Moving to World Geodetic System (WGS) 84 in a Live GIS Environment to Leverage Google Maps
It’s easy to focus on field staff efficiency with accurate data by leveraging the latest mapping technology and projection systems when you are creating your GIS infrastructure from scratch… but how do you migrate to a mapping technology like Google Maps that is based on a particular geodetic standard to drive efficiency when your LIVE system is based on a different datum?
A leading telecom services provider in the Middle East engaged Avineon to help them leverage Google Maps to gain Field Staff Efficiency across the organization.
Statistics showed inaccurate location information, even by a few hundred feet, led to a failed or inefficient result in at least 20% field visits.
With the data accuracy of moving to Google Maps, the telecom provider hoped to increase the accuracy of work locations, facilities and customer site visits for field crews. Even the slightest efficiency in field staff operations could result in quicker service, shorter outages and resource optimization. The challenge of migrating to Google Maps was the need to transform geodetic datum of their land base and network data from a local datum (AIN El ABD 1970) to the universally accepted datum WGS 84 with minimal downtime of a LIVE system and zero impact on the work order update process.

Though the industry average is to focus on 5 transformation parameters in a change of this magnitude, Avineon defined and engineered 7 transformation parameters to increase positional accuracy using nationwide ground control point network along with the standard parameters needed by WGS 84. With Avineon’s extensive ESRI technology expertise, a custom tool was developed in ESRI ArcGIS and Ericsson Network Engineer, to automate the datum transformation of the LIVE system in a minimal amount of time.
For the transition, Avineon created a strategy to maintain uptime for the LIVE system with a complete system rollout all at once instead of the proposed area by area transformation originally intended by the client. While maintaining any open and pending work orders in parallel systems, the transition exceeded timeline expectations and leveraged Avineon’s experience handling LIVE operations in a transformation process while maintaining maximum uptime for all business units.

Not only did Avineon assist the telecom provider to see improvements in overall service and shorter outage times but the transformation also helped the client save close to 15% on field staff time responding to sales and trouble calls. With the additional benefit of integrating network maps, operational staff was able to achieve further efficiency in routing field staff to facilities/customers.
