What is ArcGIS Data Reviewer

To produce high-quality information products and perform accurate spatial analysis, your source data must be of high quality and well maintained. ArcGIS Data Reviewer enables management of data in support of data production and analysis by providing a complete system for automating and simplifying data quality control that can quickly improve data integrity.

Data Reviewer provides a comprehensive set of quality control (QC) tools that enable an efficient and consistent data review process. This includes tools that support both automated and semiautomated analysis of data to detect errors in a feature's integrity, attribution, or spatial relationships with other features. Errors detected during analysis are stored to facilitate corrective workflows and data quality reporting.

Automated data review

Data Reviewer-enabled services allow clients to implement automated data review using checks configured using either ArcGIS Data Reviewer Desktop or ArcGIS Pro. These services leverage ArcGIS Server to carry out automated review using an organization's on-premise or cloud-hosted infrastructure. In a production environment, services-based data validation can be scheduled on a nightly basis to assess data created or modified during regular business hours. Alternatively, automated review can be triggered on an as-needed basis to support ad hoc assessment of data quality as a component of a data management workflow.

Semiautomated data review

Not all errors in your data can be detected using automated methods. Semiautomated review is the process of assessing data quality using methods that typically involve guided workflows requiring some human interaction and input. Visual review is predominantly the most common form of semiautomated review and is used to assess quality in ways that automated data review cannot. This includes the discovery of missing, misplaced, or miscoded features and other issues that automated checks may not detect.

Data Reviewer services support these workflows by enabling client applications to create error results using geometry and attributes from existing or temporary web features. For example, you can enlist users of your web applications to help identify data errors using a simple Report Error workflow. The feedback is stored as an error result, where it is reviewed and either rejected or allowed to pass on to technicians for correction as any other error identified by Data Reviewer would be. The geodatabase serves as a centralized place for managing errors detected using automated checks and errors detected manually by data consumers.

• Write Result (REST API)

Results management

Data Reviewer enables comprehensive management of results from detection through correction and verification. These capabilities increase efficiencies in improving data quality by identifying the source, location, and cause of the errors. Costs are reduced and duplicative work is eliminated by providing insight into the status and how it was detected, who corrected it, and whether the correction has been verified as acceptable.

Data quality reporting

Data Reviewer-enable services provide both summary and detailed reporting of data quality results. These services are used to communicate the source, quantity, severity, and location of noncompliant features detected in your data. Noncompliant features include those detected using Data Reviewer automated checks or feedback provided by data consumers in the form of markups.

By communicating data quality, you can alert stakeholders and other interested parties when data does not meet agreed-upon standards and provide a reporting method for tracking data compliance through time. Reporting capabilities can be integrated as a component of an organization's overall business performance management system or as a stand-alone dashboard for reporting data quality.
