Tree Line
ITD; SWAAI; ITIP Project Key #23747; Cyclomedia
Tree areas near the roadway, including square footage, average/minimum/maximum height, and minimum distance to roadway. Strike potential for fallen trees is determined by comparing whether the minimum distance to roadway is less than the maximum height of the tree area.
Core Attributes These attributes are common across all feature classes extracted as part of the SWAAI project where applicable.
- UniqueID Unique ID for this feature type, assigned by Cyclomedia staff. This ID matches the same feature in previous SWAAI iterations where applicable.
- Route Highway route name derived from RouteID of closest mainline.
- Milepost or FromMilepost/ToMilepost Approximate milepost (in the case of discrete point features) or approximate from/to mileposts (in the case of line or polygon features) based on milepost-based LRS network provided by ITD.
- ForemanArea ITD foreman area based on boundary file provided by ITD.
- District ITD district based on boundary file provided by ITD.
- RouteID Route ID based on ITD’s Esri Roads & Highways linear referencing system (LRS).
- RouteDirectionCode Travel direction of nearest highway lane to feature, ascending (A) or descending (D).
- Measure or FromMeasure/ToMeasure LRS measure (in the case of discrete point features) or from/to LRS measures (in the case of line or polygon features) based on ITD’s Esri Roads & Highways LRS. - SideOfRoad Side of road location of feature, generally L (left) or R (right). Values for B (both), C (center), and N (neither) were also included as text domain values for use where applicable.
- X/Y/Z or From_X/To_X/From_Y/To_Y/From_Z/To_Z Longitude (X), Latitude (Y), and Elevation (Z) values were included for each extracted feature (X/Y/Z for discrete points, to/from X/Y/Z for lines and polygons) Rather than the metric northing/easting present in the Idaho Transverse Mercator (IDTM, WKID: 8826) projection, the projection used for all SWAAI datasets, X and Y are decimal-degree latitude/longitude. The elevation field, Z, is in U.S. feet. - StreetSmartLink URL link to the feature’s location in Cyclomedia’s browser-based Street Smart photo and LiDAR depth surface viewer. Following the link brings the user directly to the closest Street Smart collection location and angles the view to look directly at the feature in the 360° photograph.
- Comments General comments field.
- CollectedDate Date the feature was observed and field-collected by Cyclomedia during the vehicle-based data collection process.
Key Attributes These attributes are unique to this feature class or are Core Attributes used differently than other feature classes extracted as part of the SWAAI project.
- Quantity_sqft Total square feet of tree area identified.
- AverageHeight_ft Average height of trees within tree area, in feet.
- MinimumHeight_ft Minimum height of trees within tree area, in feet.
- MaximumHeight_ft Maximum height of trees within tree area, in feet.
- MinimumDistance_ft Minimum distance from edge of tree area to roadway, in feet.
- Strike Indicates if the minimum distance is less than the maximum height signifying a potential tree strike on the roadway.
These data were derived by Cyclomedia Technology as part of ITIP Project Key #23747, FY 2023 Statewide Asset Attribute Inventory (SWAAI), using a combination of automated, semi-automated, and manual processing. The original SWAAI project was an FY 2020 Idaho Transportation Department (ITD) pilot project to perform vehicle-based LiDAR (Light Detection and Ranging) and roadway photography data collection on Idaho’s full state highway system, including interchange ramps and rest areas. Following collection, these data were used to extract a list of deliverable GIS roadway asset datasets according to ITD’s specifications. The FY 2023 SWAAI project is intended to refresh, improve, and expand on the original 2020 data, and the UniqueIDs of all 2023 features are tied back to their original 2020 features via change detection when applicable.
