Past Projects: Enhanced LandSAT Images of Trout Lake
A common misconception about satellite images, are that they are like aerial photographs but from space. But they are actually very different from aerial photographs. Satellites use remote sensing techniques to collect information digitally, and then computer software is used to convert that information into various types of derived images.
The satellite images below are a few enhanced Landsat Satellite images of Trout Lake, Nova Scotia (popular fishing place on the South Mountain – south of the town of Middleton) that were enhanced using PCI Geomatica.
Landsat 7
Landsat satellites carry sensors that record “light,” or portions of the electromagnetic spectrum, as it reflects off the Earth’s surface.
Landsat 7 is the seventh satellite of the Landsat program. Launched in 1999, Its’s primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. [wikipedia.org]

The first image (below on the left) is a True Color Composite (TCC) showing bands 3,2 an 1. The second one (below on the right) is a False Color Composite (TCC) showing bands 7,4 and 3 and helping to clearly define the various clear cuts in the area.
