for tracking changes in attributes and spatial location of address points. In addition, the NG GIS road network data and open source Bing footprint data are being cross referenced and used to check for missing roads and address points. The road network will be updated to reflect new emergency service boundaries.

Data Points

Several hundreds of thousands of points will have been evaluated and updated as a result of these projects.

Scripting

Data update and quality assurance procedures have been developed and some tasks automated through scripting.

Boundaries

Emergency Service Zone and Community Boundary polygons will be updated with those new attributes transferred to NG address point and road network databases.

Workflows

Key data maintenance workflows are being researched and documented to help 9-1-1 System Administrators and their GIS support staff keep their datasets up to date.

TerraSystems Southwest has proven to be an instrumental part of the success achieved in the projects they have participated in for the Arizona 9-1-1 Program. The level of expertise possessed by TerraSystems Southwest along with their professionalism provides confidence in their abilities to accomplish any goal that may be presented to them. Their willingness to participate, the guidance they have provided and the flexibility which has been needed many times is a testament to their level of commitment.
