Trimble SX12 Scanner Elevation Data for the Little Red Shop Local Historic District, BLRV

Metadata Updated: September 26, 2025

The dataset includes 5 panoramic scans of the buildings, cultural resources, and other features within the National Park Service boundaries at Roger Williams National Memorial. The scans exist as point cloud files in Trimble Business Center. Each scan has at most 24 panoramic photographs associated with it, depending on whether it was a horizontal band or polygon scan. The points have been colorized based off the panoramic photographs and have been categorized into regions, such as buildings, ground, poles, and trees. There is a layer of points selected from the bottom of doorway thresholds to capture the finished floor elevation data. There is also a layer of points representing the elevation of first floor windows and basement windows. Each point in the layer has elevation data and latitude and longitude data associated with it. The layers are exportable into ArcGIS Pro as point layers, and the data associated with each point layer is exportable as a CSV file. The data was collected in NAD83 (2011) meters UTM Zone 19 and NAVD88. The controller used was a Trimble TSC7 data collector. Control points were set using the BOHA NTRIP base station, an R12i GNSS receiver, and a prism. Scans were completed using a Trimble SX12 scanner that was set so that points would be 2 cm apart at 20 m with a scanning distance of 200 m and a scanning radius of 1 m from the scanner. The scans were performed using the coarse resolution, stored in Trimble Access, and exported to Trimble Business Center.
