Title

Orthomosaic imagery for the South Saskatchewan River, Canada

Abstract

Data were collected in 2015, 2016 and 2017 to provide high resolution imagery for two sections of the South Saskatchewan River, Canada. Photographs were acquired using conventional aerial plane images with a 0.06m ground resolution, captured at a height of approximately 1500m from a fixed-wing aeroplane with an UltraCamXp sensor. Imagery was obtained on four occasions (13th May 2015; 2nd Sept 2016; 8th June 2017; and 12th June 2017). The dataset consists of eight orthomosaics; one for each of the two river sections on each of the four dates. Images were collected as part of NERC project NE/L00738X/1.

Lineage

This dataset consists of geolocated aerial orthomosaics of the South Saskatchewan River, near Outlook Canada (UTM Easting and Northing coordinates: 356500, 5712400; Latitude and Longitude: 51.5 N, 107.07 W). Photography was acquired to provide high resolution imagery of the river bed and surrounding valley floor on four occasions (13th May 2015; 2nd Sept 2016; 8th June 2017; and 12th June 2017) and for two separate sections of the river. Images were obtained using conventional aerial plane photography with a 0.06m ground resolution, captured at a height of c. 1500 m from a fixed-wing aeroplane with an UltraCamXp sensor. The orthomosaic was generated from the aerial photography (using up to 160 individual images for each orthomosaic) by automated image matching using the SfM program Pix4D (https://pix4d.com/) with the ‘large frame’ supplementary software package. Bundle adjustment was undertaken using Pix4D’s key point matching system optimised for aerial nadir imagery. Camera properties were specified using calibration certificates and were not allowed to vary during the calculation. The orthomosaic image file includes UTM Easting and Northing coordinates that can be viewed by opening the image in a GIS or other image handling software.
