The DATAMARK® VEP suite of products provides 9-1-1 jurisdictional authorities and stakeholders the ability to review and edit their GIS data in the context of meeting NENA NG9-1-1 standards. The application allows individual jurisdictions to run validation checks against mission-critical spatial data. They can subsequently add, maintain, and perform reviews as part of ongoing data remediation and maintenance efforts. DATAMARK VEP allows users to add and maintain address points, road centerlines, and emergency service boundaries for their jurisdiction. Multiple users can run validations and subsequently edit and remediate their data simultaneously through a customized web portal and notification workflow, as their changes are routed for review and approval by an administrator. Once approved, edited or newly added map features are available in the default database to continue with the data remediation and data maintenance life cycle.
