Landsat-5 Imagery [Ontario]

Description
The Landsat-5 Thematic Mapper data includes enhanced mosaic segments covering the province of Ontario. The imagery has been resampled to a resolution of 25 metres.

These files are three-band false colour infrared composites, consisting of the green visible band shown in blue, the red visible band shown in green and the nearest infrared band shown in red. This results in an image where healthy summer deciduous vegetation appears in shades of red; deep clear water appears almost black; and sediment loaded water appears as bright turquoise. Very recent forest cutovers and infrastructure (bare soil) appear almost white.

The dates range from 1984 to 1995.

These data are made available through the Ontario Geographic Data Exchange (OGDE) program as part of the Land Information Ontario (LIO) data warehouse.
