1934 Air Photos of Niagara Region Coordinate system: 4269 - "NAD83" Abstract: This data set is a scanned reproduction of the 1934 air photos from the Canada Department of Energy, Mines, and Resources, held in the Brock University Library collection. This image service provides a mosaic of the geoTIFF images (aerial photographs) for the Niagara Region. The coverage area includes the Niagara peninsula from approximately, Grimsby, Ontario in the west to the Niagara River in the East and Lake Ontario shoreline in the North to Lake Erie shoreline in the south. This image service was updated in December 2017 to provide enhanced georeferencing and edge matching.

  Process step:

  Map, Data & GIS Library, Brock University: Original air photos in the library collection were scanned at 600 dpi; mosaicked into sections; and georeferenced in Geographic Imager to create the GeoTIFFs.

  National Air Photo Library (NAPL): Original photos are part of the Canada National Air Photo Library (NAPL) of Natural Resources Canada and are held in the Brock University Library collection. NAPL archives over six million aerial photographs covering all of Canada, some of which date back to the 1920s.
