This application provides information and tools to allow landowners, decision-makers, and the general public to observe crop rotations for a four year cycle.

The crop rotation analyst allows a user to create specialized or generalized queries of crop rotation combinations. The results of the crop rotation query are displayed on the map and classified according to the amount of area that falls within a specific crop rotation combination. The results are sorted from largest to smallest area. A selected result will display red in the map with all other results showing in black. Each area (pixel) on the map represents a 30 meter square area that is identified by the use of a constant color mapping classification against all query results. More information on how to use the tool can be found in help.

In 2011, the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) expanded the process of generating annual crop inventory digital maps using satellite imagery to include British Columbia, Ontario, Quebec, and the Maritime provinces, in support of a national crop inventory.

In 2012, the process was expanded using satellite imagery for all of Canada (except Newfoundland).

In 2013, 2014, 2015 and 2016 the process has included satellite imagery for all of Canada in support of a national crop inventory.

A Decision Tree (DT) based methodology was applied using optical satellite (Landsat-5 and DMC in 2011; DMC and SPOT in 2012; Landsat-8 in 2013 and 2014) and radar (RADARSAT-2) imagery, with a final spatial resolution of 30m. In conjunction with satellite acquisitions, ground-truth information was provided by provincial crop insurance companies and point observations from our regional AAFC colleagues.
