DRAPE Imagery (Digital Rastor Acquisition Project for the East) was received from the Ontario Ministry of Natural Resources. The imagery covers approximately 54,000 square kilometres in eastern Ontario and was taken between January 2008 - January 2009. Imagery is available in either 1 km tiles or mosaiced 20 km tiles.
Data collection came from multiple remote sensing data products at 30cm and 10cm resolution. The Province of Ontario managed the imagery and made available a resampled 20cm version of this data.
Over 50 organizations contributed funding to the project including: Ontario Government ministries, municipalities, Conservation Authorities, private sector organizations, non-government organizations and a few federal departments.
