Motionworks Viewcast provides media metrics including Circulation, Opportunity to See (OTS) and Likelyhood to See (LTS) impressions for exposed audiences that are visiting assigned places or traveling along paths assigned to the media. All assigned paths and places are measured and aggregated to report deduplicated audience exposure and impression profiles.

For details on viewshed creation, traffic measurement, and how circulation is converted to Opportunity to See metrics, see Viewcast Methodology.

Versions

Each Viewcast Profiles release combines a place-based traffic feed (sourced from Placecast by Date) with a roadside traffic feed, measured over a fixed forecast window — the range of months whose measured traffic is aggregated into the published Circulation, OTS, and LTS metrics. Two versions are currently published. The placebased_version and roadside_version fields on every record identify the exact feeds used to build it.

Version	Place-based feed (placebased_version)	Roadside feed (roadside_version)	Forecast window
V1	Placecast v2_2	tt3	September 2023 – August 2024
V2	Placecast v2_4	tt3	January 2025 – December 2025

The two versions share identical viewshed geometry and face assignments; they differ only in the underlying place-based feed and the forecast window. The forecast window of a record is also reported directly in its period_start and period_end fields. History reported in the history and by_year fields extends further back than the forecast window (see Historical Summary).

Data Dimensions

• Frequency: Published monthly. Data products are incremented one month after the end of each month, within 6 weeks of the close of a month.
• Geographic coverage: Summarizes traffic in any viewshed area within the United States.
• Date availability: Historical data available back to 2019 with monthly and annual aggregations.
• Latency: Data are released within 6 weeks of month close. For example, January 2025 will be incremented no later than March 15, 2025.

  Geopath Structure

Geopath inventory metrics matched to this viewshed. When a face has a corresponding Geopath record, these fields provide the industry-reported metrics for direct comparison.

  "spot_ots": 31661,
  "spot_lts": 28495,
  "encoded_media_type": "20",
  "spot_count": 3
}

• face_id: Geopath face identifier
• spot_id: Geopath spot identifier
• face_traffic: Geopath-reported weekly face traffic
• face_circ: Geopath-reported weekly face circulation
• spot_circ: Geopath-reported weekly spot circulation
• spot_ots: Geopath-reported spot Opportunity to See
• spot_lts: Geopath-reported spot Likelihood to See
• encoded_media_type: Encoded classification type, media type, and digital capability (see Encoded Media Type Reference)
• spot_count: Number of distinct Geopath spots on this face

Encoded Media Type Reference

The encoded_media_type field encodes the Geopath classification type, media type, and digital capability into a single string identifier.

Special Classification Codes

Non-roadside classifications use fixed codes:

Code	Classification	Digital
990	Place Based	Yes
999	Place Based	No
980	Fleet Exterior - Dynamic	Yes
989	Fleet Exterior - Dynamic	No
970	Fleet Exterior - Scheduled	Yes
979	Fleet Exterior - Scheduled	No

Roadside Codes

Roadside classifications combine the media type ID with a digital suffix:

Code	Media Type	Digital
11	Murals	Yes
10	Murals	No
21	Bulletin	Yes
20	Bulletin	No
31	Poster	Yes
30	Poster	No
41	Junior Poster	Yes
40	Junior Poster	No
51	Panel	Yes
50	Panel	No
61	Display	Yes
60	Display	No

Last digit: 1 = digital, 0 = static.

Sentinel Values

• NULL -- No Geopath match (face not in Geopath inventory)
• '' (empty string) -- Cluster-level aggregate in tiles (no individual encoding)

Viewshed Corrections

Some roadside faces are submitted with an orientation or size whose viewshed does not reach any drivable road. Left uncorrected, such a face has no road on which to measure a path and would report zero traffic. To prevent this, Motionworks automatically applies the smallest adjustment that lets the viewshed reach a road — a new orientation, an enlarged face, or both — so that a path can be built and measured.

When a face is corrected, the face_orientation, face_height, and face_width reported in this feed reflect the corrected values. The values as originally submitted are preserved on the source viewshed record and are not lost. Faces where no adjustment can reach a drivable road are left exactly as submitted and are reported with a No Valid Paths assignment status.

Assignment Status Values

Status	Description
Industry Assigned	Path assignments agree with Geopath assignments.
System Assigned	Motionworks system-generated assignments that differ from Geopath.
Motionworks Assigned	Paths manually assigned by Motionworks team.
Unverified Assignments	Assignments not yet validated; queued for manual audit.
No Traffic Data	The face's valid paths carry no measured traffic within the release's forecast window. Applies to both roadside and place-based faces. Metrics are reported as zero rather than omitted.
No Valid Paths	A roadside face for which no valid, measurable path could be built — the viewshed reaches no drivable road (see Viewshed Corrections). Takes precedence over No Traffic Data.
