BTM ( Baseline Thematic Mapping) Landsat Image Catalogue Acquisition Dates. This polygon coverage contains the date of capture of the Landsat images making up the seamless BC Landsat image catalogue. This is not a multipart feature

Polygons containing the date of capture of the Landsat images used to create the first version of the Baseline Thematic Mapping v1 (BTM1). This spatial view is only meaningful in conjunction with the satellite images or the BTM data derived from the satellite images. The images were captured from 1990 to 1997

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__. Satellite image mosaics are products designed by combining several adjacent tiles of satellite images from the Landsat or Sentinel sensor. The coverage of the mosaics varies according to the years of acquisition, ranging from southern Quebec to all of Quebec. These mosaics are designed to identify land use classes, including forest environments, agricultural environments, wetlands, and environments modified by humans. They also offer an overview of the various natural disturbances that occur on the territory. In the end, they offer easy monitoring of the evolution of forest cover and natural disturbances across territory and time. These mosaics are primarily used to support planning, monitoring, and land use planning. The resolution of the mosaics ranges from 10 to 30 meters.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
