Algonquin 2015 Orthophotography

The orthophotos are considered foundational data and will be used in GIS analysis, remote sensing analysis, mapping, asset management, environmental management, planning, and for background reference data.

Use the Geospatial Ontario Imagery Orders App to select and request uncompressed or compressed digital imagery tiles from Geospatial Ontario for transfer directly to you.
 

For more information and to order stereo imagery products, please refer to the GEO Stereo Imagery Order Form.

Algonquin Orthophotography was acquired in the spring of 2015 under the best conditions possible to achieve cloud free, snow free, ice free, smoke free, and leaf off captures. The orthophotography has a pixel resolution of 20 centimetres and the horizontal positional accuracy of this data set is 50 cm at the 90% confidence level. The imagery was acquired by an ADS100 Leica digital camera and was later orthorectified using an elevation dataset generated through image correlation.
