New Brunswick Aerial Imagery available for Download
The Province of New Brunswick recently added a new online web application to their arsenal of online mapping and data tools. The new online web application, they call the NB Imagery App allows the public to download close to 5,000 square kilomters of high resolution digital aerial imagery acquired throughout New Brunswick between the years 2014 and 2017 available at a variety of image resolutions.

The Province of New Brunswick is not new to the open data world and has already been providing free download of their orthophotomaps for the entire province (1996 – 2002), however this new application now provides Canadians with access to more detailed and updated imagery.
An orthophoto is a geometrically corrected aerial photograph. It is generated when the effects of tilt and terrain relief are removed from the aerial photograph by a process called orthophoto rectification, allowing for ground features to be displayed in their true ground position. This allows for the direct measurement of distances, areas, and positions (if printed at scale or used in a Geographic Information System).
An orthophoto may serve as a base layer onto which other map information may be placed over. When two or more orthophotos are merged or mosaiced together then clipped to a specific area, an orthophotomap is created.
