This spatial data set contains lines representing 1 meter Elevation Contours from the 2018 Ortho delivery.
This spatial data set contains lines representing 1 meter Elevation Contours from the 2018 Ortho delivery. This layer is a merge of the tiled vector line delivery. The ortho-imagery from which the contours were derived was acquired through the Niagara Region 2018 Digital Ortho-Photography Project, a collaboration between municipal government, utilities, and educational institutions. The imagery was acquired in the spring of 2018, with a minimum horizontal and vertical accuracy of 50 cm, tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 50cm RMSEz Vertical Accuracy Class. Actual non-vegetated vertical accuracy was found to be +/- 40.41 cm, and vegetated vertical accuracy was found to be +/-61.85 cm at the 95% confidence level. The 2018 DTM is an update of the original DTM created in 2002, and subsequently updated using 2006 and 2010 imagery. The 2010 updated DTM was commissioned and supplied by the Niagara Peninsula Conservation Authority (NPCA) to support this data set.
