The Ontario County High Points List was created by Greg Slayden of Peakbagger.com. Ontario is administratively divided into 51 units that are a mixture of counties, unified counties, regional municipalities, districts, cities, and municipalities. Elevation measurements were taken from the 1:20,000-scale Ontario Base Maps (OBM) series produced by Ontario’s Ministry of Natural Resources. These maps feature a 10-metre contour interval and an extensive set of spot heights for which the ministry reports a vertical accuracy of 2.5 metres. Contour interval accuracy is 5 metres. All the spot elevations in the OBM data were downloaded, matched to their county by a point-in-polygon operation, and the highest spot elevations picked out. When encountering multiple spot elevations of the same height in the same general location, one representative point was picked. Also, some OBM spot elevations were clearly erroneous outliers and had to be discarded. In general, a 1-meter difference in spot elevations was considered significant, and these lower points were not considered high-point candidates.
