Notice of Landbase Map Object Change Freeze


The Member Mapping application will be unavailable during our annual Landbase map maintenance, part of our ongoing effort to keep maps current.


 MAINTENANCE DATES (Eastern Standard Time):

     Map Update Freeze BEGINS – Thursday, December 9, 2021 (2359)

     Map Update Freeze ENDS – Monday, January 3, 2022 (an email will be sent)


Beginning December 9th at 2359, access to update map objects and services will be temporarily frozen. This means both the “Member Mapping” and the “Member Mapping - Upload your map data” applications will not be available.

If a notification area needs to be added during the freeze, it will be necessary to revert to municipal level notification until after the Landbase maps are active again on January 3, 2022.

This maintenance is critical because the Landbase map data is used by members as reference points when designating facility notification areas, and by both web ticket entry users and customer service reps when drawing excavation notification areas. Both the facility notification areas and the ticket entry maps are used to determine which locate requests / tickets are sent to each Mapped Member.

If you have any questions, please contact Member Services at membership@pa1call.org or 412-464-7168 or 800-248-1786 ext. 7168.

Thank you for your patience as we update our Landbase maps.
