inSITE’s VOICE application for quality control allows geospatial data end users and vendors to collaborate in real time on large datasets. Cloud-based quality control increases the speed of geospatial projects by eliminating shipping and on-site data distribution and reduces costs by eliminating the need for specialized desktop software. Organizations using VOICE can distribute quality control tasks to large groups of reviewers, who can view and analyze data through inSITE’s web interface. Vendors receive instant georeferenced feedback on their work in a standardized format, helping them resolve issues quickly.
Data Tiles
Your quality control team will review and make QC calls on the individual data tiles that comprise your overall dataset or imagery mosaic. Data or imagery resolution (e.g., 6 inches=1 pixel) is determined by your team and your vendor. VOICE supports any data resolution.
Quality Control Roles
Your organization’s inSITE administrator will assign each member of your quality control team a role. The available roles are admin, screener, reviewer, vendor, and general. All users may view geospatial data and QC calls, but other privileges depend on the user’s role.
Admins direct quality control efforts. Admins may add or delete users from the quality control team, manage user accounts and passwords, and assign tiles to users for review. Admins may also complete or fail tiles, create QC calls, approve or reject QC calls, update the status and attributes of QC calls, and delete QC calls.
Screeners act as team leads for quality control. Screeners may complete or fail tiles, create QC calls, approve or reject QC calls, and update the status and attributes of QC calls.
Reviewers are team members who perform quality control tasks. Reviewers may complete or fail tiles and create QC calls.
Vendors are team members who receive, review, and resolve issues identified during quality control. Vendors may approve or deny QC calls made by reviewers.
General users are team members who do not directly participate in the quality control process. General users may only view issues calls and tile status.
QC Calls
QC calls are georeferenced tags that reviewers use to identify issues with data tiles. A call consists of a bounding box specifying the issue’s location and a description of the issue.
VOICE provides three types of QC calls for imagery datasets: Seamline Anomaly, Elevation Anomaly, and Image Anomaly. Each issue type has several subtypes based on common geospatial imagery production errors. For more information on call types and subtypes, see QC Call Definitions. If your instance of VOICE is configured for another data type (e.g., LiDAR or geospatial vectors), VOICE will display QC calls configured for your quality control project and data type.
Call Status
VOICE assigns a status to each QC call created by a reviewer. Screeners and admins can update the calls status. Reviewers, vendors, and general users can view the call status.
- Reported is the default status and means a reviewer has created the call.
- Rejected means a screener or vendor has viewed and rejected the QC call as invalid. No vendor action is needed for the call.
- Submitted means a screener has viewed and validated the QC call and submitted the call for vendor review. The vendor must review and approve or reject the call.
- Resubmitted means a screener has viewed a vendor resolution but does not accept the resolution and has resubmitted with comments for another vendor review. The vendor must review and approve or reject the call.
- Accepted means the vendor has indicated the issue is invalid or no effective resolution is possible and the screener accepts the vendor’s assessment. No further vendor action is needed for the call.
- Confirmed means the screener has viewed and validated a vendor resolution for a QC call and accepts the vendor resolution. No further vendor action is needed for the call.
Tile Status
VOICE assigns a status to each data tile after review.
- Passed means a reviewer completed the tile without identifying any issues.
- Error means the tile contains 1-2 QC calls.
Failed means the tile contains 3 or more QC calls or a reviewer manually failed the tile because of a systematic error.
